An optical pressure measurement system for control inceptors to evaluate pilots’ workload

چکیده

Understanding human-machine interaction is a fundamental research area in all engineering disciplines were the between user and vehicle central. From this point of view, aircraft general helicopters specifically offer challenging test-bench: pilot helicopter crucial tothe success flight missions. Furthermore, some cases, unwanted feedthrough accelerations at control inputs can lead to adverse feedback loops, known as Rotorcraft Pilot Couplings (RPC) [1,2]. Since input mediated by inceptors, measuring pressure that pilot’s hands exert on inceptors’ grip be very important evaluating mechanical impedance pilot, which correlated task workload [3]. However, Embedding existing measurement hardware inside inceptors grips may challenging, or even impossible, without significantly altering layout thus introducing possible source discomfort for pilot. These limits spurred need develop new systems, able - provide reliable signal force exchanged hand grip; easy manufactured such way embedded grip, with little loss ergonomics possible; requires conditioning possible.The solution proposed work has been called OPT-IN FCS (For OPTical-INceptors Flight Control System, Patent Pending) based well-known physical phenomenon commonly referred Frustrated Total Internal Reflection (FTIR). When an optical wave-guide, total internal reflection occurs, comes into contact third medium (outside wave-guide itself air) fraction incident radiation propagate through medium. The paper will present design manufacturing full prototype device stick, its application desktop simulator monitor activity pilots during performance tasks different levels workload.[1] M.D. Pavel, M.
