A detailed chemical kinetic mechanism for hypergolic ignition of N2H4 in a N2O4-NO2 gas mixture has beenconstructed. In this mechanism, the hypergolic ignition is mainly caused by the sequential reactions of H atomabstraction from N2Hm by NO2: N2Hm+NO2=N2Hm-1+HONO/HNO2(m=4～1). Although the first step oftheHatom abstraction (m=4) is endothermic, consecutive abstraction reactions form=3, 2, and 1 are exothermic,and especially heat release by the reaction ofN2H+NO2=N2+HONO(m=1) is large because of N2 production.Temperature rise caused by the heat release accelerates the endothermic initiation reaction (m=4). This thermalfeedback is responsible for the hypergolic ignition at low temperatures. Because no experimental and theoreticalinformation is available on these reactions, rate coefficients were evaluated on the basis of transition state theory,unimolecular rate theory, and master equation analysis with quantum chemical calculations of potential energycurves. In addition, reactions of N2H4 with N2O4 isomers were also examined. The present kinetic mechanism canexplain gas-phase hypergolic ignition of N2H4/NTO mixtures at temperatures down to 200 K. |
