Actuator Disk Hover
Estimate induced velocity, ideal hover power, and disk loading from momentum theory.
Hover power
1,096.81 W
790 W ideal / FM 0.72
Induced velocity

1.13 m2 rotor disk area
Hover streamtube
Momentum theory treats the rotor as an actuator disk that accelerates a column of air downward to support thrust.
1.10 kW shaft
Momentum result
vi = sqrt(T / 2 rho A)
Disk loading
