Abstract

Effects of several liquid burning rate catalysts on rheological properties of composite rocket propellants on the basis of hydroxy‐terminated polybutadiene as a binder and ammonium perchlorate as an oxidizer have been examined. Theoretical explanation of the observed effects of liquid catalysts on certain rheological properties of the mentioned propellants are given. Laboratory procedures for synthesis of used catalysts are described. The results of physico‐chemical characterization of synthesized catalyst are also presented.

Burning rates of phenol-formaldehyde composite propellants based on NH4CI04, KCIO4, NaNOa, and KNO a oxidisers are measured under the pressure of nitrogen at 1-95 atm. The burning rate laws of the type (P[r) = (a + bP) and (P/r) = (a + bP21 a) are tested. It is revealed that the latter gives a super
