Abstract

This paper describes an investigation of theaerodynamic characteristics of collectively variableincidence wing tips at low speeds. Theoreticalconsiderations supported by experimentalmeasurements suggest that the use of articulatedtips which can be rotated to a high incidence forlow speed flight will decrease sensitivity to gusts.Furthermore, windtunnel measurements demonstratethat the use of very high tip incidences can producean increment in maximum overall lift coefficient forsome wing configurations. Another featureinvestigated is the possibility of utilising thelift increment for the purposes of direct liftcontrol. The use of a radio controlled model to testthe practical viability of the concept isdescribed.
