The Argus As 10 was a German-designed and built, air-cooled 90° cylinder bank-angle inverted V8 "low power" aircraft engine, used mainly in training aircraft such as the Arado Ar 66 and Focke-Wulf Fw 56 Stösser and other small short-range reconnaissance and communications aircraft like the Fieseler Fi 156 Storch during, and shortly after World War II. It was first built in 1928.
The Argus As 8 was a four-cylinder, air-cooled, inverted inline aircraft engine produced in Germany by Argus Motoren in the 1930s.
The Hirth HM 508 was an air-cooled, eight-cylinder, 60° cylinder bank angle inverted-V aircraft engine built in Germany in the 1930s. It had a bore and stroke of 105 mm × 115 mm and developed 210 kW (280 hp) at 3,000 rpm.
The Hirth HM 504 is a four-cylinder air-cooled inverted inline engine. The HM 504 was a popular engine for light aircraft of the 1930s-1940s, and it was used to power a number of Germany's trainer aircraft of World War II. The engine featured a cast magnesium alloy crankcase made of Elektron The Hitachi Hatsukaze Model 11 was a Japanese licensed version.
The Argus As 410 was a German air-cooled inverted V-12 aircraft engine that was first produced by Argus Motoren in 1938.
The Hirth HM 506 was a six-cylinder air-cooled inverted inline engine that was developed from the earlier four-cylinder HM 504. The HM 506 was a popular engine for light aircraft of the 1930s to 1940s and powered the Bücker Bü 133A model trainer. The engine featured a cast magnesium alloy crankcase.
The Hirth HM 60 was a four-cylinder inverted air-cooled inline aircraft engine designed in 1923 and first sold in 1924. The engine was of very high quality, and its sales success contributed to Hirth's rapid pre-war expansion. It was a popular engine for light aircraft delivering 80 hp (60 kW) at 2,300 rpm. Later Hirth engines built upon the HM 60's success and provided greater power with many of the same design features.
The BMW X is a small five-cylinder radial engine for sport and training aircraft. Although this engine proved successful at several large-scale events in 1930, including that year's round-Europe flight, only a few were built.
The Akaflieg Stuttgart F-1 Fledermaus (Bat) was a glider designed and built in Germany from 1932.
The Akaflieg Stuttgart fs16, nicknamed Wippsterz was a glider aircraft that was designed and built in Germany from 1936. Only one example of the design was constructed.
The Akaflieg Stuttgart fs17 was a glider aircraft that was designed and built in Germany from 1936. It notably featured a prone seating position for its pilot.
The Akaflieg Stuttgart fs18a was a glider designed and built in Germany from 1938. It was characterized by a gull wing and was the first glider to have a retractable undercarriage. Only one example of the design was constructed.
The Hirth HM 512 was a 12-cylinder development of the earlier, 6-cylinder HM 506, produced in the late 1930s. Both were supercharged, inverted V, air-cooled engines.
The DFS Seeadler was a German flying boat sailplane designed by Hans Jacobs of the Deutsche Forschungsanstalt für Segelflug (DFS). It was version of the 1935 DFS Rhönadler, with a new fuselage and strongly gulled wings to keep them clear from spray. The aircraft was first flown in the summer of 1935, test piloted by Hanna Reitsch, and towed by a Dornier Do 12.
The Zündapp 9–092 or Z 92 was a German four-cylinder, air-cooled, inline aero engine made by Zündapp and used in light aircraft of the late-1930s.
The Schneider Grunau 7 Moazagotl was a high-performance sailplane designed in Germany in 1933 specifically for fast, long distance flying using strong thermals. In 1937 it came second in the first World Gliding Championships, having previously made a flight of 300 km (186 mi).
The Akaflieg Berlin B5 was a glider built in Germany in the late 1930s. It featured a high-wing, cantilever sailplane configuration of all-wood construction, with cantilevered gull-wings, retractable landing-gear, all-moving-tail, dive air-brakes.
The Hirth HM 501 was a 6-cylinder air-cooled inverted in-line engine that was developed by Hirth Motoren GmbH in the late 1930s, from the 4-cylinder HM 500 and used principally on the submarine-born Arado Ar 231.
The Hirth HM 515 was a four-cylinder air-cooled inverted inline engine, intended to power light aircraft of the 1940s. Due to World War II, demand for the light aircraft to be powered by the HM 515 dried up and only the Siebel Si 202C Hummel was powered by development engines before further work was abandoned.
The Kroeber M4 Köller was a 2-stroke air-cooled horizontally-opposed piston engine designed and built by Dr. Kroeber & Sohn G.m.b.H. in Germany in the late 1930s. The M4 proved relatively popular, for powering the ultra-light aircraft and motor-gliders in vogue during the 1920s and 1930s.
