GROUND EFFECT MACHINE INVESTIGATIONS AT THE UNIVERSITY OF WICHITA: FINAL REPORT SUMMARIZING THE TEST PROGRAM AND DATA OBTAINED

Abstract

Tests were performed on a family of circular, annular jet ground effect machine models. The testing, conducted in a low speed wind tunnel, investigated such parameters as slot width, convergence angle of the annular jet, model height above the ground, and model angle of attack using operating pressure ratio and forward velocity as test variables. Values of lift, drag, and picthing moment were recorded along with pressure measurements on the model outer surface, base plate, and ground board. Total and static pressures were also measured at 3 locations in the annular nozzle. (Author)
