Abstract: Flight behavior of a mortar launched, parachute deployed imaging system is examined with particular attention to characterizing the quantity and quality of recorded image data. Coverage area of ...

Abstract: A key technical challenge for smart weapon developers is the design of appropriate control mechanisms that provide sufficient control authority to enable correction of typical trajectory errors ...

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 ...

Abstract: Internal masses that undergo controlled translation within a projectile have been shown to be effective control mechanisms for smart weapons. However, internal mass oscillation must occur at the ...

Abstract: A simple testing device is presented that simultaneously calibrates all dominant error sources for accelerometers and gyroscopes found in typical microelectromechanical inertial measurement units ...

Abstract: There are numerous ways to estimate the trajectory and subsequent impact point of a projectile. Some complex methods are highly accurate and require a lot of input data while others are fairly trivial and less accurate but ...

Abstract: The linear theory for spinning projectiles is extended to account for the application of a simple lateral square impulse activated during free flight. Analytical results are shown to produce ...

Abstract: The effectiveness of a direct fire penetrator projectile equipped with an actively controlled ram air actuation mechanism is investigated through dynamic simulation. The ram air control mechanism ...
