Abstract:

THE PROPOSED EFFORT WOULD DEVELOP A PREDICTIVE TECHNIQUE FORTHE PROJECTILE BASE FLOW REGION INCLUDING THE EFFECTS OF BASE INJECTION AND SPIN. THE TECHNIQUE WOULD BE BASED UPON A SOLUTION OF THE NAVIER-STOKES EQUATIONS WITHOUT THE ASSUMPTION OF AXIAL SYMMETRY, AND WOULD BE APPLICABLE FROM THE LOWSUBSONIC MACH NUMBER RANGE THROUGH THE MID SUPERSONIC RANGE FOR FLOW ABOUT BOTH AXISYMMETRIC AND NON-AXISYMMETRIC BODIESAT PRESENT MOST TECHNIQUES FOR PREDICTING THE PROJECTILE B BLEED FLOW ARE BASE UPON RELATIVELY SIMPLE EMPIRICAL ANAY LSES OR ARE DRESTRICTED TO ASSUMED AXISYMMETRIC FLOW. THE BASED UPON A HIGH RESOLUTION NAVIER-STOKES STUDY AND , THEREFORE, WOULD SIMULATE THE PHYSICS FROM THE GOVERNING EQUATIONS. UNDER THE PHASE I EFFORT, A GENERAL NAVIER-STOKESCODE WOULD BE APPLIED TO THE PROBLEM AND DEMONSTRATION CAL CULATIONS WOULD BE MADE. FUTURE EFFORTS WOULD FOCUS UPON A QUANTITATIVE ASSESSMENT OF THE PROCEDURE OVER A WIDE RANGE OF FLOW CONDITIONS, APPLICATION FOR THREE-DINENSIONAL FLOW I.E., BODY AT ANGLE OF ATTACK, CREATION OF BASE DRAG PER FORMANCE CURVES AND DEVELOPMENT OF A USER FRIENDLY CODE.
