US scientists master control of hypersonic jet engine with light-based tech
The research allows operators to control airflow at the speed of light when a ‘shock train’ occurs in hypersonic jet engines.
The finding can lead to more efficient stabilization of hypersonic jet aircraft, according to the study carried out by the researchers at the University of Virginia, School of Engineering and Applied Science. The tool analyzes the amount of light emitted by a source — in this case, the reacting gases within the scramjet combustor — as well as other factors, such as the flame’s location and spectral content. The wind tunnel test, in fact, was the world’s first proof that adaptive control in these types of dual-function engines can be achieved with optical sensors, the release stated.
