Abstract: Exploratory tests have been carried out to determine the possibility of using a front flap to augment static lift and recovered thrust of power augmented ram platforms. Pressure distributions, measured under a model-scale platform, demonstrate a strong effect in response to the front flap deflection. It is found that both lift and thrust recovery can be nearly doubled in some configurations by deploying the front flap.

Keywords: power augmented ram; PAR platforms; ground effect vehicles; front flaps; aerodynamics; static lift; thrust; front flap deflection.
