A carbon nanotube surface film replaces metal mesh to dissipate lightning energy on composite aircraft parts with lower weight and less microcracking.
Dual power signal lines and independent switches keep remote brake engagement working when ECU-controlled solenoids fail.
Adjustable torque limiting lets an EMA permit droop movement after power loss while reducing stop damage and spurious extension.
Adaptive torque limiting in an EMA lowers stop-zone loads and releases anti-extension when needed to protect the actuator and allow spoiler movement.
