What are Ceramic Matrix Composites? Composite materials typically consist of two components: a reinforcement part to provide mechanical strength and a matrix material that holds all the components ...

Rolls-Royce will shortly begin rig tests of a clean-sheet small gas turbine engine that has been specifically developed as part of a new turbogenerator being developed for the advanced air mobility ...

Pre-swirl systems are a critical component in modern gas turbine engines, designed to condition the cooling airflow before it reaches the turbine rotor blades. By imparting a controlled rotational ...

The engine is the lifeblood of a car. It converts fuel, usually gasoline, into physical motion that turns the wheels and makes the vehicles go. Over the years, as technology advanced, so too did ...

The Greek power system provides an interesting energy transition case study. Lignite, the lowest-ranked coal in terms of heat content, was for many years the leading source of power generation in ...

Rolls-Royce has completed the first fuel burn on a new small gas turbine engine it is developing as part of a lightweight turbogenerator for hybrid-electric aircraft applications. Performed at the ...

When the Army launched the M1 tank program in the early 1970s, it was determined to avoid the cost overruns and failures that plagued earlier efforts like the MBT-70 and XM-803. This time, the Army ...
