  • 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...

  • 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...

  • 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...

  • Optimal soaring by a small autonomous glider

    Creator:
    Kyle, Jason A.
    Abstract:
    Extending the flight time of an autonomous unmanned air vehicle by soaring is considered. A suboptimal controller is developed and successful static soaring is demonstrated with a 6 degree of freedom glider model. Altitude gain rates of between ¼ and ½ m/s are achieved with this simple implementation. A hybrid...
