Flight Director Laws for the Longitudinal Cyclic and Collective Controls of the UH-1H Helicopter.

Abstract

A technique for determining flight director laws for the longitudinal control of a V/STOL aircraft in landing approach is evaluated. The method is based on the application of an optimal control model for the human pilot. The vehicle studied was the UH-1H helicopter at three approach groundspeeds: 60 knots, 40 knots, and 20 knots. The two pilot outputs were longitudinal cyclic and collective. In the analysis, ten pilot 'transfer functions' which relate the two control variables to the five displayed and perceived quantities were obtained. These transfer functions were then used to obtain the respective flight director laws.
