초록

A missile, either a powered missile or an unpowered projectile, includes a freely-rolling tail assembly having an odd number of fins. Having an odd number of fins may reduce oscillations caused by the rotation of the freely-rotating tail. This may make a more stable platform for a seeker, such as an uncooled focal point array or other imaging infrared (IIR) or millimeter wave radio frequency (MMW) seeker, in the body of the missile. Also, minimizing oscillation by using an odd number of fins may facilitate control of the missile.

청구항

1. A guided missile comprising:a body; and a tail assembly coupled to the body; wherein at least part of the tail assembly is freely rotatable as a unit about a central longitudinal axis of the missile, such that the at least part of the tail assembly rotates unpowered and uncontrolled, relative to the body; wherein the tail assembly has an odd number of substantially planar fins; wherein the at least part of the tail assembly includes the fins; and wherein the substantially planar fins are substantially co-planar with an axis of the at least part of the...
