The average altitude for a helicopter is around 12,000 to 15,000 feet. This average is generally considered a safe altitude range for a helicopter to be flying in, and it’s one of many things a pilot must keep in mind when flying to avoid endangering either themselves or others. Likewise, there are many things any helicopter owner must do in order to keep their machine running smoothly and safely. Among these is looking after the hydraulic systems on any helicopter they own, including testing and required general maintenance. Below, we’ll quickly go over the hydraulics systems on a UH-60 Blackhawk, as well as why their maintenance is so important. But first, let’s get a better grasp of what we’re talking about here.
What Are Hydraulics?
Hydraulic systems are used in a variety of machines to produce different results. Hydraulics operate through the force of liquid pressure as it’s forced through the system of tubes, in contrast to pneumatics, which employs gasses for similar purposes. In terms of helicopters like the UH-60 Blackhawk, hydraulics and flight control are closely linked.
Why Are Hydraulic Systems Needed?
Hydraulic systems plan an integral role in the operations of a helicopter like the UH-60 Blackhawk. The UH-60 Blackhawk has a total of three hydraulic systems — two main hydraulics and one backup. The first hydraulic system supplies pressure to the first stage primary tail rotor servo and the first stage primary servos through the No. 1 transfer module.
The second hydraulic system provides pressure through the No. 2 transfer module, both to the second stage primary servos as well as to all pilot assist servos. The backup system supplies hydraulic pressure to the second stage tail rotor through the utility module and to all servos supplied by both systems through the No. 1 and No. 2 transfer modules.
Hydraulics on the UH-60 Blackhawk helicopter are the lifeblood of the machine. As a result, hydraulic testing should never be brushed aside. We perform UH-60 Blackhawk Hydraulic Testing for the 70106-08100-046 DAMPER ASSY. and support all MROs and overhead facilities for driveshafts and bifilar assembly. Don’t allow your Blackhawk to become damaged or dangerous due to improper maintenance. Ensure that all fuel and hydraulic lines are clear and able to function properly before flying.
