Aerodynamical CFD Study of a Non-Lethal 12-Gauge Fin-Stabilized Projectile

WebTo research the dynamic stability of fixed canard dual-spin projectiles in full trajectory flight, the state space model of the complex attack angle motion is established under the condition of small attack angle, and the general condition that the real parts of the characteristic roots are all negative is derived by using the Hurwitz method. Based on the motion … WebMar 4, 2013 · A thorough yet practical procedure for the treatment of the preceding issues is described in this work involving several steps, such as nonlinear modeling of the projectile dynamics, equilibrium point computation, and linear parameter-varying modeling, autopilot design as well as guidance algorithms. Webtheory is used to simplify the highly nonlinear dynamic equations to a set of linear ordinary differential equations. More details on projectile linear theory can be found in McCoy (15). The linear equations developed by Costello and Peterson (14) neglected gravity, since their primary interest was dynamic stability, and also did not include ... building automation system tampa fl
