Abstract
THE PROPOSED WORK CONCERNS A NOVEL APPROACH TO THE STUDY OF AERODYNAMICS DURING TRANSIENT MANEUVERS. PREVIOUS WORK HAS SHOWN THAT AUGMENTED AERODYNAMIC CHARACTERISTICS, SUCH AS VERY HIGH LIFT COEFFICIENT, MAY BE OBTAINED DUE TO THE TRANSIENT NATURE OF SOME MANEUVERS. THE FLUID MECHANICS THAT AFFECT THESE DESIRABLE CHARACTERISTICS CAN BE COMPLEX AND DIFFICULT TO STUDY, DUE TO THEIR TRANSIENT NATURE, AND DUE TO THE COMBINATIONS OF PITCH, ROLL AND DECELERATION THAT MAY OCCUR. THIS PROPOSAL CONCERNS THE DEVELOPMENT OF A COMPUTATIONAL ANALYSIS TECHNIQUE FOR EXAMINING IMPORTANT SUB-ELEMENTS OF THE FLOWFIELDS THAT ARISE DURING SUCH MANEUVERS. THE TECHNIQUE WILL DETERMINE THE CRITICAL FLUID MECHANISMS WHICH CONTROL THE FLOW IN THE SUBELEMENT. THE ULTIMATE OBJECTIVE IS TO EXAMINE METHODS OF EXISTING CONTROL OVER THE SUB-ELEMENT FLOWS, IN AN EFFORT TO ACHIEVE MORE DESIRABLE AERODYNAMIC CHARACTERISTICS.
