Accessory gearboxes are a complex application used to distribute power to hydraulic, pneumatic, electrical, lubrication and other flight systems. These products are verified for flow, pressure, contact patterns and cleanliness before shipment.

Accessory Gearboxes

The Accessory Gearbox produces Hydraulic and Electrical power. Other Engine accessories such as starters, generators, fuel pumps, hydraulic pumps, oil pumps, speed sensors, etc. are also driven by the AGB. The Transfer and Inlet Gearboxes work in conjunction to provide power to the engine.

The TP85‐8 Air Drive Unit (ADU), also referred to as a Pneumatic Drive Turbine assembly, provides supplementary hydraulic power for the hydraulic system of an aircraft experiencing high load conditions. The turbine assemblies will also provide emergency hydraulic power should the engine‐driven hydraulic pumps onboard the aircraft fail to operate. The TP85‐8 ADU is driven by bleed air from the aircraft engine and is controlled by a three‐position control switch in the cockpit.

Airframe mounted accessory drives (AMADs) — Every TRIUMPH Geared Solutions accessory drive is built to the highest standards of precision and reliability. The AMAD provides power for the aircraft’s hydraulic pumps, auxiliary fuel pumps and electrical generators. It also provides engine starting capability by transmitting power from auxiliary power units. Our AMADs incorporate carburized and ground gearing and, if the specification requires, AGMA Class 14 standards. Each drive is designed for high power density to minimize weight. Special features such as self-pressurizing lubrication systems assure proper operation at all altitudes within a given flight envelope. The AMADs also contain a disconnect feature which allows ground crews to disconnect the unit for maintenance and performance of electronic and hydraulic systems checks without the engine running.

Fuel flow transmitters measure the flow rate of fuel through the component. As more fuel is flowed, more torque is applied to a turbine assembly. This torque creates distance between two magnetic pick-off’s which in turn creates distance between the electrical signal generated. The electrical signal is interpreted by a computer and a fuel flow rate is calculated.
