Study of the Feasibility of Conducting a Wake-Riding Experiment Using a T-2 Aircraft Behind Two P-3 Aircraft

Abstract

A study has been made of a T-2 aircraft attempting to establish a wake-riding position behind two P-3 aircraft. The major objectives were to estimate structural loads in the wake rider and to evaluate wake entry and station keeping control techniques. The results of the study indicate that the root-bending load on the tail of the T-2 aircraft would be of the order of the design load if the aircraft were to inadvertently pass directly through the center of a trailing vortex from one of the P-3's. Thus the flight tests, as originally envisaged, must be considered as high risk experiments unless the tail of the T-2 were to be strengthened. If wake riding experiments are carried out, approach to the wake-riding position should be made from above using a reduced-power, constant-airspeed approach. In calm air the piloting task appears reasonable if the trailing vortices are marked by smoke or condensation.
