Aerodynamic Optimization of Microspoiler Actuators for Guided Projectiles

Microspoiler Actuation for Guided Projectiles

The goal of this project was to further mature microspoiler technology to the extent that it could be incorporated into current and future smart weapons designs. Several program objectives, including mechanical design and fabrication, trade study analysis, and limited flight experiments were defined as a collaborative effort between the Georgia Institute of Technology (Georgia Tech) and the Arm...

Micro Balloon Actuators for Aerodynamic Control

A robust, large-force, large-deflection micro balloon actuator for aerodynamic (maneuvering) control of transonic aircraft has been developed. Using a novel process, high yield linear arrays of silicone balloons on a robust silicon substrate have been fabricated that can deflect vertically in excess of one 111111. Balloon actuators have been tested under cyclic conditions to assess reliability....

Optical Flow-Based State Estimation for Guided Projectiles

Efficient Aerodynamic Shape Optimization

Since the present author first became involved in computational fluid dynamics, around 1970, the landscape has changed dramatically. At that time, panel methods had just come into use, and the world’s fastest super computer, the Control data 6600, had only 131000 words of memory (about 1 megabyte). Prior to the break-through of Murman and Cole [1970], no viable algorithms for computing transoni...
