Abstract

633,935. Propulsion nozzles for aircraft. WESTINGHOUSE, ELECTRIC INTERNATIONAL CO. Jan. 29, 1948, No. 2693. Convention date, Feb. 19, 1947. Drawings to Specification. [Class 110(iii)] A propulsion jet nozzle is convergentdivergent and such that for the lower portion of the thrust range the effective discharge area is greater than the throat area and for the upper part of the thrust range the discharge area decreases with increasing speed to become equal to the throat area. The ratio of exit area to throat area is equal to or larger than the theoretically optimum area ratio of a convergent-divergent nozzle. The nozzle provides for a maximum Mach number less than 1.3.
