Solid rocket propulsion systems having any of the following: N.B.: SEE ALSO 9A107 AND 9A119. a. Total impulse capacity exceeding 1,1 MNs; b. Specific 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; c. Stage mass fractions exceeding 88 % and propellant solid loadings exceeding 86 %; d. Components specified in 9A008; or e. Insulation 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. Technical Note: ‘Strong mechanical bond’ means bond strength equal to or more than propellant strength.
