Problems solved by technology

[0004] The purpose of the present invention is to provide an ejection-assisted turbo-ram-press combined cycle engine, which uses a turbine to replace the rocket booster, in view of the bottleneck problem that the specific impulse in the rocket ram-press combination is relatively small and the turbo-ram-press combination cannot be transferred. To overcome the high fuel consumption rate of take-off, the ejector combustion is used to overcome the problem of low efficiency of the Ma2-3 ramjet engine, so the advantages of each engine can be fully utilized, and the difficulty of switching between various types of engines can be solved

Embodiment Construction

[0015] The structure, principle and working process of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 ~ Figure 4 As shown, the ejection-assisted turbo-ramjet combined cycle engine (E-TBCC engine) of the present invention is based on the integration of the engine and the aircraft, and the wall ejection rocket 19 or the support plate ejection rocket 24 and the dual-mode scram The ramjet engine 16 is integrated, and the method of wall injection or support plate injection is adopted to solve the problem of insufficient thrust when the turbine engine mode is converted to the ramjet engine mode. This combined cycle engine mainly consists of a turbine engine (turbojet or turbofan engine) 7, a dual-mode scramjet 16, a plurality of side-by-side wall ejection rockets 19 and a plurality of side-by-side grooves (or a plurality of Support plates arranged side by side to eject rockets and multiple su...

Abstract

The invention discloses an ejector-assistant turbine-based combined cycle engine, and relates to a reusable combined cycle engine applied to aircrafts and spacecrafts. The engine mainly consists of a turbine engine, rocket ejectors and a dual-mode scramjet engine, wherein the turbine engine and the scramjet engine work in parallel, and the rocket ejectors and the scramjet engine are in integrally designed. When the engine is converted from a turbine engine mode to a scramjet engine mode, ejection fuel-gas streams are ejected into the scramjet engine from support plates or side walls of the scramjet engine; inlet air of the scramjet engine is mixed with the ejection fuel-gas streams, and afterburning is performed. The fuel gas ejected by the rocket ejectors can overcome the defect that thrust is not enough when the turbine engine mode is converted into the scramjet engine mode, so that the combined engine disclosed by the invention can has the advantage of smooth transition during mode conversion.

Description

technical field [0001] The patent of the present invention relates to a novel combined engine, in particular to a reusable Ejector-Assistant Turbine-Based Combined Cycle (Ejector-Assistant Turbine-Based Combined Cycle, referred to as E-TBCC) engine applied to aerospace vehicles. Background technique [0002] Combination engine is an important development direction of aerospace integrated weapon system in the future, and it will also be the main power form of next-generation aerospace vehicles. At present, combined engines include two categories: turbine-based combined cycle engines (Turbine Based Combined Cycle, hereinafter referred to as TBCC) and rocket-based combined cycle engines (Rocket Based Combined Cycle, hereinafter referred to as RBCC). The TBCC power system is an air-breathing engine that is organically combined with a turbojet (or turbofan) engine and a ramjet; RBCC is a combined cycle system that organically combines a rocket and a dual-mode ramjet. With the in...
