An Assessment of the Hover Performance of The XH-59A Advancing Blade Concept Demonstration Helicopter

Abstract

This report documents a study of the hovering characteristics of the XH-59A helicopter, which was built to demonstrate the feasibility of the Advancing Blade Concept (ABC). The study examined in- and out-of-ground hover characteristics, aircraft and rotor figures of merit, and hover performance at 10- and 20-foot wheel heights. The XH-59A's performance is also compared to the performances of other Army helicopters. This indicates that the XH-59A performs better than other helicopters, largely because it lacks a tail rotor.
