Focke-Wulf S 24

The Focke -Wulf S 24 " Lapwing " was a two-seat, aerobatic biplane sport aircraft, the Focke- Wulf Flugzeugbau AG in 1928. A special feature of the aircraft were the fold-down back wings. Thus, the plane could be removed or transported from an ordinary passenger car.

History

The Focke -Wulf S 24 was an after-work project of designers Paul Klages and Wohlberg, who worked at Focke Wulf and designed the aircraft for Gerd Archgelis. End of 1929 this became an official pattern of Focke Wulf. With a version with additional fuel tanks Edzard and Max Middendorf presented on 20 August 1929 coverage world record in its class of 1601 km. Gerd Achgelis won 1931 on this type of aircraft ( an S 24c), the German championship in aerobatics. A total of 31 machines of this type were sold, including some to China and as a demonstration machine to Brazil.

Also, was the Focke -Wulf S 24 godfather of the available today -it-yourself microlight Platzer Lapwing.

Construction

  • Type: Single-engined light aircraft in lightweight construction
  • Wings: Distortion, einstieliger biplane with straight, unstaggered wings. Upper and lower wings of the same size and with the same floor plan. Unlike many other biplanes this time, each upper wing half was not attached by an N- stem above the fuselage, but by two stalks arranged like an inverted V and a further single stalk behind the front cockpit. With the lower wing, the upper wings are connected by an N- stem. The wings are cross- braced with double wires.
  • Hull: Hull planking as welded steel tube trellis, covered with fabric, only in the area of the motor with aluminum.
  • Suspension: rigid normal chassis. Each main wheel of split axle which is raised in the middle and hinged to a three-legged bracket under the fuselage. Rigid tail skid.
  • Engine: A Siemens & Halske Sh 13 air-cooled 5-cylinder radial engine. From this engine there were different versions of 68 hp (50 kW) to 82 hp ( 60 kW). He drove to a rigid two-bladed wooden propeller.
