Acceleration is the rate of change of an object’s velocity over time. In aircraft design, acceleration is a crucial parameter as it affects the aircraft’s performance and safety. The formula for acceleration is: SI units for acceleration are meters per second squared (m/s²). In aircraft design, acceleration is often expressed in terms of gravitational acceleration, […]

The angle of incidence in aircraft design refers to the angle at which an aircraft’s wing or other lifting surfaces are attached to its fuselage or body. It is the angle between the longitudinal axis of the aircraft (the centerline running from nose to tail) and the chord line of the wing or lifting surface.

The angle of attack (AOA) in aircraft design refers to the angle between the oncoming air and the chord line of an airfoil (such as a wing or blade). It’s a crucial parameter that affects the lift and drag characteristics of the airfoil and, consequently, the aircraft’s performance.The formula to calculate the angle of attack

The power-to-weight ratio in aircraft design is a crucial metric that measures the engine’s power output relative to the aircraft’s weight. It is defined as: Engine Power is typically measured in watts (W) or horsepower (hp). Aircraft Weight is typically measured in kilograms (kg) or pounds (lb).  

Cargo capacity in aircraft design typically refers to the maximum amount of cargo or freight that an aircraft can carry. It’s an important parameter for airlines and cargo operators when planning flights and determining the suitability of an aircraft for specific routes. The cargo capacity is usually expressed in terms of weight or volume, depending

Wing loading is an important parameter in aircraft design that describes the distribution of an aircraft’s weight (mass) over its wing’s total wing area. It plays a significant role in determining an aircraft’s lift and flight performance characteristics. Wing loading is not represented by a single formula, but rather by a ratio and can be

The aileron span (b_aileron) is the length of the aileron, measured from the root (where it attaches to the wing) to the tip (the outermost point). It is a crucial dimension in aircraft design because it determines the physical size and leverage of the aileron, which directly affects its effectiveness in controlling the roll of

The aileron chord (c_aileron) represents the width or breadth of the aileron, measured from its leading edge to its trailing edge. It’s a key dimension that affects the performance of the aileron in controlling the roll of an aircraft. The formula for calculating the aileron chord is straightforward:Formula: The formula for calculating the aileron chord

The aspect ratio of the aileron is the ratio of its span to its mean chord. It provides an indication of the aileron’s elongation or how long and slender it is. A higher aspect ratio aileron may generate less drag but could be more susceptible to flutter. Aspect ratio is calculated as: Aileron Span (b_aileron)

The Deflection Angle (δ) Of Ailerons on an aircraft is the angle at which these control surfaces are moved to induce a roll motion. The formula for aileron deflection angle is not a single equation but is determined based on aircraft design, control system, and pilot input. Generally, aileron deflection can be represented as: δ
