Linear flight-control actuation systems

The Flight control actuators is a linear flight-control actuation system from Moog with aerospace-grade grade and dual-use market. Moog flight control actuators are linear and rotary flight-control actuation systems for aircraft, offered by Moog as part of its aircraft actuation portfolio. The range covers actuation for primary flight controls, secondary flight controls, maneuvering leading edge and high-lift control, with linear actuation used inside these wider systems to move control surfaces and high-lift devices.

Moog approaches each application as a technology-neutral supplier, so the actuation technology is selected for the aircraft and not imposed: electrohydraulic, electrohydrostatic and electromechanical solutions are all offered for secondary flight control. This lets an airframer or system integrator compare the options in a trade study around weight, reliability, performance and cost.

For primary flight controls the maker offers customized fly-by-wire or full power-by-wire solutions in simplex, dual, triplex and quad redundant designs. The redundancy level is the main design choice here, since it sets how many independent channels drive each surface and how the system reacts to a failure. For maneuvering leading edge applications the maker supplies high-reliability geared mechanical systems for high-performance aircraft.

High-lift control covers complete leading and trailing edge solutions, including power drives, geared rotary or linear mechanical actuation, interconnects and accessories. The platform class given for this product is manned aircraft, and the maker states that its actuation is installed on nearly every aircraft type in the market.

Related Moog products on the same site are engine controls, flight control computers and controllers, controls and software, which are the elements normally integrated with the actuators in a flight control system. A buyer or integrator selects the actuation type, the number of redundant channels and the surface or high-lift function to be driven, and then works with the maker on the installation for the specific aircraft.
