Moshman Research is developing a new technique for aero-acoustic noise suppression that we believe can have a dramatic reduction on a helicopter’s main rotor blade noise. This could reduce noise in cities and open up precious airspace as well as reduce the warning time for military rotorcraft. We are seeking partners and investors in this technology. The video below was made using our HAM tool.
