The MD-902 helicopter, one of the safest and quietest helicopters in the world, features MD’s No Tail Rotor (NOTAR system), marking a revolution in helicopters.
McDonnell Douglas Helicopters began development of the new MD-902 helicopter, designated MDX, in 1989, using Boeing, NOTAR reverse torque technology and the PW207E family of engines. The MD-902 was the most technologically advanced helicopter of its time and was modified over the years to enhance performance and flexibility. It is suitable for intra-city and inter-airport use.
It is a member of MD’s famous series of tail rotorless (NOTAR system) helicopters, with a longer fuselage than the 500 series, which no longer looks like a “flying egg”. Thanks to the elimination of the tail rotor, flight vibration is minimal.
The MD 600N is a light single-engine turboshaft helicopter with high performance, high operational capability, versatility and low operating costs. Thanks to its advanced NOTAR anti-torque system, the MD 600N is one of the safest and quietest members of the world’s private helicopter family.
As a versatile mission performer, the MD 600N can be modified to suit a variety of uses. Its fuselage design is structurally clean and incorporates aerodynamic lines. The three-dimensional rigid truss “A-frame” design feature reduces the possibility of recessing the fuselage into the cockpit and passenger compartment, thus improving crew safety.
The patented NOTAR System Tail Rotorless Anti-Torque System eliminates the tail rotor system, which is a revolution in helicopter design. It eliminates the hazards associated with tail rotor collisions during flight or while parked on the ground, as well as the reduced component life, increased maintenance costs and pilot fatigue associated with the noise and vibration generated by conventional tail rotors. The aircraft can be used for a wide range of flight activities such as news gathering, administrative transport, air medical rescue, air tours and air law enforcement support.
