Device employed to assist shipboard aircraft in takeoff

Abstract

The invention relates to a device employed to assist shipboard aircraft in takeoff. The device comprises a steam generator provided with a steam outlet and a steam return port, and a transmission chamber communicated with the steam outlet and the steam return port of the steam generator respectively; the wall of the transmission chamber is rotationally provided with a transmission shaft in form of hermetic seal; one end of the transmission shaft is configured to be a power input end extending into the transmission chamber, the other end of the transmission shaft is configured to be a power output end extending out of the transmission chamber; a steam impeller is coaxially fixed on the transmission shaft in the transmission chamber; a driver gear is coaxially fixed on the power output end of the transmission shaft; the device employed to assist shipboard aircraft in takeoff further comprises a takeoff-assisting track tipsily arranged in the transmission direction and engaged with the driver gear; both ends of the takeoff-assisting track are provided with a main tensioning wheel respectively; the middle part of the takeoff-assisting track is provided with a loading wheel; and the periphery of the takeoff-assisting track is provided with a limiting structure used for limiting the airplane wheels of corresponding shipboard aircraft. By using the track with high bearing property in the invention, the invention provides the device employed to assist shipboard aircraft in takeoff, which is suitable for large and middle shipboard aircrafts.

Description

technical field [0001] The invention relates to a flying aid device for large and medium-sized carrier-based aircraft to take off on an aircraft carrier. Background technique [0002] The flying aid device is an auxiliary tool for the aircraft to achieve ultra-short-distance take-off. According to the quality, shape, and performance of the aircraft, it is given huge energy in a short period of time, so that it can obtain a larger initial speed to achieve the purpose of take-off, so as to realize various types of aircraft. shipboarding. Nowadays, steam catapults are generally used in aircraft carriers, but they consume a lot of energy and can only accelerate small aircraft, but cannot take off large and medium-sized aircraft, which seriously limits the development of the navy. Due to the impact of technical funds, etc., the carrier-based flying aids for large and medium-sized aircraft are still blank in the world. [0003] At present, there are mainly three types of catapul...

AI Technical Summary

Problems solved by technology

[0009] (1) The maintenance cost is high, the U-shaped sealing strip is frequently replaced and very troublesome, and the material requirements are high;

[0010] (2) The cost of using steam catapults is high, the efficiency is low, there are many supporting facilities, the system is cumbersome, and the requirements for each link are high;

[0011] (3) It needs to consume a lot of fresh water. The United States once considered a steam condensation recovery device for this purpose, but it was finally canceled due to its large size and low efficiency.

What's more terrible is that the initial pull of this catapult is very large, the pilot will faint for a short time, and the structural strength of the aircraft is also very high.

And the pulling force at the end of the work is very small, and it cannot be boosted for take-off at critical times
