  • Patent number: 5323708
    Abstract: A clip-lock cap for protecting saboted projectiles or penetrators. This cap is formed of several independent segments held together by mechanical clips, the latter being designed to be released from the segments and thus allow dispersal of the segments only when the combined penetrator and cap is exposed to high axial acceleration. It will be understood that because the cap separation from the projectile is achieved through mechanical means, the cap segments can be designed to be as rugged as required to meet rough handling loads and environmental requirements without affecting the reliability or repeatability of the discard process and irrespective of segment material, environmental conditions or projectile spin rate.

  • Patent number: 5280751
    Abstract: A munition incorporating a miniature transmitter (25) and a piezoelectric power supply (45) which converts a portion of the kinetic energy of the projectile (20), upon impact, into radio frequency energy and radiates that energy into space. The transmitter (25) can be made in suitable sizes to fit various calibers of ammunition. Different caliber ammunition can be made to radiate different frequencies. The transmitted RF energy allows the point of impact of the projectiles to be located with a high degree of precision. This type of munition may be used in the scoring of air to ground gunnery in training environments by receiving the RF energy at several known locations and determining the point of impact using time of arrival or angle of arrival techniques. Frequency discrimination allows simultaneous scoring of multiple weapons from the same aircraft or from multiple aircraft. The munition may be employed in tactical applications by allowing the fall of fire to be located and adjusted.

  • Patent number: 5103734
    Abstract: The invention concerns a guided munition, fired from a launching system with a cannon effect. This munition comprising sub-assemblies is supported, during acceleration in the cannon, by a peripheral casing which rests on the first sub-assembly of the munition placed at the front of the munition and is fixed to an ejectable sub-assembly placed at the rear of the munition. The weight of this casing is necessary to withstand the forces due to acceleration and it enables the range of the munition to be increased during the ballistic phase. During the transition from the ballistic phase to the guided phase, the ejectable sub-assembly is ejected, taking with it the casing which thus frees the airfoil surfaces to open out. The casing thus positioned also provides sealing and protection of the sensitive parts and rigidity of the whole of the munition.

  • Patent number: 5036770
    Abstract: A protective door assembly is disclosed which will cover missile altitude control system engines during storage and launch while still being easily jettisoned when the ACS engine is fired. The titanium door attaches to the missile skin by a hook on it's lower edge and by a tapered boss which attaches to the skin and fits into a tapered hole near the door upper edge. Behind the door, the ACS engine nozzle is surrounded by a seal housing which prevents engine gases from escaping into the body of the missile and causing a pressure buildup when the engine is fired. At pressures between 35 and 60 psi, the door retainer screw fails in tension and the door is blown off.

  • Patent number: 5027709
    Abstract: A system for powering and communicating with a mine or mine simulator, involving magnetic induction coupling between a powered search unit with a resonating primary inductance coil and a secondary inductance loop in the mine device. The current in the secondary loop is rectified in the mine device to provide dc power. The magnetic induction frequency can be in the range from 40 kHz to 1 MHz. The search unit can resonate sequentially or simultaneously at different frequencies, and rectification of the different frequencies in the mine device can provide information to the mine device. Feedback to the search unit can be by the mine device modulating the impedance of its secondary loop, for instance at an audio frequency 1/10th of the frequency of the induction coupling, and by detecting in the search unit the corresponding change in the reflected impedance. A mine device can be armed or disarmed, and report on its status when queried by the search unit coming sufficiently close to the mine device.

  • Patent number: 4991513
    Abstract: The invention is a carrier projectile 10 having a safety venting system wh prevents expulsion of the projectile cargo during accidental or inadvertent initiation of the expulsion charge 21. The venting system comprises a collar which closes vent holes when the projectile is fired. The normal activation sequence of the carrier projectile is firing to a predetermined range or time, activation of the expulsion charge thereby bursting open the carrier shell, and dispensing of the cargo. The venting system incorporated into the present invention precludes bursting of the carrier shell, even if the activation of the expulsion charge occurs, unless the vents have been closed by the actual firing of the projectile. The venting system provides a safety feature in the event that the projectile is subjected to fire or other thermal stress and in the event of a hot gun misfire the collar is operated by either angular acceleration or longitudinal acceleration.

  • Patent number: 4969398
    Abstract: A lane marker preferably for delivery by a CATFAE weapon, has a mechanical imed device which is positioned and rides in the rear section of the CATFAE weapon as it is launched to a specified position on the ground. At first contact of the CATFAE with the ground, the lane marker is ejected vertically a short distance away from the ground and then falls onto the ground. On the ground the lane marker attitude is controlled for effective employment. Spring-biased probes deploy the makers which typically comprise two flags and two chemiluminescent lights to mark the impact point of the CATFAE. The two chemiluminescent lights are activated mechanically by cloud detonation overpressure prior to deployment of the spring-biased probes.

  • Patent number: H1150
    Abstract: An improved parachute recovery system for a gun fired projectile is discld. The projectile has a nose, a payload and a base section. The base section has a hollow cylindrical parachute cannister which is separated from the base section by rearward motion of an internal piston which is actuated by expulsion gas pressure initiated by a time fuze. The parachute cannister is thereby exposed and jettisoned to cause inflation of a parachute attached to the base section so that the parachute floats down in a nose-deployed projectile position for a soft landing and recovery. Also disclosed are alternative embodiments of a projectile base-deployed parachute recovery system.
