The proposed DIRECT system is consistent with the main objectives of the NASA N+3 Concept Aircraft Project. In particular, it addresses the problem of flutter identification and suppression, while simultaneously achieving drag reduction using performance-seeking control algorithm. Hence the proposed DIRECT system can be used in future designs of HALE UAVs with flexible wings. The use of the DIRECT technology in this context would help in lowering the costs of NASA scientific research by reducing fuel consumption, and in contributing to environmental protection by lowering emissions and noise.
The proposed DIRECT system is applicable to future flexible-wing commercial vehicle concepts where the main objective is to enhance fuel efficiency while reducing noise and emissions. The approach will also be applicable to military aircraft with elastic wings.
