The paper gives the performance characteristic of a new type modified double base solid propellant, and it is compared with the traditional double base propellant.

The theoretical calculation results of energy characteristics for smokeless modified double-base propellant with ACP show that ACP can decrease the energy of the propellant.

Elastomeric modified cast double base (EMCDB) propellant, which has good mechanical properties and plateau burning-effect, has been first successfully prepared by granule-casting in China.
