FLOW REGULATOR FOR GAS GENERATION PRODUCTS OF A RAM ROCKET ENGINE Russian patent published in 2021 - IPC F02K7/18 B64D27/20 

FIELD: rocket technology.

SUBSTANCE: invention relates to rocket technology, namely to devices designed to regulate the flow rate of gas generation products in ram rocket engines (RRE). The gas generation products flow regulator is located between the gas generator and the afterburning chamber and contains front 1 and rear 2 covers with a heat-protective coating 3 (10), a passage channel 4, offset relative to the longitudinal axis of the regulator in the radial direction and closed with a heat-protective coating 5, the nozzle liner 6 made of composite tungsten-copper pseudoalloy, an electric drive with a gearbox 7, on the shaft 8 of which a mushroom-shaped rotary flap 9, also made of composite tungsten-copper pseudoalloy, is fixed. On the front cover there is a radial groove 11, the geometric dimensions of which are selected by calculation to ensure the minimum area of the passage section with the fully closed rotary flap 9 and a cutout of complex shape 12 in the area of the passage channel 4. The nozzle insert 6 has a flange 13 at the inlet, repeating the shape of the cutout 12, while the front plane of the flange is installed on the same level with the plane of the front cover 1, the flange has a radial groove 14 of the same dimensions as the radial groove 11, and the rear face of the protrusion of the rotary flap 9 rests on the front plane of the flange.

EFFECT: invention provides simpler design, better manufacturability reduction in the mass-dimensional characteristics of the flow regulator of gas generation products of the RRE, and also ensures its operability when the condensed phase adherence and optimal mixing of the rocket fuel components in the afterburning chamber.
