Steering in Supersonic Flow via Laser Breakdown: Measurements for a Tethered Cylinder-Cone Conference Paper uri icon

abstract

  • The aerodynamic response to laser energy addition is measured for a tethered cylinder-cone in supersonic Mach 2.6 flow. The subsequent recoil due to surface ablation and air breakdown is directly observed via position measurements from which the net lateral impulse is calculated. Results indicate that laser ablation yields 5 times larger impulses, compared to air sparks, for approximately 30% less energy input. The influence of air sparks, however, can be observed over a larger volume compared to ablation. In the region interrogated by air sparks, a transition from the shock dominated to thermal spot regime is not observed. 2013 by Princeton University.
