Rebuild Axial Symmetric Density Field of Blunt Cone Model in Free-Flight Ballistic Range

摘要

Axisymmetric density field of the blunt cone model is measured in the free-flight ballistic range utilizing holographic interferometty. The paper introduces a new method that compared with the experimental interference fringes and the computational one for increasing the definition of reading interference fringes. A rebuilt technology for density field is used to obtain the full flow field density distribution that provides an experimental basis for model design and CFD. It is also significant to put the CFI technique further forward.
