## Induced Inflow Ratio in Hover Solution

STEP 0: Pre-Calculation Summary
Formula Used
Inflow ratio = Induced velocity/(Rotor Radius*Angular Velocity)
λ = vi/(R*ω)
This formula uses 3 Variables
Variables Used
Induced velocity - Induced velocity is used to associate the aerodynamic elements that model the lifting surfaces of an aircraft, or the blades of a helicopter rotor, when some inflow related computations are required. (Measured in Meter per Second)
Angular Velocity - The Angular Velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time. (Measured in Radian per Second)
STEP 1: Convert Input(s) to Base Unit
Induced velocity: 30 Meter per Second --> 30 Meter per Second No Conversion Required
Rotor Radius: 7 Meter --> 7 Meter No Conversion Required
Angular Velocity: 1 Radian per Second --> 1 Radian per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
λ = vi/(R*ω) --> 30/(7*1)
Evaluating ... ...
λ = 4.28571428571429
STEP 3: Convert Result to Output's Unit
4.28571428571429 --> No Conversion Required
4.28571428571429 <-- Inflow ratio
