The time period of a pendulum’s oscillation refers to the time it takes for the pendulum to complete one full back-and-forth swing, from one extreme point to the other and back again. It is the time duration of a single oscillation. T is the time period of the pendulum’s oscillation (measured in seconds). π (pi) […]

The power required for stable flight refers to the amount of power that an aircraft’s propulsion system must generate to maintain a steady and level flight at a constant speed. It is the power needed to overcome the total drag force acting on the aircraft. For steady level flight, the lift force is equal to

In flight mechanics, the fineness ratio is the ratio of the length of a body to its maximum width1. In naval architecture and aerospace engineering, the fineness ratio is the ratio of the length of a body to its maximum width. Af is the fineness ratio of the fuselage. l is the length of the fuselage.

The power required for unsteady flight depends on the specific flight maneuver being performed, the changing flight conditions, and the aerodynamic forces acting on the aircraft. Unlike steady level flight, unsteady flight involves changes in velocity, acceleration, and orientation, which make the power required calculation more complex. Preq is the power required for unsteady flight

The wave drag coefficient (Cw) is a dimensionless quantity used in aerodynamics and hydrodynamics to describe the contribution of wave drag to the total drag experienced by an object moving through a fluid (usually air or water) at high speeds. Wave drag is a significant form of drag that occurs when an object’s speed approaches

In flight mechanics, takeoff parameter is a term used to describe the factors that affect the takeoff of an aircraft. The takeoff parameter consists of three important factors: thrust, weight, and wing area1. The takeoff distance consists of two parts, the ground run, and the distance from where the vehicle leaves the ground to until it
