The diameter of a propeller is a critical parameter in aircraft design and performance, as it influences the efficiency and thrust generated by the propeller. Propeller diameter (D) is typically defined as the diameter of the circle that would be described by the tips of the rotating propeller blades. Formula: The diameter of a propeller […]

Thrust Horsepower (THP) required is a measure used in aviation to determine the power needed to overcome drag and maintain level flight. It is a way to express the power requirements of an aircraft.Formula: The formula for Thrust Horsepower (THP) required is as follows: THP is Thrust Horsepower required (in horsepower, hp). T is the

The lift coefficient (Cl) is a dimensionless aerodynamic parameter used to characterize the lift generation of an airfoil or wing. It quantifies the relationship between the lift force generated by the wing or airfoil and various factors like its geometry, angle of attack, and airspeed.Formula: The lift coefficient is typically calculated using the following formula:

The solidity ratio in aerodynamics is a parameter that describes the fraction of an aircraft’s wing area that is occupied by its lifting surfaces, such as wings and flaps. It is used to characterize the openness or “solidity” of the wing. Formula: The solidity ratio (S) is defined as the ratio of the total wing

The wing loading of an aircraft is typically defined as the total weight of the aircraft divided by the wing area. It is expressed in units of force per unit area, such as pounds per square foot (psf) in the Imperial system or newtons per square meter (N/m²) in the SI system. Wing Loading is

Wing loading (W/S) from Range consideration is a parameter that designers and engineers use to evaluate an aircraft’s performance during the takeoff phase. It relates the aircraft’s weight (W) to the wing’s reference area (S) and helps determine the wing’s ability to generate sufficient lift for takeoff. The formula for calculating wing loading from take-off

Wing loading (W/S) from Landing consideration is a parameter that designers and engineers use to evaluate an aircraft’s performance during the takeoff phase. It relates the aircraft’s weight (W) to the wing’s reference area (S) and helps determine the wing’s ability to generate sufficient lift for takeoff. The formula for calculating wing loading from take-off

The instantaneous turn rate (q) is a measure of how quickly an aircraft can change its heading or direction by executing a coordinated turn. It represents the angular rate of rotation (in degrees per second or radians per second) around the aircraft’s vertical axis during the turn. This parameter is crucial for assessing an aircraft’s

Energy height is a measure of an aircraft’s potential energy above a reference point, often the aircraft’s current altitude. It represents the height to which an aircraft could climb if all its kinetic energy (airspeed) were converted into potential energy (altitude) without any thrust or drag. The formula for energy height is as follows:
