Russian reusable engines will ensure rockets return to earth
Russian scientists and engineers are developing new reusable rocket engines. Pavel Chupin, general designer of ODK-Kuznetsov, told Izvestia in an interview.
"Of the new projects, preliminary design of engines of the first and second stages, operating on oxygen-kerosene vapor, for the newest ultra-light launch vehicle is now underway. Their thrust in various conditions will be 3-4 tons-force. It is assumed that the reusable Russian engines will safely return the rocket stages to the ground," he said.
According to the designer, during each flight the engines will be able to perform several activations, which is achieved due to the technology when ignition of the fuel mixture is performed using either reusable pyros or an electric ignition system. This distinguishes the development from traditional solutions that use single-action pyrotechnics.
The thrust vector will be controlled by electric actuators. This will make it possible to change the position of the engine nozzle relative to the axis of the rocket and thereby correct its trajectory.
At the same time, the engine control system will make it possible to change the thrust in a wide range according to signals from the control system of the launch vehicle. Together, all these rocket engine systems provide a wide range of maneuvering and reusable capabilities.
The work is being carried out in the interests of a commercial customer, Chupin specified.
