Device for assisting solid propellant propulsion system of single shot helicopter, single shot helicopter equipped with such device

摘要

The present invention is an apparatus for assisting a single helicopter propulsion system, comprising an engine coupled to a power transmission gearbox (15) suitable for rotating a helicopter rotor (88), A turbine (18) that rotationally drives an output shaft (34) mechanically connected to a power transmission gearbox (15), and the turbine (18) transmits power from a pressurized fluid to the output shaft (34). And a controlled means (16) for supplying the pressurized fluid to the drive turbine (18) so as to allow it to be converted into mechanical power for rotation.
