Embodiment Construction

[0014] The variable structure rocket-based combined power cycle engine of the present invention, such as figure 1 and figure 2 As shown, it includes a variable structure combustion chamber c, which is a cavity surrounded by an upper top plate, side plates and a fixed bottom plate 6, and the upper top plate includes a slidingly connected combustion chamber fixed top plate 4 and an adjustable combustion chamber from front to back. The top plate 5 has the same width. The fixed top plate 4 of the combustion chamber is inclined upward from front to back, and the adjustable top plate 5 of the combustion chamber slides reciprocally along the direction of the fixed top plate 4 of the combustion chamber; the fixed top plate 4 of the combustion chamber is the incoming flow inlet port ; In the injection mode, the adjustable top plate 5 of the combustion chamber is located at the rear end of the fixed top plate 4 of the combustion chamber to maximize the expansion ratio of the combustion...

Abstract

The invention discloses a variable-structure rocket based combined power cycle engine. The variable-structure rocket based combined power cycle engine comprises a variable-structure combustion chamber which is a cavity defined by upper top plates, side plates and a fixed bottom plate, wherein the upper top plates comprise a combustion chamber fixed top plate and a combustion chamber adjustable plate, which are in sliding connection from front to rear, and are consistent in width; the combustion chamber fixed top plate is upwards arranged in an inclined mode from front to rear; the combustion chamber adjustable top plate slides back and forth along the trend of the combustion chamber fixed top plate; and a combustion chamber fixed top plate end is an inflow inlet end. The variable-structure rocket based combined power cycle engine disclosed by the invention improves combustion performances, meets matching of a gas inlet system and a gas exhaust system, and improves performances of a tail spray tube.

Description

technical field [0001] The invention belongs to the technical field of rocket-based combined cycle engines, in particular to variable-structure rocket-based combined power cycle engines. Background technique [0002] Rocket-based combined power cycle engine, namely Rocket-Based-Combined-Cycle, referred to as RBCC engine. The engine is a combined propulsion system that organically integrates a rocket engine with a high thrust-to-weight ratio and low specific impulse and a ramjet engine with a low thrust-to-weight ratio and high specific impulse. The modal and the pure rocket mode are integrated, so that the RBCC engine can start automatically, has a wide flight envelope, and has strong task adaptability, making it one of the most promising new power devices in the future. The combustion chamber / tail nozzle is an important part of the engine. For the air-breathing engine, the combustion chamber is required to enable the fuel to complete the injection, atomization, evaporation...
