Why can a helicopter ✈️ fly without a tail rotor and still remain perfectly stable? In this video, we explain the amazing coaxial rotor system, where two main rotors spin in opposite directions, cancelling torque automatically. #GearTypes #MechanicalEngineering #GearMechanisms#SpurGear #HelicalGear#BevelGear #WormGear #EngineeringBasics#MechanicalDesign #EngineeringEducation#Machinery #TechExplained#STEM #EngineeringTutorials#RackAndPinion

00:00Why can helicopters without tail rotors fly so steadily?

00:03In a traditional helicopter, the main rotor spins and creates a counter torque

00:07that makes the fuselage twist in the opposite direction.

00:09The tail rotor's job is to cancel that torquey, but it doesn't create lift.

00:13It simply uses part of the engine's power to keep the aircraft balanced.

00:16A coaxial helicopter, however, solves this problem elegantly.

00:19Instead of one main rotor and a tail rotor, it uses two main rotors,

00:23one spinning clockwise, the other counterclockwise.

00:25The opposing torques cancel each other out, keeping the fuselage naturally stable.

00:29This means all of the engine's power goes into lift, with no energy wasted on a tail rotor.

00:33The result? Stronger lift, higher efficiency, and a more compact structure.

00:36By adjusting the blade angles of the two rotors,

00:38the pilot can precisely control movement forward, backward, or turning.

00:41Even in strong winds, the aircraft stays rock-solid, and it can maneuver easily in tight spaces.

00:47Because of this stability and power, coaxial helicopters are often used for heavy lift, rescue, and combat missions.

00:52Hauling cargo over mountains, hovering over ocean rescues, fighting wildfires, or performing low-altitude strikes,

00:58no tail rotor doesn't mean something's missing.
