Papamoschou states that if air is separated in channels of different speeds, noise can be driven away from ground. This technique supported by the U.S. National Aeronautics and Space Administration reduces noise by up to six de...
He makes engines that glow at around 1500 degrees Fahrenheit, produce about as many decibels as Top Fuel dragsters, and launch him toward the horizon at crazy-fun speeds. He once built the world’s largest pulse-jet engine and mounted it in a 1965 Jaguar. Star Wars audio engineers ...
A 3-decibel reduction in total sound power was found for the 100:1 slot nozzle. Addition of the jet flap further reduced the total sound power generated by approximately 1.5 decibels for a total of nearly 5 decibels. The largest reductions resulting from the flap occurred between 60° and ...
