Aircraft takeoff traction apparatus

Abstract

The invention belongs to the technical field of aeronautical facilities and in particular relates to an aircraft takeoff traction apparatus. The aircraft takeoff traction apparatus comprises an upper plate and a lower plate, which are arranged at the top and the bottom;the corresponding parts of the upper plate and the lower plate are respectively provided with gaps matched with aircraft wheels in a length direction; rollers are arranged at the bottom of the lower plate; the rollers are connected with a transmission mechanism; the aircraft takeoff traction apparatus further comprises mobile bottom plates, which are arranged correspondingly to the gaps of the upper plate and the lower plate; and the mobile plates are connected with lifting mechanisms. The aircraft takeoff traction apparatus is simply structured and skillfully designed and is advantaged in that the takeoff oil consumption of an aircraft can be effectively reduced, the flying range of the aircraft can be prolonged, the takeoff efficiency can be greatly increased and the takeoff frequency can be also increased.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment, and in particular relates to a traction device for aircraft take-off. Background technique [0002] The fighter jet in the prior art needs a long time to adjust its position after receiving the flight order, and slides to the runway by consuming fuel, and takes off against the wind after being accelerated to about 240km / h. As for the carrier-based fighter of an aircraft carrier, since the length of the carrier-based airway is about 200 meters, additional assistance is needed to speed up the fighter, such as using steam catapult, electromagnetic catapult, or designing the take-off section of the carrier's airway to rise to a certain degree. Angle, in order to match the fighter jets into the air against the wind. There are following problems in the fighter take-off mode in the prior art: [0003] 1) The fighter needs to consume about 10% of the fuel in the fuel tank as power output fro...

AI Technical Summary

Problems solved by technology

[0003] 1) The fighter needs to consume about 10% of the fuel in the fuel tank as power output from the stop to the runway, and it takes a long time, especially for carrier-based fighters, due to the fixed deck area, the movement is greatly restricted;

[0004] 2) At present, most carrier-based fighters adopt hydraulic folding wing design, which can fold the wings when the fighter is parked to save space. However, the hydraulic folding equipment weighs about 400 kg, which not only increases the load of the fighter, but also affects the wings. affect the overall strength of

[0005] 3) For the take-off runway of fighter jets on land, since the take-off of fighter jets can only rely on their own acceleration, the length of the runway is relatively large. Airway, the deck rises in the take-off section of the airway, which not only increases the weight and cost of the deck, but also makes the deck unable to be used for other purposes, and the idle rate is high;

[0006] 4) Most fighter jets in the prior art take off against the wind, but for downwind weather, the speed needs to be increased again to create a relatively headwind take-off condition, which is a technical challenge for carrier-based fighters

[0007] Similarly, for passenger aircraft and large transport aircraft, there are also problems of high fuel consumption, long time consumption and long runway when taxiing on the ground before takeoff
