WebApr 4, 2024 · The calculation I found was: Thrust = Mass flow rate * (Exhaust Velocity - Free Stream Velocity) ... (1/2 * lift coefficient * air density * area * air speed squared) and treat the fan blades as wings and integrate for the change of speed with radius. I guess the problem is that you could estimate the maximum lift-coefficient to 1 but it could ... WebProp's Output Power = Thrust x Pitch speed Thus, with a given power, the more thrust you have, the less top speed you get. Assuming the same power: Larger diameter & less pitch = more thrust, less top speed. (like the low gear of a car) Smaller diameter & more pitch = less thrust, more top speed. (like the high gear of a car) WebSep 19, 2024 · Input power delivered to a fan is: P_ {in}=V\times I V and I are the electrical voltage (in Volts) and amperage (in Amps). P is measured in Watts.
