Dynamic Rollover of Gyroplanes during Landing—Cause and Prevention

Abstract While new-generation gyroplanes are very stable during flight, the susceptibility to roll over briefly after touching down is still issue due incorrectly applied landing procedure. A tendency dynamically also known from helicopters but rarely airplanes. The main cause for rotary wing aircraft’s risk rollover rotor force which relevant down. triangular wheel system of a gyroplane in combination with high centre gravity another factor gyroplane’s landing. Typical situations provoking landings severe crosswind or taxiing at too ground speeds rotating rotor. Both related incorrect piloting techniques. In this paper, forces acting on were investigated understand physical principles. Analytical equations evaluated using data reference single-track model road vehicle dynamics. It appeared that steering oversensitivity may occur if pilot moves stick forward early Non-linear simulations validated confirmed these analyses. Design parameter studies conducted analyse impact susceptibility. Finally, study most unlikely applies correct technique, means pulling control back properly
