The experimental and numerical investigations of an opposing jet through an extended nozzle are described. The opposing jet through the extended nozzle is a new type of thermal protection de- vices combining an opposing jet and a forward facing spike. The experimental measurements of the heat flux distribution on a hemispheric- cylindrical blunt test model were conducted in a free piston shock tunnel in Kyushu University. The present test flow condition is 5,600 m/s and Mach number at 6.6. The shock tunnel testing demonstrates capabilities of this device reduc- ing the heat flux up to 92% in hypersonic and high enthalpy flow. In addition, axisymmetric Navier-Stokes numerical simulations were car- ried out. The numerical simulations show reduc- Tion of both aerodynamic heating and drag with precise explanations of the flow field structure.
