Helicopter drive shafts are critical components that transmit power from the engine(s) to the main and tail rotors while enduring extreme mechanical stresses, vibrations, and operational conditions. Their design must meet stringent requirements to ensure reliability, safety, and performance.
Aero engine shafts, especially those in gas turbine engines (turbojets, turbofans, turboprops, and turboshafts), must meet extremely stringent requirements due to the high stresses, temperatures, and rotational speeds involved.
