Multiobjective Optimization for Turbofan Engine Using Gradient-Free Method
IEEE Transactions on Systems, Man, and Cybernetics: SystemsTurbofan engine performance optimization is usually formulated as a single objective, closed-form optimization problem by employing a prior mechanism model with an additive, user-preference weight. However, in practical scenarios, the conventional single

Design and verification of a turbofan swirl augmentor
14th Joint Propulsion Conference, 1978The paper discusses the details of the design and verification testing of a full-scale turbofan 'swirl' augmentor at sea level and altitude. No flameholders are required in the swirl augmentor since the radial motion of the hot pilot gases and subsequent combustion products provides a continuous ignition front across the stream.

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 ...

Digital Control Brings Large Turbofan Benefits to the Regional Jetliner Turbofan Market
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; General, 1994In keeping with the general industry trend of applying Full Authority Digital Electronic Control (FADEC) technology to small gas turbine engines, Textron Lycoming and Chandler Evans Division of Coltec Industries have developed and qualified a single channel control system for use on the Textron Lycoming LF507-1F turbofan engine.

Volume 1: Turbo Expo 2005, 2005
Smaller smarter un-manned air vehicles (UAV’s) and missiles are being proposed and developed to function in a variety of roles previously performed by larger manned aircraft and limited range missiles. The endurance and stealth demanded of such advanced vehicles requires small turbofan engines possessing relatively higher power density combined with ...
