  "textContent": "The pre-combustion chamber for feeding a turbine in a liquid propellant rocket engine, providing energy for driving the fuel and oxidant pumps, according to the invention is a detonation chamber (1) in which - in a rotating detonation mode, the propellant mixture enriched in one of its components is continuously burned, the chamber being arranged coaxially with a turbine (3) and a power generator (5) that powers electric motors driving the fuel and oxidant pumps, and also with the outlet (4) of incomplete combustion products from the turbine (3) to the main combustion chamber of the rocket engine.In the rotating detonation process, a fuel and oxidant propellant mixture, preferably previously vaporized, is burned while having a fuel-rich composition or alternatively an oxidant-rich composition, whereas the structure and dimensions of the chamber - in a disc or a ring form, can be easily adapted to the spatial conditions within the rocket and/or rocket stage, as well as to the desired efficiency of fuel and oxidizer pumps, taking into account the needs of the rocket, space shuttle or satellite, and the combustion products from the detonation pre-combustion chamber (1), used to power the turbine (3) driving the power generator (5) providing a possibility to generate an electricity excess for optional powering other components, devices and systems of the rocket apart from powering the propellant components pumps.",
