Broburn Sailplanes Wanderlust
 
 BroWund-01
 
The Broburn Wanderlust was a small, wooden, single-seat glider designed in the United Kingdomand built by T. E. Brown and K. W. Radburn (as Broburn Sailplanes Ltd, Woodley), two employees of Miles Aircraft, immediately after World War II.
 
It was a single-seat, all-wood, shoulder-wing aircraft, with a short span for a glider of 34 ft (10 m) though with an aspect ratio of over 15. The wing of the Wanderlust was built around a single spar, which with plywood skin around the leading edge formed a torsion box. Behind the spar the wing was fabric covered. There was 4° of dihedral and 2° of washout. The trailing edge was spanned with aerofoil section flaps, split into two equal sections. Inboard, these acted as simple flaps; outboard, additionally, as drooping ailerons. The two NACA airfoil sections used in the wing were chosen because they have centres of pressure that vary little with the angle of incidence, which increases when the flaps are deployed. The Wanderlust also had upper surface spoilers hinged on the wing spar at about quarter span.

The rest of the Wanderlust was plywood skinned, with a cockpit which could be open or enclosed in a bubble Perspex hood. The pilot's head is raised well above the wings and fuselage under a hood. A seat type parachute is provided, with a radio as possible additional equipment. The fuselage tapered aft, with the tailplane mounted on top and the small fin behind it. The elevators, with individual trim tabs, moved either side of the fin and the rudder was hinged behind their trailing edges. Both elevators and rudder were horn balanced. The Wanderlust landed on a pneumatically-mounted central skid. A cut motorcycle inner tube encased in canvas provides an inflatable shock absorber.

Despite hopes of marketing the Wanderlust in finished and in kit form, only one was made. This was first flown in 1947, in the hands of Miles Aircraft's Chief Test Pilot, Hugh Rendall, and flown by many pilots including Lorne Welch. It was in at store at RAE Farnborough about 1970. In 1993, having been in storage at Farnborough for some years, it was bought back to Woodley for restoration in the Museum of Berkshire Aviation by its owner Pat Pottinger and one of its original creators Ken Radburn.
