At the AIAA Region III Student Conference on April 1, a new addition to the François Xavier Bagnoud atrium was unveiled: a Rolls-Royce M250 Engine.

First flown in 1961, the M250 engine has been installed on more than 170 different aircraft types, ranging from military and civil helicopters to unmanned US Navy surveillance helicopters.

The engine is on-loan from the archives of the Rolls-Royce Allison Heritage Trust Museum in Indianapolis, Indiana. Rolls-Royce’s increasing collaboration with the U-M Aero Department has been spearheaded by U-M alumna (BSME ’83) Kathryn Elliot, Chief of System Performance and Operability at Rolls-Royce, and Daniel T. Jensen, Head of Engineering for Services. The engine was presented by Rolls-Royce engineer and U-M Aero alum Ben Harter (BSAE ’05). At the unveiling, Aerospace Chair Dan Inman noted:

“[In the Aerospace Department], we try to solidify the applications of our theory courses through labs and other hands-on work. It is always wonderful to have a great piece of hardware [on display] to inspire our students and faculty alike.”

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
