A Two-Phase Investigation of Longitudinal Flying Qualities for Fighters. Phase I: The Effect of Evaluation Technique and Flight Phase on Flying Qualities Assessment. Phase II: An Example of Criteria Development, Control System Design and Flight Test Evaluation of Four Control Systems Using Eta-z, Alpha, and q Feedback.
Abstract
A two-phase study was performed using the USAF NT-33A variable stability airplane. In Phase I of the study the effect of the evaluation technique used in the assessment of airplane flying qualities for the air combat flight phase was investigated. In-flight evaluations with and without a target airplane were performed for selected configurations from AFFDL-TR-70-74. The results from the evaluations with a target airplane were compared to results obtained with a target airplane and to the results in AFFDL-TR-70-74. In all cases, the evaluations performed without a target airplane were adequate to reveal potential flying qualities problems in the detailed pilot comments. There was, however, larger variability in the rating differences between the evaluations performed with and without a target. There were also significant rating differences between the evaluations performed with and without a target for about 15% of the configurations.
