Momentum theory treats a propeller as a disk that accelerates the air passing through it, and the reaction is thrust. For a given power, a bigger disk moves more air more gently — producing more thrust at higher efficiency. That is why efficient props and helicopter rotors are large and slow, while jets accept lower efficiency for compactness and speed.

Thrust1383 N

Static thrust2498 N

Induced velocity6.1 m/s

Propulsive eff.83%

Governing equation

T = 2 ρ A (V + v_{i}) v_{i} \approx 1383 N, A = \frac{π}{4} (1.8)^{2} = 2.54 m^{2}

Reading this result: At 30 m/s the prop produces 1383 N at 83% efficiency; wasted energy shows up as the 6.1 m/s slipstream.
