Definitions

  • Another object is to provide a simple but effective means for converting the projectile air frame into the air foil structure at the most opportune moment of flight and with good reliability of performance.
  • a projectile that consists primarily of a segmented, tubular rocket simulating body in which the segments are hinged and formed to provide a rocket-vehicle like configuration in the closed condition and, upon opening, provide radially disposed air foil members which operate in the manner of an autogyro or helicopter to provide gyro rotation of the vehicle for slow descent after the projectile has reached its apogee.
  • the segmented members making up the major portion of the rocket body are elastically biased in such a manner as to cause the segments to be deployed as a blade wheel under static conditions, but may be easily folded and held in a folded condition under the normal arerodynamic forces attendant with the flight of the vehicle after launching.
  • Launching of the vehicle may be accomplished through use of the well-known sling shot hand launcher, C6 cartridges or may be accomplished by incorporation in a multi-stage toy missile such as that disclosed in my copending application Serial No. 214,049, filed August 1, 1962.
  • the projectile is launched in an upward direction and, as long as the aerodynamic force imposed by the air flow is present on the folded segments, the projectile retains the configuration of a rocket-type missile.
  • the dynamic forces imposed by air flow decrease to a point where the elastic loading causes the segments to pivotally deploy to a radially disposed position.

  • Compression spring 20 is coaxially mounted within nose member 2 and seats,
  • the baseor tip ofthe vane to provide low drag at the point of highest velocity when the vane is rotating.
  • the projectile assumes a blade-wheel configuration (FIG. 7) and begins descent 7 under the influence of gravity. Air how, normal to the vanes, induces rotation thereof, as, described above, the rotation providing chordwise air flow along the vanes and inducing lift therein through principles well known in the art.
  • the induced lift retardsTdc-scent of the projection and auto-rotative, helicopter'type of toy is
  • the threaded spring compression adjusting means pro- 7 vides adjustment of the bias urging the vanes outwardly and'provides a means to vary the height of deployment of the'vanes.

  • vanes 4 are configured ih'a closed 'condition, as shown in FIG. 1. This disposes piston 6 in an upward condition through the camming action of levers 32 and compressesspring 2G. The missile is then launched by any suitable means such, for example, as sling shot 40 hooked under nose fin 12. Aerodynamic force retains vanes 4 in an essentially closed cylindrical configuration until'the velocity of the missile drop 01f. When the aerodynamic force drops below the bias forceof spring 29,
  • lever minimum at the base end This produces a maximum asymmetry at the hinge portion of the vane to induce rotation of the. projectile, and a minimum asymmetry at This hinge like by suitable adjustment of the bias force.

  • A' pair of oppositely disposed teeth 56 are provided in aperture 46 to engage lands 54 when pin 48 is suitably rotated with respect thereto as shown in FIG. 6.
  • FIG. 6 a plan view of pin 48 disposed in aperture46 is shown with teeth 56 engaging lands 54 to hold elastic band 42 at aselected elongation to provide desired tension therein.
  • Tension in band 42 may be changed by rotating pin 48 ninety degrees from the position shown to place lands 54 in'alignment with enlarged v portion58, of'aperture 46, axially displacing pin 48 to a force for vanes 4 may be adjusted for desired position, and rotating the pin ninety degrees to re-engage teeth 56with lands 54. i In this way, the biasing purposes described for the embodiment of.

  • nose portion 2a is of a similar outer configuration to nose member 2 of FIG. 1. However, since the adjustment feature of FIG. 1 is not required in the embodiment of FIG. 5, nose portion 2a is an integral unit. .
