The word "tail rotor" refers to a specialized helicopter rotor located at the end of the tail boom. The correct spelling is /teɪl ˈroʊtər/, with an "a" in "tail" and a "o" in "rotor". This is because the "a" in "tail" is pronounced with an open front vowel (/eɪ/) and the "o" in "rotor" is pronounced with a mid-back, rounded vowel (/oʊ/). The correct spelling of "tail rotor" is important for pilots and aviation professionals to ensure clear communication and safety during helicopter operations.
A tail rotor is a key component in helicopters and some aircrafts designed to counteract the torque generated by the main rotor. Typically positioned at the tail end of the aircraft perpendicular to the main rotor, it consists of a small rotor system driven by the main transmission. The primary purpose of the tail rotor is to produce a reactive torque in the opposite direction of the main rotor's torque, thereby maintaining the stability and balance of the aircraft during flight.
The tail rotor helps prevent the helicopter's fuselage from spinning in the opposite direction to the main rotor as the engine and main rotor spin in one direction. By doing so, it ensures the authorized direction of flight for the aircraft. The tail rotor's orientation can be regulated by the pilot through controls, allowing for adjustments in thrust, pitch, and RPM (rotations per minute), tailored to specific flight maneuvers or conditions.
The tail rotor's efficiency and effectiveness are crucial for maintaining control and stability, especially during hovering, low-speed flight, or challenging flight conditions. It is designed to vary the amount of thrust generated, assisting in steering the aircraft, counteracting the impact of crosswinds, and correcting yaw deviations. The tail rotor's size, structure, and material composition are carefully engineered to facilitate its essential functions while minimizing mechanical vibrations and noise production.
In summary, the tail rotor is an integral part of helicopters and some aircraft that generates torque in the opposite direction to the main rotor, ensuring stability, control, and proper flight direction by counteracting the torque produced by the main rotor system.

The word "tail rotor" is a compound noun consisting of two components: "tail" and "rotor".
The term "tail" comes from the Old English word "tægl", which means "the hinder part of an animal, extending beyond the trunk". Over time, it evolved to refer to the hindmost or rear part of an object or structure. In the context of helicopters, "tail" refers to the rear section of the aircraft.
The word "rotor" originated from the Latin word "rota", which means "wheel". It refers to a rotating mechanism that produces lift or thrust. In the case of helicopters, the rotor refers to the rotating blades that generate lift and allow the aircraft to hover, take off, and land vertically.
