Study on detonation velocity deficits of bending flexible detonation fuses

In order to study the detonation velocity deficits of bending flexible detonating fuses, a physical model and a theoretical mathematical equation of detonation velocity deficits for bending flexible detonation fuses were established based on the detonation wave's corner effects and delay time phenomenon by using non-dimensional analysis method. Besides, a semi-empirical formula of detonation velocity deficit for bending fuses in the same charge size was obtained through experiment and curve fitting. The result shows that an exponential relationship between the detonation velocity deficits and reciprocal of curvature radius.
