An implicit difference scheme solving Euler equations is developed based on NND ideas. Numerical test of diaphragm rupture in one-dimensional shock tube is carried out. The results are compared with those of implicit flux vector fractorization and explicit NND scheme. Extended to axisymmetric Euler equations, this scheme can be used to calculate the transonic flow near M∞=1 for sphere cylinder.
