Available in PDF, EPUB and Kindle. Book excerpt: Dynamic instabilities observed for symmetric missiles and projectiles arise from a large variety of causes. These include unstable linear damping moments, and different nonlinear in-plane and out-of-plane damping moments for non spinning re-entry vehicles, nonlinear Magnus moments for spinning missiles, and internal resonance with moving payload components. If aerodynamic trim is present, linear spin-yaw resonance can occur as well as nonlinear subharmonic motions and a number of other limit motions. This report gives a complete survey of these possibilities with a number of actual case histories.

This book was released on 1971 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of aerodynamic damping coefficients nonlinear with angular velocity on the dynamic stability of statically stable configurations of symmetric missiles are investigated analytically and verified via numerical simulations. In particular, the simplest mode of oscillation, single degree of freedom pitching motion, is considered including a restoring moment nonlinear with angle of attack and a damping moment nonlinear with both angle of attack and angular velocity. Averaging methods are used to obtain an approximate expression for the frequency and amplitude variations with time. It is noted that the internal mass distribution (moment of inertia) can be a critical factor in the interpretation of dynamic stability characteristics from single degree of freedom wind tunnel tests, especially when employing light-weight models.

Download or read book Flight Mechanics of an Elastic Symmetric Missile written by Charles H. Murphy and published by . This book was released on 2000-04-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The free-flight motion of an elastic missile is approximated with three bodies connected by two massless elastic cantilever beams. If the mass distribution of the three bodies is 1-2-1, the frequency of the symmetric oscillation of the outer bodies is within 5% of the classical frequency of the oscillation of a free-free beam. A second combined pitching antisymmetric flexing motion can occur with a frequency that is almost twice that of the symmetric flexing motion. As the beam stiffness is reduced, the symmetric flexing motion frequency approaches the rigid body aerodynamic zero-spin frequency, and the flight zero-spin aerodynamic frequency is considerably reduced. Moderate beam damping can cause dynamic instability for spins greater than the zero-spin aerodynamic frequency. Resonance mode amplification can occur when the spin is equal to the zero-spin aerodynamic frequency, but more importantly it can occur when the spin is equal to the two elastic flexing frequencies. Spin-yaw lock-in occurs at the lower elastic frequency.

Available in PDF, EPUB and Kindle. Book excerpt: A dynamic derivative sensitivity study was conducted to demonstrate the importance of dynamic derivatives in missile motion simulation studies. Generalized bank-to-turn and yaw-to-turn missile configurations were used with a six-degree-of-freedom linearized stability program. The effects of various dynamic derivatives on missile stability were investigated in both level and turning flight for several Mach numbers and altitude conditions.
