Mach Wave Elimination
A new method for quieting high-speed jets
(U.S. Patents 5590520 and 5916127)
data for Targeted Mach Wave Elimination (TMWE)
This section presents selected data from the acoustic experiments on TMWE. The jet Mach number is 1.5 and its velocity is 700 m/s. The coflow is supplied at conditions simulating the unheated exhaust of fan at pressure ratio 1.9; its Mach number is 0.95 and velocity is 360 m/s.
