[0002] At present, the status of thermal sealing, thermal management design and thermal simulation of hypersonic aircraft cabins is that most of the work is still in the stage of single technical research or single-point problem simulation. The common characteristics of existing cabin designs are that they mostly adopt passive thermal design solutions that rely on the temperature resistance of materials, and mainly focus on one-time, short-time flight, ablative thermal protection technologies such as hypersonic missiles, space shuttles, and spacecraft. The cabin wall structure design is highly redundant, resulting in the aircraft's structural weight for thermal protection accounting for more than 30%, and after adding the weight of the load-bearing cold structure, the proportion is close to 50%; there are problems such as high structural weight cost, serious space volume occupation (the thickness of the insulation layer can reach 10~25mm), poor impact resistance, low thermal design efficiency and limited service life. At the same time, the thermal sealing design of the switch cover on the cabin surface is less considered, and simulation analysis is mostly carried out according to independent closed cabins, which makes it impossible to finely analyze the dynamic thermal boundary of the cabin heat source, and the cabin thermal management system is inefficient, and more weight costs are also paid.

[0056] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0057] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0058] Based on the current status of background technologies, the following challenges are faced:
[0059] a. Existing research on thermal seal structures is mainly based on verification tests. There are few theoretical and simulation studies on their thermal gas response laws and thermal seal effectiveness. There is a lack of systematic quantitative research on thermal seal leakage performance and heat transfer characteristics. It is unable to support the design of hypersonic aircraft thermal seals and thermal seal effectiveness analysis. It is urgent to further establish corresponding evaluation models and simulation methods, and use typical tests to verify and correct the corresponding evaluation models.
[0060] b. Research and simulation technologies based on single-point thermal management technologies such as spray cooling and water heat exchangers are relatively mature, but there is a lack of evaluation of the overall heat dissipation characteristics under the coupling of multiple heat sources in low-pressure and variable-pressure cabins; in terms of research methods, experimental research is the main method, the optimization cycle is long, there are few reference materials for model-based simulation research, the correctness and accuracy are not fully verified, and there is a lack of systematic research on coupled thermal sealing and flow and heat transfer in the cabin.
[0061] c. Traditional cabin thermal design methods have the characteristics of weak coupling, strong repetition, and low precision, and are not suitable for the actual cabin temperature control problems of hypersonic aircraft. It is urgent to develop an integrated agile design process and method.
[0062] Hypersonic aircraft emphasize reusability (more than 100 takeoffs and landings) and long-term cruising (about 0.5 to 1 hour), requiring the total weight of thermal protection structures and load-bearing cold structures to be limited to less than 30%. At the same time, the overall requirements for structural load, structural life, anti-oxidation ability, vibration resistance and thermal protection effect are stringent. The overall goal is difficult to achieve, and new thermal design technologies must be developed. At the same time, in order to ensure repeated inspection and maintenance of airborne equipment and adaptability to wide-range environments, equipment cabins generally use non-sealed designs. The changes in internal and external pressure differences under wide-range flight and variable working conditions bring complex comprehensive thermal effects to the cabin environment. The factors affecting thermal design are many and complex. For the comprehensive thermal effect problems faced by its cabin design, an efficient thermal design process and simulation method have not yet been formed.
[0063] Hypersonic aircraft are affected by aerodynamic heat, propulsion system heat, and equipment heat. There are many types of heat sources, complex heat exchange forms, and different forms of heat and characteristics in each part. They mainly include external heat sources and internal heat sources. External heat sources include heat generated by aerodynamic heating, radiation heating, and leakage of the fuselage structure. Internal heat sources mainly come from electronic equipment such as radars and computers on board, mechanical equipment such as generators and steering gears, and heat generated by the propulsion system. As the part with the most influencing factors on the onboard heat source and the most obvious coupling characteristics of thermal sealing and thermal management, the thermal environment of the typical equipment compartment of hypersonic aircraft is difficult to solve through the cabin design concept based on traditional one-way serial.
[0064] Low Mach number aircraft do not need to adopt thermal protection design, and the fuselage skin is in a constant temperature and hot state for a long time. It is reasonable and feasible to adopt steady-state design based on severe state points in the traditional design process. However, as the Mach number of hypersonic aircraft increases, the appearance of thermal insulation will cause the structural temperature to continue to change during the entire flight process. If the traditional steady-state boundary design is still used, the design margin will be over-considered, which is very likely to lead to the non-closure of the technical solution.
[0065] In addition, since the total temperature of the incoming air is low for low Mach number aircraft, if there is gas backflow, the low-temperature air will enter the cabin, which will only have a positive impact on the cabin thermal environment. Therefore, the equipment cabin is often designed to be open, and no additional pressure requirements are made. As for the cabin of a hypersonic aircraft, as analyzed in the previous article, reasonable control of its pressure will significantly improve the thermal environment in the cabin, and its demand for thermal sealing design is much higher than that of a low Mach number aircraft.
[0066] The traditional design process is based on the idea of one-way serial and professional decoupling design to design the thermal seal thermal management scheme of the cabin. The traditional design process can be divided into four parts: aerodynamic thermal calculation, thermal protection and thermal seal design, thermal management design, and performance evaluation. This process has the following main problems.
[0067] Problem 1: Decoupling design of each discipline leads to low simulation accuracy
[0068] In the traditional design process, each discipline conducts decoupled design separately, and there are a lot of simple idealized processing in simulation, which leads to low accuracy. Taking thermal protection calculation as an example, the gas temperature and flow conditions in the cabin cannot be determined during calculation, so the precise boundary conditions of the cabin inner wall cannot be set. Usually, the inner wall is set as an adiabatic boundary, which is quite different from the heat transfer process in real scenes.
[0069] Problem 2: Serial design, low efficiency
[0070] Traditional cabin design has a clear professional process, which is to first perform aerodynamic thermal calculations, then complete thermal protection and thermal sealing calculations, and finally carry out thermal management design. Each part needs to use the output results of the previous process as the boundary, and specific work cannot be carried out before the previous process is completed. Although cabin thermal designers will divide the work according to their profession, usually only one professional will be involved in the work at the same time, while other professionals are in a waiting state, resulting in low design efficiency.
[0071] Problem 3: Initial design relies on experience
[0072] The work in each discipline can be summarized as two parts: scheme design and simulation calculation. When designing a scheme, there are no relevant references, instruction manuals, etc., especially when designing the initial scheme, there are no simulation calculation results of the previous round of schemes, and the initial scheme design can only be carried out based on experience. If there is insufficient experience, the initial scheme and the final scheme will deviate greatly, which will increase the number of iterations and thus increase the time required for cabin thermal seal thermal management design.
[0073] Problem 4: Repeated iterations are required
[0074] As mentioned in question 3, the initial schemes are mostly designed based on experience, which inevitably requires multiple rounds of iterative optimization. When returning to iteration, since there is no mechanism for influencing relevant parameters, each discipline can only make qualitative improvements based on the original scheme, which greatly increases the number of iterations. In addition, each iteration requires three-dimensional simulation calculations for the new scheme, which consumes a lot of time.
[0075] Problem 5: Evaluation is only done at the end of the process
[0076] The evaluation process is only carried out after a round of iterations is completed and all data is obtained, in order to judge the pros and cons of the scheme and whether the process is completed. Each iterative calculation takes a lot of energy and time from the designers. If the evaluation fails, the data results of this iteration become the process quantity in the cabin thermal design and can only provide a reference for the subsequent optimization of the scheme. A lot of time is wasted on the scheme calculation in the iterative process. If there is a fast evaluation method, it can greatly speed up the pace of cabin thermal comprehensive design.
[0077] Based on the above problems, the embodiment of the present application proposes an integrated design method for cabin thermal sealing and thermal management. For problem 1, a multi-discipline coupling design method is adopted to solve it. However, directly performing the coupled design of thermal seal thermal management will bring difficulties to the simulation calculation, such as cross-scale modeling of cabin-gap, multi-physics field coupling of thermal deformation of sealing structure and gas flow, and cross-time scale, which greatly increases the difficulty and time of simulation. Therefore, based on the starting point of multi-discipline coupling design without excessively increasing the difficulty of simulation, an integrated design method is proposed, which uses a one-dimensional model to couple the design and iterative optimization of the thermal seal thermal management solution, and then uses three-dimensional simulation for fine verification; the interface influencing factors between multiple disciplines in the design are coupled, which solves the problem of using simple idealized boundaries when designing separately for each discipline.
[0078] For problem 2, a coupled design method was adopted. Through repeated iterative design and optimization of a one-dimensional coupling model, a cabin thermal design scheme was formed, and then three-dimensional simulation was used for detailed verification. In this process, all disciplines participated in the design most of the time, which solved the problem of inefficiency caused by long waiting times for various disciplines in the traditional process.
[0079] For questions 3 and 4, the one-dimensional coupling design model has the characteristics of fast design calculation, and the time for one round of iterative design is much shorter than the traditional design process. The quality of the initial solution will only increase the rapid iteration process a few times, and will no longer have a great impact on the overall design time, solving the problem of the dependence of the scheme design on experience. In addition, a method of adding a parameter optimization function module to the one-dimensional coupling design model is proposed to solve the problem of a large number of iterations. Through core parameter optimization research, sensitivity analysis and other means, a key parameter group is established, and the mathematical relationship between the parameters is further established. Based on this, optimization suggestions for the scheme design parameters are proposed after the evaluation process, which can effectively reduce the number of scheme iterations.
[0080] In response to question 5, an efficiency and compensation evaluation module is added to the one-dimensional design for rapid evaluation. At the same time, based on the fast calculation characteristics of the one-dimensional model and the parameter optimization module, the speed of the cabin thermal design integration process is greatly accelerated.
[0081] Figure 1 A schematic flow chart of a cabin thermal sealing and thermal management integrated design method provided in an embodiment of the present application. The cabin thermal sealing and thermal management integrated design method includes:
[0082] 100. Apply boundary constraints to the initial input conditions of the cabin to obtain boundary conditions.
[0083] Optionally, the initial input conditions include: flight profile, cabin geometry model, aerodynamic heat, equipment heat, cabin pressure requirements, cabin temperature requirements, internal flow inlet conditions, and internal flow outlet conditions; specifically, the initial input conditions are confirmed to ensure the accuracy and efficiency of generating the integrated design scheme of cabin thermal sealing and thermal management.
[0084] Optionally, in addition to the above-mentioned boundary conditions, the traditional decoupled design process also has inputs and outputs between thermal sealing and thermal management, which serve as boundaries between them. In the integrated design process of the embodiment of the present application, thermal sealing and thermal management are coupled by design, and the data transfer between them is no longer a constraint boundary in the design.
[0085] Based on boundary conditions, the thermal sealing module and the thermal management module are coupled through one-dimensional design tools to construct an integrated design scheme for cabin thermal sealing and thermal management.
[0086] For details, please refer to Figure 2 , the heat sealing module and the thermal management module are coupled through the boundary loading module, the heat sealing thermal management parameter matching module, the heat sealing thermal management scheme design module, the flow heat transfer calculation module, the efficiency and compensation evaluation module, and the scheme output module; among them, by coupling the heat sealing module and the thermal management module, the integrated design scheme of cabin thermal sealing and thermal management is realized, the simulation accuracy is improved, and there is no need for repeated iterations.
[0087] Optionally, a one-dimensional design tool can be used to couple the cabin thermal sealing and thermal management. The one-dimensional design tool can reduce the complex cabin thermal comprehensive design problem to one dimension through methods such as averaging and reasonable partitioning. While ensuring a certain calculation accuracy, it can quickly couple the thermal sealing and thermal management solutions. The efficiency and compensation evaluation module can quickly evaluate the design solution and optimize the solution parameters through the parameter optimization module.
[0088] It is understandable that the one-dimensional design tool is mainly used for the preliminary design of thermal sealing thermal management solutions. Through its rapid loading, calculation and evaluation function optimization, the preliminary plan for the comprehensive thermal design of the cabin is obtained, and then the plan is verified using three-dimensional precise calculations to complete the final design.
[0089] More specifically, based on boundary conditions, the thermal sealing module and the thermal management module are coupled through a one-dimensional design tool to construct an integrated design solution for cabin thermal sealing and thermal management, including:
[0090] 210. Convert the three-dimensional boundary condition data into one-dimensional boundary condition data through the boundary loading module.

[0095] Specifically, each boundary data and boundary condition is loaded into the one-dimensional design tool through the boundary loading module to facilitate the construction of subsequent design solutions.
[0096] 220. Provide basic physical property parameters based on the heat sealing thermal management parameter matching module.
[0097] Optionally, the heat seal thermal management parameter matching module includes a heat seal characteristic database, a heat protection material physical property database and a cooling fluid database; these databases contain a large number of physical property parameters of heat seal structures, heat protection materials and cooling fluids, such as density, heat capacity, thermal conductivity, etc. The database module provides basic physical property parameters for the calculation of one-dimensional design tools and provides a reference basis for the design of heat seal thermal management solutions.
[0098] 230. Based on the boundary conditions, the initial design scheme is designed through the heat seal thermal management scheme design module combined with the influencing mechanism of various parameters.
[0099] Optionally, the initial design of the heat seal thermal management solution can be performed through the heat seal thermal management solution design module. During the initial design, the initial solution is designed based on the boundary conditions, based on experience and combined with the influencing mechanism of each parameter, and then the solution is optimized and improved through the one-dimensional design tool; specifically, based on the fast calculation, evaluation and optimization characteristics of the one-dimensional design tool, the quality of the initial solution no longer has too much impact on the iteration rounds and calculation time, which greatly eliminates the dependence of the design process on experience factors.
[0100] 240. The various modules of thermal sealing and thermal management are coupled through the flow heat transfer calculation module.
[0101] The optional heat transfer calculation module is the core calculation part of the one-dimensional design tool, which mainly includes the heat seal interface module, the cabin flow module, the cabin radiation heat transfer module and the electronic equipment heat source module. The heat transfer calculation module couples some parameters between the modules to complete the coupling solution of heat seal and thermal management, and improve the simulation accuracy and efficiency.

The heat generated by the electronic equipment is the main heat source inside the cabin. At the same time, the layout of the equipment will affect the flow in the cabin, so the electronic equipment heat source module needs to be added to the coupling calculation.
[0106] As mentioned above, the four modules of the flow heat transfer calculation module are coupled to complete the cabin flow heat transfer calculation, and the relevant data required for the evaluation of heat sink utilization, leakage, etc. can be obtained.

[0113] As mentioned above, the embodiment of the present application utilizes a one-dimensional design tool to perform coupled design of cabin thermal sealing and thermal management. The one-dimensional design tool reduces the complex cabin thermal comprehensive design problem to one dimension through methods such as averaging and reasonable partitioning. While ensuring a certain calculation accuracy, it can quickly perform coupled design of thermal sealing and thermal management solutions.
[0114] 300. Input the integrated design scheme of cabin thermal sealing and thermal management into the three-dimensional model for verification.
[0115] Specifically, according to the thermal sealing design scheme of the integrated design scheme of cabin thermal sealing and thermal management, the cabin structure wall temperature and the heat and mass transfer of the sealing structure are calculated to obtain the first data in the cabin; wherein the first data includes: leakage amount, wall temperature, and cabin temperature.
[0116] Based on the simulation boundary of the thermal management data, the second data in the cabin is calculated according to the thermal management design scheme of the cabin thermal sealing and thermal management integrated design scheme; wherein the second data includes flow heat transfer, mass compensation, and heat sink utilization.
[0117] It is determined whether the cabin temperature is within the set cabin temperature range. If so, the three-dimensional model is verified. If not, feedback is given to the one-dimensional design tool to instruct the one-dimensional design tool to optimize parameters.
[0118] Among them, the integrated design scheme of cabin thermal sealing and thermal management was subjected to three-dimensional inspection to optimize the design scheme and improve simulation accuracy.
[0119] As described above, the embodiment of the present application imposes boundary constraints on the initial input conditions of the cabin to obtain boundary conditions; based on the boundary conditions, the thermal sealing module and the thermal management module are coupled through a one-dimensional design tool to construct an integrated design scheme for cabin thermal sealing and thermal management; the integrated design scheme for cabin thermal sealing and thermal management is input into the three-dimensional model for verification; the interface influencing factors between multiple modules in the design are coupled, which solves the problem of using simple idealized boundaries when designing separate modules. Each module participates in the design most of the time, which solves the problem of high structural weight cost and low efficiency caused by modules being in a waiting state for a long time in the traditional process.
[0120] For example, the preliminary solution formed by the one-dimensional design tool is loaded into the three-dimensional model for simulation calculation. The process of three-dimensional simulation is as follows: Figure 2 As shown in the figure, the cabin structure wall temperature and the heat and mass transfer of the sealing structure are calculated based on the preliminary scheme of thermal protection / thermal sealing, and the leakage, wall temperature and other data are obtained. These data are used as the simulation boundary of thermal management, and the flow heat transfer in the cabin is calculated according to the preliminary design scheme of thermal management. The three-dimensional simulation calculation is completed to obtain the relevant data required for the evaluation of heat sink utilization, leakage, etc.
[0121] Specifically, boundary constraints are imposed on the initial input conditions (flight profile, cabin geometry model, aerodynamic heat, equipment heat, cabin temperature requirements, cabin pressure requirements, internal flow inlet conditions, and internal flow outlet conditions); the one-dimensional design tool is coupled to the heat seal thermal management module, and is processed in sequence through the boundary loading module, heat seal thermal management parameter matching module, heat seal thermal management scheme design module, flow heat transfer calculation module, and efficiency and compensation evaluation module to determine whether the cabin heat seal thermal management design scheme meets the efficiency, leakage and compensation requirements. If so, the scheme is output (including deformation, cabin pressure distribution, heat seal parameters, leakage characteristics, cabin temperature distribution, thermal management parameters and other data); if not, the parameter optimization module is used to optimize the parameters and perform three-dimensional fine verification of the design scheme.
[0122] Specifically, the design scheme is verified in three dimensions: the model corresponding to the thermal protection and thermal sealing scheme is divided into finite element networks, and the structural simulation and solution of the divided finite element networks are carried out through the aerodynamic thermal loading tool provided by the aerodynamic thermal data template to obtain the time-varying temperature field, deformation and other data of the whole machine. The time-varying temperature field of the whole machine is processed through the structural temperature loading tool provided by the structural temperature template, and the deformation is processed through the heat leakage model; the model corresponding to the thermal management scheme is divided into thermal management networks, and the thermal management simulation and solution are carried out based on the processed time-varying temperature field and deformation of the whole machine to obtain parameters such as cabin temperature distribution, deformation, cabin pressure distribution and leakage characteristics, and to judge whether the cabin temperature distribution meets the requirements. If so, the three-dimensional verification is passed. If not, the model is corrected through the parameter optimization module.
[0123] The thermal sealing / thermal management scheme of the embodiment of the present application is calculated by a one-dimensional design tool based on the multi-disciplinary coupling of thermal sealing and thermal management. The three-dimensional simulation calculation is carried out on the basis of the preliminary scheme. Taking the thermal protection calculation of the cabin wall temperature as an example, the integrated process uses the one-dimensional cabin average temperature, flow heat transfer and other data as the boundary conditions of the inner wall during calculation, while the traditional process usually idealizes the inner wall as an adiabatic condition. The rationality and accuracy of the preliminary scheme are evaluated by the data obtained through three-dimensional calculations, and it is judged whether further optimization design needs to be carried out through a one-dimensional design tool: whether the cabin average temperature, pressure and other conditions meet the working conditions of electronic equipment throughout the process; whether the evaluation data such as heat sink utilization, leakage rate, mass compensation and the calculated data of the one-dimensional design tool meet a certain accuracy and are better values.
