Description

Summary of the invention

[0001] 1. Device composition (I) Wing car: The main component of this device, responsible for carrying the aircraft for takeoff and moving on the ground, with a designed maximum speed of 300KM / H, reaching the take-off speed of most passenger aircraft.

[0002] Main components and functions of wing cars 1. Car body: It is equipped with power battery, cockpit, control system, aircraft connection device on the top and main wheels on the bottom. It is the main part of the camel-borne aircraft.

[0003] 2. Wing: The shape is triangular, and the wing surface provides effective downforce for the vehicle body when driving at high speed. The wheels installed under the wing provide the wing car with a larger ground contact area and lateral width, thereby improving the stability when carrying an aircraft.

[0004] 3. Wheels: Three pairs of six wheels are symmetrically distributed under the vehicle body, and one pair of two wheels are symmetrically distributed under the wings. Each wheel is connected to a power battery and equipped with a high-horsepower motor to provide power for the entire device. The sum of the horsepower of all wheels is the boost horsepower when the aircraft takes off.

[0005] (ii) Connection device: It is used to stably connect the wing car to the aircraft. It is divided into the wing car part and the aircraft part. The wing car part is composed of the vehicle body connection device shown in the figure, which is connected to the aircraft part connection device (connected to the main frame structure of the aircraft and can be retracted into the belly of the aircraft during flight) by the purple electromagnetic adsorption surface. The limiter is set to prevent the wing car from falling off when the docking is decelerated. The limiter is lowered into the vehicle body in the accelerated take-off state. When the aircraft reaches the take-off speed, the electromagnetic adsorption device is powered off and the aircraft takes off naturally and separates from the wing car.

[0006] (III) Wing car aircraft docking device: It is located at the end of the runway and is of trench type. The wing car enters the trench and docks after the aircraft stops above the trench. After the docking is completed, the aircraft retracts its landing gear and the wing car carries the aircraft onto the ground from the trench ramp.

[0007] 2. Device operation mode: (I) Docking phase: After landing, the aircraft taxis to the end of the runway above the wing car aircraft docking device, completes docking with the wing car, the wing car raises the limiter, and the aircraft retracts the landing gear and shuts down the engine.

[0008] (II) On-site operation phase: The wing car carries the aircraft to the apron for refueling, replenishment, and passenger boarding. During this period, the wing car provides power to the aircraft through the on-board battery.

[0009] (III) Take-off phase: The wing car carries the aircraft onto the runway, the aircraft starts its engine, the wing car lowers the limiter and starts to sprint at full power. When the aircraft reaches the take-off speed and take-off engine thrust, the wing car disconnects the electromagnetic attraction with the aircraft, the aircraft takes off, and the wing car decelerates and drives into the docking device trench to charge.

[0010] 3. Device Revenue Estimation 1. Aircraft take-off phase: 1. Provide the aircraft with electromagnetic catapult-like thrust, which greatly reduces fuel consumption during takeoff and effectively increases the range with the same amount of fuel.

[0011] 2. Additional takeoff thrust can increase the maximum takeoff weight of the aircraft.

[0012] 3. Effectively shorten the runway length required for takeoff. Some airports can effectively use the marginal space to increase short takeoff runways and improve airport operation efficiency.

[0013] 4. During the take-off phase, the aircraft is in the state of retracting the landing gear, which effectively reduces wind resistance and reduces fuel consumption.

[0014] (II) On-site operation stage: 1. After the aircraft docks with the wing car, the engine can be shut down until the next takeoff to save fuel.

[0015] 2. The wing car provides power to the aircraft throughout the entire journey, replacing the function of the airport charging car.

[0016] 3. Completely replace the function of aircraft tractor.

[0017] 4. The turning radius of a wing-carrying aircraft is significantly reduced compared to the aircraft's own power state or the aircraft tractor's towing state. The aircraft can reverse at any time and even develop the function of turning on the spot, which significantly improves the aircraft's flexibility.

[0018] 5. If necessary, the aircraft can be directly carried by the wing truck through the highway for large-scale transfer without the need for additional aircraft towing vehicles.

[0019] 4. The development and application prospects of the device in canceling the landing gear of large UAVs: Large UAVs have a high degree of automation, low trial and error costs, and basically no casualties. Therefore, the landing operation of docking an aircraft with a wing car can be tested on large UAVs. That is, by developing a landing docking system, the wing car (smaller and more unmanned than the wing car docking passenger aircraft) and the large UAV have the same horizontal speed during the landing phase. The impact force caused by the vertical speed of the UAV's descent is within the tolerance range of the entire system, and the large UAV can accurately dock with the wing car at the moment of landing. If the development is successful, large UAVs do not need landing gear during takeoff and landing. They only need to install a docking device that is much lighter than the landing gear, thus realizing a landing gear-free aircraft, effectively improving the cruising radius, effective load and other parameter indicators of large UAVs.
