Abstract : Sonic booms generate an N-type pressure wave. Equations and tables are presented for the calculation of peak overpressure for the sonic boom generated by aircraft in straight level flight. An equation is also furnished for the calculation of the time duration of the sonic boom pressure wave. Aircraft maneuvers, ground terrain, and meteorological conditions affect the peak overpressure of the pressure wave. Corrections for these effects can only be roughly estimated. Dynamic load factors for the pressure waves of sonic booms are presented. These factors may be used to calculate the dynamic deflection and stress caused by a sonic boom. Sample calculations of dynamic deflection and stress for a beam, plate, and roof truss are found in Appendixes 3, 4, and 5 respectively. (Author)
