Abstract (en)

[origin: EP0071322A2] An axisymmetrical projectile having a specified design launch condition includes an axisymmetrical cavity 12 substantially filled with liquid, the cavity dimensions and liquid characteristics being so tuned that a main natural frequency of the liquid within the cavity approaches a nutation frequency of the projectile to cause resonance after a predetermined duration of flight following a design launch. The resonance increases the nutation amplitude causing a rapid rise in drag which quickly halts the projectile's flight.
