Aviation News – MD Helicopters has officially introduced the MD 564, a new light-single-engine aircraft designed to offer significantly enhanced payload capacity and hot-and-high performance. Derived from the iconic MD 500 series, this evolution aims to provide operators with superior lift and endurance capabilities without the need to transition to a larger, more expensive airframe class.
The MD 564 serves as a strategic performance upgrade to the legacy 500-series platform, focusing on versatility for utility, law enforcement, and military missions. By maintaining the familiar airframe footprint while upgrading the internal systems, the company provides a solution for customers requiring more power in demanding environments. This development comes as the global market sees increased demand for efficient, high-performance light helicopters capable of operating at high altitudes and in extreme temperatures.
The new model boasts impressive logistical improvements, including a 650-pound increase in internal payload and a 750-pound increase in external payload compared to previous generations. These upgrades allow for more significant mission equipment packages or increased transport capacity. Furthermore, the aircraft is designed for a four-hour endurance and a range exceeding 400 nautical miles, making it a formidable tool for long-range patrols and remote operations.
Technically, the MD 564 achieves its performance gains through a sophisticated six-blade main rotor system and a four-blade tail rotor, providing increased stability and lift. Powering the aircraft is the Rolls-Royce 250-C47E/3 engine, which features dual-channel FADEC (Full Authority Digital Engine Control). This digital control system optimizes engine efficiency, reduces pilot workload, and ensures reliable power delivery in the most challenging flight conditions.
