Description

Technical Field

[0001] This application relates to the field of air conditioning monitoring technology, and in particular to a small aircraft air conditioning load monitoring platform. Background Technology

[0002] Small aircraft, due to their flexibility and wide range of applications, often need to perform missions under various complex weather conditions and flight attitudes. The onboard air conditioning system, as a key component ensuring cabin comfort and the normal operating temperature of some electronic devices, is crucial to their operational stability. However, compared to large commercial aircraft, small aircraft have relatively lighter fuselage structures, resulting in more significant and frequent attitude changes (roll, pitch) and fuselage vibrations during climbs, dives, turns, and encounters with turbulence.

[0003] Currently, air conditioning systems in small aircraft are typically rigidly mounted directly to the fuselage structure or using simple brackets. This traditional mounting method has the following significant drawbacks: When the aircraft's attitude changes, the air conditioning unit tilts accordingly. Its internal components, such as the compressor, evaporator, and condenser, as well as the refrigerant circulation pipeline, are not designed for tilted operation. Attitude changes can lead to uneven distribution of refrigerant in the pipeline and heat exchanger, difficulty in lubricating oil return, and abnormal fluctuations in compressor load. This can result in a significant decrease in cooling efficiency, unstable system pressure, and long-term operation may also accelerate component wear and even cause malfunctions.

[0004] Existing installation schemes lack real-time, in-situ, and comprehensive monitoring of the air conditioning system's operating status. Maintenance personnel can usually only conduct rough checks using external instruments during scheduled maintenance or rely on the crew's subjective feelings to report abnormalities. It is difficult to obtain objective and accurate system operating parameters (such as outlet pressure, temperature, and flow rate) during flight. This leads to delayed fault warnings, inaccurate performance assessments, and hinders the implementation of predictive maintenance, increasing operational risks and maintenance costs.

[0005] To address the aforementioned problems, this invention proposes a small aircraft air conditioning load monitoring platform, which can overcome the shortcomings of existing air conditioning systems such as sensitivity to flight attitude, weak vibration resistance, and unknown status, thereby comprehensively improving the working stability, reliability, and maintainability of small aircraft air conditioning systems under different flight conditions. Summary of the Invention

[0006] To address the problems existing in the background art, the present invention proposes a small aircraft air conditioning load monitoring platform.

[0007] The technical solution adopted in this application for a small aircraft air conditioning load monitoring platform is as follows: A small aircraft air conditioning load monitoring platform includes: a load platform, a multi-degree-of-freedom platform, a monitoring platform, and an air conditioning unit. The load platform has a rectangular structure and is fixedly installed on the aircraft fuselage. A multi-degree-of-freedom platform is fixedly installed on the upper part of the load platform, and a monitoring platform is fixedly installed on the upper part of the multi-degree-of-freedom platform. The multi-degree-of-freedom platform can adjust the levelness of the monitoring platform according to the flight attitude of the aircraft. The air conditioning unit is fixedly installed on the upper part of the monitoring platform, and the monitoring platform can monitor the levelness of the air conditioning unit as well as the output pressure, temperature, and flow rate.

[0008] Furthermore, buffer components are installed around the bottom of the support platform to cushion the vibrations generated by the machine body.

[0009] Furthermore, the buffer component includes a fixed frame, a buffer frame, and a buffer rubber. The bearing platform has mounting holes evenly distributed around its perimeter. A fixed frame is fixedly installed in the mounting holes. The fixed frame has a Z-shaped structure. A buffer frame is movably installed at the lower end of the fixed frame. A buffer rubber is installed between the buffer frame and the fixed frame. The buffer rubber is made of a highly elastic material.

[0010] Furthermore, the multi-degree-of-freedom platform includes an adjustment unit, a supply chamber, and a support plate. The adjustment units are evenly installed on the upper part of the support platform, and the supply chamber is fixedly installed in the middle of the upper part of the support platform. The supply chamber is used to supply hydraulic oil to the adjustment units. The support plate is installed between the upper ends of the adjustment units, and the upper end of the support plate is fixedly connected to the monitoring platform.

[0011] Furthermore, the adjustment unit includes a hydraulic cylinder, a universal mounting base, a control valve, and a connecting conduit. The upper and lower ends of the hydraulic cylinder are respectively connected to the bearing platform and the support plate through the universal mounting base. A control valve is fixedly installed on the outside of the supply compartment, and the control valve is connected to the lower end of the hydraulic cylinder through the connecting conduit.

[0012] Furthermore, the monitoring platform includes a mounting plate, a locking bracket, and a monitoring unit. The mounting plate has a rectangular structure and is fixedly mounted on the upper end of the support plate. The air conditioner body is fixedly mounted on the middle of the upper end of the mounting plate via the locking bracket. A monitoring unit is fixedly mounted on the front side of the upper end of the mounting plate, and the monitoring unit is connected to the output end of the air conditioner body.

[0013] Furthermore, the locking frame has a frame-shaped structure, and a rubber pad is installed on the inner wall of the locking frame.

[0014] Furthermore, the monitoring unit includes a monitoring frame, a connecting flange, a pressure sensor, a temperature sensor, and a flow sensor. The monitoring frame has a rectangular hollow structure. The lower end of the monitoring frame is fixedly mounted on the upper end of the mounting plate by a bracket. Connecting flanges are symmetrically installed at the front and rear ends of the monitoring frame. The pressure sensor, temperature sensor, and flow sensor are sequentially installed on the outer surface of the monitoring frame. The pressure sensor, temperature sensor, and flow sensor are connected to the interior of the monitoring frame.

[0015] Furthermore, tilt sensors are evenly installed around the upper edge of the mounting plate.

[0016] Beneficial effects Compared with the prior art, the present invention provides a small aircraft air conditioning load monitoring platform, which has the following beneficial effects: 1. In this invention, through the active and real-time attitude leveling function of the multi-degree-of-freedom platform, the air conditioning unit can always be kept in the horizontal attitude required by the design, regardless of the aircraft's maneuvering flight state such as climb, dive, or turn. This solves the core problems of uneven refrigerant distribution and compressor load fluctuation caused by fuselage tilt under the traditional rigid installation method, so that the air conditioning system always operates in the optimal attitude, ensuring stable cooling efficiency and system pressure.

[0017] 2. In this invention, the monitoring unit integrates pressure sensors, temperature sensors, and flow sensors onto a monitoring frame connected in series with the air conditioning output pipeline, ensuring the synchronization and positional consistency of all sensor measurement data. It can accurately and in real time acquire the core parameters (pressure, temperature, and flow) reflecting the air conditioning performance, providing unprecedented data support for in-flight status monitoring, early fault warning, and accurate performance evaluation during ground maintenance, realizing the transformation from "post-maintenance" to "predictive maintenance".

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-6 The present invention provides a small aircraft air conditioning load monitoring platform, comprising: a load platform 1, a multi-degree-of-freedom platform 2, a monitoring platform 3, and an air conditioning body 4. The load platform 1 has a rectangular structure and is fixedly installed on the aircraft fuselage. The multi-degree-of-freedom platform 2 is fixedly installed on the upper end of the load platform 1, and the monitoring platform 3 is fixedly installed on the upper end of the multi-degree-of-freedom platform 2. The multi-degree-of-freedom platform 2 can adjust the levelness of the monitoring platform 3 according to the flight attitude of the aircraft. The air conditioning body 4 is fixedly installed on the upper end of the monitoring platform 3, and the monitoring platform 3 can monitor the levelness of the air conditioning body 4 as well as the output pressure, temperature, and flow rate.

[0028] In the above technical solution, when the aircraft is climbing, diving or circling, the fuselage will tilt, which will affect the flow and distribution of refrigerant inside the air conditioning unit 4. The multi-degree-of-freedom platform 2 can adjust the tilt of the monitoring platform 3 and the air conditioning unit 4 according to the flight attitude of the aircraft, so that the air conditioning unit 4 is always in a horizontal state. The monitoring platform 3 can also monitor the pressure, temperature and flow rate output by the air conditioning unit 4, thereby ensuring that the air conditioning unit 4 can be in a normal cooling state.

[0029] See Figures 1-3 As shown, as a preferred technical solution in this embodiment, a buffer 11 is also installed around the bottom of the bearing platform 1, which can buffer the vibration generated by the machine body.

[0030] See 1- Figure 3As shown, as a preferred technical solution of this embodiment, the buffer 11 includes a fixed frame 111, a buffer frame 112, and a buffer rubber 113. The bearing platform 1 has mounting holes evenly distributed around its perimeter. The fixed frame 111 is fixedly installed in the mounting holes. The fixed frame 111 has a Z-shaped structure. The buffer frame 112 is movably arranged at the lower end of the fixed frame 111. The buffer rubber 113 is installed between the buffer frame 112 and the fixed frame 111. The buffer rubber 113 is made of a highly elastic material.

[0031] In the above technical solution, the bearing platform 1 is fixed to the body by the buffer 11. When the body vibrates, the buffer frame 112 absorbs the vibration generated by the body through the buffer rubber 113, so as to prevent the vibration from being transmitted to the air conditioner body 4 and to prevent the vibration from affecting the cooling effect of the air conditioner.

[0032] See Figure 4 As shown, as a preferred technical solution in this embodiment, the multi-degree-of-freedom platform 2 includes an adjustment unit 21, a supply chamber 22, and a support plate 23. The adjustment units 21 are evenly installed on the upper end of the bearing platform 1, and the supply chamber 22 is fixedly installed in the middle of the upper end of the bearing platform 1. The supply chamber 22 is used to supply hydraulic oil to the adjustment units 21. The support plate 23 is installed between the upper ends of the adjustment units 21, and the upper end of the support plate 23 is fixedly connected to the monitoring platform 3.

[0033] See Figure 4 As shown, in this preferred embodiment, the adjustment unit 21 includes a hydraulic cylinder 211, a universal mounting base 212, a control valve 213, and a connecting conduit 214. The upper and lower ends of the hydraulic cylinder 211 are respectively connected to the bearing platform 1 and the support plate 23 through the universal mounting base 212. The control valve 213 is fixedly installed on the outside of the supply chamber 22, and the control valve 213 is connected to the lower end of the hydraulic cylinder 211 through the connecting conduit 214.

[0034] In the above technical solution, the support platform 1 is mounted on the body as a fixed base, the supply compartment 22 serves as the power source of the system, stores hydraulic oil and is equipped with a pump set to provide stable and controllable hydraulic power for the entire adjustment system; the support plate 23 serves as the output platform and is directly rigidly connected to the monitoring platform 3, and its posture represents the posture of the air conditioner body; the adjustment unit 21 is the actuator of the system, which is evenly distributed on the support platform 1, and its upper end is hinged to the support plate 23 through the universal mounting seat 212, which together support and drive the support plate.

[0035] All the hydraulic cylinders 211 of the regulating unit 21 are connected to the control valve 213 group outside the supply chamber 22 through the connecting conduit 214. The control valve 213 group receives real-time attitude signals (such as tilt angle and angular velocity) sent from the monitoring platform 3 or the aircraft attitude. Based on these signals, the controller quickly calculates and outputs instructions to accurately control the opening and closing and flow of each control valve 213, thereby injecting or discharging hydraulic oil of different flow rates into or out of the corresponding hydraulic cylinder 211.

[0036] When the aircraft's attitude changes, such as when it rolls to the right, the support platform 1 fixed to the fuselage tilts accordingly. At this time, the sensor immediately detects this change, and the control system responds quickly by issuing a command: the control valve 213 of the right adjustment unit 21 actuates, driving its hydraulic cylinder 211 to retract as needed; at the same time, the left adjustment unit 21 drives its hydraulic cylinder 211 to extend synchronously. This coordinated extension and retraction action, transmitted through the support plate 23, cancels the tilt angle of the fuselage in a very short time, so that the support plate 23 and the monitoring platform 3 and the air conditioning unit 4 on it are restored to and maintained in a horizontal state.

[0037] See Figures 5-6 As shown, as a preferred technical solution in this embodiment, the monitoring platform 3 includes a mounting plate 31, a locking frame 32, and a monitoring unit 33. The mounting plate 31 has a rectangular structure and is fixedly mounted on the upper end of the support plate 23. The air conditioner body 4 is fixedly mounted on the middle of the upper end of the mounting plate 31 through the locking frame 32. The monitoring unit 33 is fixedly mounted on the front side of the upper end of the mounting plate 31 and is connected to the output end of the air conditioner body 4.

[0038] See Figures 5-6 As shown, as a preferred technical solution in this embodiment, the locking frame 32 has a frame-shaped structure, and a rubber pad is installed on the inner wall of the locking frame 32.

[0039] In the above technical solution, the frame-shaped locking bracket 32 ​​hugs the air conditioner body from all sides, providing uniform restraint and preventing it from shifting or loosening under any flight maneuver. The rubber pads laid on the inner wall of the locking bracket 32 ​​play a key role in vibration isolation and buffering. They can further absorb and attenuate the medium and high frequency residual vibrations transmitted through the mounting plate 31 (these vibrations may not be completely filtered by the bottom buffer 11). At the same time, as a soft interface, it avoids hard friction and stress concentration between the metal components and the air conditioner casing due to thermal expansion and contraction or deformation under force. Its effect is to protect the outer casing structure of the air conditioner body to the greatest extent while ensuring tightness, and to provide a second layer of vibration protection for its internal precision components.

[0040] See Figures 5-6As shown in the preferred technical solution of this embodiment, the monitoring unit 33 includes a monitoring frame 331, a connecting flange 332, a pressure sensor 333, a temperature sensor 334, and a flow sensor 335. The monitoring frame 331 has a rectangular hollow structure. The lower end of the monitoring frame 331 is fixedly mounted on the upper end of the mounting plate 31 by a bracket. The connecting flanges 332 are symmetrically installed at the front and rear ends of the monitoring frame 331. The pressure sensor 333, the temperature sensor 334, and the flow sensor 335 are sequentially installed on the outer surface of the monitoring frame 331. The pressure sensor 333, the temperature sensor 334, and the flow sensor 335 are connected to the interior of the monitoring frame 331.

[0041] In the above technical solution, the monitoring unit 33 is the core of the platform's data sensing. The monitoring frame 331 is a rectangular hollow pipe structure, connected in series to the output pipe of the air conditioner body 4 through the connecting flanges 332 at both ends, ensuring that the refrigerant airflow output by the air conditioner must flow through the interior of the monitoring frame 331. The pressure sensor 333 is used to monitor the output pressure of the refrigerant in real time. Pressure is a key indicator reflecting the compressor's working status, system blockage, or leakage. The temperature sensor 334 is used to accurately measure the temperature of the output airflow, which is a direct basis for evaluating the air conditioner's cooling efficiency and determining whether the heat exchanger is working properly. The flow sensor 335 directly reflects the air delivery capacity of the air conditioning system; abnormal flow may indicate fan failure, filter blockage, or pipe problems.

[0042] See Figures 5-6 As shown, as a preferred technical solution in this embodiment, tilt sensors 311 are also evenly installed around the upper perimeter of the mounting plate 31.

[0043] In the above technical solution, the tilt sensor 311 is a microelectromechanical system (MEMS) or an electrolyte type. The tilt sensor 311 continuously measures the absolute tilt angle of the mounting plate 31 relative to the horizontal plane in the roll and pitch axes. Its measurement data is transmitted to the multi-degree-of-freedom platform 2 in real time. The air conditioner body 4 is accurately adjusted by the extension and retraction of the adjustment unit 21 of the multi-degree-of-freedom platform 2.

[0044] Based on the above structure, the small aircraft air conditioning load monitoring platform provided by the present invention operates according to the following steps: S1: System power-on initialization and baseline establishment When the aircraft power supply system is started, multiple tilt sensors 311 on the mounting plate 31 of the monitoring platform 3 are powered on and start working. The control system reads and records the initial readings of each tilt sensor at this time and sets them as the "horizontal reference zero point". At the same time, the hydraulic pump in the supply compartment 22 of the multi-degree-of-freedom platform 2 starts to establish a stable pressure for the entire hydraulic leveling system. The hydraulic cylinders 211 of all adjustment units 21 are in standby state. The pressure sensor 333, temperature sensor 334 and flow sensor 335 in the monitoring unit 33 also begin self-checking and prepare to collect data.

[0045] S2: Passive vibration isolation and dynamic load buffering During the takeoff, takeoff, flight, or landing phases of an aircraft, vibrations and impacts of various frequencies generated by the fuselage are first passively attenuated by the buffer 11. Specifically, the vibration energy is transmitted to the buffer rubber 113 through the buffer frame 112, which absorbs and dissipates most of the kinetic energy by utilizing its high elastic deformation, significantly reducing the vibration intensity transmitted to the bearing platform 1 and its components. This provides a preliminary stable installation foundation for the air conditioning unit 4 and protects its internal mechanical components from high-frequency vibration damage.

[0046] S3: Active Sensing and Dynamic Attitude Leveling During flight, once the fuselage attitude changes (such as climbing, diving, or turning), the tilt sensor 311 monitors the tilt angle (roll and pitch) of the mounting plate 31 in real time. This attitude deviation signal is immediately sent to the control system of the multi-degree-of-freedom platform 2. The controller quickly calculates and generates precise extension and retraction commands for the hydraulic cylinders 211 of each adjustment unit 21 according to a preset algorithm. The commands drive the control valve 213 to act, injecting or discharging hydraulic oil of a specific flow rate from the supply chamber 22 into or out of the corresponding hydraulic cylinder through the connecting conduit 214. With the cooperation of the universal mounting base 212, each hydraulic cylinder extends and retracts in coordination, jointly pushing the support plate 23 and the entire monitoring platform 3 and air conditioning body 4 on it to move in the opposite direction, thereby offsetting the fuselage tilt in a very short time and restoring the air conditioning body to a horizontal working attitude.

[0047] S4: Real-time monitoring of air conditioner operating status Throughout the flight, regardless of changes in aircraft attitude, the air conditioning unit 4 remains stably level through real-time leveling in step S3. The refrigerant airflow output by the unit passes through the monitoring frame 331 of the monitoring unit 33. The pressure sensor 333, temperature sensor 334, and flow sensor 335 integrated on the monitoring frame synchronously and in situ collect the three key performance parameters of the airflow pressure, temperature, and flow rate. The monitoring data is transmitted in real time to the aircraft's monitoring system or recording device, providing direct and reliable data for assessing the current working efficiency of the air conditioning system and determining whether its working status is normal.

[0048] S5: Closed-loop feedback and continuous stability assurance The tilt sensor 311, acting as a feedback element, continuously feeds back the actual horizontal state of the mounting plate 31 to the controller. The controller then directs the multi-degree-of-freedom platform 2 to perform corrective actions. This closed loop ensures high precision and dynamic tracking during the leveling process. Meanwhile, the air conditioning performance data collected by the monitoring unit 33, the locking frame 32, and its rubber pads continuously play a secondary vibration isolation and safety fastening role during this process, preventing the air conditioning unit from making slight movements due to inertia or residual vibration. Through the cyclical operation of the above steps, the platform comprehensively ensures the continuous, stable, and efficient cooling of the small aircraft air conditioning system in complex flight environments from three aspects: physical vibration isolation, dynamic attitude compensation, and real-time performance monitoring.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
