Abstract A missle such as a ball incorporating a weighted mass having selected optimum for a given mass, velocity, spin and size while simultaneously making I as large as possible. The optimum selected weighted mass creates the desired in-flight path of the missile which experiences less perturbation so that missile precession and nutation is suppressed. In one form, the missile includes an elliptical spheroid such as a football having the selected weighted mass provided in an enclosure or covering with a hollow shell having a cavity containing an air volume. A cushion material such as foam is carried on opposite ends of the ball separating the shell from the covering. A band is disposed about the enclosure and shell midsection coaxially disposed with respect to the central longitudinal axis of the elliptical spheroid. Arcuate projections or arms are carried on the band in pairs cantilevered outwardly from opposite sides of the band adjacent to the shell Each pair is substantially separated from the other pair by 90 degrees and includes weighted ends.
A game ball adapted to be thrown in a spiral comprising: a thin walled shell of oblong configuration having opposite ends separated by a midsection and defining a cavity in which pressurized air may be contained; a weighted mass disposed about said midsection of said shell contributing to the stability of the ball in flight as it spins about a central longitudinal axis; a cover enclosing said shell and said weighted mass and in spaced-apart relationship from said shell to define voids therebetween; filler material carried about said shell occupying said voids between said cover and said shell; said weighted mass including a ring carried about said shell at its longitudinal midsection and a pair of outwardly projecting reinforcement arms located on opposite sides of said ring in a cantilevered manner; said arms including a weight element at the free end of each cantilevered arm; and the arms of each of said pairs of arms, respectively, being disposed 180 degrees apart, in first and second plane which are 90 degrees apart.
