1、5n . 12 APRIL 1988 MILITARY SPECIFICATION IGNITER, JET ASSISTED TAKE-OFF JATO) PROPULSION SYSTEM GENERAL DEVELOPMENT SPECIFICATION FOR This specification is approved for use within the Naval Air Systems Command, Department of the Naw, and is available for use by all departments and agencies of the D
2、epartment of Defense. 1. SCOPE 1.1 Purpose. 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 app
3、lications (see 6.1). Implicit within this specification are requirements for the shipping container design. 1.2 Igniter types. Igniters covered by this specification are of two types (see 6.2.1): Type I: Integral igniter Type II: Non-integral igniter Type I ,gniters are designed to be installed in t
4、he 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 fr
5、om the rocket motor. 1.3 Integrated programs. If the igniter is being developed in conjunction wth a rocket motor, considerable savings in effort and resources may be achieved by integrating the requirements of MIL-R-85880 and this specification. 2.
