Shenyang J-XD
The Shenyang J-50, J-XD, or J-XDS, is a temporary designation given by military analysts and defense media to a twinjet tailless lambda wing aircraft under development by the Shenyang Aircraft Corporation (SAC). The aircraft was observed in flight testing in Shenyang, Liaoning, China in December 2024, which was tentatively named Shenyang J-XD or Shenyang J-50 by analysts, given the limited available information. History In 2018, Shenyang Aircraft Corporation (SAC) reportedly developed prototypes for the next-generation aircraft. Intelligence and rumors indicated the Chinese designs would use tailless flying wing or flying arrowhead configuration that can provide greater broadband stealth characteristics compared to the previous generation of fighters, new propulsion technologies, improved sensors allowing the aircraft to operate alongside unmanned teaming aircraft or unmanned combat aerial vehicles (UCAVs), etc. In September 2022, United States Air Force (USAF) General Mark D. K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cockpit
A cockpit or flight deck is the area, on the front part of an aircraft, spacecraft, or submersible, from which a pilot controls the vehicle. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy ...

Bomb Bay
The bomb bay or weapons bay on some military aircraft is a compartment to carry bombs, usually in the aircraft's fuselage, with "bomb bay doors" which open at the bottom. The bomb bay doors are opened and the bombs are dropped when over the target or at a specified launching point. History and function Bomb bays were born of necessity. Early military aircraft suffered severe aerodynamic drag (which would further slow down the already lumbering bomb-laden aircraft) with bombs hanging from the wings or below the fuselage, so military aviation designers moved the bombs inside the aircraft. Before the introduction of stealth technology bomb bays were mostly used by dedicated bomber aircraft; in fighters and attack airplanes bombs and rockets were hung from the wings or fuselage on hardpoint#Pylon, pylons. Notable exceptions are the F-101, F-102 and F-106 interceptor aircraft, all of which had bays used to store missiles, or other weapons stores. Today many designers have moved ...

Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', that is arranged in a tricycle fashion. The tricycle arrangement has one or more nose wheels in a single front undercarriage and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is now the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172.

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.

Diverterless Supersonic Inlet
A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet cowl, which work together to divert boundary layer airflow away from the aircraft's engine. This eliminates the need for a splitter plate, while compressing the air to slow it down from supersonic to subsonic speeds. The DSI can be used to replace conventional methods of controlling supersonic and boundary-layer airflow. DSIs can be used to replace the intake ramp and inlet cone, which are more complex, heavy and expensive. Technical background The fundamental design of a gas turbine engine is such that the air flow-rate entering its compressor is regulated by the amount of fuel burned in its combustor. For supersonic flight the air entering the inlet also has to be regulated to a similar amount by the design of the entrance of the inlet duct. The optimum design of the duct wil ...

Bubble Canopy
A bubble canopy is an aircraft canopy constructed without bracing, for the purpose of providing a wider unobstructed field of view to the pilot, often providing 360° all-round visibility. The designs of bubble canopies can vary drastically; some, such as on later versions of the F4U Corsair, are built into the upper rear fuselage, while others, like the canopy of the P-51D Mustang and most modern combat aircraft, are built flush with the fuselage, providing unobstructed rear visibility. Although experimented with as early as the First World War, the bubble canopy was brought into widespread use during the Second World War, being used by a number of American, British, and Japanese aircraft, commonly fighters. During the postwar era, the bubble canopy became a common feature of jet-powered fighter aircraft. Outside of combat aircraft, such canopies have also been adopted by several helicopters and general aviation aircraft, often for roles that benefit from a high level of exte ...

Chine (aeronautics)
In aircraft design, a chine is a longitudinal line of sharp change in the cross-section profile of the fuselage or similar body. The term chine originates in boatbuilding, where it applies to a sharp profile change in the hull of a boat.Angled chine, different from soft (rounded) chine In a flying boat hull or floatplane float, the longitudinal line of sharp change in cross-section where the bottom plane meets the sidewall is an example of a chine. On some supersonic aircraft a chine extends sideways for some distance, with a very sharp edge blending in with the main wing leading edge root.NASA-AIAA-98-2725 ''Impact of fuselage cross-section on the stability of a generic fighter'' uses "chined-shaped fuselage cross section, chined forebody, fuselage with ... included chine angle" expressions. NASA CR 189641 and AIAA 2008-6228 use "Chine forebody and Chine fuselage" The rest of this article is concerned with this type of chine. Configuration A chine can in aerodynamic terms ac ...

Radome
A radome (a portmanteau of "radar" and "dome") is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas. Radomes can be constructed in several shapes spherical, geodesic dome, geodesic, planar, etc. depending on the particular application, using various construction materials such as fiberglass, polytetrafluoroethylene, polytetrafluoroethylene (PTFE)-coated fabric, and others. In addition to radar protection, radomes on aircraft platforms also act as aircraft fairing, fairings that streamline the antenna system, thus reducing drag (physics), drag. When found on fixed-wing aircraft with forward-looking radar, as are commonly used for object or weather detection, the nose cones often additionally ...

Leading-edge Extension
A leading-edge extension (LEX) is a small extension to an aircraft wing surface, forward of the leading edge. The primary reason for adding an extension is to improve the airflow at high angles of attack and low airspeeds, to improve handling and delay the stall. A dog tooth can also improve airflow and reduce drag at higher speeds. Leading-edge slat A leading-edge slat is an aerodynamic surface running spanwise just ahead of the wing leading edge. It creates a leading edge slot between the slat and wing which directs air over the wing surface, helping to maintain smooth airflow at low speeds and high angles of attack. This delays the stall, allowing the aircraft to fly at a higher angle of attack. Slats may be made fixed, or retractable in normal flight to minimize drag. Dogtooth extension A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapezoidal Wing
In aeronautics, a trapezoidal wing is a straight-edged and tapered wing planform. It may have any aspect ratio and may or may not be swept.G. Dimitriadis; ''Aircraft Design'Lecture 2: Aerodynamics Université de Liège. (retrieved 30 November 2015) The thin, unswept, short-span, low-aspect-ratio trapezoidal configuration offers some advantages for high-speed flight and has been used on a small number of aircraft types. In this wing configuration, the leading edge sweeps back and the trailing edge sweeps forward.Gunston, Bill. ''Jane's Aerospace Dictionary''. London, England. Jane's Publishing Company Ltd, 1980. , Page 436. It can provide low aerodynamic drag at high speeds, while maintaining high strength and stiffness. It was used successfully during the early days of supersonic aircraft. Design principles Any wing with straight leading and trailing edges and with differing root and tip chords is a trapezoid, whether or not it is swept.Tom Benson''Wing Area'' NASA (retrieved ...

Aspect Ratio (aeronautics)
In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area. Thus, a long, narrow wing has a high aspect ratio, whereas a short, wide wing has a low aspect ratio.Kermode, A.C. (1972), ''Mechanics of Flight'', Chapter 3, (p.103, eighth edition), Pitman Publishing Limited, London Aspect ratio and other features of the planform are often used to predict the aerodynamic efficiency of a wing because the lift-to-drag ratio increases with aspect ratio, improving the fuel economy in powered airplanes and the gliding angle of sailplanes. Definition The aspect ratio \text is the ratio of the square of the wingspan b to the projected wing area S, which is equal to the ratio of the wingspan b to the standard mean chord \text: \text \equiv \frac = \frac Mechanism As a useful simplification, an airplane in flight can be imagined to affect a cylinder of air with a diameter equal to the wing ...
