Symmetric Missile Dynamic Instabilities

Research of Influence of Small Asymmetries Construction on the Dynamics Motion of Space Landing Vehicle with Considering Resonance

“…-the projections of the angular velocity of the landing vehicle on the axis of the related coordinate system; Numerous studies of resonant modes of movement is not operated vehicles [2,7,11] have shown that the development of resonant mode (the maximum deviation of the longitudinal axis of the landing vehicle of the velocity vector) is held for a short time of a few seconds.…”

Unsteady Aerodynamic Flow Control of Moving Platforms

“…The basic motions of spinning projectiles, including natural nutation and precession linear and nonlinear instabilities, induced by Magnus, damping, and normal forces and moments are discussed in detail in the classical work of Nicolaides (1970). The instabilities of axisymmetric bodies in the presence and absence of spin were discussed in detail by Murphy (1980). While the spin- stabilized ones are gyroscopically stable to axisymmetric moment instability, they are susceptible to roll resonance (Price, 1967), and spin-yaw lock in (Murphy, 1987), which add complicated non-linear effects to the body dynamics that are in general hard to correct for.…”

Passage Through Resonance of Rolling Finned Projectiles With Center-of-Mass Offset

“…A detailed review of the theory of resonant lock-in of rolling "nned projectiles with illustrative calculations has been provided by Ananthkrishnan and Raisinghani [7]. Dynamic instabilities of missiles and re-entry vehicles, including roll lock-in, have been reviewed in the papers by Murphy [8] and Platus [9]. A recent paper by Platus [10] discusses the problem in the context of coning instabilities in missiles and spacecraft.…”
