Suction type rocket combination circulation engine

Abstract

The invention relates to a suction type rocket combined cycle engine which belongs to the technical field of combined engines applied to aircrafts and astronautic carriers. The invention includes a turbine engine, a rocket engine and a ramjet engine; the hollow shaft design is adopted for the turbine engine; a rotating ramjet compressed rotor based on the laser compression technology is used to replace the current compressor as a compression component; the rocket engine is laid in a cone in the turbine engine, which consists of an intake cone, a hollow shaft and a tail spray pipe; when the turbine engine works, the closed rocket engine can adjust the tail spray pipe to be the cone of the turbine engine; the turbine and the ramjet engines are integrated with the aircraft body; the front aircraft body pre-compresses the air flow into the turbine or ramjet engines. The invention has the advantages of reusability, compacted structure and light weight, as well as integration of advantages of single rocket engines and ramjet engines and solving the deficiencies of the single rocket and ramjet engines.

Description

technical field [0001] The invention relates to a combined engine, in particular to a reusable air-breathing-Rocket Combined Cycle (ARCC) engine applied to aerospace aircraft and space vehicles. Background technique [0002] At present, the propulsion systems (engines) commonly used in aerospace planes and space vehicles mainly include rocket engines and ramjets. The rocket engine is the most mature engine so far. Its advantages are that it does not rely on oxygen in the atmosphere, but carries propellants (including oxidants and fuel) as energy sources, which can work in and out of the atmosphere, and are not affected by the atmosphere. The influence of the flight speed of the aircraft; its disadvantages are: it needs to bring a large amount of oxidant, usually the weight of the oxidant accounts for about two-thirds of the total take-off weight, its specific impulse is relatively low, the payload is small, the flight cost is high, and the time is short, And generally not r...

AI Technical Summary

Problems solved by technology

The rocket engine is the most mature technology so far. Its advantages are: it does not rely on the oxygen in the atmosphere, but carries its own propellant (including oxidizer and fuel) as an energy source, can work inside and outside the atmosphere, and is not affected by The impact of the flight speed of the aircraft; its disadvantages are: it needs to carry a large amount of oxidant, usually the weight of the oxidant accounts for about two-thirds of the total take-off weight, its specific impulse is relatively low, the payload is small, the flight cost is high, and the time is short. and generally not reusable

The advantages of the ramjet engine are: simple structure, relatively light weight, convenient use and maintenance, low cost, large specific impulse, and large payload. The disadvantages are: it cannot start by itself, and the efficiency is low at low speeds; The shortcomings of the engine not being able to start itself and low efficiency at low speeds, however, will undoubtedly increase the weight of the entire propulsion system and complicate the structure of the entire propulsion system
