Description

Technical Field

[0001] The invention relates to the technical field of large-scale aviation equipment design and precision manufacturing industry, and in particular to a modular design structure of a large-scale load-carrying airship. Background Art

[0002] "Airship" is an aircraft that can stay in the air for a long time without power; it is widely used in military and civilian fields. With the opening of China's low-altitude airspace, "airship" has a wide range of applications with its unique functions and characteristics.

[0003] Large-scale load-carrying airships using traditional design and manufacturing methods face many technical, material, equipment, and manufacturing challenges. The existing largest airship, the Hindenburg, has a total lift of just over 200 tons and a net load of only 20 to 30 tons, which is difficult to meet people's special needs for larger load-carrying airships with loads of tens or hundreds of tons.

[0004] The patent number is 201580035652.1, and the patent name is "Multi-purpose airship and airship group". The airship shape and overall structure are a six-sided cube structure, which seriously violates the basic design principles of aircraft aerodynamics and structural mechanics. The design of the aircraft shape should adopt a "streamlined" design with less wind resistance, and the "cube shape" design is a shape structure with the largest wind resistance; the overall rigidity design is a cube, and the stress acting on the six faces will be transmitted to the junction of the two adjacent faces, causing the concentrated stress there to be large, seriously affecting the overall structural strength of the hull, and its load is relatively light. Summary of the invention

[0005] The present invention provides a large-scale load-carrying airship modular design structure, which solves the engineering manufacturing problem that the load of a single-hull load-carrying airship is too large (the geometric size is huge).

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a large-scale load-carrying airship modular design structure, the structure of the load-carrying airship includes an airship control module unit, a buoyancy module unit, a skeleton structure module unit, a load structure module unit, a power module unit, an unloading balance control module unit, and an auxiliary function module unit;

[0007] The airship control module unit is arranged in the cockpit and is used for the flight control of the airship and the control and management of each submodule;

[0008] The buoyancy module unit is composed of one or more buoyancy module units, and the total lift thereof is changed by changing the integrated number of the buoyancy module units; each buoyancy module unit is made of a rigid frame made of carbon fiber composite materials or high modulus lightweight materials, and multiple cabins are designed therein, and a lift airbag is arranged in each cabin, and the lift airbag is sewn and welded with a special fabric for polymer fiber airship capsule;

[0009] The skeleton structure module unit is arranged at the bottom of the buoyancy module unit and is designed as a rigid structure; it is used to load various module units;

[0010] The load structure module unit is used to carry cargo and is arranged at the bottom of the load-carrying airship. It is divided into a link hinge, a cargo container or a cargo platform according to the characteristics of the cargo and the requirements of the transportation conditions.

[0011] The power module unit provides power for the airship mission flight control. According to the instructions issued by the airship control module unit, the various power modules can be arbitrarily grouped and operated to achieve the control flight of the airship attitude. It is composed of power modules such as hybrid power and vector power, and the energy types used are fuel oil, gas, hydrogen energy, electric energy or nuclear energy.

[0012] The unloading balance control module unit is used to reduce or increase the total lift of the airship after unloading by "releasing or storing" the lift gas, thereby achieving balanced flight control of the airship after unloading;

[0013] The auxiliary function module unit is used for relevant data collection, analysis, early warning, fire protection, safety, lighting, communication, supply, etc. inside and outside the airship. It has the function of remote automatic weather forecasting, and can instantly forecast the meteorological information on the airship flight route to ensure the safety of the airship flight.

[0014] Furthermore, each buoyancy module unit is designed with a buoyancy module size and a module quantity according to the design load size. The lifting force of a single buoyancy module unit is in the range of tens to hundreds of tons, providing sufficient buoyancy for the airship.

[0015] Furthermore, the material of the skeleton structure module unit is carbon fiber composite material or high-strength lightweight material.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] 1) The present invention conducts modular design according to the design and functional requirements of the airship, decomposes the large-scale load-bearing airship into two or more independent hull lift systems, and decomposes the design functions of the airship into relatively independent structural modules, and uses the airship control module (computer system) to operate and manage each submodule unit system;

[0018] 2) The present invention can increase or decrease the total lift of the airship by increasing or decreasing the number of buoyancy modules according to different design requirements and functional requirements; the structural form and number of the load modules can be changed according to the characteristics and properties of the loaded cargo, such as: the transportation of large wind turbine blades, virgin forest logging, and the lifting of large objects can adopt the hinged mounting module form; the transportation of household cars can adopt the super-large platform module form; there is also a cargo box module form, etc.

[0019] 3) The increase or decrease in the number of submodule units and the change in the structural form of the present invention can change the technical parameters and design functions of the load-carrying airship without changing the design method of modular design and manufacturing.

[0020] 4) The buoyancy module of the present invention is designed as an olive-shaped streamlined structure with low wind resistance, and the frame is designed as a toroidal curved multi-cabin rigid structure. Various stresses are continuously decomposed and synthesized through the toroidal curved surface, so that the overall structural strength of the airship reaches the strongest state.

[0025] The invention discloses a large-scale load-carrying airship modular design structure, which is composed of one or more buoyancy modules (independent hulls); the total lift, load and other functions thereof are changed by changing the integrated number of buoyancy module units; and the design method of modular design and manufacturing does not need to be changed.

[0026] The present invention integrates one or more independent buoyancy modules into a giant load-carrying airship through "modular design"; each structural part, power part and flight control system of the airship all implement "modular design".

[0027] The large load-carrying airship is composed of an airship control module unit, a buoyancy module unit, a skeleton structure module unit, a load structure module unit, a power module unit, an unloading balance control module unit, and an auxiliary function module unit. Figure 1 shown.

[0030] Design requirements: It must have central computer, data photoelectric conversion system, data processing system, data real-time transmission system, data instruction operating system, power battery circuit management system, module control system, system control program system, etc. The above systems are all existing systems.

[0031] Functional requirements: It is the central command center of the airship flight, and its main function is to control and manage the flight of the airship and the systems of each submodule unit. The airship control module adopts advanced and mature optical transmission and electronic control technology to realize the digital transmission, calculation and status management of its branch control module units; the module program design does not need to rewrite the addition or reduction of its branch design modules, and the system will automatically close and open the relevant system caliber to realize the computer modular management of the system.

[0032] 2. Buoyancy module unit 2; It is a "rigid airship" without a power plant and flight control system.

[0033] Design requirements: The skeleton is a rigid structural material made of carbon fiber composite materials or other high modulus lightweight materials. Multiple cabins are designed in the rigid structure (keel). Each cabin has a lift airbag. The lift airbag is sewn and welded with special fabric for polymer fiber airship capsules. The appearance of the buoyancy module is an "olive-shaped" streamlined structure with less wind resistance.

[0034] Functional requirements: The entire large load-bearing airship is composed of one or more buoyancy module units. The size and number of the buoyancy modules are determined according to the design load size. The lift design of a single buoyancy module can reach tens of tons to hundreds of tons. Its function is to provide sufficient buoyancy (lift) for the airship according to the design requirements. The change of the buoyancy size, data collection and status management of the buoyancy module unit are controlled by the airship control module unit.

[0035] 3. Skeleton structure module unit 3:

[0036] Design requirements: The skeleton structure module unit is set at the bottom of the buoyancy module unit. The skeleton design is a toroidal curved multi-cabin rigid structure design. Various stresses are continuously decomposed and synthesized through the toroidal curved surface, so that the overall structural strength of the airship reaches the strongest state; it is used to load various module units. The material can be selected from carbon fiber composite materials with stable technical parameters, superior performance, and advanced workpiece preparation technology, or other high-strength lightweight materials to meet the design requirements of large size, high strength, high rigidity, and low density. The skeleton structure module unit can be designed according to the number of buoyancy hull modules. The design parameters of the load structure module depend on the design technical data of large-scale load-bearing airships. The molding process of carbon fiber composite materials has made a breakthrough. Scientific and advanced preparation processes such as 3D printing, cross-laying, carbon filament winding, high temperature curing, room temperature curing, high and low pressure injection molding, etc. have been widely used in aerospace, automobile manufacturing, construction engineering and other precision manufacturing industries.

[0037] Functional requirements: The skeleton structure module unit is a device-type load-bearing and rigid skeleton structure part of the large load-bearing airship of the present invention.

[0038] 4. Load structure module unit 4: used to carry cargo and arranged at the bottom of the load-carrying airship.

[0039] Technical requirements: According to the characteristics of the cargo and the requirements of transportation conditions, it can be designed as: connecting hinges, containers, cargo platforms and other structural design modules, which are composed of multiple sets of overhead cranes and containers, cargo platforms, mounting hinges and other devices.

[0040] Functional requirements: The load structure module unit is used for loading, unloading, stacking and transportation of the cargo. The operation and operation of this module should be completed on the ground.

[0041] 5. Power module unit 5: This module is composed of power modules such as hybrid power and vector power, and its energy types include fuel oil, natural gas, hydrogen energy, electric energy, nuclear energy and other power energies.

[0042] Design requirements: According to the functional requirements and load capacity of the airship, the total power of the airship, the number of power machines and the distribution of power equipment are designed; large-scale load-bearing airships have the characteristics of large volume and geometric dimensions, and the design adopts hybrid power and vector power systems. Each power system is an independent power module, using "hybrid power" and can be a hybrid configuration of fuel power, electric power, vector power, pneumatic power, etc.

[0043] Functional requirements: Provide power for the airship mission flight. According to the instructions issued by the airship control unit, the power modules can be grouped and operated arbitrarily (for example, the left and right power modules are grouped, that is, deceleration and closing the left power, or opening the right power and accelerating the right power to provide lateral torque, so that the airship can turn left, and vice versa; for example, the front and rear longitudinal power modules are grouped, vector power is turned on, and longitudinal torque is provided to achieve the longitudinal flight attitude balance of the airship, etc.), and the attitude of the airship can be controlled. The increase and decrease of power modules do not require rewriting the control program design method.

[0044] 6. Unloading balance control module unit 6 is an equipment module for reducing the huge lift of the airship or for balance control after one or more groups of loaded airships are unloaded.

[0045] Technical requirements: The design requirements of the post-unloading control module are composed of one or more independent unloading control modules. When a large-loaded airship is unloaded, the airship has tens or even hundreds of tons of lift that needs to be reduced and balanced. The unloading balance control module can reduce or increase the total lift of the airship by "releasing or storing" the lift gas when unloading or fully loaded, so as to achieve balanced flight of the airship after unloading. This is a design and manufacturing problem that traditional load-bearing airships have not been able to solve so far.

[0046] Functional requirements: Use this module to solve the problem of how to balance and control the huge lift of a loaded airship after unloading.

[0047] 7. Auxiliary function module unit 7:

[0048] Technical design requirements: meet the needs of airship internal and external data collection, analysis, early warning, fire protection, safety, lighting, communication, supply, etc. The module has the function of remote automatic weather forecasting, and can instantly forecast the meteorological information on the airship flight route to ensure the safety of the airship flight.
