Measurement and calculation of the ideal detonation velocity for liquid nitrocompounds

Results of experimental measurements are presented for the dependence of th e detonation velocity on the charge diameter for homogeneous nitromethane a nd propylene glycol dinitrate and for the ideal detonation velocities for a llyl nitrate, diethlyene glycol dinitrate, methylene glycol dinitrate, and ethyl nitrate. Literature data on measurement of the dependence of the deto nation velocity on the charge diameter for liquid TNT, nitroglycerin, glyco l dinitrate, and methyl nitrate are collected. It is shown that measured va lues of the ideal detonation velocity are in good agreement with calculated values obtained by the SD method, which uses the equation of state of mate rials at a high pressure (see B. N. Kondrikov and A. I. Sumin, Fiz. Goreniy a Vzryva, No. 1, 1987). A correlation between the ratio of the critical det onation velocity to the ideal velocity and the heat of explosion is obtaine d, which makes it possible to estimate the limiting value of the latter at which homogeneous liquid nitrocompounds lose detonatability.
