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.
Download or read book Flight Motion of a Continuously Elastic Finned Missile written by Charles H. Murphy and published by . This book was released on 2002-06-01 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motion of elastic finned projectiles has been analyzed by various approximate theories. In this report the exact equations of small amplitude motion are derived for a symmetric missile. The aerodynamic and elastic symmetries are used to allow the use of complex variables to describe the lateral motion in a non-rotating coordinate system. Although the resulting equations are both ordinary and partial differential equations, frequencies and damping rates of free oscillations are obtained from an ordinary differential equation with boundary conditions. Equations for a permanently deformed bent missile are derived, and an ordinary differential equation for the forced motion of a bent missile is obtained. Sample calculations for a finned projectile with a fineness ratio of 20 show resonant motion at the aerodynamic frequency as well as at each elastic frequency. The nonlinear roll moment associated with a bent missile is computed and the location of possible spin-yaw lock-in is determined. The flight motion of an elastic missile is shown to be the sum of two elliptical motions: a low frequency pitching motion and a higher frequency flexing motion. The induced drag coefficients for both motions are computed as functions of the missile's elasticity.
Download or read book Missile Flight Simulation written by Jeffrey Strickland and published by Lulu.com. This book was released on 2015 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: A missile flight simulation is a computational tool that calculates the flight of a missile from launch until it engages the target. The simulation is based on mathematical models of the missile, target and environment. This book provides instruction for the preparation of these mathematical models to simulate the flight of a surface-to-air missile. The 2nd Edition of Missile Flight Simulation provides updated simulation processes using MATLAB(R) and Simulink(TM), while improving and clarifying previous content. The book may be used as a reference or as a textbook, although it is devoid of exercises. However, the reader is encouraged to perform the simulation of Charter 12 using MATLAB(R) and Simulink(TM), or a programming language such as FORTRAN (see Chapter 10). The book is not intended to be a missile flight engineering reference and does not contain every aspect of missile flight. It provides the appropriate content for simulating missile flight from launch to terminus only.

Available in PDF, EPUB and Kindle. Book excerpt: The linearized angular motion of a symmetric missile is developed in some detail with some consideration of the rolling motion, drag, aerodynamic jump and the effect of varying coefficients. The tricyclic motion of a missile with misaligned control surfaces in briefly considered. This linear theory is, then, applied to the analysis of ballistic range data. Next, simple cubic nonlinearities in static moment and Magnus moment are treated by a quasi-linear analysis and these cubic coefficients obtained from ballistic range flight data. More generalized relations for arbitrary symmetric nonlinear terms are derived and their use in the construction of "amplitude" planes indicated. These amplitude planes have proven to be quite useful for the prediction of missile flight performance. Finally, the influence of strongly nonlinear static moments is determined by a perturbation method which makes use of two quasi-constants of the motion--total energy and angular momentum.
