About the MCDONNELL DOUGLAS HELICOPTER MD 900
The McDonnell Douglas Helicopter MD 900, also known as the MD Explorer, represents a significant advancement in rotary-wing technology for general aviation. Developed in the early 1990s, the MD 900 was introduced to meet the growing demands for a versatile, high-performance, and safe helicopter, particularly in fields such as emergency medical services (EMS), law enforcement, and corporate transport. The aircraft's development was driven by the need for a lightweight, twin-engine helicopter that could offer exceptional maneuverability, reduced noise levels, and increased safety features.
The MD 900's production history began with its first flight in December 1992 and subsequent FAA certification in 1994. One of the most remarkable features of the MD 900 is its NOTAR (No Tail Rotor) system. This innovative design eliminates the traditional tail rotor, utilizing a fan within the tail boom to provide anti-torque control. The NOTAR system significantly enhances safety by reducing the risk of tail rotor strikes and decreasing noise levels, making the MD 900 particularly suitable for operations in urban environments.
Key Features and Capabilities
In terms of performance, the MD 900 is powered by two Pratt & Whitney Canada PW206A turboshaft engines, providing the necessary power and reliability for a range of missions. The aircraft's composite fuselage construction also contributes to its lightweight and durability, further enhancing its operational efficiency and longevity.
The niche the MD 900 serves is primarily in EMS and law enforcement. Its ability to land in confined spaces, combined with its low noise footprint and high safety standards, makes it an ideal choice for medical evacuations and police operations in densely populated areas. Additionally, the helicopter's spacious cabin can be configured for various roles, from patient transport to tactical operations.
Market Position and Use Cases
Overall, the McDonnell Douglas MD 900 has earned a reputation for its advanced technology, versatility, and reliability. It continues to be a preferred choice in sectors where safety, performance, and operational flexibility are paramount, thereby underscoring its legacy in the realm of general aviation helicopters.
