NASA SBIR Phase II: Computational Tools for Aerodynamic Modeling, Analysis, and Control

Nov. 2004: NASA Dryden has awarded a Phase II SBIR contract to develop computational tools for aerodynamic modeling, analysis and control directed towards application for high performance unmanned aerial vehicles. For small-unmanned aerial vehicles a well-designed network of micro actuators can enable aggressive performance not possible using traditional control surfaces such as ailerons, elevators, rudder and flaps. Even for larger aircraft the emerging paradigm of control involves an array of actuators and distributed sensing and actuation. In addition to enhanced performance these control architectures can provide greater redundancy to confront actuator failures. The proposed toolbox in conjunction with commonly used general purpose software will provide designers the ability to seamlessly test control design for aerodynamic applications by integrating and automating several key steps in design cycle. These tools will find commercial applications not only in the emerging unmanned aerial vehicle industry but other land, sea and air vehicles as well. Dr. Gaurav Bajpai is the principal inestigator and Mr.Eric Salter the principal specialist on the project, they will be aided by Dr.Ben Shapiro at University of Maryland.
