PolyNIMMO showed a good foreground as binder in LOVA propellant, and its oligomers might be used as plasticiser for nitrate ester binders, which also was an important studied issue.

Aim\ To study the effect of a new type of LOVA formulation on the combustion behaviors.

The experiments show that DIANP propellent charge not only has good interior ballitic property, but also overcome the defect of porous propellant 125 charge, such as low energy, high hygroscopicity, unreasonable charge combustion character, and improve the high erosion and the serious muzzle flame existed in the present propellant charge containing high nitrog.

Study on Exterior Compatibility of Propellant with Depleted Uranium and Plating;

Research on the Packaging Box Design of Propellant Sample;

Technical Analysis on the Making of Rocket-Firework Powder from Expired Propellants;

Study on Performance of LOVA Propellants;

Interrupted-burning phenomena of different propellants such as triethyeneglycol dinitrate(TEGDN),double-base propellants,nitramine propellants and single-base propellants ignited by plasma are studied by interrupted-burning setup.

The mechanical properties of single-base propellants with nitrogen content of 11,12,13,14 percent of weight and double-base propellants consisting of nitrocellulose(NC) and nitroglycerin(NG) were simulated by molecular dynamics(MD) method.

Study on the clear burning gun propellant;

The static and dynamic mechanical properties of gun propellants containing NC, RDX and polyether-urethane PET with mixed nitrate easter as plasticzing agent (JMZ gun propellants) were tested by DMA and materials tester at different temperatures.

The thermal decomposition performance of JMZ gun propellants containing PET(copolyether of tctrahydrofuran and epoxy ethane) binder and their related compositions was studied by TG and DTA.
