An analytic investigation has been made of the pressure distribution on a plane ground surface under an aircraft flying at low altitude with subsonic velocity. The effects of the volume and the lift of the aircraft on the pressure distribution have been considered. The aircraft volume has been represented by an ovoid and the lift by a vortex of constant strength and two trailing tip vortices. The volume and lift components of this pressure distribution have furthermore been expanded in power series in the ratios of the aircraft dimensions to the flight altitude. As a numerical example, a fighter aircraft, flying at the Mach numbers 0.8, 0.9 and 0.97 and at the altitudes 25, 50, 100 and 200 meters, has been considered. (Author)
