Thrust reverser systems help to enable shorter landing distances and reduce wear on the braking system by slowing down the aircraft after touch-down. The actuator extends to deploy the system and retracts to stow it. Arkwin’s proven designs are capable of >250,000 cycles with the application of high external loads. Our thrust reverser system actuators operate at pressures up to 5,000 psig and feature multiple integrated control features for filtration, flow and directional control.
The long life and repeatability of the Arkwin lock mechanism has been demonstrated through field history and laboratory testing. F-16 lock actuators mechanisms have been subjected to Highly Accelerated Life Testing for determining suitability in other applications. This included unlocking with loads in excess of rated design valves. No appreciable change in performance or wear was noted at the end of 130,000 cycles. Production designs have unlock loads up to 20,000 pounds and ultimate loads over 50,000 pounds. These designs maintain very low unlock differential pressure values without the use of sequencing even under high load conditions. Usage spans from the C-5 to the CH-53K and many aircraft in between including 777, F-16, B-2, F-35 and more.
Thrust Reverser Actuator Systems
Arkwin’s expert engineering team uses the latest design software to convert concepts into reality for a multitude of installations. Arkwin has designed and manufactured over 125 unique hydraulic actuator designs, incorporating numerous customer options to fit customer specifications. Engine manufacturers rely on Arkwin’s expertise in designing the right actuator to meet their strict design and performance requirements. Arkwin actuators can be found in some of the most successful engine application installations in aerospace, and we continue to refine and develop new technologies to meet the needs of engine manufacturers worldwide. We offer a multitude of integrated control options on all types of actuators.
Fuel Driven Actuators provide actuation force to direct engine control components and provide electrical feedback of vane position to the engine computer. Our stable of proven high reliability, low maintenance, and fire-resistant designs are capable of >250,000 cycles and operating pressures up to 2,250 psig. We offer multiple mounting options, linear position sensing transducers, 3”+ diameter bores, and 3.5”+ strokes with servo valve applications in master/slave configurations.
The Ram Air Turbine (RAT) actuators deploy the RAT in the rare case when an aircraft loses power. The RAT then works to supply power necessary to control and land the aircraft. Arkwin’s proven designs are capable of >250,000 cycles with the application of high external loads. Our RAT Actuators operate at pressures up to 5,000 psig and feature multiple integrated control features for filtration, flow, and directional control. We offer multiple mounting options, linear position sensing transducers, 3”+ diameter bores and 25”+ strokes. Arkwin advanced locking mechanisms can be constructed featuring multiple pawl configurations depending on the application requirements. Locks can be integrated with visual and electrical lock indication or position sensing. Arkwin designs unlock with loads up to 20,000 pounds and hold over 33,000 pounds in operation.
