The view from inside supersonic combustion
on March 15, 2018 at 5:07 pm
In supersonic engines, achieving the right flow speed, producing the right ratio of evaporated fuel and causing ignition at the right time is complex. Vortices are affected by the shock wave, and this changes the way the fuel combusts and multiplies the number of possibilities of how particles can behave. To deepen our understanding, researchers use numerical modeling to calculate the huge variety of possible outcomes. […]
Holography approach improves heads up displays...

Heads-up displays are transparent devices used in airplanes and cars to provide information such as critical flight data or driving directions on the windshield. An innovative holography-based approach could soon make these heads-up displays much easier to see with a large eye box. […]
