Robust monitoring of turbofan sensors

2014 IEEE Aerospace Conference, 2014
Bench development tests of new turbofan engines make an important use of sensor measurements to help engineers understand the behavior of new components design. Such tests are expensive and may be completely compromised if any measurement is missing.

Variable Bypass Turbofan

2013
This study was conducted to investigate the effect of a variable bypass on the operation and performance of a turbofan engine. The goal was to establish the viability of such an engine, in the context of being able to provide an aircraft, so equipped, with variable performance that could be altered to suit different operational scenarios.

Large turbofans to the year 2000

The Aeronautical Journal, 1984
The recognition of the political importance of energy supply, inefficient energy usage and its adverse ecological impact combined to produce rapidly inflating energy prices which in turn contributed to an industrial slump. With this platform of a decade of uncertainty, predicting future requirements is, to say the least, somewhat problematical.

Windmilling of turbofan engine; calculation of performance characteristics of a turbofan engine under windmilling

2014
The turbofan is a type of air breathing jet engine that finds wide use in aircraft propulsion. During the normal operation of a turbofan engine installed in aircraft, the combustor is supplied with fuel, flow to the combustor is cut off and the engine runs under so called Windmilling conditions being driven only by the ram pressure ratio by producing ...
