The Blériot-Spad S.45 was a large, four engine French airliner which appeared at the 1921 Paris Salon. It could carry fifteen passengers or be adapted as a bomber .

28-400: A sailboat forward are the same that create lift for an airplane. The term leading edge refers to the part of the sail that first contacts the wind. A fine tapered leading edge that does not disturb the flow is desirable since 90% of the drag on a sailboat owing to sails is a result of vortex shedding from the edges of the sail. Sailboats utilize a mast to support the sail. To help reduce
42-430: A cylindrical Lamblin radiator mounted in pairs between the engine nacelles. Its fuselage was a wooden, circular section monocoque built from cross-grained layers of spruce and tulipwood . The three crew sat in individual open cockpits near the nose, with the navigator in front where large windows in the lower nose gave him a wide view of the ground and the two pilots side-by-side behind. Fifteen passengers sat in

70-403: A mid-fuselage mounted tailplane and a fin carrying a rather pointed, balanced rudder . The S.45 was powered by four 275 hp (205 kW) Hispano-Suiza water-cooled V8 engines , two, close together in pusher configuration on top of the upper wing and two, further apart, on the lower wing in tractor configuration . Fuel was held in two upper wing tanks and each engine was cooled with

98-477: Is the part of the wing that first contacts the air; alternatively it is the foremost edge of an airfoil section. The first is an aerodynamic definition, the second a structural one. As an example of the distinction, during a tailslide , from an aerodynamic point of view, the trailing edge becomes the leading edge and vice versa but from a structural point of view the leading edge remains unchanged. The structural leading edge may be equipped with one or more of
112-536: The General Dynamics F-111 , have swing-wings where the sweep of both wing and leading edge can be varied. In high-speed aircraft, compression heating of the air ahead of the wings can cause extreme heating of the leading edge. Heating was a major contributor to the destruction of the Space Shuttle Columbia during re-entry on February 1, 2003. When sailing into the wind, the dynamics that propel
126-418: The enclosed cabin on seats arranged in five rows with two seats on the starboard side, one on the port side and a corridor between them. Each row had a window on either side. Entry was via a starboard-side door. There was a baggage space and a two seat toilet at the back. The S.45 had a fixed, conventional undercarriage with a tailskid but its weight required more than the usual two mainwheels. Instead there
140-439: The following: Associated terms are leading edge radius and leading edge stagnation point . Seen in plan the leading edge may be straight or curved. A straight leading edge may be swept or unswept, the latter meaning that it is perpendicular to the longitudinal axis of the aircraft. As wing sweep is conventionally measured at the 25% chord line an unswept wing may have a swept or tapered leading edge. Some aircraft, like

#1732852571576168-409: The single upper and lower spars and the ply-covered leading edge D-boxes. The lower wings were conventionally mounted to the lower fuselage and the upper wing was held high above the fuselage by a frame including outward leaning members from just outside the engines to the fuselage. Ailerons filled the entire trailing edge of the lower wing beyond a central cut-out. The tail was conventional, with
182-510: Was a large, French biplane airliner built shortly after the end of World War I . It was designed by André Herbement and retained some of the characteristics of his earlier, smaller Blériot-SPAD airliners, notably the combination of a swept upper wing with a smaller, unswept lower one. It was his first four engine aircraft and was of largely wooden construction. Despite its size it was a single bay biplane braced by single, outwards-leaning interplane struts with large feet which reached between
196-542: Was a pair of wheels in tandem under a shared fairing on each side. These were joined by a horizontal cross-member with its ends on V-struts to the fuselage, each stiffened laterally with a further strut. Despite the interest it attracted at the 1921 Salon, there is no known record of it flying. It was still under construction not long before the Salon.
