Summary

The types of pitch/yaw coupling which may result from roll motion of a conventional tail-controlled cartesian missile have been categorised. The consequences of the couplings upon:

  1. (a) the response to a step demand for manoeuvre, and

  2. (b) the decay of error in a beam-rider system are presented.

Potentially the most damaging forms of coupling are due to

  1. (a) mis-match of the Invariant Frames of airframe and servos,

  2. (b) angular mismatch between parts of the system, and

  3. (c) gyroscopic coupling.
