BFW M.37

The Messerschmitt Bf 108 ''Taifun'' (English: " Typhoon") was a German single-engine sport and touring aircraft, developed by Bayerische Flugzeugwerke in the 1930s. The Bf 108 was of all-metal construction.

Design and development

Originally designated the M 37, the aircraft was designed as a four-seat sports/recreation aircraft for competition in the 4th ''Challenge International de Tourisme'' (1934).Schulz, R. and W. Pleines
"Technical Memorandums No. 760 - Technical Aspects of the 1934 International Touring Competition (Rundflug)."
''National Advisory Committee for Aeronautics,'' December 1934. Retrieved: 13 March 2010.
/ref> The M 37 prototype flew first in spring 1934, powered by a 250 PS (247 hp, 184 kW) Hirth HM 8U 8.0 litre displacement, air-cooled inverted- V8 engine, which drove a three-blade propeller.

Although it was outperformed by several other aircraft in the competition, the M 37's overall performance marked it as a popular choice for record flights. Particular among these traits was its low fuel consumption rate, good handling, and superb takeoff and landing characteristics.

The Bf 108A first flew in 1934, followed by the Bf 108B in 1935. The Bf 108B used the substantially larger, 12.67 litre displacement Argus As 10 air-cooled inverted V8 engine. The nickname ''Taifun'' (German for "typhoon") was given to her own aircraft by Elly Beinhorn, a well-known German pilot, and was generally adopted.Smith 1971, pp. 36–37.

Operational history

Soon after the first production aircraft began to roll off the assembly line in Augsburg, several Bf 108s had set endurance records.

The Bf 108 was adopted into Luftwaffe service during World War II, where it was primarily used as a personnel transport and liaison aircraft. The aircraft involved in the Mechelen Incident was a Bf 108.

Production of the Bf 108 was transferred to occupied France during World War II and production continued after the war as the Nord 1000 ''Pingouin''.

Variants

;Bf 108A
:Initial version designed in 1934 for use in Challenge 1934. Six were built with the Hirth HM 8U, one other initially had a 220 PS (217 hp, 162 kW) Argus As 17B inline engine and later a 160 PS (158 hp, 118 kW) Siemens-Halske Sh 14 radial.
;Bf 108B
:Revised version, built from late 1935. The prototype had a Siemens-Halske Sh 14A radial, but production machines used the 240 PS (237 hp, 177 kW) Argus As 10C or the 270 PS (266 hp, 199 kW) Argus As 10E. A quadrant-shaped rather than rectangular rear window, tailwheel replacing skid, revision of shape of empennnage and removal of tailplane upper bracing.
;Bf 108C:Proposed high-speed version, powered by a 400 PS (395 hp, 294 kW) Hirth HM 512 engine. Probably not built.
;Me 208
:Improved and enlarged version with a retractable tricycle landing gear. Two prototypes were built by SNCAN (Nord) in France during the war. After 1945 Nord continued its production as the Nord Noralpha.
; Nord 1000 ''Pingouin''
:Bf 108 built during and after the war by SNCAN in France; followed by the Nord 1001, that had only minor variations and the Nord 1002, which used a Renault engine.
; Nord 1100 ''Noralpha''
:Bf 108 derivative built after the war by SNCAN in France with tricycle landing gear and a Renault engine.

* Royal Air Force operated four Bf 108s, under the designation "Messerschmitt Aldon", which were impressed from private owners on the outbreak of the war. Reportedly they were the fastest light communications aircraft the RAF had, but they were also sometimes mistaken for Bf 109s although there is no record of any fatal encounters. Postwar, 15 more captured Bf 108s flew in RAF colours until the mid 1950s.

* United States Army Air Corps - in early 1939, a single Bf 108B was purchased for $14,378 and designated XC-44. It was used only by the US air attaché in Berlin. In November 1941, the aircraft was assessed as unserviceable. The airframe was seized by the Nazi government, following the commencement of hostilities, in December.
