Douglas DC-1The Douglas DC-1 was the first model of the famous American DC (Douglas Commercial) commercial transport aircraft series. Although only one example of the DC-1 was produced, the design was the basis for the DC-2 and DC-3, the latter being one of the most successful aircraft in the history of aviation.
United Aircraft and Transport CorporationThe United Aircraft and Transport Corporation was an American company from February 1929 to September 1934, based in Hartford, Connecticut. The company was formed in 1929. William Boeing of Boeing Airplane & Transport Corporation teamed up with Frederick Rentschler of Pratt & Whitney. Together, they formed a large, vertically-integrated, amalgamated firm. The firm united business interests in all aspects of aviation.
History of United AirlinesUnited Airlines was formed in 1931 as a subsidiary of United Aircraft and Transport Corporation to manage a group of airlines controlled by William Boeing, including Boeing Air Transport, National Air Transport, Pacific Air Transport and Varney Air Lines, all of which held U.S. Air Mail contracts. Of its predecessor companies, the first to commence cargo (airmail) operations was Varney Air Lines on April 6, 1926, a date United later celebrated as its centenary.
Deutsche Luft HansaDeutsche Luft Hansa A.G. (from 1933 styled as Deutsche Lufthansa and also known as Luft Hansa, Lufthansa, or DLH) was a German airline, established in 1926. It served as the flag carrier of the country during the later years of the Weimar Republic and throughout the era of Nazi Germany, when it had close links to the Nazi Party. It ceased operations in April 1945, in the final stages of the Second World War.
AirlinerAn airliner is a type of airplane for transporting passengers and air cargo. Such aircraft are most often operated by airlines. The modern and most common variant of the airliner is a jet powered aircraft with a long, tube-shaped fuselage. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin.

AutopilotAn autopilot is a system used to control the path of an aircraft without requiring constant intervention by a human operator. The autopilot does not replace human operators, but it assists them allowing them to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems). When present, an autopilot is often used in conjunction with an autothrottle, a system for controlling the power delivered by the engines.
Landing gearLanding gear is the undercarriage of an aircraft or spacecraft that is used for engaging the surface — typically land, but may also be the surface of a water body — when parking, taxiing, taking off or landing. 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).
CantileverA cantilever is a structural element that is firmly attached to a fixed structure at one end and is unsupported at the other end. Sometimes it projects from a vertical surface such as a wall. A cantilever can be in the form of a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment.
TailplaneA tailplane, also known as a horizontal stabiliser, is a small lifting surface located on the tail (empennage) behind the main lifting surfaces of a fixed-wing aircraft. Gyroplanes and some helicopters also feature horizontal stabilisers as part of their tail assembly. Not all fixed-wing aircraft have tailplanes.
Trim tabTrim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface.
Deicing bootA deicing boot is a type of ice protection system installed on aircraft surfaces to permit a mechanical deicing in flight. Such boots are generally installed on the leading edges of wings and control surfaces (e.g. horizontal and vertical stabilizer) as these areas are most likely to accumulate ice which could severely affect the aircraft's performance.
AnodizingAnodizing is an electrolyticpassivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.*As an Amazon Associate I earn from qualifying purchases.
