High Speed Dynamometers

High-Speed Dynamometers for Aerospace and Gas Turbine Engines

The Froude HS range of Aerospace and Gas Turbine Engine Test Equipment has been developed over the years to meet the needs of testing new engines in R&D facilities. These state-of-the-art products are utilized in subsequent production facilities and the engine overhaul sector.

The high speed dynamometers are fitted with two half couplings which, with the rotor, are oil injected onto the shaft. High speed machines have oil mist lubricated bearings.

The dynamometer working compartment consists of special semi-circular shaped vanes cast into stainless steel rotor and stators. Water flowing in a toroidal vortex pattern around these vanes creates a torque reaction through the dynamometer casing which is resisted and measured by a precision load cell. The dynamometer load is controlled by a 'characterized' water outlet valve, operated by a closed loop electro-hydraulic servo system. The power absorbed by the dynamometer is carried away by the water in the form of heat.

We have Froude high-speed dynamometer solutions that could fulfill your test requirements. Contact us to learn about Froude's alternative solutions for smooth disc dynamometers.
