Low Pressure Compressor Variable Vane Control for Two-Spool Turbofan or Turboprop EngineA system and a method for adjusting an angle of at least one stator vane of a low pressure compressor (LPC) of a two spool gas turbine engine is disclosed. Variable stator vanes are rotatably coupled to ...
The CFM56-7B is a high bypass ratio, a two-spool, axial flow turbofan engine.A.CFM56-
More specifically, a brief architectural and functional description of a two-spool commercial turbofan aero-engine shall be given, in order to justify the structure of the developed network DEA model, along with the implemented inputs, intermediate Non-parametric post-hoc analysis The theoretical ...
When the aircraft is in flight, the cowlings are closed and are shaped such as to provide aerodynamic continuity for the engine as a whole. More specifically, the nacelles for twin-spool turbofan engines are equipped with at least a pair of fan cowlings, respectively on the right hand ...
Yet another development includes the "Water-Augmented-Gas-Jet" as described in U.S. Pat. No. 3,808,804 to Scott-Scott in which a propulsion unit includes a gas breathing turbofan engine, incorporating a mist booster unit in the exhaust duct, fed through water injectors, pipe lines and wat...

The prediction of the behaviour of a two-spool turbofan engine (Tay Mk610) under steady-running and during transient performances has been carried out in the present investigation. Four different variable geometry features have been investigated with a view to achieving surge-free acceleration and ...
A simplified, low order state-space approach for dynamic modelling of a twin spool turbofan gas turbine engine is proposed and investigated. The governing equations constituting the dynamic model of the engine are derived analytically by considering 1D mass, moment and energy balance equations at ...
The component characteristics extrapolation method based on the relationship between flow coefficient and adiabatic pressure head coefficient in low speed region was researched, and the starting process control law of some two-spool turbofan was designed using the Virtual Power Extraction Method (VPEM)....
This paper presents an application of Genetic Algorithm (GA) metaheuristics\nto optimise the design of two-spool turbofan engines based on exergy and energy\ntheories. The GA is used to seek the optimal values of eight parameters that\ndefine the turbofan engine. These parameters are encoded as...
