Maximum Blade Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Blade Efficiency = (2*Blade Lift Force/Blade Drag Force-1)/(2*Blade Lift Force/Blade Drag Force+1)
n_bm = (2*F_l/F_d-1)/(2*F_l/F_d+1)
This formula uses 3 Variables

Variables Used

Maximum Blade Efficiency - Maximum Blade Efficiency is the maximum efficiency with which the transfer of energy takes place to the moving blades.
Blade Lift Force - (Measured in Newton) - Blade Lift Force is the sum of all the forces acting on a blade that force it to move perpendicular to the direction of flow.
Blade Drag Force - (Measured in Newton) - Blade Drag Force is the resisting force experienced by the blades moving through a fluid.

STEP 1: Convert Input(s) to Base Unit

Blade Lift Force: 100 Newton --> 100 Newton No Conversion Required
Blade Drag Force: 19.7 Newton --> 19.7 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n_bm = (2*F_l/F_d-1)/(2*F_l/F_d+1) --> (2*100/19.7-1)/(2*100/19.7+1)

Evaluating ... ...

n_bm = 0.820664542558034

STEP 3: Convert Result to Output's Unit

0.820664542558034 --> No Conversion Required

FINAL ANSWER

0.820664542558034 ≈ 0.820665 <-- Maximum Blade Efficiency

n_bm = (2*F_l/F_d-1)/(2*F_l/F_d+1)

What is lift force and drag force?

A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction.

How to Calculate Maximum Blade Efficiency?

Maximum Blade Efficiency calculator uses Maximum Blade Efficiency = (2*Blade Lift Force/Blade Drag Force-1)/(2*Blade Lift Force/Blade Drag Force+1) to calculate the Maximum Blade Efficiency, Maximum blade efficiency refers to the highest level of effectiveness with which a rotor blade converts the available energy in the airflow into useful mechanical energy, typically rotational motion, it represents the optimal performance state of the rotor blade, where it generates the maximum lift or thrust for a given input of power or energy. Maximum Blade Efficiency is denoted by n_bm symbol.
