Helicopter Noise Reduction
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 […]
Rotorcraft Noise Modeling for Urban Air Mobility
Currently, there are no FAA-approved software tools suited to accurately model helicopter source noise [1]. An increase in helicopter manufacturing, the rise of the air-taxi, and an increase in vertiport construction, will drive a scarcity of airspace in cities, thus requiring more accurate noise analysis reporting. A tool tailored to the specific source noise of […]
Blast Mitigation for Rocket Launch
When a solid grain rocket first kicks on there is a huge one-time boom that propagates spherically outward like an explosion. This blast wave can damage expensive launch pad equipment or, even worse, disrupt the launch. This is what the pressure field looks like over a few milliseconds: This phenomenon is called Ignition Over-Pressure (IOP). […]
