The Focke-Wulf Fw 44 Stieglitz ("Goldfinch") is a 1930s German two-seat biplane. An early design by Kurt Tank,[2] it was produced by the Focke-Wulf company as a pilot training and sports flying aircraft. It was also eventually built under license in several other countries.

Design and development

The Fw 44 was designed as a biplane with conventional layout and straight, untapered wings. Its two open cockpits were arranged in tandem, and both cockpits were equipped with flight controls and instruments. The Fw 44 had fixed tailwheel landing gear. It employed ailerons on both upper and lower wings. It did not use flaps. It was flown with a Siemens-Halske Sh 14 radial engine.

The first prototype flew in 1932.[1] After many tests and modifications to increase the plane's durability and aerodynamics, the final Fw 44 proved to have excellent airworthiness.

A second version of the Fw 44 was the Fw 44B, which had an Argus As 8 four-cylinder inverted inline air-cooled engine of 90 kW (120 hp).[1] The cowling for this engine gave the plane a more slender, aerodynamic nose.

20 Fw 44s purchased by China were modified for combat missions, and participated in the early stage of the Second Sino-Japanese War until all were lost in action.

The last series version was the Fw 44J, which was sold or built under license in several countries around the world. It was equipped with a seven-cylinder Siemens-Halske Sh 14 radial engine.

Der Typ war bei der Luftwaffe eines der Standardschulflugzeuge für die Ausbildung der Jagdflieger. Einige Erfolge im Luftsport, wie zum Beispiel eine Siegesplatzierung auf der Kunstflugmeisterschaft anlässlich der Olympischen Sommerspiele 1936, wurden ebenfalls mit der Fw 44 erflogen.

Le Focke-Wulf Fw 44 Stieglitz (Chardonneret en allemand) est un avion biplan biplace de sport et d’entraînement allemand de la Seconde Guerre mondiale. Cet appareil qui fit son premier vol au cours de l’été 1932 fut la première réalisation du Dipl. Ing. Kurt Tank chez Focke-Wulf. Il connut un succès remarquable et même si la production exacte est inconnue (entre 1 900 et 3 000 appareils selon les auteurs), il fut indiscutablement l’avion le plus construit de la firme de Brême après le chasseur Fw 190. C’est également un fuselage de Fw 44 qui a été utilisé pour réaliser l’hélicoptère Focke-Wulf Fw 61.
