[edit] History
McDonnell Douglas Helicopter Systems (MD Helicopters since 1999) first announced it was developing a stretched MD 520N in late 1994, at that time designated the MD 630N.[1] The prototype, a modified MD 530F, had made its first flight on November 22 1994. McDonnell Douglas gave the go-ahead for the production aircraft, redesignated the MD 600N, in March 1995.
McDonnell Douglas stretched the MD 520N fuselage by inserting a plug aft of the cockpit/cabin bulkhead and stretching the NOTAR tail boom. The larger fuselage allows for an extra (middle) row of seats. Other differences compared with the MD 520N include a new six blade main rotor (the MD 520N has a five blade unit) and a more powerful Allison (now Rolls-Royce) 250 turboshaft.
The prototype was modified to MD 600N standard with a production standard engine and tail boom and flew in November 1995, followed the next month by the first MD 600N production prototype.[1] Certification was awarded on May 15 1997, and deliveries began that June.
Following the 1997 Boeing/McDonnell Douglas' merger, Boeing sold the former MD civil helicopter lines to Netherlands-based RDM Holdings in early 1999.[1]
[edit] NOTAR
The NOTAR no-tail-rotor version is popular with law enforcement because of its very low noise levels. Instead of an anti-torque tail rotor, a fan exhaust is directed through slots in the tail boom, using the Coanda effect to counteract the torque of the main rotor, and out of a controllable thruster at the end of the tail boom for yaw control
