The tail rotor is a smaller rotor mounted vertically or near-vertically at the tail of a traditional single-rotor helicopter, where it rotates to generate a propeller -like horizontal thrust in the same direction as the main rotor 's rotation. The tail rotor's position and distance from the helicopter's center of mass allow it to develop enough ...
Jan 11, 2023 · The main rotor blade rotates around a central hub (yellow) with an engine beneath it. A single engine powers both the main rotor blade and the tail rotor. One of Sikorsky's key innovations was to produce a helicopter that needed only one main rotor blade, with a tail rotor to balance it, for reasons discussed below.

Before we jump into the types of tail rotor systems I wanted to quickly explain what the tail rotor system is actually for as this will help you understand each type of system better. A tail rotor system is designed to stop the helicopter from spinning around when it lifts off the ground. As the engine drives the main rotor in one direction, the fu...
Now we know what the role of a tail rotor system is, let’s look at some of the incredible pieces of engineering that prevent today’s helicopters from spinning around! There are four main types of helicopter Anti-Torque system: 1. Bladed Tail Rotor 2. Fenestron Tail Rotor 3. NOTAR 4. No System
The Fenestron is a Trademarked Anti-Torque system used on many Eurocopter, now Airbus Helicopters. This anti-torque system works by placing a multi-bladed fan within a duct in the tail of the helicopter. The duct is integrated into the tail boom and is usually made of a fiberglass skin. The fan consists of between 8-18 blades, depending on the airc...
No matter what type of helicopter is flying they all need some form of anti-torque system to prevent the fuselage from spinning around. The mechanical genius’ that have created the technical wonders you have just read about really do give helicopter operators a vast choice of systems to pick from. When flying in the bush I am always ‘Flying The Tai...
Oct 10, 2022 · The RPM of the tail rotor on the C2 is roughly 2150 RPM. This is a lot lower compared to the Fenestron RPM of roughly 3150 RPM (about 50% higher RPM!). This again, is to make sure the thrust output remains high enough to support the anti-torque required to lift an EC145 from the ground. Smaller blades need more speed to achieve the same amount ...
Oct 29, 2020 · The tail rotor balances the forces generated from the main rotor and also allows the pilot to adjust the direction the nose is pointing when the chopper is hovering. Tail rotors are generally ...
The tail rotor contributes nothing towards thrust generation in hover or forward flight in order to counter the drag and weight of the aircraft - unless canted, the tail rotor of the UH60 is canted by 20 deg which helps it to contribute to lift by about 181 kg [Pro09a]. The tail rotor of the experimental prototype RAH-66 was similarly canted.

Apr 20, 2022 · The mast rotates the upper swash plate and the blades. Transmission — Just as it does in a motor vehicle, a helicopter's transmission transmits power from the engine to the main and tail rotors. The transmission's main gearbox steps down the speed of the main rotor so it doesn't rotate as rapidly as the engine shaft.
