Web14. . 2. The Rocket Equation. We can now look at the role of specific impulse in setting the performance of a rocket. A large fraction (typically 90%) of the mass of a rocket is propellant, thus it is important to consider the change in mass of the vehicle as it accelerates. Figure 14.2: Schematic for application of the momentum theorem. WebQuasi-static testing results for PBXN-5 at the temperature endpoints of +/- 50°C and at two different strain rates are shown in Figure 4. Each plot has traces from two different tests at each strain rate, illustrating the sample-to-sample variability. Plots at -25°C, 0°C, and 25°C are not shown, but had similar characteristics. 0 10 20 30 40 50

A pyrotechnic is a mixture of ingredients of fuel and oxidant (e.g. BKNO3) producing a chemical reaction occurring at a burn rate typically less than 1000 meters per sec (m/s). The reaction does not reach sonic velocities in the unreacted material; therefore, does not produce a detonation.
