In flight mechanics, the “drag coefficient” (CD) in turning flight refers to the dimensionless parameter that quantifies the drag force acting on an aircraft during a turn. It is a crucial factor in understanding the aerodynamic performance of the aircraft while maneuvering.
Ta / (0.5 * ρ * V^2 * S)
- Ta: Thrust force acting on the aircraft. It is the force generated by the aircraft’s engines or propulsion system to overcome drag and provide forward thrust.
- ρ: Air density. It is the mass of air per unit volume and depends on altitude and atmospheric conditions.
- V: Airspeed or true airspeed of the aircraft.
- S: Reference area of the aircraft. In the context of the Thrust-to-Drag Ratio, it is usually the wing area.
