Method to Develop a Control System for a Stable and Guidable Hybrid Projectile

A Hybrid Projectile (HP) is a munition that transforms into an unmanned aerial vehicle (UAV) after being launched from a tube. In many situations it is desirable for this type of projectile to change its point of impact and depart from its current ballistic trajectory similar to a UAV following a path. A method was created to utilize deflectable control surfaces in conjunction with a guidance system to ensure the HP was statically and dynamically stable and to maneuver the HP to a desired point of impact. Methods were devised to control heading and pitch using vertical and horizontal tail surfaces. Testing and tuning these control methods were done using the Six Degree of Freedom (6DoF) system in Simulink. A cruciform tail section was utilized so that the HP could be statically and dynamically stable. The simulation showed that the method devised was able to guide a 40 mm HP up to 6250 projectile diameters off of the line of fire and increase range by 25.8% while landing within 125 projectile diameters of the desired impact point.
