Polymer-based rocket propellants are generally referred to as composite propellants, and often identified by the elastomer used, eg, urethane propellants or carboxy- (CTPB) or hydroxy- (HTPB) terrninated polybutadiene propellants. The cross-linked polymers act as a viscoelastic matrix to provide mechanical strength, and as a fuel to react with the oxidizers present. Ammonium perchlorate and ammonium nitrate are the most common oxidizers used nitramines such as HMX or RDX may be added to react with the fuels and increase the impulse produced. Many other substances may be added including metallic fuels, plasticizers, stabilizers, catalysts, ballistic modifiers, and bonding agents. Typical components are Hsted in Table 1.

This method has hmitations in the far field where the peak incident overpressure is less than 4 kN/m" (0.5 psi). In this region, local terrain and weather effects become significant.

Particles larger than 100 im fall through the atmosphere so rapidly that turbulence has less chance to act upon and disperse them. The trajectories of such particles are treated by a ballistic approach. 

At low temperatures, in a sample of very small dimensions, it may happen that the phase-coherence length in Eq.(3) becomes larger than the dimensions of the sample. In a perfect crystal, the electrons will propagate ballistically from one end of the sample and we are in a ballistic regime where the laws of conductivity discussed above no more apply. The propagation of an electron is then directly related to the quantum probability of transmission across the global potential of the sample. 

As for the coherent length in CNTs, a very interesting paper has been published from the group at the Georgia Institute of Technology about the conductance of individual MWCNTs [34], They have observed the quantisation of conductance by changing the distance between the two electrodes. This result indicates ballistic conduction in a CNT, which suggests the formation of stationary waves of electrons inside CNTs.
