Spinning Projectile Instability Induced by an Internal Mass Mounted on an ElasticBeam

摘要

The steady-state motion of a loose internal component can cause flightinstabilities. In previous work, these instabilities have been predicted in terms of the amplitude and phase of the component motion. In this report, for the case of a component mounted on an elastic beam, the amplitude and phase of the motion are predicted in terms of the beam characteristics and the component's mass properties. Thus, flight stability can be computed from design parameters. (MM).
