Eaton has tested its first electronically synchronised flap drive mechanism for an aircraft. The system, designed and built specifically for the Embraer Phenom 100 very light jet, will reduce aircraft weight while increasing system performance and reliability, says Eaton.
The key to the new flap drivers is distributed electronically synchronised, brushless DC motors integrated directly into each flap actuator. Traditional mechanical flap systems for aircraft have flexible metal shafts connected between each flap, or slat actuators mounted in the aircraft wing and powered by a central power drive unit. In this case, system synchronisation is accomplished electronically, replacing the flex shafts with electrical wiring.
Eaton reports a weight saving of 25% over the traditional mechanical system. Development testing for the flap actuation system will continue throughout December, with safety-of-flight testing on an "iron bird" aircraft simulator at the company's Grand Rapids, Michigan base next month.
Embraer has selected Goodrich to provide an air data system for the Phenom 300 business jet. The award is expected to generate $20 million in original equipment and aftermarket revenues for Goodrich during the programme.
