Research projects aimed at making supersonic air travel a commercial reality are to benefit from a further $2.3m of funding from NASA.
The US body has selected eight studies examining how to reduce the environmental and noise impacts of supersonic flight.
Projects that have won support include: MIT’s research into the global environmental impact of "supersonic cruise aircraft in the stratosphere”; and Wyle Laboratories' investigation of the influence of turbulence on shaped sonic booms.
OEMs Honeywell, GE and Rockwell Collins have also been awarded funds. Honeywell is researching pilot interface for mitigating sonic booms, while GE is examining low-noise integration concepts and propulsion technologies for future supersonic civil aircraft.
