Embodiment 1

[0018] The present invention is an integrally designed cooling structure for a new generation combined cycle engine, ie, RBCC engine propelling chamber, and adopts an integrated fuel supply system.

[0019] The present invention serves as a kind of RBCC engine integrated fuel supply system based on anhydrous hydrazine, see figure 1 , including the engine body, the most front air intake port 41 of the engine body, the incoming air from the intake port enters the ram combustor 42, and the fuel gas in the rocket thrust chamber 40 is recombusted in the ram combustor, and the high-temperature gas generated by combustion passes through the tail nozzle 43 is accelerated to discharge and generate thrust. The fuel supply system of the engine of the present invention is an integrated fuel supply system for RBCC engines based on anhydrous hydrazine. The integrated fuel supply system includes three kinds of propellants of dinitrogen tetroxide, anhydrous hydrazine and kerosene The propella...

Embodiment 2

[0025] The RBCC engine integrated fuel supply system based on anhydrous hydrazine is the same as that in Embodiment 1. The integrated fuel supply system of the present invention is regulated by a sub-system. In the present invention, the dinitrogen tetroxide and kerosene supply system is the main propellant supply system, and the anhydrous hydrazine propellant supply system is the sub-system. The sub-system is equipped with relevant flow regulators for each main system, a fuel path flow regulator 11 is installed for the kerosene supply system, and an oxidant path flow regulator 20 is installed for the dinitrogen tetroxide supply system. During the working process, the flow rate of anhydrous hydrazine is adjusted respectively through the flow regulator 11 of the oxidant path and the flow regulator 20 of the fuel path, thereby changing the power of the single-component gas generator, the speed of the turbo pump and the output power of the oxidizer path and the fuel path to realiz...

Embodiment 3

[0027] The RBCC engine integrated fuel supply system based on anhydrous hydrazine is the same as that in Embodiment 1-2. The oxidant and fuel of the system of the present invention adopt separate supply and adjustment systems, which are continuously adjustable in a single way, and meet the requirements of different working modes of the combined engine.

Abstract

The invention discloses an RBCC engine integrated fuel supply system based on anhydrous hydrazine. The rocket thrust chamber and the ram combustion chamber use the same system to realize the integrated fuel supply and adjustment; the system uses dinitrogen tetroxide, anhydrous hydrazine and kerosene three A storable propellant, which is catalyzed and decomposed with anhydrous hydrazine to drive two turbo pumps respectively, and is squeezed and supplied to the thrust chamber of the rocket when the system is filled, so as to realize spontaneous ignition with dinitrogen tetroxide; anhydrous hydrazine is extruded with a single tank The thrust chamber and combustion chamber are supplied with propellant through a turbo pump; the body of the thrust chamber is cooled by dinitrogen tetroxide, and the ram combustion chamber is cooled by kerosene. The invention overcomes the problems that the combined engine adopts an independent supply system for the rocket thrust chamber and the ram combustion chamber, which leads to complex systems and difficulty in realizing integrated regenerative cooling structure design, satisfies the integrated fuel supply and adjustment of the combined engine, and the overall system is relatively simple and easy accomplish.

Description

technical field [0001] The invention belongs to the technical field of rocket-based combined cycle engines, and mainly relates to an RBCC engine fuel supply and regulation system, in particular to an RBCC engine integrated fuel supply system based on anhydrous hydrazine. This system is used in the system selected by RBCC for integrated fuel supply based on anhydrous hydrazine, and can also be used as an integrated fuel supply system based on other types of propellants. Background technique [0002] The Rocket Based Combined Cycle (RBCC) engine is an advanced propulsion system based on a reusable single-stage orbiting vehicle, which combines the high thrust-to-weight ratio of the rocket engine and the high specific impulse of the ramjet engine. With full airspace and full speed domain working capability and simple structure, it is an ideal power device for weapons and equipment such as near-space long-range strong mobile missile weapons and reusable space-to-ground transport ...
