Abstract
The present paper presents recent experimental results on the Laser‐Supported Directed Energy “Air Spike” — DEAS in hypersonic flow achieved by the Laboratory of Aerothermodynamics and Hypersonics — LAH, Brazil. Two CO2 TEA lasers, sharing the same optical cavity, have been used in conjunction with the IEAv 0.3m Hypersonic Shock Tunnel — HST to demonstrate the Laser‐Supported DEAS concept. A single and double laser pulse, generated during the tunnel useful test time, were focused through a NaCl lens upstream of a Double Apollo Disc model fitted with seven piezoelectric pressure transducers and six platinum thin film heat transfer gauges. The objective being to corroborate previous results as well as to obtain additional pressure and heat flux distributions information when two laser pulses are used.
