AEROSPACE AND TURBINE TEST EQUIPMENT




testingindonesia.com
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.









SPESIFIKASI

Description

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.

Main Features:
  • High speed, up to 30,000 RPM
  • Speed measurement accuracy ±1 RPM
  • Torque measurement accuracy ±0.25% of full rated torque of dynamometer
  • Servo load control
  • Rapid response
  • Stable operation
  • High reliability
  • Tandem Machines Available
  • Bi-directional Configurations available with the use of a turntable

testingindonesia.com The Froude F Range Hydraulic dynamometers (also referred to as water brakes) have been designed to be compact, robust and to allow easy maintenance. Some of these models are available with a streamlined, fabricated base. This base is not only ultra durable due to the powder coating process, but also offers flexibility with water inlet/outlet placement and lifting eye locations. These engine dynos are fitted with two half couplings which, with the rotor, are oil injected onto the shaft. The standard machines run in grease lubricated rolling element bearings. The hydraulic 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 'butterfly' water outlet valve, oper

The Froude AC dynamometer has been specifically designed for the testing of gasoline and diesel engines in R & D and Quality Audit applications.   Low inertia AC motor with standard speed ranges from 3,500 rpm to 10,000 rpm Standard torque hub measurement accuracy is +/-0.2% of the full rated torque of the dynamometer Speed is measured to an accuracy of +/- 1 rpm testingindonesia.com      SPESIFIKASI       Description The AC dynamometer is constructed using a low inertia AC motor especially designed for engine test applications mounted on a substantial fabricated baseframe. On foot mounted versions torque is measured using an in-line torque hub. For trunnion mounted machines a precision strain gauge load cell is used. As an option both versions can include an integrated jackshaft that provides additional overhung load capacity for the engine drive shaft.                 Froude AC       Dynamometer Heat gen

EDDY CURRENT ENGINE DYNAMOMETERS

Overview testingindonesia.com SuperFlow offers a broad selection of technologically advanced eddy current absorbers which are ideal for precise engine testing. Low minimum load capabilities allow testing of very small engines, or larger engines running at very light loads and high speeds. Heat is dissipated by cooling water flowing through the stationary portion of the absorber. Rotating water seals have been eliminated. Bearings are pre-lubricated and rated for 5,000 hours of operation between servicing. Standard commercial load cells measure reaction torque for either direction of rotation. The double-ended main shaft may be fitted with a starter motor or used for dual engine connection. Speed is measured by a 60-tooth gear and hall effect sensor. All SuperFlow dry gap eddy current absorbers can be interfaced with SuperFlow data acquisition and control systems for complete engine, dynamometer and throttle control. These systems integrate with personal computers running Supe
