Abstract

FIELD: engine engineering. SUBSTANCE: chamber is a Hartmann generator and consists of resonator and Laval nozzle mounted inside the common housing. When fuel components are supplied to the mixing chamber they are mixed. The working mixture obtained flows through the throat and enters the nozzle of external expansion which always operates in steady- state condition. The mixture being accelerated up to MM≥22 enters the resonator space wherein oscillation is exited and shock waves occur that in turn generate detonation waves. The thrust occurs due to interaction of the detonation wave with the resonator bottom as well as due to propulsion force exerted by supersonic jet that outflows from the nozzle. EFFECT: simplified design and decreased sizes.

Камера двигателя представляет собой генератор Гартмана и состоит из резонатора и сверхзвукового сопла, установленных в едином корпусе. При подаче компонентов топлива в смесительную камеру, в ней происходит процесс смешения. Образовавшаяся рабочая смесь, истекая через критическое сечение, попадает в сопло внешнего расширения, которое работает всегда на установившемся режиме. Разогнанная до скорости М ≥ 2 рабочая смесь попадает в полость резонатора, в которой возбуждается колебательный процесс с образованием ударных волн, которые генерируют детонационные волны. Сила тяги создается за счет взаимодействия детонационной волны с дном резонатора, а также за счет реактивной силы, образованной истекающей через сопло газовой сверхзвуковой струей. Упрощение конструкции двигателя и уменьшение его габаритов осуществляется за счет исключения из него элементов системы инициирования. Повышение экономичности работы двигателя осуществляется за счет применения сопла внешнего расширения с центральным телом, которое обеспечивает постоянный расчетный режим работы, что предполагает меньшее давление в камере смешения и соответственно в системе подачи компонентов топлива.The engine chamber is a Hartmann generator and consists of a resonator and a supersonic nozzle mounted in a single housing. When the fuel components are fed into the mixing chamber, a mixing process takes place in it. The resulting working mixture, flowing out through the critical section, enters the nozzle of the external expansion, which always works in steady state. Accelerated to a speed of M ≥ 2, the working mixture enters the cavity of the resonator, in which the oscillatory process is excited with the formation of shock waves that generate detonation waves. The traction force is created due to the interaction of the detonation wave with the bottom of the resonator, as well as due to the reactive force generated by the supersonic gas stream flowing through the nozzle. Simplification of the engine design and reduction of its dimensions is carried out by eliminating elements of the initiation system from it. Improving the efficiency of the engine is due to the use of an external expansion nozzle with a central body, which provides a constant design mode of operation, which implies less pressure in the mixing chamber and, accordingly, in the fuel component supply system.
