The dynamics of elastic systems coupled with rotating bladed-rotors is rich and complex,
and the blade number may have an influence on the in-vacuo system dynamics. This paper …

This work is motivated by the rapid developments of a broad range of electrically powered
vertical take-off and landing vehicles which frequently feature two-bladed thrust generating …

In helicopter with hinged rotor, an unstable dynamic phenomenon known as ground
resonance may occur, leading to the total destruction of the aircraft. The prediction of the …
