MIL-I-85889

Abstract

This specification establishes the minimum requirements for the design, verification, and qualification of JATO rocket motor ignition systems, hereinafter referred to as "igniters." The igniters are components of solid propellant rocket motors for JATO applications (see <a>6.1</a>). Implicit within this specification are requirements for the shipping container design. <br>Igniters covered by this specification are of two types (see <a>6.2.1</a>): <br>Type I: Integral igniter <br>Type II: Non-integral igniter <br>Type I igniters are designed to be installed in the rocket motor at the time of manufacture and are designed to remain there for their entire life cycle. Type II igniters, on the other hand, are designed to be installed in the rocket motor by the user only at the time of use. Type II igniters are normally handled, shipped, and stored separately from the rocket motor. <br>If the igniter is being developed in conjunction with a rocket motor, considerable savings in effort and resources may be achieved by integrating the requirements of MIL-R-85880 and this specification. <b><u>Intended Use:</u></b> The solid propellant rocket motor igniters described herein are JATO system components. The JATOs are used to assist manned aircraft, targets, and remotely piloted vehicles during takeoff. <br>
