The coefficient of moment, also known as the pitching moment coefficient, is a dimensionless quantity that measures the tendency of an aerodynamic force to cause a body to rotate about its center of gravity Cmcgwh: Coefficient of moment about the center of gravity due to the weight (gravity) force. Clw: Lift coefficient due to the […]

The lift coefficient due to the weight (gravity) force, often denoted as Clw, refers to the portion of the lift coefficient that is associated with countering the weight of an aircraft. In flight mechanics and aerodynamics, the lift force generated by the wings helps balance the weight of the aircraft, allowing it to maintain level

The coefficient of moment about the center of gravity with respect to the angle of attack is a measure of the pitching moment generated by an aircraft or an airfoil at a given angle of attack (Cmα)w: Coefficient of moment about the center of gravity due to the weight (gravity) force and its effect on

The coefficient of moment about the center of gravity (Cm_cg) in flight mechanics is a dimensionless quantity that relates the moment (torque) generated about the center of gravity of an aircraft to various factors such as angles of attack, control surface deflections, and other aerodynamic characteristics. It’s a crucial parameter used to understand the stability

The total moment about the center of gravity (CG) in flight mechanics refers to the combined rotational effect produced by various forces and torques acting on an aircraft or other object. Moments are responsible for causing rotational motion or changes in angular momentum. M_cg: Total moment about the center of gravity (CG). The equation is

In flight mechanics and aerodynamics, the “mean aerodynamic chord” (MAC) refers to an average chord length that is used to represent the wing planform of an aircraft with a trapezoidal wing shape. The mean aerodynamic chord provides a way to simplify the complex geometry of a trapezoidal wing into a single representative value, which is

In flight mechanics, the “angle of attack,” often denoted as “α” (alpha), refers to the angle between the chord line of an airfoil (such as an aircraft wing) and the oncoming airflow. It’s a critical parameter that describes how the airfoil is positioned with respect to the direction of the oncoming air. α: Angle of

In flight mechanics, the “angle of sideslip,” often denoted as “β” (beta), refers to the angle between the longitudinal axis of an aircraft and its actual flight path through the air. This angle describes how much the aircraft’s heading deviates from the direction it’s moving through the air. β: Angle of sideslip, which is the

In the context of flight mechanics, the time period of oscillation refers to the amount of time it takes for an aircraft’s oscillatory motion to complete one full cycle. Oscillation in flight mechanics can refer to various types of motions, such as vibrations, pitch, roll, or yaw oscillations. These motions are usually repetitive and can

Yawing moment is the moment about the z-axis of an aircraft, which causes it to rotate left or right. It is positive if it moves the nose of the plane to the right, and negative if it moves it to the left. Engine defition is the loss of thrust from one or more engines, which
