| Abstract: |
| mathematical expression R’= KR.R0(1 +α)△t-1 is proposed in thispaper to predict thrusts varying with duration and temperature in storage of solidpropellant rocket engine, according to statistics of massive test data. The expressionhas been verified with calculations and tests. |
| Key words: olid propellant rocket engine Thrust Double base propellant Ballistic properties of propellant |
