Abstract:

A study was made of the behavior of W under condiions encountered in the exhaust stream from solid-propelant rocket motors, with parculr emphasis on the effet of alumina. No significant reaction was found between W and moten l2O3 under these conditions. The following reactions, listed in decresing order of importance, were observed between W and the gaseous exhaust contituens 91 3H2O W yields WO3 3H2, 3CO2 W yiels WO CO, 3 HCl ALO3 32 W yies 2All3 32 WO2cl2 92 H AND THE TRANSFER OF W through liquid Al2O3. OTHER GSEOS CONTTUENS, CO, HCl, H2, and N2, did not rect wth W. An increase of HCL IN THE EXHAUST GAS DECREASED THE AMOUNT OF Al2O3 deposted on nozzle and jetevtor rfaces. study of the effect of nozzle liner thickness on reistance to theal shock indicated that an intermedite thickness range exts in which failre by theral shock is most likely to occur.
