Design Considerations for an Impulse Corrected, Body Fixed, Laser Guided, Fin Stabilized Rocket
Abstract
This report is an analysis of the dynamics and accuracy of a laser guided fin stabilized rocket. The guidance uses a quadrant detector, pursuit guidance, and is a body fixed system (no gyroscopic or relative wind reference). Corrections are made using short action time explosive strips located forward of the center of mass. Several guidance considerations which affect the accuracy or effectiveness of this system are analyzed in this report. Some of these considerations are: phasing of the laser pulse frequency and the pitch frequency; the relation between the trim misalignment, the pitch frequency, and the roll rate; the maximum expected correction as a function of the physical and aerodynamic characteristics of the rocket; target motion and wind; and the dead zone size.
