Experimental investigation of wing rock phenomena for high aspect ratio wings
The wing rock phenomena involves complex, multiple degrees of freedom non-linear dynamics, which results in the aircraft undergoing self-excited limit cycle oscillations (LCO) primarily in the roll axis. Wing rock is an undesirable motion which can occur at relatively low flight speeds when the airc...

| Summary: | The wing rock phenomena involves complex, multiple degrees of freedom non-linear dynamics, which results in the aircraft undergoing self-excited limit cycle oscillations (LCO) primarily in the roll axis. Wing rock is an undesirable motion which can occur at relatively low flight speeds when the aircraft is flying at high angles of attack. Although this effect has been extensively studied on slender delta wings, very little is understood about the sustained rotary motion of high aspect ratio rectangular (HARR) wings. With recent attention on the development of small unmanned aerial vehicles and micro aerial vehicles, where their operational flight envelope and atmospheric gust makes them susceptible to wing rock, it is highly relevant to further study the wing rock phenomenon on rectangular wings. |
