| Abstract: | The concentration profiles of functional components of NA polyester deterrent and nitroglycerine in 11/7 modified single base propellant were investigated by FTIR microspeetroscopy. The results show that the NA polyester concentration decreases in the near surface of propellant exponentially from the surface inwards, which is in accord with the second Fickian diffusion model, the diffusion depth is about 220μm. The variation curve ofnitroglycerine concentration reveals a parabola along radius, the diffusion depth is about 320μm. |
