FFA P-16
The FFA P-16 is a Swiss prototype ground attack jet fighter designed and produced by aircraft manufacturer Flug- und Fahrzeugwerke Altenrhein (FFA). It was Switzerland's second attempt to develop a domestically designed and manufactured jet fighter, following the EFW N-20. Work on what would become the P-16 commenced during the late 1940s. From the onset, the company intended for the indigenously developed fighter to replace several piston-engined aircraft that were then in service with the Swiss Air Force. During 1952, a pair of prototypes were ordered from FFA. On 25 April 1955, the first prototype performed its maiden flight. On 15 August 1956, the second prototype exceeded the sound barrier for the first time. The flight test programme demonstrated the P-16 to be capable of achieving favourable performance; accordingly, a production contract for 100 aircraft was issued by the Swiss Government. In the aftermath of a pre-production aircraft's crash, the Swiss production orde ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flug- Und Fahrzeugwerke Altenrhein
Flug- und Fahrzeugwerke Altenrhein AG (FFA) () was a Swiss aircraft and railroad car manufacturing company based at Altenrhein (SG). It was originally part of Dornier Flugzeugwerke, but was split off in 1948. History In the years following World War II, FFA manufactured fighter aircraft for the Swiss Air Force, based on Morane-Saulnier designs as the D-3803. These were eventually replaced in service by surplus P-51 Mustangs. In the 1950s, FFA developed a jet fighter, the P-16. The P-16 project, while promising, was cancelled after two crashes, and Hawker Hunters were bought instead. Also the project for a Bizjet SAAC-23 was cancelled. In the 1960s the company built the Diamant series of sailplanes.Rogers, Bennett: ''1974 Sailplane Directory, Soaring Magazine'', page 58. Soaring Society of America, August 1974. USPS 499-920 The firm licence-built many aircraft for Swiss use, including the de Havilland Vampire, de Havilland Venom, Dassault Mirage III, and F-5 Tiger II. In 1987 ...

Fighter-bomber
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles. Although still used, the term fighter-bomber has less significance since the introduction of rockets and guided missiles into aerial warfare. Modern aircraft with similar duties are now typically called multirole combat aircraft or strike fighters. Development Prior to World War II, general limitations in available Aircraft engine, engine and Aerospace engineering, aeronautical technology required that each proposed military aircraft have its design tailored to a specific prescribed role. Reciprocating engine, Engine power grew dramatically during the early period of the war, roughly doubling between 1939 and 1943. The Bristol Blenheim, a typical ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Alloy
An alloy is a mixture of chemical elements of which in most cases at least one is a metal, metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and Copper(II) sulfate, copper. A typical example of an alloy is SAE 304 stainless steel, 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is ...

Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its Stabilizer (aeronautics), stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in Motorsport, motor sports, with for example in Le Mans Prototype, Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may s ...

Tailplane
A tailplane, also known as a horizontal stabilizer, is a small lift (force), lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canard (aeronautics), Canards, tailless aircraft, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the center of pressure (fluid mechanics), centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable Elevator (aeronautics), ...

Close Air Support
Close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with special forces if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction, battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not ...

Learjet 23
The Learjet 23 (originally Lear Jet 23) is an American six-to-eight-seat (two crew and four to six passengers) twinjet, high-speed business jet manufactured by Learjet. Introduced in 1964, it was Learjet's first model and created a new market for fast and efficient small business aircraft. Production ended in 1966 after 101 aircraft had been delivered. Development Recognizing the potential of the FFA P-16 fighter jet, a Swiss single-engine ground-attack plane designed by Flug- und Fahrzeugwerke Altenrhein (FFA), William (Bill) Powell Lear, Sr. established Swiss American Aviation Corporation (SAAC) to produce a two-engined passenger version: the SAAC-23 Execujet. The company moved to Wichita, Kansas and was renamed Lear Jet Corporation. Production began on the first Model 23 Lear Jet on 7 February 1962. The first flight took place on 7 October 1963 with test pilots Hank Beaird and Bob Hagen. On 4 June 1964, the prototype crashed soon after takeoff, when the pilot inadverten ...

Inventor
An invention is a unique or novel device, method, composition, idea, or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. The ideation process may be augmented by the applications of algorithms and methods from the domain collectively known as artificial intelligence . Some inventions can be patented. The system of patents wa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Armstrong Siddeley Sapphire
The Armstrong Siddeley Sapphire is a British turbojet engine that was produced by Armstrong Siddeley in the 1950s. It was the ultimate development of work that had started as the Metrovick F.2 in 1940, evolving into an advanced axial flow design with an annular combustion chamber that developed over . It powered early versions of the Hawker Hunter and Handley Page Victor, and every Gloster Javelin. Production was also started under licence in the United States by Wright Aeronautical as the J65, powering a number of US designs. The Sapphire's primary competitor was the Rolls-Royce Avon. Design and development Design evolution of the Sapphire started at Metropolitan-Vickers (Metrovick) in 1943 as an offshoot of the F.2 project. With the F.2 reaching flight quality at about , Metrovick turned to producing larger designs, both an enlarged F.2 known as the ''Beryl'', as well as the much larger F.9 ''Sapphire''. (The names were chosen after a decision to use gemstones for future ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

De Havilland Venom
The de Havilland DH 112 Venom is a British post-war single-engined jet aircraft developed and manufactured by the de Havilland, de Havilland Aircraft Company. Much of its design was derived from the de Havilland Vampire, the firm's first jet-powered combat aircraft; it was initially referred to as the ''Vampire FB 8'' prior to the adoption of the Venom name. The Venom was developed during the late 1940s to fulfil Air Ministry List of Air Ministry specifications#1940.E2.80.931949, Specification F.15/49, under which the aircraft was intended to be operated as an interim solution, lying between the first generation of British jet fighters – straight-wing aircraft powered by centrifugal compressor, centrifugal flow engines such as the Gloster Meteor and the Vampire – and later swept wing, axial compressor, axial flow-engined combat aircraft, such as the Hawker Hunter and de Havilland Sea Vixen. In comparison with the Vampire, it had a thinner wing and a more powerful de Havilla ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
