LPV MODELING OF A TURBOFAN ENGINE
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2005Abstract This article describes the application of quasi-LPV modeling techniques to an industrial military turbofan engine simulator developed by Snecma Moteurs, the French aerospace propulsion company. Two approaches are used, classical Jacobian linearization and velocity based linearization. First, we present briefly the theoretical aspects of both

In the last chapter, the turbojet engine was discussed in detail. Historically, commercial aviation began toward the end of World War II with propeller-driven planes. It soon became apparent that the flight speeds of the propeller planes were limited to low subsonic values. The use of the gas turbine engine in combination with a propulsion nozzle, i.e.,

PROGRESS in the development of turbofan engines for civil and military applications has enabled requirements from around 5,000lb to over 70,000lb thrust to be satisfied or anticipated, with prospects for this range to be extended. The three major powerplant manufacturers (Rolls‐Royce, General Electric and Pratt & Whitney) are engaged in fiercely ...

Looking into the future of aviation for commercial aircrafts there are various viable options for engine and associated propulsion technologies. The team had to eliminate some of the possible solutions. Superconducting electric motors were alleviated considering weight factors and lack of technology readiness to fly long range commercial jets.

The Emergence of the Turbofan Engine
2000If you have looked out the window of an airplane lately, you may have noticed that jet engines are gradually getting shorter and fatter. You will see 737s, the most common airliner in service, with two types of engines of distinctly different shapes. The older models have long, stovepipe-shaped engines under the wings, where the newer ones (or older ...
