The NOTAR (no tail rotor) patent is an anti-torque system replacement for helicopter tail rotors with a standard configuration. Production models that are currently available with the NOTAR system are the MD Explorer, MD 600N, and the MD 520/530N. This unconventional system implements circulation control around the tail boom (Coanda effect) that allows the tail boom to act as a wing that produces lateral lift allowing the helicopter to hover. Circulation control is being used extensively for improving the aerodynamic characteristics of rotorcraft airfoils. Some benefits of circulation control have increased the lift to drag ratio and lowered the drag coefficient. The absence of a tail rotor is very beneficial for many reasons. While on the ground, there is no invisible tail rotor disk that ground personnel or (de)boarding passengers can walk into. While in hover, trees are of no concern for the rotor-less tail boom. The NOTAR system is not as susceptible as a tail rotor to foreign object interference, such as rocks or other thrown projectiles. NOTAR helicopters have decreased decibel (db) output, and have reasonable maintenance requirements. This paper will give a brief overview of the circulation control technology used on the NOTAR helicopter. Also, the advantages and challenges of this technology are presented along with the application of this on the NOTAR helicopters.
