F-35 Lead System Integrator

Moog is leading an industry team in the development, integration and qualification of the Primary Flight Control and Leading

Edge Flap Actuation Systems for all three variants of the F-35 Joint Strike Fighter. As the prime contract holder, Moog’s role

includes management of the industry teams, integration of the complete actuation systems, and key supplier of critical

technologies and major subsystems. Moog is also the OEM supplier of the Lift System Primary Actuation for the

F-35B STOVL variant and the Wingfold Actuation Systems on the F-35C carrier variant.

Primary Flight Control Actuation System Overview

The F-35 Primary Flight Control Actuation System features a “power-by-wire” architecture with fully self-contained

electrohydrostatic actuators (EHA) positioning the primary flight surface (horizontal tails, flaperons and rudders). Each primary

flight surface is controlled by one EHA. The EHAs for the horizontal tail and flaperon are dual tandem whereas the rudder

configuration is simplex. The electronics control unit (ECU) includes loop closure control electronics (CE) and motor-pump

power drive electronics (PDE) to position the EHA. The ECU includes the hardware and software required to perform the

control, monitoring, redundancy management and built-in test (BIT).

Leading Edge Flap Actuation System Overview

The Leading Edge Flap Actuation System (LEFAS) includes all hardware and software necessary to position the leading edge flaps

in response to position commands issued from the vehicle management computer (VMC). The LEFAS also monitors performance

and position of the flaps and reports back to the VMC. On each wing, Moog provides an electronic control unit, electronic power

drive unit, asymmetry brake and outboard position sensor. For the C variant, Moog also provides the foldbox assembly.

Lift System Primary Actuation OverviewThe hovering ability of the F-35B STOVL aircraft is provided by the lift system, which combines a thrust vectoring nozzle that directs main engine exhaust downward to generate aft vertical lift and a centrally mounted lift fan to counterbalance forward vertical lift. Moog supplies the Lift System Primary Actuation, which includes the actuation system for the three-bearing swivel nozzle and the actuation system for the lift fan’s variable area nozzle and inlet guide vane. These actuation systems use electronically controlled hydraulic and fueldraulic servoactuators specially designed for operation in extreme temperature and vibration environments.

Wingfold Actuation System Overview

The Wingfold Actuation system converts electric power into rotary motion to fold and spread the wing tip in response to electrical

commands issued from the controller. The power drive unit receives electrical power through the controller and an AC motor

converts the electrical power into rotary motion. The output of the electric motor provides the torque and speed output required

to drive two locking transmissions that either fold or spread the outer wing accordingly.
