Problems solved by technology

[0002] Now there are three main ways for the plane to take off: 1. The plane takes off after taxiing on the land runway: there is a problem that the plane needs to taxi for a long distance on the land runway
2. The aircraft uses the steam catapult to increase the initial speed of the aircraft to take off: there are problems such as steam catapults are difficult to manufacture, complex in manufacturing technology, difficult to operate, and large in energy consumption.
3. The aircraft takes off by ski jump: there are problems such as the smal...

example

[0013] Take the takeoff data of a certain plane as an example ( Figure 4 ),From Figure 4 It can be seen that when the aircraft raises the front wheel speed (VR speed), it needs to glide 400 meters and the speed reaches 284 km / h (79 m / s), while when glide 300 meters, the speed only reaches 93 km / h (26 m / s) , The distance to VR speed is only 100 meters. During the experiment, the aircraft is placed on the conveyor belt, the auxiliary towing rope and the towing rope are connected with the aircraft, the aircraft starts and accelerates, and the transmission belt starts and accelerates in the reverse direction. At this time, the tires of the aircraft rotate together with the transmission belt. / Hour (26m / s), the aircraft is equivalent to reaching a speed of 93km / h (26m / s) after taxiing 300 meters on the runway. At this time, the transmission belt is decelerated, the auxiliary towing cable and the towing cable After falling off from the aircraft in turn, the aircraft will quickly slid...

Abstract

The invention provides a method for reducing sliding distance of an airplane during landing and taking off, which belongs to the technical field of aircraft carriers. The method comprises a conveying belt, a sub haulage cable, an anti-backing roller and wall and a haulage cable; and scheme is as follows: (1) the airplane is started and accelerated together with the conveying belt on the conveying belt, the conveying belt moves reversely, the pulling cable is separated from the airplane while the pull force of the pulling cable reaches 0.1-1000 N, and the airplane rushes out of the conveying belt to take off; and (2) after the airplane lands on or slides to the conveying belt reverse to the airplane operation direction, the airplane engine is stopped and the conveying belt is decelerated until parking, and then the airplane lands successfully. The method provided by the invention, which is a novel takeoff and landing mode, is superior to the traditional airplane takeoff and landing mode and especially suitable for carrier on the aircraft carrier to take off; the sliding distance of the airplane during taking off and landing can be reduced; the airplane can directly take off or land on the conveying belt under the circumstance that the airplane performance and pilot physical fitness permits; and the method also has the characteristics of low manufacturing cost, simplicity for manufacturing, less energy consumption and simplicity in operation.

Description

Technical field [0001] The invention relates to a method for shortening the taxiing distance of an aircraft during take-off and landing, and belongs to the field of aircraft carriers. The present invention is mainly to start, accelerate or land the aircraft on the conveyor belt, thereby achieving the purpose of shortening the taxiing distance of the aircraft during take-off and landing. Background technique [0002] There are currently three main ways for airplanes to take off: 1. The airplane takes off after taxiing on a land runway: there is a problem that the airplane needs to taxi for a long distance on a land runway. 2. The aircraft uses a steam catapult to increase the initial speed of the aircraft to take off: there are problems with the steam catapult, such as difficulty in manufacturing, complicated manufacturing technology, difficult operation, and high energy consumption. 3. The aircraft takes off by skidding: there are problems with the aircraft taking off with a sma...
