In order to further explore the application potential of the nitro-rich oxidant DBDN with non-hygroscopic property. Firstly, the synthesis route of DBDN is optimized, and the standard molar enthalpy of formation (ΔfHθm) is calculated according to the measured constant volume heat of combustion (Qv). Then, the ramj software is used to calculate the properties of DBDN in composite modified double base (CMDB) propellant and low signature propellant were studied, and the kinetics of thermal decomposition of ammonium perchlorate (AP) catalyzed by DBDN was further studied by Kissinger equation at the same time. The results show that the Qv and ΔfHθm values of DBDN are -(13525.5±3.28) J·g-1 and -(17.36±0.24) kJ·mol-1, respectively. The optimum synthesis conditions are as follows: the reaction temperature was 65 °C, the solvent was 10:1 EtOH/H2O, and the reaction time wan 5 h. Among them, ramj calculation results show that it is better for DBDN to partially replace AP in CMDB propellant formulation, and the performance gain is obvious when the mass fraction of DBDN is controlled between 8% ~ 14%. On the other hand, in the formulation of low signature propellant, although DBDN can reduce the combustion chamber temperature (Tc) and the tail flame temperature (Te) by 17 times and 11 times as much as ADN respectively, and there is also no HCl gas in the combustion products, it has great advantage in improving low signature, but it also will weaken the energy performance to some extent, so a trade-off between high energy and low signature is required in practical applications. In addition, the Kissinger equation shows that the addition of 10wt% DBDN to AP decreases the activation energy of thermal decomposition of AP by 27.5 kJ·mol-1, which is beneficial to catalyze the thermal decomposition of AP at high temperature, indicating that DBDN has the potential to adjust the burning rate and pressure exponent.
