Winding dragging and take-off accelerating device for shipboard aircraft of aircraft carrier

Abstract

The invention discloses a winding dragging and take-off accelerating device for a shipboard aircraft of an aircraft carrier. A slope groove is formed in a deck surface; a lifting vehicle is mounted in the slope groove; the front wheel of the shipboard aircraft is placed on the lifting vehicle; the rear wheels of the shipboard aircraft are placed on the outer sides of rear wheel guiding column bars on the deck surface on the two sides of the slope groove; a blocking cable / net, a front dragging guiding wheel and a front dragging winding device are fixedly arranged on the deck surface at the front end of the slope groove; a slope groove bridge is arranged on the deck surface at the rear end of the slope groove; a rear dragging guiding wheel and a rear dragging winding device are fixedly arranged on the deck surface out of the slope groove bridge; a rear dragging cable of the rear dragging winding device is connected with the rear end of the lifting vehicle through the rear dragging guiding wheel. According to the invention, when the aircraft accelerates, the front wheel of the aircraft is lifted gradually by the lifting vehicle under the front wheel of the aircraft when the aircraft takes off; angle of elevation of the aircraft and the running speed of the aircraft are enlarged, and the aircraft takes off; optimum uniform acceleration is realized; bomb loading capacity and oil reserve when the aircraft takes off are increased remarkably; campaigning radius is enlarged; the defect that the aircraft cannot be changed for commercial use in peaceful period because the overall width bow is cocked is avoided.

Description

technical field [0001] The invention relates to a device for accelerating the take-off of an aircraft carrier by using a reel hoist to pull and accelerate the take-off of the aircraft carrier. It is especially suitable for both military and civilian aircraft carriers, that is, it can conveniently change the combat military aircraft carrier into a long-range passenger-cargo ro-ro ship for commercial use. technical background [0002] Currently, there are only four ways for carrier-based aircraft to take off: [0003] 1. Change the downward inclination angle of the engine nozzle to increase the lift of the aircraft to achieve short-distance take-off or vertical take-off. The disadvantage is that the fuel consumption is too much during take-off and landing, which reduces the combat radius and the weight of the bomb. And because of adding the transmission device that changes the nozzle inclination angle, the dead weight of the aircraft is increased, which affects the flexibility...

Problems solved by technology

[0005] 3. Ski jump take-off, such as: the Varyag aircraft carrier uses the inertial acceleration force of the aircraft before take-off and the about 13 0 The elevation angle can be used to take off from the ship, eliminating the need for complex and expensive ejection devices such as steam or electromagnetic catapults. The disadvantage is that the afterburner is generally required to take off when taking off, which increases fuel consumption and reduces the idle time of the aircraft.

It can be seen that the main disadvantage of the electromagnetic ejection system is that the energy conversion and storage requirements are too high, the software development is too complicated, and the electromagnetic material consumption is too much, but its utilization efficiency is too low

According to the experience of the United States, the engineering development and system integration work involved in the electromagnetic aircraft ejection system is not only high in development costs but also takes a long time. It is believed that China still needs to solve engineering, system integration, and testing if it wants to apply electromagnetic ejection technology to combat before 2025. with the identification of a series of major problems
