Free-flight Investigation of the Deployment, Dynamic Stability, and Control Characteristics of a 1/12-scale Dynamic Radio-controlled Model of a Large Booster and Parawing

Book Description
An investigation has been conducted to determine the deployment, dynamic stability, and control characteristics of a parawing-rocket booster model using a radio-controlled free-flight technique. The parawing utilized folded rigid members. The results show that this deployment technique provides consistent transitions from essentially vertical descent at subsonic speeds with the parawing stowed on the booster to normal trimmed gliding flight with the parawing deployed. For the particular deployment configuration selected, a small drogue parachute was needed to hold the parawing away from the booster during deployment until the parawing was developing lift properly. In general, the flight characteristics of the model were fairly satisfactory for an unmanned vehicle although the model had a small constant-amplitude Dutch roll oscillation and some undesirable characteristics at the stall. The model was controllable by center-of-gravity movement but the response of the model appeared to be sluggish.

A Comparison of Different Guidance Schemes for a Direct Fire Rocket with a Pulse Jet Control Mechanism

Book Description
Compared to gun launch ammunition, uncontrolled direct fire atmospheric rockets are terribly inaccurate, to the point where they are used most effectively on the battlefield as area weapons. Dispersion characteristics can be dramatically improved by outfitting the rocket with a suitable control mechanism and sensor suite. In the work reported here, a lateral pulse jet control mechanism is considered. The lateral pulse jet mechanism consists of a finite number of small thrusters spaced equally around the circumference of the rocket. Using a simulation model that includes projectile, flight control system, and inertial measurement unit dynamics, three different control laws are contrasted, namely, proportional navigation guidance, parabolic and proportional navigation guidance, and trajectory tracking control laws. When the number of individual pulse jets is small, a trajectory tracking control law provides superior dispersion reduction. However, as the number of pulse jets is increased, the relative performance of the parabolic and proportional navigation guidance control law is slightly better than the trajectory tracking control law. When the number of pulse jets is small, the proportional navigation guidance, as well as the parabolic and proportional navigation guidance control laws, exhibits large mean miss distance. All control laws appear to be equally susceptible to accelerometer and gyroscope errors that corrupt inertial measurement unit rocket state feedback.
