Mach 8 Hypersonic Reflected Shock Tunnel Model

Underwrite 100-meter free-piston driven reflected shock tunnels generating Mach 8 airflow at 6,000 Kelvin stagnation temperatures for 5 milliseconds (testing hypersonic re-entry heat shields and scramjet combustor ignition). Model defense aerospace testing charter fees ($280k/shot), and 15-yr IRR.
