摘要
Abstract
In order to explore the effect of aromatic compounds on the combustion performance of CMDB propellant,2,2'-(pro-pane-1,1-diyl)bis(4-(tert-butyl)phenol)(PDBP)was used to prepare HMX-CMDB propellant,and the combustion performance of HMX-CMDB propellants with different PDBP contents was studied using the target line method.The results showed that with the increase of PDBP content,the burning rate and pressure index of HMX-CMDB propellant significantly decreased.For HMX-CMDB propellant containing 7%PDBP,the burning rate at 16 MPa decreased to 8.55 mm·s-1,and the pressure index de-creased to 0.217.Compared with the sucrose octaacetate(SOA),HMX-CMDB propellant containing the same mass of PDBP ex-hibited almost unchanged burning rate in the low-pressure region(8-10 MPa),a further reduced burning rate in the high-pressure region(12-16 MPa),resulting in a lower pressure index.In addition,after replacing SOA with 1%PDBP,the det-onation heat of HMX-CMDB propellant was reduced by only 20 kJ·kg-1.Based on chemical structure analysis,the mechanism of PDBP's burning rate inhibition effect is as follows:the aromatic molecule decompose to form protons and structurally stable radi-cal molecules with conjugated π bonds,and the active protons can react with the active radicals released from the decomposi-tion of energetic molecules in the HMX-CMDB propellant,forming stable structures that mitigate the autocatalytic effect of free radicals,thereby reducing the burning rate.关键词
