Abstract:

OVER THE PAST SEVERAL YEARS SIGNIFICANT INTEREST HAS BEEN GENERATED IN THREE-DIMENSIONAL FLOWFIELD ANALYSES OF LIFTING REENTRY VEHICLES. THE PARABOLIZED NAVIER-STOKES (PNS) SCHEMES ARE ELLIPTIC IN THE CROSSFLOW DIRECTION AND CAN TREAT REGIONS OF CROSSFLOW SEPARATION. THE PRESENT NON-ITERATIVE AFWAL PNS SCHEME SUFFERS FROM QUITE A FEW LIMITATIONS AND RESTRICTIONS; HOWEVER, THE NEW FULLY-ITERATIVE PNS SCHEME OF BHUTTA AND LEWIS SUCCESSFULLY RESOLVES SEVERAL OF THE PROBLEMS INHERENT IN THE PRESENT NON-ITERATIVE AFWAL PNS SCHEME. IN PHASE I OF THE PROPOSED TWO-PHASE EFFORT, WE WILL EXTEND THE NONITERATIVE PERFECT-GAS AFWAL PNS SCHEME TO ACCURATELY PREDICT EQUILIBRIUM-AIR FLOWFIELDS AROUND REALISTIC REENTRY CONFIGURATIONS. IN PHASE II OF THIS EFFORT, WE PROPOSE TO EXTEND THE RECENT AXISYMMETRIC FULLY-ITERATIVE PERFECT-GAS PNS SCHEME TO BHUTTA AND LEWIS, AND PROVIDE THE AIR FORCE WITH THE CODE TO STUDY THREE-DIMENTIONAL PERFECTGAS/EQUILIBRIUM-AIR FLOWFIELD AROUND BALLISTIC AND LIFTING REENTRY VEHICLES.
