How many stages of reduction occur in the transmission?

The transmission of the Trainer Helicopter, Design Number 73 (TH-73), features two stages of reduction. This design is intended to effectively convert the high-speed rotation of the engine’s output shaft into a lower-speed, higher-torque output suitable for the main rotor. The first stage typically consists of the initial gear reduction, where the engine speed is significantly decreased. The second stage further reduces the speed of the output from the first stage, ensuring that the rotational speed delivered to the rotor system meets the operational requirements efficiently. This two-stage reduction system not only optimizes performance but also enhances the durability and load-carrying capacity of the transmission system. By utilizing multiple reduction stages, the TH-73 is able to maximize efficiency and maintain engine performance, while allowing for smooth operation of the rotor blades.
