• Description:
  This report is a continuation of the studies described in Reference where a simplified approach to the problem of predicting the uncontrolled response of a single rotor helicopter to an encounter with the wing tip vortex of a large transport aircraft is presented. This investigation presents additional results assuming that the pilot of the helicopter responds to the motion of the heli­copter induced by the vortex encounter by applying control deflections. It is assumed that the pilot's response can be modeled as a simple feedback system. Control deflection proportional to helicopter attitude is assumed and only single loop closures are investigated.
