We will indicate the center of gravity with a circle with black and white quadrants, and we will use \((\bar{x}, \bar{y})\) as the coordinates of this point. This represents the average location of all the particles which make up the body. The same symbols are also used for centroids, and \(\bar{z}\) is used as well for three-dimensional problems.

An aircraft in a steady level turn must have a bank angle φ, equal to V2 φ = arctan gR where R is the turn radius. The turning aircraft also sees a linear relative velocity variation across the span, y u(y) = V 1 − R as shown in Figure 8.
The body axis system, denoted by a subscript \(b\), originates at the aircraft center of gravity. The positive direction of the \(x_b\)-axis is towards the front. The positive direction of the \(y_b\)-axis is towards the right wing tip, and the positive direction of the \(z_b\)-axis is towards the bottom of the aircraft.
Computing the stability of objects in motion like cars, airplanes, and boats: By understanding how the center of gravity interacts with the accelerations caused by motion, we can compute safe speeds for sharp curves on a highway.
19 lut 2023 · I read an article that described static margin by taking the aerodynamic center and the center of gravity. It explained why the center of gravity has to be in front of the aerodynamic center for a stable aircraft. But how does center of pressure play into this?
27 lip 2022 · An airplane in flight can be maneuvered by the pilot using the aerodynamic control surfaces; the elevator, rudder, or ailerons. As the control surfaces change the amount of force that each surface generates, the aircraft rotates about a point called the center of gravity.
