  • Patent number: 9490681
    Abstract: An electric generator includes a housing with a stator positioned thereabout. A rotor (i.e., magnetic member) is positioned within the housing and is adapted to move within the housing in response to a pulsed air input, such as from a pulsed-air exhaust device. The pulsed air input creates a pressure chamber between the pulsed air input and the magnetic member, which forces the magnetic member to axially advance in a first direction through the housing to magnetically interact with the stator to generate electric current therein. A biasing member may be positioned within the housing and in operative communication with the magnetic member. The magnetic member may compress the biasing member in the first direction, but the biasing member may exert a spring-back force against the magnetic member to force the magnetic member in a second direction through the stator to magnetically interact therewith to generate additional electric current therein.

  • Patent number: 8919253
    Abstract: A perforating system that transfers a detonation wave between adjacent perforating guns by converting shockwave energy to electrical energy. An explosive is provided on an end of a detonating cord that is coupled to shaped charges, so that a detonation wave traveling in the detonation cord will initiate detonation in the shaped charges and then in the high explosive. The explosive is disposed adjacent a pair of members that are energized so that a magnetic field is formed between the members. When the explosive detonates, the resulting shock wave pushes one of the members into the space between the members to compress the magnetic field. Compressing the magnetic field produces an electrical potential usable to initiate a detonation wave in another detonating cord for perpetuating the detonation wave along the perforating system.

The electronic fuze (200) includes a voltage generator circuit (210), micro-controller (220), a piezo-electric sensor (262), a firing circuit (280) and a safety lockout circuit (290).

The safety lockout circuit (290) ensures the firing circuit (280) is operative only after a predetermined delay time when an n-channel FET (292) is turned OFF. The micro-controller (220) also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode.

  • Publication number: 20120204747
    Abstract: A method for providing electrical energy to a self-destruct fuze for submunitions contained in a projectile is provided. The method including: using a firing acceleration of the projectile to deform at least one elastic element to store mechanical energy in the elastic element; converting the stored mechanical energy to electrical energy; and providing the electrical energy at least indirectly to the self destruct fuze for detonation of the self destruct fuze. Alternatively, the firing acceleration can lock the elastic element in the deformed position and an expulsion acceleration of the submunitions from the projectile can be used to unlock the elastic element and convert the stored mechanical energy to electrical energy.
