The Heinkel He 111 is a German airliner and medium bomber designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934. Through development, it was described as a "wolf in sheep's clothing". Due to restrictions placed on Germany after the First World War prohibiting bombers, it was presented solely as a civil airliner, although from conception the design was intended to provide the nascent Luftwaffe with a heavy bomber.
The Heinkel He 177 Greif (Griffin) was a long-range heavy bomber flown by the Luftwaffe during World War II. The introduction of the He 177 to combat operations was significantly delayed by problems both with the development of its engines and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the Luftwaffe during the conflict. The He 177 had a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the European theatre.
The Gotha Go 242 was a transport glider used by the Luftwaffe during World War II. It was an upgrade over the DFS 230 in both cargo/troop capacity and flight characteristics. It saw limited combat action. There were multiple glider variants, and it became the basis for a transport aircraft, the: Gotha Go 244.
The Heinkel HE 18 was a sports aircraft built in Germany in the mid 1920s. It was a two-seat conventional low-wing monoplane. A development of the HE 3, it had a narrower fuselage than the HE3, having tandem seating instead of side-by-side. Also, its wings were braced by a pair of struts on each side, arranged in a V-shape with a single attachment point on each side of the upper fuselage, where the HE 3 had cantilever wings. The wings could be folded flat along the sides of the fuselage for transport or storage, and a choice of wheeled or float undercarriage was available. A roll-bar was available that could be fitted in order to protect the occupants in case of a roll-over on the ground.
The Heinkel HE 5, produced in Sweden as the Svenska Aero S 5 and nicknamed the "Hansa", was a reconnaissance floatplane built during the 1920s. It was a further development of the HE 1, sharing its same basic configuration as a low-wing, strut-braced monoplane. The HE designation also refers to the monoplane construction, standing for Heinkel Eindecker.
The Heinkel HD 17 was a military reconnaissance aircraft produced in Germany in the late 1920s.
The Heinkel HD 21 was a trainer built in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-type interplane struts. The main units of the fixed, tailskid undercarriage were linked by a cross-axle, and the aircraft had three open cockpits in tandem, although one of these was typically faired over. The HD 29 of 1925 was essentially similar, but was purely a two-seater.
The Heinkel HD 22 was a trainer designed in Germany during the 1920s. It was a conventional single-bay biplane with staggered wings braced with N-type interplane struts. The pilot and instructor sat in tandem, open cockpits, and the main units of the fixed, tailskid undercarriage were linked by a cross-axle.
The Heinkel HD 28 was a reconnaissance seaplane developed in Germany in the 1920s for export to Japan. It was a conventional single-bay biplane with equal-span, unstaggered wings and three cockpits in tandem. The fuselage was braced to both the upper and lower wings with a number of struts on its sides, in addition to the normal cabane struts. The rudder extended below the line of the lower fuselage, and there was a large ventral fin fitted. The rearmost cockpit incorporated a ring mount for a gunner.
The Heinkel HD 24 was a training seaplane developed in Germany in the late 1920s. It was a conventional single-bay biplane with equal-span, staggered wings. The fuselage was braced to both the upper and lower wings with a number of struts on its sides, in addition to the normal cabane struts. The pilot and instructor sat in tandem, open cockpits, and the undercarriage consisted of twin pontoons, although this could be readily exchanged for wheels or skis.
The Heinkel HD 35 was a trainer developed in Germany in the 1920s. It was a conventional single-bay biplane with staggered wings of equal span. The design was based on that of the HD 21, and like that aircraft, it had three open cockpits in tandem, although the most forward of these was usually faired over when not in use.
The Heinkel HD 39 was a special-purpose cargo aircraft developed in Germany in the 1920s to distribute the Berlin newspaper B.Z.. It was a conventional single-bay biplane with staggered wings of equal span, and a fuselage that nearly filled the interplane gap. The pilot sat in an open cockpit, and the undercarriage was of fixed, tailskid type with divided main units. The sole example of the type was built after Ernst Heinkel found out, by chance, that B.Z. required such an aircraft and had ordered two machines from Albatros. Heinkel convinced publisher Ullstein-Verlag to purchase a third aircraft from his firm.
The Heinkel HD 55 was a biplane flying boat produced in Germany in the early 1930s for use as a reconnaissance aircraft aboard Soviet warships. The design was based on the HD 15 mail plane of 1927 and was a conventional design for its time, with equal span, unstaggered wings, and an engine mounted tractor-wise on struts above the pilot's open cockpit. A second open cockpit was added on the rear fuselage to provide a position for a tail gunner.
The Aichi E3A was a reconnaissance seaplane developed in Germany as the Heinkel HD 56 to operate from warships of the Imperial Japanese Navy, which designated it the Type 90-1 Reconnaissance Seaplane. It was a conventional single-bay biplane with staggered wings braced by N-type interplane struts. The pilot and gunner sat in tandem, open cockpits.
The Heinkel Doppeldecker 43 was a prototype German fighter aircraft of the 1930s. A single-engined, single-seat biplane, the HD 43 was designed to meet a secret German Reichswehr requirement for a single-seat fighter. It had two-bay wooden wings with a steel-tube fuselage, and was powered by a 750 hp (600 kW) BMW VI engine. The single prototype flew in 1931.
The Junkers EF 126 was an experimental fighter proposed by the German Miniaturjägerprogramm of 1944–1945, for a cheap and simple fighter powered by a pulsejet engine. No examples were built during the war, but the Soviet Union completed both unpowered and powered prototypes.
The Blohm & Voss P 212 was a proposed jet fighter designed by Blohm & Voss for the Emergency Fighter Program Luftwaffe design competition during the Second World War.
The Messerschmitt P.1110 was a design for a single-seat, high-altitude interceptor, prepared for the German Luftwaffe by the Messerschmitt aircraft manufacturing company, under the Emergency Fighter Program during the last months of World War II.
The Heinkel HD 20 was a twin engine, three seat German biplane built in 1926 for civil survey work.
The Messerschmitt P.1107 was a jet-powered bomber project developed in the final years of the Second World War.
