Novel series of hydrogen peroxide thrust chambers used for rockets and airships

Abstract

The invention relates to novel series of hydrogen peroxide thrust chambers used for rockets and airships. The novel series of hydrogen peroxide thrust chambers comprise micro attitude control types, small-sized orbit control types, middle-sized acoustic cavity types, large-sized partition types and ultra-large types; industrial 79.1%-84.9% hydrogen peroxide is used as an oxidizing agent and a regenerative coolant; a non-toxic homogeneous miscible fuel (NHMF), kerosene or liquid hydrogen is taken as a fuel; non-toxic storable components account for 95%-100% of a propellant, so that the use is convenient; the decomposition rate of a catalyst bed is controlled within 75%-95%, the development and service life prolonging of the catalyst bed are facilitated; and novel structures such as a high strength head, a regenerative cooling nineteen-zone partition, a semi-opening acoustic cavity, a gas-liquid impinging injector, a multihole conical shell are adopted. According to the novel series of hydrogen peroxide thrust chambers used for rockets and airships, the combustion temperature, decomposition temperature and regenerative cooling temperature rise are low, so that the working conditions are improved at lot; besides, the density-specific impulse is higher, the propulsive performance is better, and therefore the thrust chambers are applicable to boosters, first-stage and second-stage engines as well as first-stage core engines, which are capable of being used for over 25 times, of novel manned Moon and Mars landing rockets and airships.

Description

technical field [0001] The invention relates to a series of hydrogen peroxide thrust chambers for novel rockets and spaceships, and belongs to the technical field of liquid rocket engines. Background technique [0002] After more than 70 years of development, the world's rockets, spacecraft and their engine technology have made great achievements. The new direction of development is to develop new types of rockets and spacecraft and their applicable engines that can be reused more than 25 times, manned to the moon and Mars. [0003] The current high-pressure supplementary combustion liquid oxygen kerosene engine and liquid oxygen liquid hydrogen engine are very advanced, but the technology is difficult. The structure of the thrust chamber with three bottoms and two cavities and four bottoms and three cavities and thousands of nozzles are cumbersome to process, the strength of the head is not high, and it is not easy to increase the thrust more. In addition, frozen propella...

AI Technical Summary

Problems solved by technology

The fly in the ointment is that the specific impulse value of the engine using kerosene fuel is low, and ignition starts with the help of electric spark plug or igniter, which is not suitable for attitude control and orbit control engines of spacecraft and satellites, and the structure of the thrust chamber is not suitable for superpower in terms of strength and other aspects. large engine
