“…In an effort to reduce the size of the combinatorial space, previous studies on subsystem architectures [7,12] considered subsystem electrification bundles or packages using reasoning based on rules with regard to a natural electrification ordering due to technology maturation status. For instance, the predefined strategy for Actuation Function Packages (AFPs) included the Primary Flight Control Actuators (PFCA, that include elevators, ailerons, and rudder), Trimmable Horizontal Stabilizer Actuation (THSA), Spoiler Actuation (SPLA), leading and trailing edge High Lift Device Actuation (HLDA), Nose Wheel Steering System (NWSS), Landing Gear Actuation System (LGAS), Wheel Brake System (WBS), and Thrust Reverser Actuation System (TRAS).…”
