Abstract
This article explores, theoretically and experimentally, Coanda effect and upper surface blowing over an annular wing. Also, presented are a simple mathematical/empirical model and an experimental strategy to evaluate lift generated by a blown-annular wing. It has been shown that the wing is capable of deflecting the flow by ∼90° with an efficiency of ∼61 per cent with reference to the undeflected horizontal thrust from the source. The analytical review and experimental data presented will enable an aircraft designer to deduce this particular powered-lift system for V/STOL applications at the preliminary design stage.
