DEVICE FOR TURNING A TURBOPUMPS DRIVING TURBINE FOR A ROCKET ENGINE OPERATING ON LIQUID FUEL

摘要

The device is used in rocket engines. It increases the powerof the engines. The device includes several stages is driven. Thegas turbine (14) of the first stage of driving by compressed airfrom a tank (4) and revolves turbopump (9) for fuel and turbopump(15) for oxidant. Another turbine (44) of the following stage isdriven by the combusted fuel mixture in a nozzle (18) and drivesturbines for fuel and for oxidant in that stage. Turbine (19) ofthe last stage is driven by the combusted fuel mixture in nozzle(45) by driving two turbopumps - for fuel and for oxidant whichpumps feed manifold (24). The fuel mixture burns in another nozzle(25) where the general traction of the whole driving system isformed.1 claim, 3 figures
