A system and associated method for achieving both force and position control of motor-driven electrical brake actuators for a brake disc stack that has, and seeks to maintain, a characteristic built-in clearance among the discs. The system employs both force feedback and motor turns position feedback associated with the actuator during a braking operation in order to obtain a motor turns position that achieves the characteristic built-in clearance following braking action or the like.

Force and position control of electrical brake actuators

Apparatus for aircraft brake thermal management including heat shields made of one or more insulating pouches of metallic foil having ceramic fibers or other appropriate insulation therein. The pouches are either vacuum sealed or provided with pin hole breathing apertures to eliminate expansion forces, while precluding the entry of cleaning fluids, moisture and the like into the cavity thereof. The invention further provides for brake rotor and stator disks having lugs of increased shear strength, while providing cooling apertures or slots therein. Finally, the invention includes a heat shield interposed between an aircraft wheel and the brake disk stack, and wherein the heat shield is flared at an end thereof to maximize the ingress and egress of cooling air to optimize aircraft turnaround time.
