Advancements in propulsion system performance are reliant on improvements in propulsive efficiency, through increases in turbofan bypass ratio. This requires larger nacelle diameters, which incur external aerodynamic ...
Engine fleet management has always been one of the most challenging tasks in any airline as it requires assuring reliability and cost effectiveness of engine operation at all times. The engine maintenance expenses are quite ...
To achieve ambitious future environmental targets for aircraft set out by organisations such as NASA and the European Union, turboelectric distributed propulsion (TeDP) has been proposed as a novel concept that has the ...
High altitude long endurance (HALE) unmanned aerial vehicles (UAV) could serve
as a platform to promote disruptive aircraft technologies in addition to set the stage
to sustain week-long flights with electronic equipment. ...
A turbofan engine fying through adverse weather conditions will experience a change
in its performance. One of the most common examples of these hostile conditions
is the case of ice crystals ingestion. Identifying these ...
Growing concerns about the rising costs of fuel as well as environmental issues have led to multiple innovative and futuristic aircraft concepts to tackle these issues. Turboelectric Distributed Propulsion (TeDP) and ...
Modern gas turbines are featured with cooling air systems that allow them to operate at temperatures much higher than the melting points of most of their hot gas path components. When these systems degrade, creep life ...
