Description

Manual Full floating steam compression catapult

Technical field

[1] The present invention relates to an aircraft steam ejector for use on an aircraft carrier, and more particularly to a pneumatic compression ejector

[2] Background Art

[3] In order for an aircraft to take off from an aircraft carrier, the thrust generated by the steam catapult must be used. The steam catapult was invented by the British, but so far, only the United States has created a steam catapult that can be used in actual combat. The main body of the steam catapult is a large reciprocating cylinder that converts steam energy into kinetic energy for ejection. The high temperature and high pressure steam are generated by the ship's propulsion boiler and stored in the accumulator tank. The input and pressure regulation of the steam in the accumulator tank is controlled by the valve. The US aircraft carrier's active steam catapult uses a slotted cylinder with a piston inside it. The piston needs to be connected to the slider through the cylinder wall. The slider connects the landing gear of the aircraft through the towing hook. Therefore, the slotted cylinder has a slit from the beginning to the end. This seam is normally sealed, and the piston opens when the piston passes, and the piston closes and then closes. Slotted cylinders have two biggest problems:

[4] The first is the problem that the cylinder itself is deformed after being heated, and the open cylinder is subjected to the pressure generated by high temperature and high pressure steam.

Since there is an opening in the cylinder wall, the force characteristics of the open cylinder are very poor, and it is quite difficult to achieve no deformation. Once the cylinder is deformed, the cylinder straightness decreases, and the slider passes through the cymbal, which will jump between the smooth track and the cylinder and the track.

[5] The second is difficult to seal, the open cylinder seal is the key, the sealing performance of this position is very important, related to the safety of ejection. Old-fashioned catapults use a rubber band placed on either side of the cylinder opening to form a "zipper" seal. The active catapult uses a U-shaped seal to fill the opening of the cylinder, no matter which method, maintenance cost. Large, U-shaped sealing strips are frequent and cumbersome to replace, and have high material requirements. Although it is no problem to meet the needs of aircraft take-off, it is impossible to achieve the same degree of sealing as a steam engine cylinder, so each time it is ejected, A high-temperature white smog will be scattered from under the deck. This is a leak of high temperature, high pressure steam, which not only consumes a lot of fresh water, but also wastes a lot of energy. The biggest problem with the steam catapult is that it is impossible to increase the speed and the strength of the same speed, and it is impossible to achieve the best cooperation, so that the aircraft takes off slowly. It is precisely because of the above problems that the US Navy is actively developing a more reliable steam catapult, but it has not been successful yet.
