SUMMARY
The calculation of lift capacity for rotor blades in helicopters is primarily determined by engine horsepower and the transfer of that power to thrust. Key factors include the RPM of the blades, blade size, and pitch adjustments, specifically collective and cyclic pitch. Induced drag losses mean that less than 75% of the engine's output is available for lift, and various environmental conditions such as elevation, temperature, and humidity significantly affect performance. For accurate calculations, consulting an aircraft's operator manual is essential, as real-world variables complicate theoretical estimates.
