New Products

In this aerospace issue of Design News, we highlight the efforts of vendors who supply components to airframe designers. In truth, there's nothing new about this trend. Vendors have been supplying engines, pumps, motors, valves, wires, tubes, screws, bolts, rivets, and thousands of other products for as long as airplanes have existed.

But there is one new wrinkle in the supplier-OEM relationship, particularly in the area of fluid power. Today, airframe manufacturers are looking to fluid power vendors to supply more than components. Especially, in the business jet market, they want their vendors to design systems.

That's the case in Raytheon's new Hawker Horizon business jet. Raytheon engineers are working with Vickers Aerospace Div. of Eaton Corp. to supply the entire hydraulic power generation system, instead of just the pumps and motors.

As a result, Vickers engineers specify the filters, manifolds, reservoirs, pumps, valves, tubing, and dozens of other parts. They also lay out the components in the aircraft, claiming space just as an OEM engineer would. "They used to just give us a specfor instance a 32 gpm pumpand we never knew why they wanted 32 gpm," notes John Halet, director of engineering and research at Vickers' Jackson, MS, facility. "Now, we design the system and we determine the number, whether it's 32, 36, or 28 gpm."

For airframe manufacturers, the advantages are obvious. One of the biggest is so-called "risk sharing." Vendors share the upfront costs of developing new systems. They also share in support of the system for as long as 20 years after the product is sold.

There's also some less obvious advantages. Vendors can supply a team of on-site engineers, whose expertise is dedicated to a single type of system on the aircraft. And vendors can deal with subcontractors, a task that many OEM engineers don't relish. Vickers, for example, works with subcontractors who provide such parts as solenoids, filters, and manifolds.

That's a huge change for engineers involved in the vendor-OEM relationshipbut one that brings benefits for both sides. "We're doing things that we never did before, such as testing and flight certification," Halet says. "It's a whole new ball game for all of us."

Pinch valve

Our Fluid Power Pick-of-the-Issue isn't a fluid power item per se, since it's not truly a power item. But the patented new Flow Control Pinch Valve can serve in medical, pharmaceutical, food and beverage, chemical processing equipment, and scores of other applications that involve fluid movement. The innovative design may be the only one on the market that allows users to set the valve to a precise flow setting. To do so, you merely turn a knob. Because the valve includes graduated markings, users can select a setting and then duplicate that setting for all their other machinery. It works with all machines that employ soft-walled tubing.

Cost analysis software

Easier to use. More power. At a mid-range price. No, I'm not talking about a new CAD package. Analysis software, however, is going the way of CAD. COSMOS/WorksTM 5.0 design analysis, optimization, and simulation software embedded in SolidWorks 99 offers quite a few new features typically found in higher priced packages. AccuStressTM, a new transitional mesher, automatically detects small areas of geometry of potentially higher stress and places a tighter mesh or smaller elements at these positions, transitioning the mesh smoothly to the global size. Users have a complete low-cost simulation and optimization tool consisting of SolidWorks, COSMOS/Works, and Dynamic Designer/Motion. Motion loads from simulations performed within Dynamic Design/Motion can be automatically transferred to COSMOS/Works for analysis. In addition, V5.0 software analyzes assemblies with contact, friction and gaps.
