Description

Scheibe Bergfalke IV

The Bergfalke IV with a blown Plexiglas canopy. and a new wing of Wortmann section giving improved performance. The nose section on the Mk IV is a moulded glassfibre shell.Construction of the prototype Bergfalke IV began early in 1969 and the first flight was made a few months later. The cantilever mid-wings are of all-wood construction with a fabric-covered plywood skin; the single laminated beechwood box spars are joined at the fuselage centreline with a single vertical pin. The ailerons and Schempp-Hirth air brakes are also of wood. Like previous versions, the welded steel tube fuselage is fabric-covered, the nose section on the Mk IV being a moulded glassfibre shell. The tail unit is of wooden construction, the tailplane being mounted on the fuselage forward of the fin; there is a Flettner trim tab in the starboard elevator.

Bergfalke IVM

Scheibe themselves were test flying another powered version of the Bergfalke IV early in 1976 with a 52hp Hirth 0-28 ‘flat twin’ engine mounted on a retractable pylon aft of the cockpit and driving a two-bladed fixed-pitch tractor airscrew; the engine can be raised and lowered into the fuselage electrically in less than 20 seconds, retracting behind closed doors.
