  • Two projectiles connected by a flexible tether dropped in the atmosphere

    Creator:
    Frost, Geoffrey W.
    Abstract:
    This study investigates the atmospheric flight dynamics of a munition system and the effect of a tether reel resistance mechanism for limiting the impact that the unreeling process has on the munition system. The munition system consisting of two projectiles connected by a tether line is released from an aircraft...

  • Performance of a smart direct fire penetrator using a ram air controlled mechanism

    Creator:
    Chandgadkar, Siddharth Suhaschandra
    Abstract:
    The effectiveness of a direct fire penetrator projectile equipped with an actively controlled ram air mechanism is investigated through dynamic simulation. The ram air control mechanism consists of a rotary sleeve valve which directs air flow from an inlet at the center of the nose to side ports. The projectile...

  • Solutions of plate equation for the prediction of ink droplets in inkjet cartridges

    Creator:
    Sangplung, Saangrut
    Abstract:
    Droplet formation in inkjet cartridges has been studied for several decades to improve print qualities. Currents and rigid nozzle plates are used inside the cartridge to fix the size of droplets exiting the chamber. This research is focused on studying the effect of nozzle flexibility on droplet formation. A flexible...

  • Modified linear theory and Kalman filtering for in flight projectile impact point prediction

    Creator:
    Hainz, Leonard C.
    Abstract:
    A method for real time in-flight prediction of the ground impact point of an indirect fire projectile is investigated. The method investigated is comprised of a combination of an impact point predictor and an extended Kalman filter state estimator based on modified linear theory. The modified linear theory model is...

  • Model predictive control of a direct fire projectile equipped with canards

    Creator:
    Ollerenshaw, Douglas R.
    Abstract:
    Launch uncertainties in uncontrolled direct fire projectiles can lead to significant impact point dispersion, even at relatively short range. A model predictive control scheme for direct fire projectiles is investigated to reduce impact point dispersion. The control law depends on projectile linear theory to create an approximate linear model of...

  • Initial state estimation for a gun launched projectile in a spatially varying magnetic field

    Creator:
    Chawla, Feni
    Abstract:
    Smart weapons promise to provide leap ahead capability with regard to accuracy and engagement range for medium and large caliber projectiles. One of the most critical components of a smart weapon system is its sensor suite that provides position, orientation, and velocity information as the projectile flies down range so...
