Simplified Analysis of an Emergency Flare Maneuver

Abstract

This technical note describes a simplified study of the flare maneuver of a helicopter at the end of an autorotation descent. Energy methods and momentum theory were utilized for the analysis of the parameters involved in the flare maneuver. A simulation was run on the basis of the data available for a commercial helicopter. The results are discussed, and a series of parameters are defined for the performance analysis of the flare maneuver.
