- Dynamic_rollover abstract "A helicopter is susceptible to a lateral rolling tendency,called dynamic rollover, when lifting off the surface.For dynamic rollover to occur, some factor has to firstcause the helicopter to roll or pivot around a skid, orlanding gear wheel, until its critical rollover angle isreached. Then, beyond this point, main rotor thrust continuesthe roll and recovery is impossible. If the criticalrollover angle is exceeded, the helicopter rolls on itsside regardless of the cyclic control corrections made.Dynamic rollover begins when the helicopter starts topivot around its skid or wheel. This can occur for avariety of reasons, including the failure to remove atiedown or skid securing device, or if the skid or wheelcontacts a fixed object while hovering sideward, or ifthe gear is stuck in ice, soft asphalt, or mud. Dynamicrollover may also occur if the pilot does not use the properlanding or takeoff technique or while performing slopeoperations. Whatever the cause, if the gear or skidbecomes a pivot point, dynamic rollover is possible ifthe pilot does not use the proper corrective technique.Once started, dynamic rollover cannot be stopped byapplication of opposite cyclic control alone. For example, ifthe right skid contacts an object and becomes thepivot point while the helicopter starts rolling to theright, even with full left cyclic applied the main rotorthrust vector and its moment follows the aircraft as itcontinues rolling to the right. Quickly applying downcollective is the most effective way to stop dynamicrollover from developing. Dynamic rollover can occurin both skid and wheel equipped helicopters, and alltypes of rotor systems.".
