  • Method of positioning an aircraft jet engine noise suppressor in a convergent jet engine nozzle
    Patent number: 4720901
    Abstract: A combination convergent jet engine aircraft nozzle (86, 142, 146) and a ventilation tube (88, 136, 144) are fixed in place and have no moving parts. Ambient air is entrained through duct inlets (96, 140, 154, 160), through the nozzle walls, through hollow struts (90, 138), the struts supporting and being connected to a hollow central tube (102, 144) or a plurality of tubes (136), to adjacent the downstream end of the nozzle to mix at takeoff with the jet forming gas exhaust. The ducts (102, 136, 144) are positioned with respect to the nozzle exhaust so that entrained ambient air flows into the gas exhaust during takeoff and so that the ambient air flow is substantially restricted or shut off during cruise flight.
    Type: Grant
    Filed: November 12, 1985
    Date of Patent: January 26, 1988
    Assignee: The Boeing Company
    Inventors: Joseph M. Johnson, Russell L. Thornock
