I know the lift force equation is .5*rho*V^2*Area*Coefficient. But I was wondering in the real world how would you measure the lift force? I hope they don't just plug the values for the equations.
You could do this simply with a spring scale and something to constrain the rotor group to the scale and something to drive it. It is even easier if you have a strain gauge based force transducer because then there would be no axial movement due to the thrust.fujifilm6502002 said:I was wondering like if you are building your own helicopter what would someone use to test the amount of thrust produced by the rotor?
To test it, you mount it on a test rig and measure the forces.fujifilm6502002 said:I was wondering like if you are building your own helicopter what would someone use to test the amount of thrust produced by the rotor?

The lift force of a helicopter in hover refers to the vertical force that is generated by the rotor blades. This force is responsible for keeping the helicopter airborne and counteracting the force of gravity.
The lift force of a helicopter in hover can be determined by calculating the amount of air that is being moved by the rotor blades and the force it produces. This is known as the lift equation and takes into account factors such as the air density, rotor blade area, and blade pitch.
In order to accurately measure the lift force of a helicopter in hover, instruments such as a dynamometer, a load cell, and a force sensor are commonly used. These instruments are capable of measuring the force produced by the rotor blades in real time.
The lift force of a helicopter in hover can vary depending on the design of the rotor blades. Factors such as the shape, size, and angle of the blades can affect the amount of lift force they can generate. Generally, larger and more angled blades can produce more lift force.
Yes, there are external factors that can affect the lift force of a helicopter in hover. These include changes in air density due to altitude, temperature, and humidity, as well as wind speed and direction. These factors can impact the performance of the rotor blades and ultimately affect the lift force of the helicopter.
