초록

A 2-D correction system uses intermittent deployment of aerodynamic surfaces to control a spin or fin stabilized projectile in flight; correcting both crossrange and downrange impact errors. Intermittent surface deployment develops rotational moments, which create body lift that nudge the projectile in two-dimensions to correct the projectile in its ballistic trajectory. In low spin rate projectiles ("fin stabilized"), the rotational moment directly produces the body lift that moves the projectile. In high spin rate projectiles ("spin stabilized"), the ...

청구항

We claim: 1. A method for correcting the range and deflection errors in an unguided spin or fin stabilized spinning projectile, comprising: determining deviations of the spinning projectile from a desired ballistic trajectory in a downrange dimension and a crossrange dimension; and repeatedly deploying and stowing at least one aerodynamic surface on the spinning projectile forming partial roll cycles that develop a sequence of rotational moments, said spinning projectile's gyroscopic inertia reacting to said sequence of rotational moments to cause a pre...
