Rocket thrust chamber provided with acoustic cavity and applied to supersonic airliner and supply system thereof

Abstract

The invention relates to a rocket thrust chamber provided with an acoustic cavity and applied to a supersonic airliner and a supply system of the rocket thrust chamber and belongs to medium-pressure afterburning rocket engines adopting 70%-75% hydrogen peroxide / aviation kerosene. The rocket thrust chamber aims to achieve the purpose that a rocket engine meeting the use requirements of the supersonic airliner can be researched. According to the rocket thrust chamber, the thrust chamber technical schemes comprising a triple-bottom head structure with the acoustic cavity, two kinds of gas-liquid jet units, a tube bundle type body structure and the like are adopted, a medium-pressure afterburning system is adopted, and a source gas system supplying oxygen and steam to an airliner gas source system is arranged. The rocket thrust chamber has the main advantages that the burning temperature of the thrust chamber is quite low, the number of the decomposition problems of the reactor is quite small, cooling of the body of the thrust chamber is quite reliable, the acoustic cavity can effectively conduct damping, the technological difficulties are greatly lowered, and the conditions for researching the rocket engine for the supersonic airliner at a low cost within a short time are provided. The rocket thrust chamber provided with the acoustic cavity and applied to the supersonic airliner is mainly applied to the supersonic airliner and suitable for rocket aircrafts, aerospace planes, starships, launchers, liquid missiles and the like.

Description

technical field [0001] This invention relates to hydrogen peroxide / kerosene rocket engines for aircraft. Background technique [0002] Civil aviation aircraft are safe and applicable, but the long intercontinental flight takes more than ten hours, and passengers are tired. Reminiscent of the benefits of high-speed rail and bullet trains, long-range civil aviation aircraft should also double in speed and become supersonic airliners that cruise at 2-3 times the speed of sound. [0003] As early as 1976, Europe had just developed the supersonic passenger plane of the Wa, which was a passenger plane with a swept-back wing propelled by a high-thrust aerojet engine. This kind of aircraft has shortcomings such as insufficient safety, many faults, high maintenance costs, and loud take-off noise. It was decommissioned three years after the air crash in 2000. [0004] Recently, Europe and the United States have re-developed a new generation of supersonic airliners. The "N+2" commer...

Problems solved by technology

I have an approved utility model patent (ZL201320842845.6) for "a medium-concentration hydrogen peroxide / kerosene combustion chamber without a catalytic bed", which improves safety and usability, but this small-scale combustion chamber for both military and civilian purposes remains unchanged. Vibration facilities cannot be used on liquid rocket engines of supersonic airliners
