NOTAR Technology
The NOTAR® anti-torque system eliminates all of the mechanical disadvantages of a tail rotor, including long drive shafts, hanger bearings, intermediate gearboxes, and ninety-degree gearboxes. Using the natural characteristics of helicopter aerodynamics, the NOTAR system provides safe, quiet, responsive, FOD-resistant directional control.
The enclosed variable-pitch composite blade fan produces a low-pressure, high volume of ambient air to pressurize the composite tail boom.
The air is expelled through two slots that run the length of the tail boom on the starboard (right) side, causing a boundary-layer control called the Coanda Effect. The result is that the tail boom becomes a “wing,” flying in the downwash of the rotor system, producing up to 60 percent of the anti-torque required in a hover. The balance of the directional control is accomplished by a rotating direct jet thruster. In forward flight, the vertical stabilizers provide the majority of the anti-torque. However, directional control remains a function of the direct jet thruster.
There are two production helicopters that utilize the NOTAR system, both produced by MD Helicopters.
- Greater Safety: Studies have shown that 21% of all crashes are due to tail rotor strikes or loss of tail rotor effectiveness. NOTAR® systems eliminate these problems.
- Reduced Noise: Designed and tested to be 50% quieter, NOTAR-equipped helicopters are among the quietest certified helicopters available.
- Reduced Pilot Workload: Using the Coanda Effect to provide tail boom lift and anti-torque, the system is more stable and easier to control. This effect reduces the sensitivity to wind direction on helicopter control.
- Reduced Aircraft Vibration: The inherent stability of the standard MD 500 is further improved by the elimination of the exposed tail rotor assembly, which reduces overall helicopter vibrations and increases passenger comfort while reducing pilot fatigue.
Parts
All sales of spare parts and kitting for the MD Helicopters fleet is handled by the Spares Sales department, via our MD Helicopters Authorized Service Centers and Spare Parts Retailers. This is to ensure all aircraft sustainment, aftermarket services, and customer satisfaction is met.
All MDH Authorized Service Centers are required to stock spare items in sufficient quantities to support the number of helicopters in their geographic areas.
