The invention provides a telescopic cylinder electromagnetic rail steam ejection device for carrier-based aircraft, which can effectively solve the problem of assisting the flight of carrier-based aircraft. The technical solution includes changing the complex locking structure of the original slit cylinder, and setting linear guide rails inside it to form slits The cylinder rail structure is connected with the ejection main cylinder as a whole, and the telescopic cylinder with inner guide rail is set in it, guided by the guide rail support plate into the rail, forming a large-stroke telescopic cylinder inner and outer guide rails to support the horizontal stroke structure, and the telescopic cylinder terminal inside The pipe cavity allows the steam pressure to directly act on the effective area of the traction piston, combined with the mechanical thrust of the telescopic cylinder under pressure, to form a linked ejection structure. The fast rhythm is just in line with the flight aid requirements of carrier-based aircraft, especially the electromagnetic rail scheme included in it makes the electromagnetic ejection and steam ejection technology organically combined, which is the innovation of the main essence of steam ejection. The invention has a simple structure, is stable and reliable , low cost and good effect.
Description
technical field [0001] The invention relates to the ejection and take-off technology of aircraft carrier aircraft, in particular to a telescopic cylinder electromagnetic rail steam ejection device. Background technique [0002] Carrier-based aircraft catapult technology is an effective way to solve the problem of aircraft carriers with limited deck space to boost carrier-based aircraft to take off within a short distance. The only steam catapult currently used is a technology invented in the 1950s. This technology can be used today. It is because it has high power, strong ejection force, stable structure, and has been verified by actual combat that this technology is mature and reliable. However, people have also found many technical shortcomings in it in practice, such as huge system, complex and The rate is low, especially the manufacturing process of the ejection body slotted cylinder is difficult, the material requirements of the airtight accessories are high, the replac...
