A survey of the literature on pressure, temperature and foreign gas inlet distortions is made. For interpretation of the influence of inlet distortion on engine stability, a break is made with distortion methods which use temperature or pressure distortion maps. The distortion in the form of temperature contours is transformed to vorticity using appropriate equations derived for both incompressible and compressible flow. A numerical solution of Poisson's equation to describe secondary flow arising from convected vorticity is presented.
