The invention relates to the field of rocket engines, in particular to a valve element, a regulating valve and a thrust regulating system. The valve element comprises a valve element body and a valverod. The valve rod is spheroidal; the valve rod is vertically arranged on the valve element body; a through hole is formed in the valve element body, the through hole comprises two right-angle sides and a curve on a projection parallel to the axial direction of the valve rod, one of the right-angle sides is vertical to the axial direction of the valve rod while the other right-angle side is parallel to the axial direction of the valve rod; and the projection area of the through hole from the end point of the right-angle side vertical to the valve rod to the intersection of the two right-anglesides is increased gradually. By applying the valve element arranged by the method to the thrust regulating system, the thrust regulating system has the advantage of being convenient to operate by wayof controlling a thrust by operating a valve flow area of regulating valve and has relatively excellent reliability.
Description
technical field [0001] The invention relates to the field of rocket engines, in particular to a valve core, a regulating valve and a thrust regulating system. Background technique [0002] A jetpack is a small, one-person flying device that can fly autonomously using its own power system. The rocket backpack is a kind of flying backpack. The power system of the flying backpack can be divided into rocket engine, fan, propeller and turbojet engine. Among them, the rocket backpack powered by rocket engine is the most lightweight, easy to carry and wear, and has good application prospect. [0003] The power source of the rocket engine is mainly single-component propellant and two-component propellant. The former mostly uses the high-temperature and high-pressure gas product produced by the catalytic decomposition of hydrogen peroxide as the working medium, while the latter uses the oxidizer and fuel to burn to obtain the working medium. Moreover, in order to reduce the structu...
