An Adaptive In-Flight Load Distribution Control Using Pressure Field Sensing

Mori, Ryota / Maki, Midori / Tamayama, Masato

Multidisciplinary optimization in aircraft design is approaching its limits, and breakthrough technologies are needed to improve further fuel efficiency. If in-flight switching control can be feasible between a drag-minimizing load distribution during a cruise, which accounts for most of the flight time, and a dedicated gust-tolerant load distribution for turbulent airspace, then it will be possible to extend the aspect ratio of the main wing while mitigating actual structural damage without weight increase. The technology to design the optimum target load distribution by multi-objective optimization already exists, but the feasibility of feedback control to realize the target load distribution has not yet been investigated. In this study, this problem is solved by an adaption scheme consisting of in-flight pressure field sensing, real-time modeling of unsteady pressure fluctuations, and stochastic optimal control. The effectiveness of the proposed active technology will be shown through wind tunnel testing.
