The Effects of Wind and Temperature Gradients on Sonic Boom Corridors

Abstract

Calculation of sonic boom corridor widths based on closed form solutions of ray acoustic equations using piecewise linear atmospheric models of winds and temperatures has been accomplished. Detailed solutions of ray tracing equations are presented for all possible variations of winds and temperatures, within the framework of the assumed model atmosphere. The effects of aircraft flight altitude and Mach number, wind and temperature gradients, and wind direction on sonic boom corridor are investigated in detail, including the effects of non-standard atmospheres such as prevail in winter months. Numerical results are presented and amply discussed. Agreement of the present calculations with published data is excellent.
