Embodiment Construction

[0021] This embodiment is an air intake regulating structure of a solid impulse engine.

[0022] refer to Figure 1 to Figure 8 , the air intake adjustment structure of the solid impulse engine is composed of the solid impulse engine and the intake adjustment structure. The gas generator 1 of the solid impulse engine is fixed in the engine casing 16 and installed at the front of the engine combustion chamber 14. The solid charge Placed in the engine combustion chamber 14, the igniter 13 is installed in the engine combustion chamber 14 and fixed in the round hole at the end of the solid charge, near one end of the tail nozzle 12, the gas generator nozzle 15 and the igniter 13 are coaxially installed.

[0023] The air intake adjustment structure includes an air inlet fixed section 2, an air inlet adjustable section 4, a flexible connecting section 3, a first connecting rod 5, a second connecting rod 9, an outlet reversing ball 8, an actuating connecting rod 7, a second connectin...

Abstract

The invention discloses an air intake adjustment structure of a solid impulse engine. By adjusting the air intake angle and changing the air swirling or non-swirling air intake mode, the adjustment and supplementary combustion chamber gas mixing is realized, and the thrust of the engine is adjusted. . The fixed section of the intake port is installed on the engine casing, the fixed section of the intake port is connected with the adjustable section of the intake port through a flexible connection section, and the adjustable section of the intake port is connected with the combustion chamber of the engine through the outlet reversing ball; the first The drive motor and the second drive motor are respectively connected to the actuating link of the adjustable section of the intake port, and the second drive motor is connected to the casing wall of the engine combustion chamber through the reversing guide groove; the adjustable section of the intake port is connected to the first drive motor Under the joint action of the second driving motor, the reversing ball can be rotated at any angle within the conical rotation range with the outlet reversing ball as the center and the apex angle being 120°, which greatly improves the thrust and maneuverability of the solid-impact engine; The air conditioning structure is simple in structure and easy to implement.

Description

technical field [0001] The invention relates to the technical field of sub-combustion rate ramjet engines, in particular to a sub-combustion rate ramjet intake structure with a variable intake mode. Background technique [0002] Thrust adjustment technology is an important field of solid-state engines. Compared with single-chamber dual-thrust engines and pulse engines with predetermined thrust, the former can distribute propellant energy more reasonably and adjust its thrust according to the needs of aircraft. development trend. [0003] At present, relevant research institutions at home and abroad are all committed to the research of thrust control. The typical structures of several adjustable thrust solid rocket motors include: the engine that adjusts the throat area of ​​the nozzle, the control of the propellant mass burning rate and the flameout engine. , mass-added engines, these engines have been better applied to solid rockets, but they will also bring some new probl...
