Abstract
Guided and smart ammunitions are getting interest in the last decades. This paper aims to obtain the time history of control surfaces deflections of a subsonic guided gliding flying body using an inverse dynamics technique in vertical plane motion. This flying body has a standoff capability and designed to attack fixed targets. A 2D trajectory is designed to achieve two requirements. The first is to achieve the maximum range during glide phase subjected to maximum available angle of attack. The second is to achieve the maximum impact angle and impact velocity during terminal phase subjected to maximum available pitch deflection angle. Then a three degree of freedom inverse simulation is performed to obtain the deflection angles time history along the generated trajectory trajectory. Finally, a three degree of freedom direct simulation is performed using these deflection angles. Comparing the inverse and direct trajectories validates the inverse simulation equations, methodology, and results where the difference between the two trajectories time history data can be neglected. � 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.
