1949


The effect of acceleration of elongated bodies of revolution upon the resistance in a compressible gas is investigated. It is assumed that the body produces only small disturbances in the flow so that the velocity potential satisfies the simple wave equation. The results of the analysis show that for accelerations not higher than 1000 meters per second (exp 2) and velocities comparable with the velocity of sound, the added pressures arising from the acceleration are negligibly small.
