Abstract

An investigation of both an experimental and theoretical nature has been conducted into the use of a subsonic conventional ejector as a thrust augmentor. A new effectiveness performance parameter, EN, was derived in this investigation and has proved a useful tool in comparing different thrust augmentor designs. Moderate ejector diffuser area ratios, around 1.5:1, were round to he more favourable for thrust augmentation. This dis(')very proves a new concept in ejector augmentor design which is more suitablc in airfield applications.
