Messerschmitt P.1111
The Messerschmitt P.1111 was a jet fighter/interceptor project, designed by Messerschmitt for the ''Luftwaffe'' near the end of World War II. History The innovative design of the Me P.1111 was completed in January 1945, and was intended as an improvement to the Messerschmitt P.1110 ''Ente''.Heinz J. Nowarra: ''Die Deutsche Luftrüstung 1933–1945'', Band 3, Bernard & Graefe Verlag Koblenz 1993, , page 253 The Messerschmitt P.1111 was an 8.92 m long tailless airplane with nearly delta-shaped wings, swept back at a 45 degree angle, and a wingspan of 9.12 m. It was equipped with a pressurized cockpit for a single pilot. The planned powerplant was a Heinkel HeS 011 turbojet engine, and armament was to be four 30 mm MK 108 cannon. During a design review comparison conference in Oberammergau on February 27 and 28, 1945 the P. 1111 fared outstanding in the area of performance in high-speed flight capability, take-off, climb and landing performance. The experts held the opini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heinkel HeS 011
The Heinkel HeS 011 or Heinkel-Hirth 109-011 ''(HeS - Heinkel Strahltriebwerke)'' was an advanced World War II jet engine built by Heinkel-Hirth. It featured a unique compressor arrangement, starting with a low-compression impeller in the intake, followed by a "diagonal" stage similar to a centrifugal compressor, and then a three-stage axial compressor. Many of the German jet-powered aircraft designs at the end of the war were designed to use the HeS 011, but the HeS 011 engine was not ready for production before the war ended in Europe and only small numbers of prototypes were produced. Design and development Starting in 1936, Junkers started a jet engine development project under the direction of Wagner and Müller, who worked on axial compressor designs. By 1940 they had progressed to the point of having a semi-working prototype, which could not run under its own power and required an external supply of compressed air. Meanwhile, Hans Mauch, in charge of engine development a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1940s German Fighter Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Messerschmitt Aircraft
Messerschmitt AG () was a German share-ownership limited, aircraft manufacturing corporation named after its chief designer Willy Messerschmitt from mid-July 1938 onwards, and known primarily for its World War II fighter aircraft, in particular the Bf 109 and Me 262. The company survived in the post-war era, undergoing a number of mergers and changing its name from Messerschmitt to Messerschmitt-Bölkow-Blohm before being bought by Deutsche Aerospace (DASA, now part of Airbus) in 1989. History Background In February 1916, the south German engineering company MAN AG and several banks purchased the unprofitable aircraft builder Otto-Flugzeugwerke, starting a new company, ''Bayerische Flugzeugwerke AG'' (abbreviated ''B.F.W.''). The articles of association were drawn up on 19 and 20 February, and completed on 2 March 1916. Details of the company were recorded in the Commercial Register with an equity capital of RM 1,000,000 on 7 March 1916. 36% of the capital was provide ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MK 108 Cannon
The MK 108 (German: ''Maschinenkanone''—"machine cannon") was a 30 mm caliber autocannon manufactured in Germany during World War II by Rheinmetall‑ Borsig for use in aircraft. The cannon saw widespread use as an anti-bomber weapon during the second half of the war, first seen in 1943 in the Bf 110G-2 bomber destroyers and Bf 109G-6/U4. Four MK 108's formed the main armament of the Me 262 the next year. It could be found on some versions or optional mountings on practically every other German fighter of the era. Development The weapon was developed as a private venture by the company in 1940 and was submitted to the '' Reichsluftfahrtministerium'' (RLM—Reich Aviation Ministry) in response to a 1942 requirement for a heavy aircraft weapon for use against the Allied heavy bombers appearing over German-controlled regions by then. Testing verified that the autocannon was well suited to this role, requiring on average just 4 hits with its 85g RDX-load (in a 330g shell) a ...

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally Forward-swept wing, forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward-swept wing, forward sweep, Variable-sweep wing, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fighter Aircraft
Fighter aircraft are fixed-wing aircraft, fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. ...

Delta Wing
A delta wing is a wing shaped in the form of a triangle. It is named for its similarity in shape to the Greek uppercase letter delta (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed subsonic and supersonic flight. At the other end of the speed scale, the Rogallo flexible wing proved a practical design for the hang glider and other ultralight aircraft. The delta wing form has unique aerodynamic characteristics and structural advantages. Many design variations have evolved over the years, with and without additional stabilising surfaces. General characteristics Structure The long root chord of the delta wing and minimal structure outboard make it structurally efficient. It can be built stronger, stiffer and at the same time lighter than a swept wing of equivalent lifting capability. Because of this it is easy and relatively inexpensive to build – a substantial factor in the success of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
