To better understand AOA on lift force and lift coefficient, engineers have studied how the AOA changes the way a plane flies. If you graph lift coefficients against AOA, you can calculate the positive value of the slope, which is known as the two-dimensional lift-curve slope. Research has ...
As the chart demonstrates, the intercycle ice simulations had a more severe effect on maximum coefficient of lift ([C.sub.I], max, or ability to produce lift--higher is better) for the NACA 23012 airfoil. Wing shape and ice: some airplane wing designs handle icing better than others. Bu...
The Lift Coefficient In determining the lift of a given airfoil, engineers refer to its lift coefficient. This number depends on air speed, air density, wing area and angle of attack. Aerial Navigation: Stabilizers, Ailerons, Rudders and Elevators The tail of the airplane has two types of...
As wind moves over the car in the tunnel, computers are used to calculate the drag coefficient (Cd). Wind tunnels are really nothing new. They've been around since the late 1800s to measure airflow over many early aircraft attempts. Even the Wright Brothers had one. After World War II,...
Motor KV to RPM Calculation In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article onhow to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rot...
Answer to: A ride at an amusement park has a 55m drop. The rollercoaster has a mass of 8,000 kg. How fast will it be travelling when it reaches the...
The CRF has nothing to do with how much traction the tire has; it is used to calculate the amount of drag or rolling resistance caused by the tires. The CRF is just like any other coefficient of friction: The force required to overcome the friction is equal to the CRF multiplied by ...
A is wing area, Cl is the lift coefficient (usually determined experimentally); you see - more speed, more lift. There is another reason. If you would have huge wings forces acting on them while performing a barrel roll would be so strong that would break them. But how you can increase...

It is a measurement of heat energy, but the measurement can be converted to another energy measurement system. A single BTU represents the amount of heat required for a pound of water to increase its temperature by one degree Fahrenheit.
