Aerodynamic Model Tests of Exhaust Augmentors for F/A-18 Engine Run-up Facility at RAAF Williamtown - Summary Report

Abstract

Model tests of the air cooled exhaust augmentors proposed for the F/ A-18 engine ground run-up facilities at RAAF Williamtown were undertaken, to confirm satisfactory aerodynamic behavior of the augmentor designs and to provide data for optimizing certain aspects of the designs. The tests were carried out on 1/45 scale models, using an unheated air jet to represent the engine exhaust. Geometric features were identified which had important influence on augmentor duct flow symmetry and the cooling flow augmentation ratio. Keywords: Thrust augmentor nozzles; Convergent divergent nozzles; Thrust augmentation; Afterburners; Jet fighters; Attack bombers; Exhaust systems; F/A-18 Aircraft; F404 Engine; Axial flow turbofan engines; Aerodynamic characteristics; Australia.
