| Abstract: | Instantaneous equilibrium pressure method is used in this paper to analysis the internal ballistics of pyrogen-type igniters. A concept of igniter heat loss coefficient is also presented. The relationship among igniter charge mass, nozzle area and igniter chamber pressure is also established. The calculation results are satisfactory with test date. Two important conclusions are drawn from the caculation results. One shows that the ignition acceleration basket is an important and reasonable part in igniter, another shows a kind of optimal igniter charge configuration. |
