Stepless (aircraft)
In aircraft design, a stepless cockpit means that the nose of the aircraft has no separate "windscreen" panels directly in front of the pilot's or co-pilot's seating positions, and generally has no "breaks" in the nose contour – curved or otherwise – from their absence. In the conventional design, the pilot's cabin is a different part of the aircraft than the nose. The stepless design is believed to help make the plane more aerodynamic thus aiding speed and fuel efficiency Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, wh .... The stepless design did, however, present serious challenges to the inclusion of a nose-mount turreted gun position, in eras where manned or remotely-aimed gun turrets were still important for a bomber's defensive needs.

Boeing 787 First Flight
The Boeing Company () is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, satellites, telecommunications equipment, and missiles worldwide. The company also provides leasing and product support services. Boeing is among the largest global aerospace manufacturers; it is the third-largest defense contractor in the world based on 2020 revenue, and is the largest exporter in the United States by dollar value. Boeing stock is included in the Dow Jones Industrial Average. Boeing is incorporated in Delaware. Boeing was founded by William Boeing in Seattle, Washington, on July 15, 1916. The present corporation is the result of the merger of Boeing with McDonnell Douglas on August 1, 1997. Then chairman and CEO of Boeing, Philip M. Condit, assumed those roles in the combined company, while Harry Stonecipher, former CEO of McDonnell Douglas, became president and COO.

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometer ...

Heinkel He 111 P-2 (Wk Nr 1526) (6956565308) (4)
Heinkel Flugzeugwerke () was a German aircraft manufacturing company founded by and named after Ernst Heinkel. It is noted for producing bomber aircraft for the Luftwaffe in World War II and for important contributions to high-speed flight, with the pioneering examples of a successful liquid-fueled rocket and a turbojet-powered aircraft in aviation history, with both Heinkel designs' first flights occurring shortly before the outbreak of World War II in Europe. History Following the successful career of Ernst Heinkel as the chief designer for the Hansa-Brandenburg aviation firm in World War I, Heinkel's own firm was established at Warnemünde in 1922, after the restrictions on German aviation imposed by the Treaty of Versailles were relaxed. By 1929, the firm's compressed air-powered catapults were in use on the German Norddeutscher Lloyd ocean-liners and to launch short-range mail planes from the liners' decks. The company's first post-World War I aircraft design success was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive-drab Painted B-29 Superfortress
Olive is a dark yellowish-green color, like that of unripe or green olives. As a color word in the English language, it appears in late Middle English. Shaded toward gray, it becomes olive drab. Variations Olivine Olivine is the typical color of the mineral olivine. The first recorded use of ''olivine'' as a color name in English was in 1912. Olive drab Olive drab is variously described as a "dull olive-green colour" (''Oxford English Dictionary'');''Oxford English Dictionary'', 5th Edition, 1982 "a shade of greenish-brown" (''Webster's New World Dictionary''); "a dark gray-green" (''MacMillan English dictionary''); "a grayish olive to dark olive brown or olive gray" (''American Heritage Dictionary''); or "A dull but fairly strong gray-green color" (''Collins English Dictionary''). It was widely used as a camouflage color for uniforms and equipment in the armed forces, particularly by the U.S. Army during the Second World War. The first recorded use of ''olive ...
