Case Studies

A tier-1 flight controls company was designing an innovative system for a new large commercial aircraft and required a hydraulic reservoir. EHA guidelines require that these reservoirs be 100% maintenance free.

Our customer, a large commercial airframer, challenged themselves to produce a next-generation aircraft concept that would deliver significantly lower total life cycle costs—including dramatically reduced-maintenance requirements.

Our customer—a large gas turbine manufacturer—required an automatic thermal valve that would actuate at temperatures exceeding 650°F. At the time, no existing thermal actuator technology could meet this specification.

Our customer, an agile and prestigious business jet manufacturer, was developing a new aircraft for a premium market segment. They were seeking a suite of lightweight hydraulic accumulators that would provide the lowest total life cycle cost possible.

A large commercial aircraft engine manufacturer needed a fire safety relief valve to automatically drain hydraulic fluid from their gearbox should the temperature in the gearbox approach the flash point of the hydraulic fluid.

The legacy design for a thermal actuator relied upon an elastomer-encased wax medium. Unfortunately operating temperature extremes rapidly degraded the elastomer, resulting in a very high rate of failure for this device.
