A 5: aka Focke-Kolthoff-Wulf-Taube A.5Ī 6 - 1914 Taube-style 2-seat monoplane, 50 hp Argus Typ 4 * Some sources say A 5 airframe completed in 1912 Bruno Lange calls this design Ente (with no designation)Ī 5 - 1913* Taube-style 2-seat monoplane, 50 hp Argus Typ 4 * Some sources say F 4 completed ( klappte) in 1912 F 4: Retroactive designation, aka Kolthoff-Focke A IV Bruno Lange calls this the A.4 (A.3 being a pusher monoplane)į 4 - 1913* canard monoplane, 40 hp NSU engine, span 12 m with Kolthoff and Wulf, proved underpowered* Speculative (retroactive desig.), aka ' Bremer Ente' (' Bremen Duck')Ī 3 - 1912 Taube-style 2-seat monoplane, 1 x 8 hp NSU engine * Presum'ly powered by 451cc 1-cyl (from NSU 6/8 PS van) F 2: Some say motor glider, taxi-capable only, wing 20 m2 * Glider with successive, different sizes of wingį 2 - 1909-1910 canard a/c, 1 x 8 hp NSU engine,* proved unflyable A 1: Built with brother Wilhelm, Patent nr. The RLM reserved the '39' number for DFS (applied to the 1935 Delta IV flying-wing).Ī 1 - 1908 homebuilt hang glider ( Drachenflieger) Henrich not involved in any way with the 1909 ' Ente'. The design was an evolution of Wilhelm Focke's 1909 'Ente' (built in the Potsdam workshop of Dr Edmund Rumpler). 'Missing' Focke-Wulf designations may cover licensed aircraft, eg: the Cierva C.19 autogyro Albatros L75, L78, L101, and L102 variants (see Fw 55) and Heinkel HE 5 and HE 9 float monoplanes. To save space, I've used 'c/n' rather than 'WerkNr' for construction numbers.Ībbreviations include DVS for Deutsche Verkehrsflieger-Schule (German Civil Aviation Pilot Training Center). But the company doesn't seem to have taken this up - there are ' Heuschrecke' (' Grasshopper') references to 'Fw C.30' (and even Fw C.19a) but 'Fw 30' seems to be a post-war rationalization. While 'Fw 39' was not an RLM number, Focke-Wulf was assigned '30' as 8-30 for the licensed Cierva C.30 autogyro ('8' being the RLM designator for powered aircraft). Under this system, Focke-Wulf Flugzeugbau GmbH was given the identifier code 'Fw' and assigned blocks of numbers. The Focke-Wulf works system of designation continued until 1932 when it was replaced by a national numbering system (begun by the Heereswaffenamt, made mandatory in 1933 by the Reichsluftfahrtministerium (RLM). The S 39 is also sometimes dubbed the 'Fw 39'. But the suffix is odder still since there doesn't seem to have ever been an 'S 39A' (unless this was an unknown, unbuilt project?). Ignoring the early capitalization, the omission of the role letter is odd. For no obvious reason this prototype is often referred to as the Focke-Wulf 39B. One anomaly is the S 39 reconnaissance monoplane. After 1932, suffixes were capital letters. Until 1932, this suffix was a small letter. A few Focke-Wulf designations numbers were non-consecutive (eg: the S 1 and S 2 trainers). I have chosen to standard designations with a space (eg: A 7). Some sources display early Focke-Wulf designations with hyphens (eg: A-7), others without spaces (eg: A7). But these are guesses only (although Wasser is a very safe guess). It's tempting to suggest Austausch (Convertible), Flugzeug (Aircraft), Große Leichtflugzeug (Large Light aircraft), Kampf (Combat), Spezial (Special). This designation system was first used on the A 7 of 1921 and then applied retroactively to Focke's previous aircraft designs.Īlas, I do not know what the prefix letters stand for. In pre-WWII publications, the type numbers are sometimes given in Roman numerals. Werner Naumann.Įarly Focke-Wulf aircraft designs received works designations consisting of a role letter - A, F, GL, K, S, and W - followed by a type number (which were assigned more or less consecutively). Henrich Focke then joined forces with Georg Wulf and Dr. The first powered design involving Henrich was the 1910 ' Bremer Ente' (' Bremen Duck') canard aircraft (which proved too heavy to fly). Henrich Focke built at least one aircraft with his brother, Wilhelm Focke.
