The positive roll rate (p) is a measure of the rate at which an aircraft rotates about its lateral axis (roll axis) in the positive or right-roll direction. This is typically controlled by the ailerons and is crucial for controlling the aircraft’s roll motion during maneuvers. The formula for the positive roll rate (p) can […]

In aircraft design, the vertical stabilizer primarily generates lift in the sideways direction, which helps maintain the aircraft’s lateral stability and counteract side-to-side yawing motion. This lift is often referred to as “side force.”The formula for calculating the side force (lift) generated by the vertical stabilizer can be expressed as: Side Force (Lateral Lift) is

In aircraft design, the horizontal stabilizer primarily generates lift in the downward direction, which is opposite to the wing’s lift. This downward lift helps to counteract the aircraft’s nose-up pitching moment and maintain longitudinal stability. The lift generated by the horizontal stabilizer is typically referred to as “negative lift” or “downforce. “The formula for calculating

The moment coefficient (Cm) for an aircraft’s horizontal stabilizer, also known as the tailplane, represents its aerodynamic effectiveness in generating or changing the pitching moment of the aircraft. This is important for controlling the aircraft’s pitch and maintaining longitudinal stability. The formula for calculating the moment coefficient (Cm) of the horizontal stabilizer is as follows:

The aspect ratio (AR) of an aircraft’s horizontal stabilizer (also known as the tailplane) is defined as the ratio of its span (b) to its average chord length (c). The formula for calculating the aspect ratio of the horizontal stabilizer is as follows: Aspect Ratio (AR) is a dimensionless quantity; it has no SI units

The area (Ah) of the horizontal stabilizer in aircraft design is typically calculated as the product of its span (b) and its average chord length (c). The formula can be expressed as: Area (Ah) is the area of the horizontal stabilizer, measured in square meters (m²). Span (b) is the distance from one end of

The mass of the horizontal stabilizer in aircraft design is a critical consideration, as it contributes to the overall weight and balance of the aircraft. In general, the mass (m) of the horizontal stabilizer can be calculated using the following equation Mass (m) is the mass of the horizontal stabilizer, typically measured in kilograms (kg).

The formula for calculating the area of the horizontal stabilizer in aircraft design is quite straightforward. The area (Ah) of the horizontal stabilizer is typically calculated as the product of its span (b) and its average chord length (c). The formula can be expressed as: Area (Ah) is the area of the horizontal stabilizer, measured

The horizontal stabilizer, also known as the tailplane or horizontal tail, is an essential component of an aircraft’s design used to control its pitch and maintain stability in the longitudinal axis. The key parameter for the horizontal stabilizer is often its lift coefficient (Cl). The formula for calculating the lift coefficient (Cl) of the horizontal

The moment coefficient (Cm) in aircraft design represents the aerodynamic effectiveness of a control surface or an airfoil in generating or changing the pitching moment of an aircraft. Pitching moment refers to the rotational force that tends to pitch the nose of the aircraft up or down. The formula for the moment coefficient (Cm) is
