J-85 jet engine noise measured in the ONERA S1 wind tunnel and extrapolated to far field [PDF]
Noise from a J-85 turbojet with a conical, convergent nozzle was measured in simulated flight in the ONERA S1 Wind Tunnel. Data are presented for several flight speeds up to 130 m/sec and for radiation angles of 40 to 160 degrees relative to the upstream
