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 varies are rotatably coupled to ...
This can impair the off-design performance of the engine and lead to compromises during engine design and to operability limitations. Taking the power off the low-pressure (LP) spool mitigates some of the problems but has other limitations. In this work, all alternative novel turbofan ...
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 ...
With a two-shaft engine, the accessory drive gearbox () for the operation of a generator and other auxiliaries () is connected to the high-pressure shaft (... G Venter 被引量: 0发表: 2008年 Dual Drive Booster for a Two-Spool Turbofan: High Shaft Power Offtake Capability for MEA and ...
A high bypass turbofan engine operated at cruise is selected for this evaluation and the simulation was performed using the Gas Turbine Simulation Program (GSP). The affected components considered are turbines and compressors with deterioration rate ranging from 0% to 5%. The effect of selected ...
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 ...
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)....
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 ...
