Coaxial Compound Helicopter for Confined Urban Operations

[hesham]

Hi,

A rotorcraft was designed for military operations in a confined urban environment. The specifications included major increases in useful load, range, and speed relative current aircraft capabilities, with a size constraint based on the dimensions of urban streets and intersections. Analysis showed that this combination of requirements is best satisfied by a coaxial main-rotor configuration, with lift compounding to off-load the rotors at high speed, and ducted fans under the rotor disk for propulsion. The baseline design is described, and the aircraft performance is summarized for utility, attack, MEDEVAC, and cargo delivery missions. The impact on size and performance is examined for a number of excursions, including lift-offset main rotors. Technology development required to achieve this advance in capability is recommended.

This is the work of the U.S. Army aerospace engineers who were tasked with investigating means to meet the JMR-TD Cap Set 1 requirements. This effort would support requirement refinement for what would become the FVL FARA effort. This effort was never intended to develop a flying helicopter.
