Electric Thrust Reverser Actuation Systems

All classes of airplane actuation systems have unique system level characteristics. This paper discusses key systems aspects of electric T/R actuation such as safety, power, controls, and maintainability, from an large airplane perspective, principally by comparing electric T/R actuation systems to equivalent hydraulic and pneumatic actuation. Enabling technology with which to implement system level requirements are discussed. The system issues are presented for a typical large airplane cascade T/R.
