ABSTRACT:
The compact structural assembly comprises a gas generator, and two turbopumps for feeding the combustion chamber of a chamber of a rocket engine with propellants. A main structure which is essentially circularly symmetrical about the axes of rotation of the turbopumps and made of thermostructural composite materials surrounds the turbines and fixes together the body of the gas generator and the pump bodies of the turbopumps. Internal partitioning elements added to the main structure and likewise made of thermo-structural composite materials serve to divide the space inside the main structure into a plurality of intercommunicating cavities allowing hot gases from the gas generator to flow to the turbines, and also serving to collect the outlet gases from the turbines and exhaust them through a common exhaust duct.
