The Vertical Tail Angle of Attack refers to the angle between the chord line of the vertical tail (fin) of an aircraft and the local relative wind. This angle is crucial in aerodynamics as it influences the lift and, consequently, the yawing moment generated by the vertical tail. Adjusting the vertical tail angle of attack […]

The yawing moment coefficient (Cn) is a dimensionless aerodynamic parameter that describes the rotational force, or moment, experienced by an airfoil or a wing around its vertical axis when subjected to a sideslip angle in an airstream. The yawing moment coefficient provides insight into how an aircraft responds to yawing motion. A positive Cn​ indicates a stabilizing

In flight mechanics, the sidewash angle refers to the angle at which the downward and outward airflow from an aircraft’s wings affects the surrounding air. As the wings generate lift, the resulting airflow creates a vertical component, known as the sidewash. The sidewash angle represents the deviation of this flow from the aircraft’s longitudinal axis.

In flight mechanics, velocity refers to the speed and direction of an aircraft’s motion through the air. It is a crucial parameter influencing various aspects of flight performance, including lift, drag, and maneuverability. If excess power is greater, it generally implies that the aircraft has more power available than is required for maintaining its current

In aircraft, drag force is the resistance encountered by the moving aircraft as it interacts with the air. It acts in the opposite direction to the aircraft’s motion and is influenced by factors like its shape, speed, and surface characteristics. Managing and minimizing drag is essential in aviation for optimizing fuel efficiency, range, and overall

The weight of an aircraft refers to the force exerted by gravity on the entire mass of the aircraft. This force acts vertically downward and is counteracted during flight by the lift produced by the wings. The weight of an aircraft is a critical parameter that influences various aspects of its performance and design. The

Excess power in aviation refers to the surplus power available to an aircraft beyond what is required for level flight. It is a crucial parameter for determining an aircraft’s ability to climb, accelerate, or execute maneuvers. Positive excess power indicates the capacity for climbing, while negative values suggest a power deficiency, leading to descent. The

Centrifugal force in aircraft refers to the outward force experienced by an aircraft during a turn or maneuver, acting away from the center of the curvature. It is a result of the aircraft’s inertia, attempting to move in a straight line while the aircraft is turning. Centrifugal force is essential for maintaining balance in turns

The glide angle is the angle between the trajectory of an aircraft during gliding flight and the horizontal plane. It is a measure of the steepness of the descent path and indicates how efficiently the aircraft can convert altitude into horizontal distance. A shallower glide angle allows for a more extended glide, while a steeper

Lift is the aerodynamic force that acts perpendicular to the relative motion between the body and fluid through which it moves. The lift force is generated primarily by the wings as they interact with the air. Lift opposes the force of gravity (weight), allowing the aircraft to overcome gravitational forces and achieve and maintain flight.
