Evaluation of Lateral-Directional Handling Qualities and Roll-Sideslip Coupling of Fighter Class Airplanes
Abstract
Maneuvering tasks representative of the fighter mission and a precision bank angle tracking task were performed for evaluations. Evaluations were conducted at three Dutch roll frequencies, three roll-to-sideslip ratios and at values of Dutch roll damping on either side of the MIL-F-8785B(ASG) boundary. Satisfactory flying qualities were not obtained for any of the low Dutch roll frequency configurations investigated in this experiment. The Dutch roll damping requirements were found to be adequate, especially when the additional increment of damping as a function of Dutch roll frequency and roll- to-sideslip ratio is added. The roll-sideslip coupling requirements in terms of sideslip excursions were found to be conservative, especially at low to moderate values of roll-to-sideslip ratio.
