Growth Prospects of Global Aircraft Hydraulic System Market During 2017 – 2025

Global Aircraft Hydraulic System Market: Introduction

Factors such as rise in global air travel and surge in new aircraft deliveries in countries such as China, Mexico, Brazil and India are estimated to be the key growth drivers in the global aircraft hydraulic system market.

Hydraulic systems have experienced a major transformation in terms of weight (they have become lighter over the years), simplification of inspection, ease of installation and maintenance requirements (latest hydraulic systems demand minimum maintenance). Hydraulic systems are not new to the aircraft market. In the past, aircrafts have used hydraulic brake systems. As the aircraft industry is evolving, manufacturers are coming up with newer systems. Hydraulic power systems were developed to meet the requirements of the modern-day aircraft industry.

Aircraft hydraulic systems enhance the efficiency of an aircraft’s components. Aircraft hydraulic systems facilitate easy operation of flaps, landing gear, brakes and flight control surfaces in aircrafts. The complexity of aircraft hydraulic systems depends on the size of the aircraft. For instance, smaller size aircrafts need hydraulic fluid only for wheel brakes. Larger size commercial aircrafts, on the other hand, require hydraulic systems that are complex and large in size. To achieve the essential consistency, an aircraft hydraulic system may consist of several subsystems. Each subsystem include actuators & filters, reservoir, pump, vane & spur gear, hydraulic fluid, pressure regulator, accumulator, valves and others (connectors).

Hydraulics and the Tangent Bender 

The Tangent Bender is a basic production machine designed to bend sheet metal and to form rounded corners in a single operation. This is accomplished by wrapping a ram-type rocker plate die around a radius forming die against which the stock to be formed is clamped. The power arm of the machine is a swinging wing assembly to which the rocker plate is attached by a rack and pinion. In the loading position the rocker plate is horizontal and acts as a female die directly or as a base platen for the die fixture.

A heavy spring on the outer half of the power arm is adjustable and fits against a bearing block supporting the pressure roll. The rear end of the power cylinder is anchored on a clevis mount against the rear base of the machine, the front end is similarly mounted on a projection of the bearing block housing at the approximate center of the power arm.

The Tangent Bender was first—and still is—widely used for forming shells of refrigerator cabinets. Other production uses include washing machines, electric stoves, space heaters, vending machines, tubular chair frames, camera and small-appliance bodies. When originally introduced, the machines were air-cylinder operated. These units did—and still do—credible work. However, they had some limitations that were troublesome on some classes of work.

Production Difficulties
The application of hydraulic power to the machine was the result of an effort to find a power source that would correct and compensate for the commonly encountered production difficulties. The first difficulty was the interruption in production due to uneven power flow. The second problem arose from the need for greater power to form heavier sheets. A third difficulty was due to the fact that variations in the thicknesses of commercial sheets required sorting and interruptions m production to adjust the machine.

On heavy-duty jobs, cylinders had a tendency to pause until the air pressure could build up sufficiently to overcome the resistance of the metal sheets. When pressure did build up, the cylinders jumped ahead, resulting in a wrinkling or “orange peel” effect on the finished work. These irregularities, when severe, caused rejection. The salvageable work required considerable hand finishing.

Volvo CE’s Fully-Electric Compact Excavator Prototype Wins Intermat Innovation Award 

Volvo Construction Equipment’s 100 percent electric compact excavator prototype — known as the EX2 — has won the prestigious Equipment & Machinery Award in the Earthmoving & Demolition category of the Intermat Innovation Awards. The concept machine, which delivers zero emissions, 10 times higher efficiency, 10 times lower noise levels and reduced total cost of ownership compared to its conventional counterparts, was recognized for its contribution towards progress in the construction industry. It is believed to be the world’s first fully-electric compact excavator prototype. At this stage, the EX2 is still part of a research project and it is not commercially available.

“I am extremely proud that the EX2 has been awarded this globally-recognized innovation award,” said Ahcène Nedjimi, electromobility specialist and EX2 project leader at Volvo CE.

“The EX2 is a revolutionary machine. The electrification of construction equipment will produce cleaner, quieter and more efficient machines — this represents the future of our industry. I’m pleased that the judges have recognized its significance.”

The Technology Behind the Concept

To make the EX2 prototype fully electric, the combustion engine has been replaced with two lithium ion batteries, totaling 38KWh, which store enough electric energy to operate the machine for eight hours in an intense application, such as digging compact ground. The hydraulic architecture also has been replaced with electric architecture, which incorporates electromechanical linear actuators that help to optimize the transmission chain. Removing the hydraulic system and the combustion engine, as well as reducing the cooling needs, has led to significantly lower noise levels.

“With its zero emissions and ten times lower noise levels, the EX2 could easily be used in densely populated areas without disturbing people — even at night,” said Ahcène. “Ten times higher machine efficiency, together with maintenance-free systems, means that operating costs and total cost of ownership would be significantly reduced.

“And because the EX2 is fully electrified and there are no mechanical joysticks, it can be controlled remotely from a mobile phone or tablet. This increases safety in hazardous working environments. Additionally, the EX2 delivers the same power and force as its conventional counterpart, as well as faster speeds in combined movements. As this type of movement is the most common kind for this machine, productivity is improved.

“All of this has been achieved without compromising on machine performance, ensuring customer needs would be fulfilled.”

Innovating for Progress

The Intermat 2018 Innovation Awards honor equipment, techniques, services, products and solutions that contribute towards progress in the construction and infrastructure industry. The jury, under the chairmanship of the president of the French National Federation of Public Works (FNTP), announced its decision at an award ceremony on Jan. 18 in Paris. The judging panel consisted of 13 industry specialists who selected the top nine submissions to receive awards out of a field of 90 entries from leading manufacturers.

“The EX2 forms part of Volvo CE’s long-term ambition of achieving sustainable transport solutions,” said Patrik Lundblad, senior vice president of Volvo CE’s Technology function. “This award is a tribute to the hard work and vision of Volvo CE’s employees, who continue to push the boundaries of technology and innovation and ensure the company is at the forefront of technological development. We are now looking forward to presenting the EX2 prototype at Intermat in April.”

CATERPILLAR AND SANMAR DEVELOP HYDRAULIC HYBRID SYSTEM 

Caterpillar Marine and Sanmar Shipyards have entered into a collaboration agreement to build a tug with an innovative hydraulic propulsion system furthering principle of a hybrid tug design.

Seldom a month passes where news related to alternative-fuelled or so-called green tugs is not reported here. Despite something of a hiatus which some suggest is related to a period of low conventional fuel prices it is clear this latest revolution, particularly with shiphandling and escort tugs continues to develop.

Owners are attracted by the various benefits associated with green tugs including increased fuel efficiencies and subsequent reductions in running costs, not to mention pressure to improve the environmental footprint of what by the nature of the job can be a somewhat ‘smokey’ activity. The bottom line of course is the cost of the investment or put another way the pay-back time and this alternative to the more normal hybrid arrangement involving electric motors and batteries presents an interesting development.

The new and patented Marine Advanced Variable Drive (AVD) harnesses Caterpillar’s experience with integrated power systems along with Sanmar’s expanding tug building business and involves a fully integrated hydro-mechanical propulsion system which it is claimed, provides ‘significant improvements’ in both fuel efficiency and vessel performance.

Caterpillar state that different from a typical power take-in solution, the AVD incorporates a planetary gear set allowing seamless clutch engagement of main engines, auxiliary engines, or both to provide a scalable power installation to meet operational needs in terms of maximum vessel speed, power, or bollard pull. This also allows propeller speed independent of engine speed with optimal engine efficiency leading to fuel savings of fifteen to twenty percent, essentially all the benefits of a variable speed diesel-electric propulsion system, Caterpillar claim at a fraction of the cost and size.

The AVD system’s flexibility can accommodate multiple configurations whereby auxiliary engines can be utilised to provide low load or transit operations extending the time between overhauls. Electric motors can be used instead of hydraulics if desired and diesel engines can be substituted by natural gas as the system provides superior vessel performance regardless of engine load acceptance. Main engines can also be downsized with supplemental power supplied via auxiliaries or generators if electric motors are used.

The vessel selected for the first Caterpillar AVD system will be a Robert Allan Ltd-designed RAmparts 2400SX tug. The machinery specification is unsurprisingly dominated by Caterpillar, centred on: two 3512 main engines, a C32 auxiliary and Cat MTA 627 fixed-pitch thrusters. The AVD system will include fully-integrated controls with customised operating modes and display panels in the wheelhouse. Compared to conventionally-powered examples with equivalent bollard pull (70t) the return on investment is estimated at three years or less based on projected fuel and operating cost savings.

Produce Better Hydraulic Components with Metal 3D Printing

Complex hydraulic components made via metal 3D printing can incorporate details that would be difficult or impossible to duplicate through conventional machining, and weight and size are reduced without compromising performance.

Hydraulic pumps, cylinders, and other actuators deliver greater power in smaller packages than engines, electric motors, and mechanical actuators. Hydraulic valves easily control direction, speed, torque, and force with anything from simple manual operation to sophisticated electronic controls.

Yet, production methods that create these hydraulic components have not kept pace with the expanding scope of their applications. Enter metal 3D printing—it offers new opportunities to capitalize on the high power density of hydraulic technology by improving the design and production of components such as manifolds, valve blocks, and valve spools.

Three-dimensional printing, which began as rapid prototyping, has progressed beyond its original plastic materials to encompass many metal alloys. Although not practical or cost-effective for high-volume production, 3D printing offers many advantages when producing metal hydraulic components in smaller quantities and special designs.

Without the limitations of conventional machining, parts can be designed for the most efficient combination of production and performance. And internal channels can be optimized for higher flow and lower pressure drop. It’s also possible to produce several different prototypes within hours to determine the best design. Furthermore, components can be made from a variety of materials, including stainless steel (from AISI 304 to AISI 316L), aluminum, titanium, and new materials still under development. Sources of potential leakage from auxiliary drilling and subsequent plugging are eliminated.

Although hydraulic components can be produced either by traditional manufacturing or 3D printing, traditional manufacturing is a subtractive process that starts with a larger piece of material, usually a metal casting or bar. Material is removed, generally by CNC machining, to leave the desired shape. Excess material often is left in place to save the expense of removing it, resulting in parts that weigh more than necessary.

Machining also is limited in its ability to produce many desired configurations. Passageways in conventional manifolds often must be positioned to prevent cross-drilled channels from intersecting and allow enough material between channels to provide adequate strength. Auxiliary holes drilled to connect internal passageways may need to be plugged, creating the potential for a future leak.

Three-dimensional printing, by contrast, is a form of additive manufacturing, which builds up the desired part layer by layer. With 3D printing, flow channels can be placed exactly where they are needed, and in optimum size and shape. Until now, flow channels, particularly in components such as valve spools, generally have been circular because they are machined with rotating cutters. By building a component in layers, designers can specify configurations that would be difficult or impossible using conventional manufacturing methods.

Keestrack’s focus on electrification 

In its drive to reduce costs through the electrification of its track-mounted processing units, Keestrack is concentrating on hybrid crushing technology.

Following fully hybrid H4 cone crushers and B4e jaw crushers, the company is now introducing the R5e hybrid impact crusher unit, designed to guarantee full capacity at low consumption costs with the aid of a directly driven 350 tonne per hour crusher and electrical transport and screen components.

Keestrack’s track-mounted impact crusher units include three models, starting with the compact R3, a flexible 30 tonne “construction-site crusher.”

Keestrack’s R6 flagship model has a total weight of 60 tonnes when fully equipped and remains a prominent machine among the 1300-impactors for recycling, large-scale projects and quarrying applications.

Thanks to the licence-exempt dolly transport, it readily competes with the much heavier competition within the 450 tonne per hour performance class. As well, the large-scale “Destroyer” unit has been available for several years as an R6e model in a diesel-electric hybrid version with electric motors driving the conveyor belts and screen components.

Since 2014, the Keestrack R6e has been available with a 250-kW electric motor for the crusher and an electric 110 kW drive for the on-board hydraulic system, and an optional all-electric plug-in operation from the mains. Equipped with a high-performance, on-board diesel engine, the large-scale crushers remain flexible, while up to 45 per cent of the energy costs can be saved, even in semi-stationary operations.

Proof in Keestrack numbers
The advantage is reflected in Keestrack’s sales. In 2016, 80 per cent of the R6 machines sold were represented by diesel-electric or all-electric sales. This year, the total number of units sold in 2016 was reached before the end of the first six months — 90 per cent of these being in the form of hybrid or fully hybrid models.

The Keestrack R5 is a mid-range series of models with an about 42 tonne basic weight and a maximum 50 tonnes with an overband magnet and double-deck final screen, including oversize material recycler.

When it was introduced more than three years ago, the mobility and production rate of the diesel-hydraulic crusher proved to be virtually unrivalled for its performance class, according to Keestrack. Now following a series of upgrades, Keestrack presents the R5e, a diesel-electric version of its 350 tonne per hour all-round model.

Avoiding Problems with Hydraulic Cylinders 

The term “high pressure” in hydraulics is quite subjective. Among the strictest definitions is any system with operating pressure exceeding 10,000 psi. Perhaps a more general interpretation is 6,000 psi, which will be assumed for this discussion. For this article, high system pressure will be defined as 6,000 psi (410 bar). This is the pressure setting on some newer excavator functions. A system that operates at 6,000 psi will see brief pressure spikes that are two to three times the 6,000-psi working pressure. This means the components need to accommodate 12,000 to 18,000 psi, 827 to 1,241 bar pressure spikes, for a reasonable service life of 8,000 hours (about four years), and should not fail in less than 2,000 hours, about one year of service.

Because most of my extensive learning experience is from working with logging and construction equipment attachments, the examples I have set forth are from those industries. I chose not to blame the customer for using the cylinders differently than I specified, and I accepted full warranty responsibility for any poor design choices. Several cylinders were repaired under warranty several times, and a few cylinders were scrapped and completely new designs implemented to meet the self-imposed one-year or 2,000-hour warranty.

The concepts and areas of focus being presented here can be applied to most hydraulic cylinder applications.

Cylinder Design Considerations

What is actually being done with the cylinder and how is the cylinder being loaded? When a machine or attachment is being designed, the designer has an idea of what the unit should do and how it should be done. As soon as you hand the machine to a different operator, the application, duty cycle, and operating parameters have changed. In some cases the change is enough that things start to fail. Frequently, the cylinder will be subjected to a work-induced load that is much greater than what is possible by direct control.

  • Will the cylinder need load-holding valves? Both counterbalance valves and pilot-operated check valves are used to hold a cylinder in position, and both valves can produce additional loads on the cylinder components when in operation. Some load-holding valve settings are increased by back pressure on the pilot port.
  • What is the cylinder stroke? A short-stroke cylinder does not typically need to be concerned with buckling load design. A long-stroke cylinder will require running a buckling load calculation. Use standard NFPA standard T3.6.37 R1-2010 for buckling calculations.
  • How fast is the cylinder going to move? The speed the cylinder will move, or the flow going into the cylinder, must be considered to determine port and plumbing size. This speed is also important when designing cushions if they are required.
  • What are the appropriate bore and rod diameters? Choosing the correct bore and rod size can be the single most difficult aspect of the cylinder to determine because of the forces required when extending and retracting, the stroke required, and the pin centers’ distance needed to be met. If the cylinder needs cushioning, this could change the bore or rod size requirements. Sometimes a larger bore and rod will be required to meet all the design needs. One side of the piston may need to run at a lower pressure to meet the force requirements as well as structural requirements, such as the piston-to-rod interface, the piston-fastening needs, and buckling of the rod.
