UH-60 Black Hawk庐 Military Global Sustainment
Pitch Trim Actuation
The UH-60 utilizes a Moog, Pitch Trim Actuator as part of the overall helicopter flight controls.听 A Pilot鈥檚 force input at the stick听is mechanically transferred to the input linkage of the Pitch Trim听Actuator. The input linkage is connected to the output linkage听through the Boost Actuator, which multiplies the pilot鈥檚 input force.听 Movements at the output linkages are mechanically transferred to the main听rotor of the aircraft. Trim functionality is controlled by the Pilot鈥檚 signal input,听which will command either the Pitch Trim Actuator to hold a specific听position, therefore trimming the main rotor in the corresponding direction.
Vibration Control Actuation System
The UH-60 utilizes our Vibration Control Actuation System (VCAS).听This system replaces traditional passive systems by measuring vibration levels听at key locations in the aircraft and applying cancellation forces in an equal听and opposite direction. The VCAS system adjusts these forces as the aircraft听maneuvers and as payloads change thereby increasing overall efficiency.听This also results in reducing airframe fatigue, pilot fatigue and overall听maintenance costs.
Self-Displacing Accumulator
The SDA (self-displacing accumulator) provides hydraulic pressure听to the APU (auxiliary power unit) motor used to start the two engines. It听consists of high-pressure hydraulic fluid and dry nitrogen chambers separated听by a piston, and a low-pressure hydraulic fluid chamber (reservoir) containing a听second piston connected to the first piston. A mechanical tape attached to the听piston rod indicates high-pressure chamber volume from 0 (discharged) to 100%听(fully charged). After motor start the hydraulic fluid is circulated, or returned听back to the reservoir (self-displacement).听

ADAHRS Only Upgrade
Replaces the legacy attitude source that poses reliability, obsolescense, and cost challenges for operators. An ADAHRS upgrade provide the necessary听interace that drives the stability augmentation system and existing panel听attitude indicators. This upgrade is a standalone solution for aircraft,听replacing and modernizing legacy equipment without the requirement to upgrade to a full avionics suite.
