Notes

This function performs several tasks:

Designs the rotor based on its type (propeller, lift rotor, or prop rotor)
Sets the motor design parameters based on the rotor requirements
Designs the motor for optimal performance
Computes the motor weight
Calculates the sea level static performance (thrust and power)

The function handles different types of rotors:

For propellers, it uses the design_propeller function and sets the motor design parameters based on cruise conditions
For prop rotors, it uses the design_prop_rotor function and sets the motor design parameters based on hover conditions
For lift rotors, it uses the design_lift_rotor function and sets the motor design parameters based on hover conditions

Major Assumptions

US Standard Atmosphere 1976 is used for atmospheric properties
Sea level static conditions are approximated with a very low velocity (1% of speed of sound)
Full throttle (throttle = 1.0) is used for sea level static performance
