This book was released on 1953 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theories for the free fligbt motion of miseiles, as generally considered by the aerodynamicist and the ballistician, are combined to yield a single theory for the basically symmetrical missile. The force and moment system contains not only the usual aerodynamic forces and moments but also the effects of slight configurational asymmetries and the effects of rolling velocity. The theory yields the condition for the dynamic stability of both statically stable and statically unstable missiles, and alco predicts that the presence of configurational asynnetries together with rolling velocity may result in resonance instability. Numerical integrations of the differential equations for the pitching and yawing motion are carried cut for three variations in the rolling motion. The results indicate that the rapidity of passage through the resonance region is a significant factor affecting the nagnitude of the pitch and yaw of the missile. rWo models of a simple arrow type missile having control surface deflection are gun launched at supersonic velocity in the Aberdeen Spark Photography Range and the free flight pitching and yawing motion and the transverse displacement are measured. The tricyclic theory is fitted to the experimental data. The results indicate tbat the theory accurately represent. the actual motion of the two models and that the associated static and dynamic aerodyamic derivatives are accurately determined.

Available in PDF, EPUB and Kindle. Book excerpt: The quasi-linear analysis which has been successfully applied to the nonlinear angular motion of symmetric missiles is extended to include the nonlinear motion of slightly asymmetric missiles. This analysis indicates the existence of three special spin rates - zero spin, resonant spin, and approximately three times resonant spin. The exact solution for the small amplitude motion about a large trim angle of a nonspinning missile with a cubic static moment is obtained and the quasi-linear relations are shown to agree well with this exact result. Relations for a cubic damping moment and a cubic lift force are derived. (Author).

Book excerpt: Even the earliest weapon developers faced the need to understand how and why guns and ammunition work in order to improve their effectiveness. As weapons became more sophisticated, the field of ballistics naturally divided into three main areas of specialization: interior, exterior, and terminal ballistics. Providing unique coverage of all three ar

This book was released on 1961 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis includes nonconstant spin rates and inertias and considers the effects of time-varying thrust misalinements, mass unbalance, and jet damping. The method was developed for bodies having small transverse angular velocities. Results are presented in the form of equations for space-referenced Euler angles, flight-path angles, body-referenced attitude rates, and earth-referenced vehicle-trajectory coordinates. Also, equations for maximum wobble have been derived for certain input conditions. Comparisons with numerical solutions are included for two sample problems.

Available in PDF, EPUB and Kindle. Book excerpt: The aeroballistic aspects of a semipassive roll-control system for nominally symmetrical reentry vehicles are discussed. The system consists of an impeller attached to the base of the vehicle, with fins so oriented that their reaction to the radial component of flow in the recirculation zone produces a rolling moment.
