Unsteady flow characteristic analysis of turbine based combined cycle (TBCC) inlet mode transition
Propulsion and Power Research, 2015 A turbine based combined cycle (TBCC) propulsion system uses a turbine-based engine to accelerate the vehicle from takeoff to the mode transition flight condition, at which point, the propulsion system performs a “mode transition” from the turbine to ...

Investigation of the stall-induced shock wave (hammershock) at the inlet to the engine [PDF]
The peak static pressures measured at the inlet to the engine during stall are presented for a turbojet and two turbofan engines. It is shown for one turbofan and the turbojet that the static pressure ratio across the hammershock does not exceed ...

Turbojet Engines - Progressive Methods of Modeling
Acta Mechanica Slovaca, 2009 Small turbojet engines represent a special class of turbine driven engines. They are suitable for scientific purposes and research of certain thermodynamic processes ongoing in turbojet engines. Moreover such engines can be used for research in the area of alternative fuels and new methods of digital control and measurement. Our research, which is also
