The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [1] Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft.
[1] [2] [3] An aircraft's gross weight will decrease during a flight due to fuel and oil consumption. An aircraft's gross weight may also vary during a flight due to payload dropping or in-flight refuelling. At the moment of releasing its brakes, the gross weight of an aircraft is equal to its takeoff weight.
It combined a flying wing, or Nurflügel, design with a pair of Junkers Jumo 004 jet engines in its second, or "V2" (V for Versuch) prototype airframe; as such, it was the world's first pure flying wing to be powered by twin jet engines, being first reportedly flown in March 1944. V2 was piloted by Erwin Ziller, who was killed when a flameout ...
The craft was a flying wing design in the shape of an isosceles triangle, with the cockpit situated near the apex of the triangle. [7] The A-12 gained the nickname "Flying Dorito". [7] The aircraft was to be powered by two General Electric F412-D5F2 turbofan engines, each producing about 13,000 pounds-force (58 kN) of thrust.
The Armstrong Whitworth A.W.52 was an early flying wing aircraft designed and produced by British aircraft manufacturer Armstrong Whitworth Aircraft.. The A.W.52 emerged from wartime research into the laminar flow airfoil, which indicated that, in combination with the flying wing configuration, such an aircraft could be dramatically more efficient than traditional designs.
A flying wing is a type of tailless aircraft which has no distinct fuselage. The crew, engines and equipment are housed inside a thick wing, typically showing small nacelles, blisters and other housings.
The position of a swept wing along the fuselage has to be such that the lift from the wing root, well forward of the aircraft center of gravity (c.g.), must be balanced by the wing tip, well aft of the c.g. [68] If the tip stalls first the balance of the aircraft is upset causing dangerous nose pitch up. Swept wings have to incorporate features ...
Mean aerodynamic chord (MAC) is defined as: [6] = (), where y is the coordinate along the wing span and c is the chord at the coordinate y.Other terms are as for SMC. The MAC is a two-dimensional representation of the whole wing. The pressure distribution over the entire wing can be reduced to a single lift force
