Stability and Control of Helicopters in Steep Approaches. Volume 3. Derivatives and Transfer Functions for the YHC-1A Tandem-Rotor Helicopter and the S-58 Single-Rotor Helicopter

Abstract

Derivatives and transfer functions are presented for the Boeing- Vertol YHC-1A tandem-rotor helicopter and for the Sikorsky S-58 single-rotor helicopter. The flight conditions considered for the YHC-1A include forward speeds from 0 to 80 knots and descent rates from 0 to 25 fps. For the S-58 forward speeds of 0 to 100 knots and descent rates of 0 to 22.5 fps are considered.
