High Gear Ratio vs Low Gear Ratio
The relationship of the Torque, Thrust and Gear Ratio
The torque that is produced by the engine is converted to thrust by the combined effect of the gear ratio with our propeller. Physics teaches us that the Torque is proportional to the horsepower (Hp) and inversely proportional to the rotation speed (Rpm). Thus, the higher the horsepower or the lower the rpm of the propshaft is, the greater the torque that is produced gets.
As the torque at the propeller shaft increases, so a larger diameter propeller can rotate.
