electro-mechanical actuators for Landing Gear
electro-mechanical actuators for Landing Gear
(OP)
Has anyone been involved with, or know about using electromechanical actuators in aircraft landing gear systems. Are they as reliable as hydraulic ones? How does the cost and weight compare with hydraulics? Any advice would be much appreciated!
Thanks
Thanks

If my memory serves me right, Mooney Aircraft has used electromechanical actuators for years.
Pratt & Whitney would like to eliminate accessory gear boxes on small turbine engines and incorporate electrical power generation right on the main engine shaft. This will lead to more aircraft designs that would use electrics for gear and flap actuation.
Boeing's is looking at using electric actuators for the 787 as well.

Electric motors and mechanics are both reversible, so where is the problem ?

Boeing 787 will use EMA's
Boeing X-45 currently uses (only)EMA's.
They are gaining acceptance for certain applications.
For any new design, a cost, weight, reliability, maintainability comparison with hydraulics would be appropriate.
Redundancy can be provided by a variety of methods.
