The Akaflieg Berlin B4 F.F. was a single-seat aircraft built in Germany in the early 1930s. It was a high-wing monoplane of all-wood construction with fabric-covered foldable wings [1]
In 1931 the Deutsche Luftfahrt-Verband e.V. (DLV) opened a competition for an inexpensive light aircraft. Two entries were put forward; Akaflieg Berlin's B4 F.F. (D-2229) and Dipl.-Ing. Hermann Mayer's MM-1 (D-2230), with both aircraft exhibited at the 1932 Deutschen Luftsport-Ausstellung (DELA) in Berlin. [2]
Like the Mayer MM-1 the B4 F.F. was constructed at the DLV workshops in Adlershof. Design took eight months and construction a further nine. [2]

General characteristics
Performance
The Tupolev Tu-80 was a Soviet prototype for a longer-ranged version of the Tupolev Tu-4 bomber, built after World War II. It was cancelled in 1949 in favor of the Tupolev Tu-85 program which offered even more range. The sole prototype was used in various test programs before finally being used as a target.
The Tupolev Tu-75 was a military transport variant of the Tu-4 bomber, as was a similar airliner, the Tu-70, both using a new, purpose-designed fuselage. The first Soviet military machine of this class, it was equipped with a rear fuselage loading ramp. It was not placed into production because the VVS decided it would be cheaper to modify its existing Tu-4s for the transport mission and to use its existing Lisunov Li-2 and Ilyushin Il-12 transports.
The LWS-6 Żubr was a Polish twin-engined medium bomber, produced by the LWS factory before World War II. It was produced in limited numbers and was used for training only, as it was inferior to the contemporary PZL.37 Łoś design.
The Avro 604 Antelope was a British light bomber which was designed and built in the late 1920s to meet a requirement for a light bomber to equip the Royal Air Force, competing against the Hawker Hart and the Fairey Fox II. It was unsuccessful, the Hart being preferred.
The Darmstadt D-22 was a sports-plane of Germany, designed and built by Akaflieg of Technische Universität Darmstadt.
The Rohrbach Ro X Romar was a German long-range commercial flying-boat and the last aircraft designed and built by Rohrbach Metall Flugzeugbau GmbH.
The Tupolev ANT-16 was an experimental heavy bomber aircraft designed and tested in the Soviet Union in the early 1930s.
The Grigorovich TB-5 was an experimental heavy bomber designed and tested in the Soviet Union in the early 1930s. Designed as a competitor for the Tupolev TB-3, the TB-5 was intended to be powered by two FED 24-cylinder X engines of 746 kW (1,000 hp) each. When these were canceled, the underwing pods were revised to each house a pair of Bristol Jupiter engines in a push-pull configuration. Despite projected performance inferior to TB-3, it was hoped that TB-5 would gain an advantage by using less metal thanks to its mixed construction of fabric-covered metal frame.
The Sikorsky S-10 was a Russian military twin-float seaplane that served with the Russian Navy's Baltic Fleet from the summer of 1913 to 1915. After Igor Sikorsky built the successful Sikorsky S-6 for the Russian military, he tried to build another successful aircraft for them. The S-10 was a modified S-6B built by the Russo-Baltic Carriage Factory. Approximately sixteen production versions of the S-10 were built. It had a less powerful engine and generally weaker structure than the S-6. They had either an 80 hp Gnome Monosoupape or a 100 hp Argus Motoren engine. Some were deployed on the world's first operational seaplane carriers.
The Potez 75 was a low-cost, simple, ground-support, observation and launch aircraft for anti-tank missiles, designed and built in the early 1950s, for use in colonial conflicts. One hundred and fifteen were ordered in 1956, but cancelled in 1957.
The Zeppelin-Staaken E-4/20 was a revolutionary four-engine all-metal passenger monoplane designed in 1917 by Adolf Rohrbach and completed in 1919 at the Zeppelin-Staaken works outside Berlin, Germany. The E-4/20 was the first four-engine, all-metal stressed skin heavier-than-air airliner built.
The Akaflieg Berlin B13 is a two-seat motor-glider designed and built in Germany.
Akaflieg Darmstadt is one of approximately twenty aviation groups attached to German universities. Akaflieg is an abbreviation for Akademische Fliegergruppe, an academic group of students and faculty from a German University.
The Akaflieg Berlin B 9 was a twin-engined experimental aircraft, developed by Akaflieg Berlin and Flugtechnische Fachgruppe in the 1940s. It was designed to examine the benefits of having a pilot in a prone position. The aircraft was flown in 1943, but was eventually abandoned.
The Summit Steel Breeze is an American powered parachute, designed and produced by Summit Aerosports of Yale, Michigan. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.
The Evektor VUT100 Cobra is a Czech light aircraft under development by Evektor-Aerotechnik, of Kunovice. The aircraft is intended to be supplied as a complete ready-to-fly-aircraft.
The Ruhrtaler Ru.3 was a German advanced single-seat trainer designed to take pilots to combat standards. Initial flying tests showed promise but the owner of Ruhrtaler cancelled all aeronautical activity after his son was killed whilst demonstrating the Ru.3 to the Air Ministry.
The Akaflieg Berlin B1 Charlotte, was a glider built in Germany in the 1920s. It featured a high-wing, tailless sailplane configuration of all-wood construction, which had a pair of skids for landing.
The Akaflieg Berlin B2 Teufelchen was a glider built in Germany in the 1920s. It featured a high-wing, cantilever sailplane configuration of all-wood construction.
The Akaflieg Berlin B3 Charlotte II was a glider built in Germany in the 1920s. It featured a high-wing, tailless sailplane configuration of all-wood construction, which had a single skid for landing and applied brakes.
