Claims (2)

1. Способ внутреннего охлаждения двухкомпонентного жидкостного ракетного двигателя малой тяги, заключающийся в подаче основной части компонентов топлива в ядро потока камеры сгорания и создании вблизи стенок камеры сгорания и сопла низкотемпературного пристеночного слоя путем подачи одного из компонентов топлива на стенку, отличающийся тем, что контролируют температуру стенки камеры сгорания в заданной точке и компонент топлива на стенку подают только по достижении в контролируемой точке стенки предельной заданной температуры и прекращают подачу компонента при снижении температуры ниже заданной или при выключении двигателя.1. The method of internal cooling of a two-component liquid propellant small thrust rocket engine, which consists in supplying the main part of the fuel components to the core of the combustion chamber flow and creating a low-temperature wall layer near the walls of the combustion chamber and nozzle by supplying one of the fuel components to the wall, characterized in that the temperature is controlled the walls of the combustion chamber at a given point and the fuel component is supplied to the wall only after reaching the maximum temperature and at they cut the component supply when the temperature drops below the set value or when the engine is turned off. 2. Жидкостный ракетный двигатель малой тяги, содержащий корпус камеры со смесительной головкой, магистрали подачи компонентов топлива с клапанами подачи и форсуночные элементы для формирования ядра потока, и форсуночные элементы пристеночной завесы, отличающийся тем, что форсуночные элементы пристеночной завесы сообщены с магистралью подачи одного из компонентов топлива через дополнительный клапан подачи, управляемый по командам блока управления, подключенного к датчику температуры, установленному в контролируемой точке корпуса камеры.2. A liquid propellant small thrust engine comprising a chamber body with a mixing head, fuel component supply lines with feed valves and nozzle elements for forming a flow core, and nozzle elements of the wall curtain, characterized in that the nozzle elements of the wall curtain are in communication with the feed line of one of fuel components through an additional supply valve, controlled by commands of a control unit connected to a temperature sensor installed at a controlled point on the camera body Era.
