Water turbine type aircraft constant torque arresting adjusting system

Abstract

A water turbine type aircraft constant-torque arresting adjusting system is characterized in that a shell is filled with a fluid medium, an upper stator, a rotor and a lower stator are located in the shell, the upper stator is fixedly connected with the shell, a rotating shaft penetrates through a top plate of the shell and is fixedly connected with the rotor, a push rod penetrates through a bottom plate of the shell and is fixedly connected with the lower stator, and a rope belt disc wound with an arresting belt is fixedly arranged at the top of the rotating shaft; the cams are located below the push rod and make contact with the push rod through rollers, the cams are arranged on the cam shaft and can change positions so as to achieve multiple purposes, and the rotating shaft is in transmission connection with the cam shaft through a speed reducing mechanism. After an aircraft lands, the arresting belt stops and drives the rotor to rotate, inertia kinetic energy of the aircraft is consumed under the damping action of a fluid medium, meanwhile, the cam is driven to rotate through the speed reducing mechanism, the axial gap distance between the stator and the rotor is changed through movement of the push rod, then the arresting force is changed, and the peak load of the aircraft when the aircraft is arresting is effectively reduced. Meanwhile, the deceleration of the aircraft during arresting is reduced, the service life of the aircraft is prolonged, and the body discomfort of a pilot is reduced.

Description

technical field [0001] The invention belongs to the technical field of aircraft arresting, in particular to a water turbine type aircraft constant moment arresting adjustment system. Background technique [0002] At present, the arresting system used by aircraft is mainly water turbine brakes. The traditional water turbine brakes belong to the "one machine, one use" type, that is, they are customized according to the specific model parameters of the aircraft. If the water turbine brake is customized for light aircraft, then the water turbine brake cannot meet the arresting requirements of heavy aircraft. If it is used for arresting heavy aircraft, the arresting distance of heavy aircraft may exceed the set limit value, resulting in The heavy aircraft overshot the runway and was damaged. If the water turbine brake is custom-made for heavy aircraft, then the water turbine brake cannot meet the arresting needs of light aircraft. damaged by overloading. [0003] Therefore, in...

AI Technical Summary

Problems solved by technology

Although the arresting safety of different types of aircraft can be guaranteed by configuring multiple sets of water turbine brakes, it also leads to the disadvantages of cumbersome installation and maintenance, and poor economy

[0004] In addition, the traditional water turbine brake cannot adjust the output arresting force, resulting in a large load at the moment the aircraft is blocked, and the large load immediately decays after reaching the peak value, resulting in the deceleration of the aircraft when it is blocked. Huge, excessive deceleration acts on the aircraft fuselage, not only will reduce the service life of the aircraft, but also the pilot will cause serious physical discomfort in the environment of excessive deceleration
