Ballistic exit

For g = 0 we obtain, again as a short-time approximation, the result n (t) = n0 — at corresponding to ballistic exit (zero-order kinetics). 

The most important attributes of this invention are high impulse performance coupled with high exit temperature on primary combustion and favorable boron species in the primary motor exhaust. The system is also insensitive to impact and possesses excellent thermal stability at elevated temperatures. Additionally, the system is readily castable since the addition of solid oxidizers is not required. Further, high flexibility in the ballistic properties of the gas generator can be achieved by the addition of solid oxidizers such as ammonium nitrate, ammonium perchlorate, hydroxylammonium perchlorate, potassium perchlorate, lithium perchlorate, calcium nitrate, barium perchlorate, RDX, HMX etc. The oxidizers are preferably powdered to a particle size of about 10 to 350 microns [13]. 

One solution is to place the reactor cyclones very close to the riser outlet. This is the vented riser design offered by UOP — Figure 22. Catalyst from the end of the riser impacts the head of the reactor which now acts as a ballistic separator. The reaction mix turns 180 degrees as it leaves the riser to exit quickly through the cyclone inlets positioned right next to the riser. 

Ballistic tip bullets (rapid expansion) had the highest fragmentation rate 141 fragments 11 inches from the wound channel. In one carcass, a fragment was found 14 inches from the exit wound. ...
