How to calculate stall velocity

WebFriction drag + Pressure drag + Compression drag + Lift induced drag. Due the effect of camber on the wing minimum drag is usually at a positive lift coefficient to make flight more efficient. So drag coefficient can be related to lift coefficient as. C D = C D 0 + K ( C L − C L 0) 2. where C D 0 represents the friction and pressure drag ... WebThe formula for calculating the stall speed of an airplane is: Stall speed = √ (2 x weight / (density x wing area x lift coefficient)) The weight is the total weight of the aircraft, …

WebHow to calculate torque from rpm and hp? The main methods of measuring torque are using RPM, which is revolutions per minute, and HP, horsepower. First Method. Torque = 63025 x Power (Measured in HP) / Speed (Measured in RPM) Second Method. Power (Measured in HP) = Torque x Speed (Measured in RPM) / 63025. Third Method. WebGiven: W = 56,000 lbs VTO = 1.2 Vstall p = 75% S = 1000 ft2 T 0 = 2400 BHP/engine CLmax = 2.4 = 0.25 This is a propeller driven aircraft with a shaft (brake) horsepower of 2400 per engine.

Web23 feb. 2024 · Drag Force: It can be defined as the amount of drag or resistance offered to a moving body or an object in a fluid medium, such as water and air. The drag force acts opposite to the direction of oncoming flow velocity. This is the relative velocity between the and fluid. In common it is the force that is exerted on a solid object moving with ... Web26 feb. 2024 · Boldmethod So if the stall speed (Vs - clean config) in your Cessna 172 is 48 knots, then your stall speed at 60 degrees of bank is 48 knots X 1.41, which equals just over 67 knots. Putting It All Together When you turn, you need to increase your total lift to maintain altitude.
