Abstract
A flow fence for a turbo fan jet engine, as taught by Stein et al. in U.S. Pat. No. 3,841,790, is modified by the provision of serrations about its internal circumference. Thus, when the modified flow fence is inserted into or removed from the flow field, a more gradual transition occurs in the flow thereby improving surge margins.
