A New Type Flap Valve for Generating Sonic Booms in a Pyramidal Horn.
Abstract
A description is given of the design, operation and performance of a radically new type of sonic-boom generating flap-valve. Included are the ancillary cam, clutch, flywheel and electric motor system, as well as a much larger air reservoir than used previously. An updated and greatly extended analysis describes the time varying reservoir conditions (e.g., pressure) and mass-flow rate of air through the flap valve, as well as the wave motion or characteristics of the travelling N-wave in the pyramidal concrete horn (25 m long with a 3 m x 3 m base) of the UTIAS travelling-wave sonic-boom simulation facility.
