Abstract

A telescoped ammunition cartridge assembly including a case having a front end and a base end positioned along a longitudinal axis. A projectile is positioned along the longitudinal axis towards the front end of the case. An endcap is coupled to the front end of the case and is adapted to retain the projectile entirely within the case. A primer is positioned along the longitudinal axis towards the base end of the case. A primer support is coupled to the base end of the case and is adapted to support the primer within the case. The cartrige assembly includes at least one obturating lip seal to seal at least one of the endcap or the primer support to the case.

Abstract

Apparatus for the recovery of an aircraft includes a capture device and first and second pole pairs. Each first and second pole pair includes top and bottom poles. First pole pair is configured to move from a first position, in which the pole pair holds the capture device in an open position to capture the aircraft, to a second position, in which the pole pair holds the capture device in a closed position to contain the captured aircraft after impact of the aircraft on the capture device. The second pole pair is also configured to move from the first position to the second position. Energy elements coupled on one end to a respective top or bottom portion of the capture device and on another end to a respective top or bottom pole, are disposed to absorb the force of the impact of the aircraft.

Abstract

A method for generating a synthesized waveform from a desired arbitrary waveform via a convolution processor includes: providing a data stream input signal to the convolution processor including an extended duration impulse signal; computing one or more filter coefficients of the convolution processor; and generating the synthesized waveform substantially similar to the desired arbitrary waveform using the filter coefficients. The convolution processor may be a finite impulse response (FlR) filter. The convolution processor may perform a convolution upon the extended duration impulse signal, where: the extended duration impulse signal is successively delayed via one or more taps and the output of each tap is multiplied by a filter coefficient corresponding to a delay; and the summation of the products of tap outputs and filter coefficients is the desired arbitrary waveform.

Abstract

A portable unmanned air vehicle and launcher system is provided that includes a foldable unmanned air vehicle having a pressure tube; a launch gas reservoir for holding launch gas; a launch tube operatively connected to the launch gas reservoir and having a free end that is positioned in the pressure tube of the air vehicle; a free piston positioned within the launch tube; and a free piston stop to prevent the free piston from leaving the launch tube. A first portion of the launch gas in the launch gas reservoir is released into the launch tube and forces the free piston from an initial position to an end position at which the free piston is stopped by the free piston stop.
