DescriptionEnergy discharge is a novel method for supersonic flight control. Laser energy deposition is shown to be an effective method for drag reduction. A time dependent computational study is conducted to examine the effects of an off-axis laser discharge upstream of an ogive cylinder at Mach 3.4. A perfect gas model is utilized for both laminar and turbulence models. The physics of the interaction of the laser discharge with the shock wave and the ogive body is explained. The effect of the location of the discharge on the side force and drag force coefficients is examined. The streamwise and vertical velocities are compared with an experimental study conducted at Rutgers University's Emil Buehler Supersonic Wind Tunnel.
