Definitions

  • ABSTRACT A rotatable airfoil munition comprising a hollow closed circular ring surrounding a central open area with the detonation system and military filling material positioned within the hollow ring.
  • the munition projectile consists of an aerodynamic lifting body of a thick ring wing geometry which uses spin imparted to it from a launching means for its gyroscopic stability, thus permitting a relatively flat trajectory as compared with the prior art munitions which require a loft trajectory for substantially the same range.
  • This invention relates to significant improvement in the range ofmunition projectiles while providing a relatively flat trajectory as compared to the conventional ballistic trajectory.
  • the object of this invention is to provide an extended range capability without the need for the additional weight and cost of the rocket motor arrangement.
  • a further object of this invention is to provide a munition projectile whose terminal ballistics capability, on a lethality per pound munition basis, represents a sig nificant increase over conventional projectiles.
  • This invention is directed to a body of revolution forming a closed circular airfoil warhead, Ring Airfoil Munition, with a hollow configuration surrounding a central opening rotating about an axis in the general direction of its trajectory toward the impact area.
  • the hollow section houses the payload and explosive train.
  • This invention relates to a new munition configuration based on a ring airfoil or ring wing whereby a body of revolution generated by the airfoil cross section rotated 360 about an axis beneath and parallel to the longitudinal direction of the airfoil cross section.
  • the principal object of this invention is to provide a munition which will be more effective to overcome enemy resistance.
  • Another objective is to provide a munition which will be more effective in utilizing direct-in-line fire trajectory.
  • Another objective is to provide a means for greater destruction of the target area without materially increasing the payload.
  • inventive warhead may be fired from any conventional launcher which utilized a sabot cartridge.
  • Still a further objective is to provide a ring airfoil munition with a low angle of elevation for its primary trajectory.
  • the conventional projectiles have a basic deficiency in that mid to maximum ranges cannot be achieved without resorting to the normal loft trajectories resulting from relatively high elevation angles, for example 30 to 45.
  • the aeroballistic configuration of the present warhead overcomes the former limitations of the loft trajectory and permits a 5 to 7 angle of elevation of the launcher for substantially the same range as the 35 angle of elevation required for the 40mm M-39 grenade system. Additionally, the inventive warhead may also be launched for a loft trajectory if desired.
  • the inventive projectile warhead provides major improvements in trajectory capability with increased range by a factor of 2 or more for the same launch velocity and weight of the projectile as the M-406 grenade.
  • the inventive warhead has demonstrated a significant increase in lethality for the same amount of HE (high explosive) as used in the conventional 40mm grenade (M-406).
  • the unique aerodynamic characteristics of the ring airfoil configuration results in permitting the soldier to fire on a substantially direct line to the target area.
  • the configuration of the present invention possesses aerodynamic properties which are not available in conventional ballistic projectiles.
  • the munition is rotating about its axis of symmetry which is central to the body of revolution formed by rotating the airfoil cross section about the same axis.
  • the spin rate should exceed about 2,000 rpm, and preferably should far exceed 2,000 rpm.
  • the rotational motion produces gyroscopic stability so that although the attitude ofthe projectile tends to remain relatively constant, the angle of the ring airfoil projectile along the trajectory produces a lift force which partly offsets the influence of gravity.
  • the airfoil cross-sectional contour and ring arrangement result in more uniform fragment distribution over a larger area than can be achieved with the M406 grenade.
  • the ring airfoil configuration can therefore be utilized in a tactical role wherein it may be either exploded in air in the proximity of the target or exploded by direct impact with the target.
  • the fragment spray pattern of the M-406 grenade is generally limited to the rearward direction only and totals approximately
  • the lethality as developed from the arena data results in a substantial increase for the inventive warhead as compared to the M-406. This is due, in part, to both the increase in the number of available fragments resulting from the ring airfoil geometry and the absence of any shielding in the structure, which provides the inventive munition with a significant increase in fragment distribution as compared to the M 406.
  • FIGS. 1 and 3 illustrate the spray patterns and distribution of fragments resulting from the arena tests.
  • FIG. I is a longitudinal sectional view of FIG. 2.

  • the straight arrows indicate the path of flight.
  • the curved arrow indicates the direction of rotation.
  • the warhead is a self-contained unit and the configuration, rather than being provided with any specific payload. is adaptable to the various military filling material useful in warfare. Further, as is conventional with such military hardware, the warhead, in accordance with this invention, FIGS. 3 and 7, is provided internally with a fuze 7, position in the aft fuze ring 5. initiating the booster lead 11, then the booster 13, which sets off the explosive fill 15, and this in turn produces the force that breaks up the exterior surface of l and expells the preformed fragments.
  • These aforesaid internally functional elements are conventional and the purpose and manner of operation thereof are well known to those skilled in the art.
  • Other fuse locations are contemplated including for example, an inner ring fuze such as is illustrated in FIG. 8 and sector fuzing as is illustrated in FIG. 9.
  • Contemplated in this invention are the other various state-of-the-art fuzes functioning with time, impact, proximity, or command, providing safe separation from the launcher prior to arming in flight.
  • the present invention is superior to prior art devices for destroying or incapacitating military objectives by means of high explosive-fragmentation, incendiary ma terials, or incapacitating matter.
  • the projectile may be filled with chemical materials which will yield a vapor when released from the projectile structure.
  • chemical materials include phosgene, mustard, a-chloroacetophenone.
  • Other projectile filling components may yield a smoke, for example, white phosphorus, sulfur trioxide with chlorosulfonic acid, or incendiary material such as thermit which is black non-oxide mixed with aluminum or white phosphorus.
  • the airfoil cross-sectional utilized in the ring airfoil grenade is rather thick; that is, in order of to of the chordal dimension. preferably about 25-30%, at its point of maximum thickness.
  • the emphasis on this amount of thickness is to allow sufficient explosive to be loaded within the airfoil warhead and obtain a relatively high charge to mass ratio. This is the ratio by means of which the basic explosive and fragment velocity characteristics may be predicted as well as provide a basis for performance comparison with other warheads.
  • the ring airfoil's forward (leading) and rearward (trailing) edges are shaped so that the leading edge radius is noticeably greater in radius than the trail' ing edge which forms part of the aft fuze ring in the fuzing mode illustrated by FIG. 7.

  • the outer unit is internally preformed for more precise fragmentation.
  • the three portions are joined together by conventional means such as epoxy bonding agents or other metal to metal binding agents which will cause these portions to be structurally integral under the conditions of use.
  • the warhead can be unitized by conventional metal joining processes.
  • FIGS. 8 and 9 illustrate ring and sector fuzing, respectively, which fuzing systems might be incorporated into the warhead, the structural components of the warhead being always appropriate to the fuzing selected and, of course, consistent with aerodynamic stability requirements.
