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 ...

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. ...

This work describes the outcome of research program investigating thrust measurements in enclosed test facility for modern aero gas turbine engines. Literature work, experimental work and a description of Computational ...

Radical aircraft and propulsion system architecture changes may be required to continue historic performance improvement rates as current civil aircraft and engine technologies mature. Significant fuel-burn savings are ...

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 ...

Aeroderivative gas turbines are used all over the world for different applications as Combined Heat and Power (CHP), Oil and Gas, ship propulsion and others. They combine flexibility with high efficiencies, low weight ...

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 ...

The Blended-Wing-Body is a conceptual aircraft design with rear-mounted, over wing engines. Turboelectric distributed propulsion system with boundary layer ingestion has been considered for this aircraft. It uses electricity ...
