Laser Ignition of Titanium
Abstract
This program was directed towards the determination of using a laser as an ignition source for titanium combustion studies. A sample of titanium was located downstream from a subsonic nozzle with the edge facing the flow. The front, upper tip of the sample was ignited and allowed to burn freely aided only by the transport of oxygen by the wind tunnel. Although the pressure was ambient the air was delivered at 90 - 500 F and flow rates from Mach number .2 to Mach number .7. Sustained combustion was obtained at low Mach numbers and high temperature but not at low Mach numbers and low temperatures. The low Mach number burns were more severe than the high Mach number burns, i.e., more metal consumed before flowout. In all cases the fire progressed laterally but not significantly in the vertical direction.
