Abstract

894,298. Jet propulsion nozzles. BOEING AIRPLANE CO. Aug. 12, 1958 [Aug. 19, 1957], No. 25894/58. Class 110 (3). A jet propulsion engine noise suppression nozzle comprises a plurality of nozzle discharge orifice tubes grouped in concentric circular clusters about a longitudinal central axis, the tubes in each circular cluster terminating in discharge orifices of substantially round crosssection lying in the same transverse plane, the inner circular series of circular orifice tubes being of smaller cross-section than those in the outer series. The nozzle 10 comprises a frustoconical base 14 which forms a pressure-chamber 12b and a support for the nozzle tubes. The nozzle tubes consist of an outer circular series of tubes 16, an inner circular series of tubes 18 and an inner central tube 20, and all the tubes terminate in substantially the same transverse plane. The tubes 16, 18 have convergentdivergent terminal nozzles. The turbine exhaust core 22 may extend through the tube 20 to create a convergent-divergent nozzle. An outer cowl 24 terminates in approximately the same plane as the nozzle tubes.
