The Focke-Wulf Ta 183 Huckebein was a design for a jet-powered fighter aircraft intended as the successor to the Messerschmitt Me 262 and other day fighters in Luftwaffe service during World War II. It had been developed only to the extent of wind tunnel models when the war ended, but the basic design was further developed postwar in Argentina as the FMA IAe 33 Pulqui II. The name Huckebein is a reference to a trouble-making raven (Hans Huckebein der Unglücksrabe) from an illustrated story in 1867 by Wilhelm Busch.[1]
In early 1944, the Reich Air Ministry (RLM, for Reichsluftfahrtministerium) became aware of Allied jet developments, and were particularly concerned that they might have to face the Gloster Meteor over the continent. In response, they instituted the Emergency Fighter Program which took effect on July 3, 1944, ending production of most bomber and multi-role aircraft in favour of fighters, especially jet fighters. Additionally, they accelerated the development of experimental designs that would guarantee a performance edge over the Allied designs, designs that would replace the first German jet fighters, the Messerschmitt Me 262Schwalbe and Heinkel He 162Spatz.
A menacing "Hans Huckebein", the namesake raven for the Ta 183
The result was a series of advanced designs, some using swept wings for improved transonic performance, others instead using the tailless design to lower drag to the same end. Since German aircraft engineers were aware that tailless designs might encounter serious stability problems at transonic speeds, much as the prototype Me 163B V18 did on July 6, 1944, in hitting a record 1,130km/h (702mph) top speed and nearly destroying its entire rudder surface in the process,[2][3] a variety of stabilization methods such as airbrakes on the wings were considered for such aircraft or simply adding conventional tail surfaces. Kurt Tank's design team led by Hans Multhopp designed in 1945 a fighter known as "Huckebein" (from Wilhelm Busch's "Hans Huckebein, the unlucky raven", a cartoon raven that traditionally makes trouble for others), also known as Project V (Project VI in some references) or Design II at Focke-Wulf. The raven character itself was re-used for the modern Bundeswehr's Lufttransportgeschwader 62 as the inspiration for their unit's insignia.

Development of the Ta 183 started as early as 1942 as Project VI, when the engineer Hans Multhopp assembled a team to design a new fighter, based on his understanding that previous Focke-Wulf design studies for jet fighters had no chance of reaching fruition because none had the potential for transonic speeds. This aircraft, bearing the RLM airframe number 8-183, was intended to use, as with a growing number of other advanced German late-war jet aircraft proposals, the advanced Heinkel HeS 011turbojet; although the first prototypes were to be powered by the Junkers Jumo 004B. Early studies also included an optional 1,000kgf (10kN) thrust rocket engine for takeoff and combat boost, much as the special "003R" version of the BMW 003 jet engine was meant to use, with fuel and oxidiser for up to 200 seconds of burn time stored in drop tanks under the wings.
The wings were swept back at 40° and were mounted in the mid-fuselage position. The wings appear to be mounted very far forward compared with most designs, a side-effect of attempting to keep the centre of pressure (CoP) of the wing as a whole as close to the middle of the fuselage as possible. Reflecting the dilemma of a shortage of strategic materials, the first option of using aluminum in the construction of the main spar consisting of two tapered I-beams attached together on the top and bottom with shear webs of thin steel sheeting, led to a reappraisal. Multhopp chose to use wood instead of metal throughout the wing structure, with wood structure ribs attached to the front and back of the I-beams to give the wing its overall shape, and then covered with plywood. The box-like structure contained six fuel cells, giving the aircraft a total fuel load of 1,565L (413US gal).[4]
The original design used a T-tail, with a notably long vertical stabilizer and a seemingly undersized horizontal stabilizer. The vertical stabilizer was swept back at 60°, and the horizontal stabilizer was swept back and slightly dihedralled. The horizontal stabilizer also featured two large trim tabs, the main pitching force actually being provided by what would have appeared to be "ailerons" on most other turbojet-powered fighter airframes of the period. The Ta 183 wing's outermost trailing-edge control surfaces on its wing panels, were well behind the center of gravity, placing their trailing edges' tips virtually even, horizontally, with the intended HeS 011 jet engine's exhaust orifice, and thus could provide both pitch and roll control through functioning as elevon control surfaces, as those on the wing panels of Messerschmitt's Me 163 tailplane-less Komet rocket fighter already did. Many problems beset the project, including the chance of a Dutch roll. Work therefore concentrated on the much less problematic Focke-Wulf Project VII. However, when the RLM eventually rejected that design, Huckebein was again brought to the fore.
The Ta 183 had a short fuselage with the air intake passing under the cockpit and proceeding to the rear where the single engine was located. The pilot sat in a pressurized cockpit with a bubble canopy which provided excellent vision. The primary armament of the aircraft consisted of four 30mm (1.18in) MK 108 cannons arranged around the air intake.
It was also possible to carry a bomb load of 500kg (1,100lb), consisting of one SD or more SC 500 half-tonne bombs, one Bombentorpedo BT 200 bomb, five SD-series fragmentation bombs, SC-series general-purpose bombs, or a Rb 20/30 reconnaissance camera. The weapons load would be carried in the equipment space in the bottom of the fuselage and thus partially protrude about halfway from the fuselage, possibly allowing for other armament packages such as the Ruhrstahl X-4 wire-guided missile.
Multhopp's team also seriously explored a second version of the basic design, known as Design III, a modified Design II (it is unknown what Design I referred to). The first of these had only minor modifications, with slightly differently shaped wingtips and repositioning of the undercarriage. The second version had a reduced sweepback to 32°, allowing the wing and cockpit to be moved rearward. The tail was also redesigned, using a short horizontal boom to mount the control surfaces just above the line of the rear fuselage. This version looks considerably more "conventional" to the modern eye, although somewhat stubby due to the short overall length of the HeS 011.
The second of these two schemes was entered in the official competition ordered by the Oberkommando der Luftwaffe at the end of 1944. On 28 February 1945, the Luftwaffe High Command examined the various Emergency Fighter proposals and selected the Junkers EF 128 to be developed and produced; the Focke-Wulf team gained second place. However, in the last few weeks of the war, it was decided that the Huckebein was really the best design and, at a meeting in Bad Eilsen, Tank was told to arrange mockups and to plan for full production. It had a planned speed of about 1,000km/h (620mph) at 7,000m (22,970ft) and it was estimated that 300 aircraft per month would be delivered when production got into its stride, each aircraft being produced in 2,500 man hours.
A total of 16 prototypes were to be built, allowing the tail unit to be interchanged between the Design II and III variations. Of the Versuchs (experimental test series) aircraft, the Ta 183 V1-V3 were to be powered by the Jumo 004B turbojet with somewhat lengthened rear fuselages near the engine's exhaust nozzle to accommodate them, pending delivery of the HeS 011 jet engine. The Ta 183 V4-V14 were intended to be A-0 series pre-production aircraft and V15-V16 were to be static test aircraft. The first flight of the aircraft was projected for May 1945, but no finished Ta 183 Versuchs-series prototypes had been completed by 8 April 1945, when British troops captured the Focke-Wulf facilities.
Influence
Pulqui II on takeoff
After the end of the war, Kurt Tank, in exile in Argentina, resurrected the Ta 183 project, resulting in the IAe Pulqui II.[5] This version was modified to place the wings at a shoulder-mounted position, in order to avoid a heavy fuselage spar pass-through structure going around the engine, however this resulted in deep stall problems at high angles of attack. This could be resolved, and a version correcting these problems was planned. However, the financial crash of 1953[clarification needed] and the fall of Juan Peron temporarily suspended work on the project. By 1955, the project had been abandoned due to the availability of surplus ex-Korean WarF-86 Sabres at a fraction of the cost.[citation needed]
The MiG-15, which bears a resemblance to both the Ta 183 and Me 263.
Historians including David Myrha[6] have claimed the Soviet Mikoyan-Gurevich MiG-15 was at least inspired by the Ta 183, because the Soviets captured plans from the Germans at the end of World War II. The MiG-15 does bear a resemblance in layout, sharing the high tailplane and nose-mounted intake, although the aircraft are different in structure, details, and proportions. The MiG-15's design shared features, and some appearance commonalities with the MiG design bureau's own 1945-46 attempt at a Soviet-built rocket interceptor similar to the Messerschmitt Me 263 rocket fighter, and also common to many contemporary jet fighters — and were derived from aerodynamic and structural considerations (for example, the American Republic F-84F, the Swedish SAAB 29, and the French Dassault Ouragan and Mystère). A detailed design history of the MiG-15 was published by Russian aviation historian Yefim Gordon[7] refuting any connection between the Ta 183 and the MiG-15. According to the designers, the MiG-15 was an indigenous design, their choice of swept wings (as swept-back wings of any sort on a Soviet-designed aircraft were first flown on the MiG-8Utka canard light aircraft of 1945) being due to their desire to move ahead of most Western designs which were not intended for the 960km/h+ (600mph+) speed range.
Like the MiG-9 and MiG-15, the Saab 29 is subject to claims of having been indirectly influenced by the Ta 183. SAAB engineers received German research studies in swept wings in the immediate post-war period via contacts in Switzerland, and incorporated it into the Tunnan design, which was still limited to paper studies at the time.[8]
Focke-Wulf Flugzeugbau AG was a German manufacturer of civil and military aircraft before and during World War II. Many of the company's successful fighter aircraft designs were slight modifications of the Focke-Wulf Fw 190. It is one of the predecessor companies of today's Airbus.
A swept wing is a wing angled either backward or occasionally forward from its root rather than perpendicular to the fuselage.
The Saab 29 Tunnan, colloquially also Flygande Tunnan, is an early jet-powered fighter aircraft designed and produced by the Swedish aircraft manufacturer Saab. It was the second turbojet-powered combat aircraft to be developed in Sweden, the first being the Saab 21R, and it was the first Western European fighter to be produced with a swept wing after the Second World War, only being preceded in Western Europe as a whole by the Messerschmitt Me 262 built during the conflict.
The Emergency Fighter Program was the program that resulted from a decision taken on July 3, 1944 by the Luftwaffe regarding the German aircraft manufacturing companies during the last year of the Third Reich.
Wunderwaffe is a German word meaning "wonder-weapon" and was a term assigned during World War II by Nazi Germany's propaganda ministry to some revolutionary "superweapons". Most of these weapons however remained prototypes, which either never reached the combat theater, or if they did, were too late or in too insignificant numbers to have a military effect. The V-weapons, which were developed earlier and saw considerable deployment, especially against London and Antwerp, trace back to the same pool of highly inventive armament concepts. In the German language, the term Wunderwaffe now generally refers to a universal solution which solves all problems related to a particular issue, mostly used ironically for its illusionary nature.
The FMA IAe 33 Pulqui II was a jet fighter aircraft designed by Kurt Tank in the late 1940s in Argentina, under the Perón government, and built by the Fábrica Militar de Aviones (FMA). Embodying many of the design elements of the wartime Focke-Wulf Ta 183, an unrealized fighter project, the FMA envisioned the IAe 33 Pulqui II as a successor to the postwar Gloster Meteor F4 in service with the Fuerza Aérea Argentina. The Pulqui II's development was comparatively problematic and lengthy, with two of the four prototypes being lost in fatal crashes. Despite one of the prototypes being successfully tested in combat during the 1955 Revolución Libertadora, the political, economic and technical challenges faced by the project meant that the IAe 33 was unable to reach its full potential, and the Argentine government ultimately chose to purchase F-86 Sabres from the United States in lieu of continuing development of the indigenous fighter to production status.
The Messerschmitt P.1101 was a single-seat, single-jet fighter project of World War II, developed as part of the 15 July 1944 Emergency Fighter Program which sought a second generation of jet fighters for the Third Reich. A prominent feature of the P.1101 prototype was that the sweep angle of the wings could be changed before flight, a feature further developed in later variable-sweep aircraft such as the Bell X-5 and Grumman XF10F Jaguar.
Hans Multhopp was a German aeronautical engineer/designer. Receiving a degree from the University of Göttingen, Multhopp worked with the famous designer Kurt Tank at the Focke-Wulf Flugzeugbau AG during World War II, and was the leader of the team responsible for the design of the Focke-Wulf Ta 183 lightweight jet fighter, which was the winner of the 1945 Emergency Fighter Competition. Emigrating to the United Kingdom after the war, he assisted in the advancement of British aeronautic science before moving to the United States, where his work for Martin Marietta on lifting bodies provided aerodynamic experience that proved instrumental in the development of the Space Shuttle.
The Focke-Wulf Project I was a design study for a jet fighter, to be built in Germany during World War II. In 1942, the Reichsluftministerium (RLM) asked Professor Kurt Tank of the Focke-Wulf factory to investigate the possibility of a single-engine jet fighter. He was given the development plans of the BMW 003, Jumo 004 and Heinkel HeS 011 engines. Late in 1942 the Project Office, led by Ludwig Mittelhuber, began to work on a series of fighter projects, to be powered by one of these new turbojet units.
The Heinkel He P.1079 was a projected German V-tail all weather jet fighter designed by Heinkel Flugzeugwerke in the closing stages of World War II. The aircraft was only a design; it was not produced.
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 Junkers EF 128 was a project for a single-engine jet fighter, developed for the Emergency Fighter Program Luftwaffe design competition during the Second World War.
The Heinkel P.1078 was a single seat interceptor developed for the Luftwaffe by Heinkel aircraft manufacturing company under the Emergency Fighter Program during the last years of the Third Reich.
The Focke-Wulf Super Lorin was a proposed German jet interceptor project. Designed towards the end of World War II by engineer Heinz von Halen, the project remained only a factory design exercise, and never received an RLM airframe number before the surrender of Nazi Germany.
The Focke-Wulf 1000x1000x1000, also known as Focke-Wulf Fw 239, was a twinjet bomber project for the Luftwaffe, designed by the Focke-Wulf aircraft manufacturing company during the last years of the Third Reich.
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 Focke-Wulf Volksjäger, was a German emergency fighter project for the Luftwaffe. It was designed by Focke-Wulf towards the end of World War II as part of the defense effort against the devastating Allied bombing raids.
The Blohm & Voss P215 was an advanced jet night fighter project by Blohm & Voss during the Second World War. With a crew of three and twin jet engines, it featured a tailless swept-wing layout and heavy armament. An order for three prototypes was received just weeks before the war ended.
The Messerschmitt P.1107 was a jet-powered bomber project developed in the final years of the Second World War.
