Low Altitude Technique for Meaurement of Stability Factors of Bombs

Abstract

For a bomb to be aimable it must be stable. Early in the development stage of new bombs, therefore, stability tests must be carried out. Previous notes 1,2 have dealt with the theory of stability and the motion of a bomb when recovering from disturbances, damped simple harmonic motion having been shown to be a usual component of the motion. This note describes the technique developed at the R.A.E. for studying the behaviour of bombs in disturbed flight and thereby obtaining a quantitative assessment of their stability. The tests are carried out full scale from low altitudes, and from the characteristics of the damped S.H.M. performed by the bomb, stability factors are obtained. Those factors are independent of the conditions of test and size of the bomb and can therefore be used directly to compare the stability of different types of bomb.
