Aerospace and Propulsion
Solid rocket propulsion systems having any of the following:
| Reference | Parameter | Threshold |
|---|---|---|
| 9A007.a | Total impulse capacity | > 1.1 MNs |
9A007.aTotal impulse capacity exceeding 1.1 MNs;
9A007.bSpecific impulse of 2.4 kNs/kg or more, when the nozzle flow is expanded to ambient sea level conditions for an adjusted chamber pressure of 7 MPa;
9A007.cStage mass fractions exceeding 88% and propellant solid loadings exceeding 86%;
9A007.dComponents specified in 9.A.8.; or
9A007.eInsulation and propellant bonding systems, using direct-bonded motor designs to provide a "strong mechanical bond" or a barrier to chemical migration between the solid propellant and case insulation material.
