Embodiment Construction

[0017] The present invention is described in further detail below in conjunction with accompanying drawing:

[0018] As shown in Fig. 1 and Fig. 2, the turbine-rocket embedded engine of the present invention is made up of turbine engine 1 and solid (or liquid) rocket engine 3, and turbine engine 1 adopts hollow shaft design, and shaft front end is designed into taper, and shaft The front turbine engine intake cone 2 is longer, which not only provides a larger charge space, but also reduces the weight of the engine, and also plays a role in pre-compressing the airflow.

[0019] The rocket engine 3 is embedded in the intake cone 2 and the hollow shaft of the turbine engine, which effectively utilizes the internal space of the engine. During operation, the adjustable baffle plate of the tail nozzle is opened, and the propulsion is generated by propellant combustion.

[0020] The working principle and process of the turbine-rocket embedded engine of the present invention are: when...

Abstract

The turbine-rocket inlaid type engine of the invention relates to a propulsion system combined by a turbine engine and a rocket engine. The invention integrates the optimum working state of the turbine engine and the rocket engine in an engine cycle, and on the basis of the existing combined engine, a turbine engine and adopts a novel structure engine which leads a hollow shaft and a rock engine to be inlayed in the air inlet cone and the hollow shaft of the turbine engine is provided, and thereby effectively using the interior space of the turbine engine. The invention has the advantages that the novel turbine-rocket inlaid type engine has the advantages that the structure is more compact, the assembling and the disassembling are convenient, the maintenance is easy, the reliability is high, the rang is far, the structure is simple, and the weight is light is light, as well as the residue discharge capacity is few.

Description

technical field [0001] The invention relates to a propulsion system combined with a turbine engine and a rocket engine, and is especially applied to an aerospace reciprocating propulsion system with high energy, variable thrust and low signal characteristics. Background technique [0002] So far, for a hypersonic vehicle with a very wide flight envelope (altitude 0-40km or higher, flight Mach number extending from subsonic, transonic, supersonic to hypersonic), there is no engine that can stand alone To complete the propulsion task, foreign countries have proposed the idea of ​​using two or more engines combined as hypersonic propulsion power. [0003] The turbine-rocket engine combines the advantages of the turbine engine and the rocket engine when they work alone, so that the propulsion system using this engine can obtain good propulsion performance under different flight conditions. However, the currently studied combined engine puts the rocket propellant in front of the...
