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...

Human gait analysis by gait pattern measurement and forward dynamic model combined with non linear feedback control

Creator:: Ko, Seung-uk
Abstract:: Normal gait of human is believed to be an adapted motor control result of optimal behavior of individual. Normal gait would be altered by aging or injury without being perceived. Subtle changes in gait which is not easy to detect, can cause many serious problems including joint pains and even...

An experimental study of the fluid mechanics of filling a small part of modular mold

Creator:: Miller, Mark Wade, 1967-
Abstract:: Investment casting has been an important form of metal casting for many years, but little is understood about the fluid flows that occur during mold filling. A key to quality castings is the understanding and control of the fluid flows that are present when the mold is filled with molten...

Dynamic modeling, control and linear theory of a projectile equipped with a rotating internal part

Creator:: Frost, Geoffrey W.
Abstract:: Dynamic modeling of the atmospheric flight mechanics of a projectile equipped with an uncontrolled internal rotating disk is investigated and a modified projectile linear theory is established. It is shown through modeling of this type of projectile that several coefficients of the epicyclic dynamics are altered, leading to changes in...

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...

Dynamic modeling, control aspects and model predictive control of a parafoil and payload system

Creator:: Slegers, Nathan J.
Abstract:: Control issues are investigated for a parafoil and payload system with left and right parafoil brakes used as the control mechanism. It is shown through dynamic modeling and simulation that parafoil and payload systems can exhibit two basic modes of lateral control, namely, roll and skid steering. Using a small...

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...

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...

Lateral pulse jet control of a direct fire atmospheric rocket using an inertial measurement unit sensor system

Creator:: Jitpraphai, Thanat
Abstract:: Impact point dispersion of a direct fire rocket can be drastically reduced with a ring of appropriately sized lateral pulse jets coupled to a trajectory tracking flight control system. The system is shown to work well against uncertainty in the form of initial off-axis angular velocity perturbations as well as...

Natural convection and conduction in a vertical annulus with a concentric baffle : a numerical study

Creator:: Fishbaugher, Mark J.
Abstract:: Analytical and numerical study of steady-state laminar natural convection and conduction has been performed for an enclosure between concentric vertical cylinders. The inner and outer cylinders were isothermal, and the connecting top and bottom walls were adiabatic. A concentric baffle was included in the annulus, and the flow field and...
