| Abstract: | Measurements are reported on detonations of homogeneous liquid nitric oxide initially at T = 119 K, /rho//sub o/ = 1.28 g/cm/sup 3/. Plane-shock initiation in mirror-covered wedges demonstrated detonation in preshocked material (superdetonation) that overtook the smooth input shock. Its transverse irregularities continued in the unsupported detonation. The input shock ran ca. 3 mm at U/sub I/ = 3.8 /plus minus/ 0.2 km/s. Behind it the fluid had u/sub p/ = 0.89 /plus minus/ 0.02 km/s, p = 4.3 /plus minus/ 0.03 GPa, /rho/ = 1.67 /plus minus/ 0.03 g/cm/sup 3/, and the superdetonation had D*/sub lab/ /approx/6.9 km/s. In 356-mm long graphite tubes with 25.4-mm inner diameter, measured detonation velocity is D = 5552 /plus minus/ 3 m/s. Failure diameter in graphite is below 8 mm. Free-surface velocities of 1- and 2-mm aluminum plates terminating the detonation axis were near 1.5 km/s approximately as predicted for CJ flow at D/sub /infinity// = 5564 m/s, u/sub p/ = 1.34 km/s impinging on aluminum. Electronic streak photography at d = 20.6 mm in brass registered a smoothly convex detonation front with apparent brightness temperature of 1735 /plus minus/ 40 K as it reached an end window asynchronously. 20 refs., 5 figs., 3 tabs. |
