Abstract
A decoy missile having a high moment of inertia with a corresponding reduction of the natural oscillation frequency for simulating reentry of a ballistic nose cone into the earth's atmosphere. High density ballast material disposed in the forward section is in proportional relationship to similar ballast material in the base section such that the distance between the center of pressure and the center of gravity is equal to one-half the base diameter.
Claims4
A decoy missile for simulating the characteristics of a ballistic missile nose cone during reentry into the earth's atmosphere, said decoy missile comprising a rounded nose portion having a hollow elongated body portion extending rearwardly therefrom, said decoy missile being symmetrical about its longitudinal axis, and means for reducing the natural oscillation frequency of said decoy, said means including a front ballast disposed in the forward section of said body portion immediately adjacent to said nose portion and a rear ballast disposed in the rearwardmost base section of said body portion, thereby providing a high moment of inertia and reducing the natural oscillation frequency of said decoy to match that of the ballistic missile nose cone.
