Propeller Speed Reduction Torque Increase Explained

Support me on Patreon :   / letsgoaviate   In this video I'll explain in simple terms (and also cover the math) how a Propeller Speed Reduction Unit / PSRU / redrive actually increases torque on an airplane engine/propeller. If it didn't make sense before, it will after watching this video. We'll also cover the advantages and disadvantages of an engine making use of a gearbox to reduce propeller speed.
