Sukhoi T-3
The Sukhoi T-3 was a prototype Soviet fighter aircraft. Development Starting in the early 1950s, the development of the T-3 proceeded in parallel with the S-1 which would eventually become the Sukhoi Su-7. While the S-1 was a conventional swept wing aircraft (''S'' stood for ''strelovidniy'', стреловидный, swept wing), the T-3 had a delta wing with a leading edge sweep of 57° (''T'' stood for ''treugolniy'', треугольный, delta wing).Green, William. "The Great Book of Fighters". 2001. MBI Publishing. Aside from the wings, the two aircraft shared the basic design as well as the Lyulka AL-7 turbojet engine. Since the T-3 was intended to be an interceptor, it was fitted with the ''Almaz'' (Алмаз, Diamond) radar housed in the air intake. The prototype first flew on 26 May 1956. The T-3 was ordered into production at Factory No.153 but events overtook it when a revised specification was issued for the Interceptor fighter role. Three aircraft were comple ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta-wing Aircraft
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 (letter), delta (Δ). Although long studied, it did not find significant applications until the Jet Age, when it proved suitable for high-speed Subsonic aircraft, subsonic and supersonic flight. At the other end of the speed scale, the Rogallo wing, 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 ...

1950s Soviet Fighter Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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.

Kaliningrad K-8
The Kaliningrad K-8 (R-8) (NATO reporting name AA-3 'Anab') was a medium-range air-to-air missile developed by the Soviet Union for interceptor aircraft use.Gordon, Yefim. ''Soviet/Russian Aircraft Weapons''. Midland. 2004. The missile was developed by OKB-339/NII-339 (currently Phazotron, Phazotron NIIR). The infrared seeker was developed by TsKB-589 GKOT (currently TsKB Geofizika), who also developed the seeker for 9M31 missile of 9K31 Strela-1. History The K-8's development began in 1955, known as R-8 in service. Like most Soviet air-to-air missiles, it was made with a choice of semi-active radar homing or infrared homing, infrared seeker heads. The original missile was compatible with the Uragan-5B radar used on the Sukhoi Su-11 and several developmental aircraft from Mikoyan-Gurevich. It was upgraded to R-8M (better known as R-98) standard in 1961, giving the SARH weapon the capability for head-on intercepts. In 1963 it was further upgraded to the R-8M1, making it compatibl ...

Afterburning 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-powere ...

Lyulka AL-7F
The Lyulka AL-7 was a turbojet designed by Arkhip Mikhailovich Lyulka and produced by his Lyulka design bureau. The engine was produced between 1954 and 1970.Gunston 1989, p.100. Design and development The AL-7 had supersonic airflow through the first stage of the compressor. TR-7 prototype, developing 6,500 kgf (14,330 lbf, 63.7 kN) of thrust Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction to be applied to that sys ..., was tested in 1952, and the engine was initially intended for Ilyushin's Il-54 bomber. The afterburning AL-7F version was created in 1953. In April 1956, the Sukhoi S-1 prototype, equipped with the AL-7F, exceeded Mach 2 at 18,000 m (70,900 ft), which led to the production of the Su-7 'Fitter' and Su-9 'Fishpot', equipped with this engine.Green, William and Gordon Swanborough ...
