  • Patent number: 6055909
    Abstract: This invention proposes to make use of an already developed set of hardware which dispenses and controls the performance of towed decoys capable of defeating radar guided weapons. Using this same hardware, a new and unique payload, payload control and dispensing mechanism is inserted into a decoy towbody. The payload consists of foils and/or foil packs of a pyrophoric material. This material creates an infrared (IR) signature behind the decoy that is more attractive than the infrared plume emitted by the aircraft engine. The fact that the IR decoy is towed insures that it will be kinematically correct by flying the same profile as the aircraft so as to remain within the field of view of the missile's seeker. Because the pyrophoric material can be metered (dispensed at varying and controllable rates) its radiant intensity can be matched with that of the engine of the towing aircraft.

    Abstract: It is known to use a rigid cone to provide stability to a body being towed by an aircraft. However, such cones are useful over a limited range of speeds. The invention provides a drag-producing aerodynamic device in which the cross-sectional area of the structure producing drag is variable. The cross-sectional area of the structure producing drag decreases as the towing speed, and hence the dynamic air pressure acting on the structure producing drag, increases and vice versa.

    Abstract: The invention extends the operational envelope of towed bodies at high altitudes and at high dynamic pressures. It features fins with large span/chord ratios, compactly stowed along the body surface, pivotally swept back with their chord broadside to the airstream. These fins generate high drag forces and large stabilizing and damping moments, even at supersonic speeds. Sweepback angles, controlled by elastic restraints, increase as fin loads increase. This minimizes variations in cable tension, even in maneuvers. Fin drag forces can also extend telescopic body elements. Fin settings can also generate vertical or lateral forces to bias decoy position.

Prior to deployment or after retrieval of the towed body the arms are in a horizontal position while during deployment or a retrieval one arm is in a vertical position. When in the vertical position, a complementary mating arrangement on the towed body ensures for a positive engagement with the arm so as to prevent excessive movement of the towed body when captured. In order to reduce tension on the cable for irregular movements of the towing body, one arm assembly is affixed in a bearing arrangement so as to allow rotation about its longitudinal axes.

  • Patent number: 4852455
    Abstract: A decoy system is disclosed characterized by use of a rotating towline spool having an axial bore therethrough adapted to receive a pyrotechnic charge adjacent one end thereof and communicate gas pressure upon detonation of the charge to the decoy to deploy the decoy from an aircraft. Pyrotechnic charges for both decoy ejection and towline cutting may be externally loaded into the system without the need to disassemble the decoy system and the use of the axial bore through the spool results in desired space economies. The interior of the decoy cannister is provided with plural guide rails and contoured guide rollers which facilitate ejection of the decoy from the cannister in directions even or perpendicular to the airstream of the aircraft. Towline spool and decoy terminations and a method of fabricating the same are disclosed which yield sufficient strength to withstand peak tensile forces exerted during initial acceleration and subsequent maximum pay out of the decoy.

  • Patent number: 4805159
    Abstract: The minimum distance between a passing projectile and a training (dummy) target is ascertained by means of four shock wave responsive transducers in the target, two of which are aligned with the target's propagation and the transit time differential of receiving the shock wave from the projectile as well as measured distances to the projectile's trajectory are used to establish a set of possible projectile trajectories, one of them being the real one; all of them being arranged in rotational symmetry to the line established by the two transducers. This information suffices already to determine the minimum distance of fly by.

  • Patent number: 4770368
    Abstract: A turbine/air vent reeling machine for use in aerial towed target applications and the like disclosed characterized by use of a novel turbine head/air vent design which extracts ram air energy from the wind stream impinging upon a moving aircraft for the purpose of driving and braking the reeling machine for pay-in and pay-out of a towed target. Control of the turbine rotational speed is achieved through plural variable opening vents located aft of the turbine head which are driven through an open and closed orientation by a servo-motor to throttle the air mass flow through the turbine head. Turbine speed is sensed by a tachometer which is coupled to a shaft driven by the turbine. The tachometer output voltage is introduced into a closed loop control circuit including processing electronics which compares the tachometer voltage to a pre-selected set point voltage corresponding to the desired rotational speed of the turbine.
