We take it upon ourselves to make the engine optimized for whatever the pilot wants.” GE is now testing the engine’s core components and plans to run a full test in the middle of 2013.

Variable cycle engine design embodies a transformative approach in aero‐propulsion, enabling engines to adapt their thermodynamic cycle to meet diverse operational demands, from fuel efficiency ...

A new type of variable-stroke engine, or compressor, is presented in this paper. The stroke is adjusted by changing the length of the ground link using an auxiliary mechanism. Adjusting the ground ...

Unlike traditional engines with fixed airflow, the GE ACE is a variable cycle engine that will automatically alternate between a high-thrust mode for maximum power and a high-efficiency mode for ...

Pinnacle Engines in the US has just unveiled its latest plans for an opposed-piston engine that uses variable cycle combustion. The engine promises to bring superior fuel economy and efficiency to ...

That’s right, your prayers have been answered: Someone in Silicon Valley is finally developing an opposed-piston, sleeve-valve, variable-cycle engine for passenger-car use. Yeah, OK, we weren ...

Rolls-Royce is also working with Lockheed Martin and NASA to develop a variable cycle engine that could be used on supersonic transport aircraft. The company is working on a three stream nozzle as ...

Imagine a reliable, efficient 2.0-liter engine generating as much power as a 3.0-liter? Long live the gasoline engine! That's why Nissan's Variable Compression-Turbo (VC-T) engine is such a big deal.

It just has a variable compression ratio system and two-stroke operating cycle with direct fuel injection that allows it to increase fuel efficiency for sustainable alcohol based fuels.

If it has flown, the Chinese variable cycle engine could be combined with Professor Wang’s scramjet to form the holy grail of hypersonic flight, a combined turbine/scramjet engine.

The Adaptive Engine Transition Program aims to transform the performance of jet engines by designing and testing multiple 45,000-pound-thrust turbofan engine prototypes. The program’s goal is to ...
