The Broburn Wanderlust is a single seat British glider . It was developed and built in Woodley by TE Brown and KW Radburn, two employees of Miles Aircraft . The name of their company, Broburn, is an acronym derived from the components of their surnames. The first flight was on March 1, 1947 by Miles' chief test pilot Hugh Kendall. It stayed with this single copy.
description
The Wanderlust is a relatively small single-seater that was designed for cross-country flights . The wing loading is comparatively high in order to achieve sufficient flight stability even in strong winds and a high flight speed. The aircraft is designed as a wooden shoulder wing wing . The wing in Holm-rib construction have a simple box beam and a planked with plywood Torsionsnase and fabric-covered ribs fields. Over the entire span, the trailing edge is a flap - aileron combination , which is divided roughly in half on each side, with the inner half acting as the flap and the outer half as the aileron. This flap complex is designed as an “external flap” similar to a Junkers double wing attached to support arms protruding from the profile contour. The flap function is operated via a handwheel in the cockpit, while the ailerons are also lowered to increase lift. To reduce the negative turning torque , the deflections of the ailerons are strongly differentiated by the actuation mechanism.
The surviving aircraft is on display in the Museum of Berkshire Aviation in Woodley.
