Abstract
1. Газожидкостный реактивный двигатель, содержащий входное устройство, наружный контур, внутренний контур в виде газотурбинного двигателя и камеру смешения обоих контуров, отличающийся тем, что наружный контур двигателя совмещен с наружным контуром силовой установки (мотогондолы) самолета и геометрическим профилированием в соплах контуров, смешиваемые газы разгоняются до сверхзвуковых режимов на входе в камеру смешения, камера смешения, превышающая по диаметральным размерам максимальный диаметр канала наружного контура, выполнена по предписаниям первого закона термодинамики и имеет по длине переходный участок, изохорический участок выравнивания скоростей, изотермический участок выравнивания статических давлений смешиваемых газов и адиабатный участок торможения сверхзвукового потока смешанного газа.2. Двигатель по п.1, отличающийся тем, что камера смешения снабжена устройством преобразования сверхзвукового потока смешанного газа в дозвуковой поток, устройство выполнено в виде цилиндрического канала, площадь поперечного сечения которого соответствует критическому сечению при плавном переходе через скорость звука в дозвуковой поток и является местом образования скачка при переходе через прямой скачок уплотнения в дозвуковой поток в расширяющемся сопле, выполненном в виде выхлопного диффузора.1. A gas-liquid jet engine containing an input device, an external circuit, an internal circuit in the form of a gas turbine engine and a mixing chamber for both circuits, characterized in that the external circuit of the engine is combined with the external circuit of the aircraft power plant (nacelle) and geometric profiling in the nozzles of the circuits, miscible the gases are accelerated to supersonic modes at the entrance to the mixing chamber, the mixing chamber exceeding the maximum diameter of the channel of the external circuit in diametrical dimensions the requirements of the first law of thermodynamics and has a length of the transition section, the isochoric section of the velocity equalization, the isothermal section of the static pressure equalization of the mixed gases and the adiabatic braking section of the supersonic mixed gas flow. 2. The engine according to claim 1, characterized in that the mixing chamber is equipped with a device for converting a supersonic mixed gas stream into a subsonic stream, the device is made in the form of a cylindrical channel, the cross-sectional area of which corresponds to the critical section during a smooth transition through the speed of sound into the subsonic stream and is the place of formation a jump when passing through a direct shock wave into a subsonic flow in an expanding nozzle made in the form of an exhaust diffuser.
