To find the center of gravity, we divide the total moment by the total weight: 193,193 / 2,055 = 94.01 inches behind the datum plane. In larger aircraft, weight and balance is often expressed as a percentage of mean aerodynamic chord, or MAC. For example, assume the leading edge of the MAC is 62 inches aft of the datum.
is the weight. Since the load factor is the ratio of two forces, it is dimensionless. However, its units are traditionally referred to as g, because of the relation between load factor and apparent acceleration of gravity felt on board the aircraft. A load factor of one, or 1 g, represents conditions in straight and level flight, where the lift ...
Weight acts through the aircraft's centre of gravity, towards the centre of the Earth. In straight and level flight, lift is approximately equal to the weight, and acts in the opposite direction. In addition, if the aircraft is not accelerating, thrust is equal and opposite to drag. [3] In straight climbing flight, lift is less than weight. [4]
The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
where g is the acceleration due to gravity at the Earth's surface. The acceleration along the trajectory is equal to the net x-wise force minus the component of weight. We should not expect significant aerodynamic derivatives to depend on the flight path angle, so only and need be considered.
Gravity – (from Latin gravitas 'weight' [95]), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light [96] —are attracted to (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the
Low-g condition is a phase of aerodynamic flight where the airframe is temporarily unloaded. The pilot—and the airframe—feel temporarily "weightless" because the aircraft is in free-fall or decelerating vertically at the top of a climb. It may also occur during an excessively rapid entry into autorotation.
In steady level longitudinal flight, thrust counterbalances drag and lift supports the aircraft's weight. Lift and drag are components of the aerodynamic force. Steady flight , unaccelerated flight , or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference ...
