High Angle of Attack Analysis of Cascade Fin in Subsonic Flow

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)

Abstract

Grid fins are unconventional lifting and control surfaces consisting of an outer frame supporting an inner grid of intersecting small chord planar surfaces. Cascade fins are a new category of grid fins. Unlike grid fins, cascade fins do not have cross members. In the present work, a sequence of simulation results obtained for comparative analysis of cascade fins versus flat plate (FP) for different angles of attack (\(\alpha \)) is presented. The results indicate an overall increase in lift force compared to flat plates at all angles. The results are in agreement with the experimental data and indicate that cascading effect leads to a delay in flow separation and thus delayed stall.
