One taut-line hitch is tied 15–30 cm from the aircraft and adjusted for tension, then a second taut-line hitch is tied 5–20 cm further from the aircraft and finished with a half-hitch. Wind-induced lift tends to pull the knot tighter, gust-induced oscillations tend to damp-out, and once the half hitch is undone, pushing the lower working ...
A typical metal spar in a general aviation aircraft usually consists of a sheet aluminium spar web, with L- or T-shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads. Larger aircraft using this method of spar construction may have the spar caps sealed to provide integral fuel tanks.
Three Dornier 228 of Aerocardal at the airline's Arturo Merino Benítez International Airport base. A fixed-base operator (FBO) is an organization granted the right by an airport to operate at the airport and provide aeronautical services such as fueling, hangaring, tie-down, and parking, aircraft rental, aircraft maintenance, flight instruction, and similar services.

Analytical techniques such as this led to lighter and stronger aircraft and became widely adopted. At the same time, the amount of bracing could be progressively reduced. At low speeds a thin wire causes very little drag and early flying machines were sometimes called "bird cages" due to the number of wires present.
Basic aircraft control surfaces and motion. A)aileron B)control stick C)elevator D)rudder. Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. Development of an effective set of flight control surfaces was a critical advance in the development of aircraft.
Cleco (Cleko) fasteners on an aircraft wing. A cleco, also spelled generically cleko, is a temporary fastener developed by the Cleveland Pneumatic Tool Company. [1] Widely used in the manufacture and repair of aluminum-skinned aircraft, it is used to temporarily fasten sheets of material together, or to hold parts such as stiffeners, frames etc together, before they are permanently joined.
Douglas Aircraft Company responded in 1942 with a giant four-engined design. Development and production modifications issues with the aircraft caused the first flight to be delayed until 5 September 1945, after both V-J Day (marking the end of conflict in World War II, on August 15, 1945) and formal surrender on September 2. Total production ...
The Boeing 787, first flown in 2009, was the first commercial aircraft with 50% of its structure weight made of carbon-fiber composites, along with 20% aluminium and 15% titanium: the material allows for a lower-drag, higher wing aspect ratio and higher cabin pressurization; the competing Airbus A350, flown in 2013, is 53% carbon-fiber by ...
