Thales starter-generator integrated on Hispano-Suiza's POA test rig

Colombes, April 11, 2006

The starter-generator produced by Thales has been installed on the Hispano-Suiza Aircraft Systems Validation Rig (ASVR) in Colombes, near Paris, as part of the European POA (Power Optimized Aircraft) demonstrator program for "more electric" aircraft.

During initial tests the starter-generator performed successfully, providing electrical power to the equipment currently installed on the ASVR, equal to a load of 120 kW. All partners involved in the construction of the ASVR attended this demonstration.

The Thales starter-generator comprises a starter-alternator and power converter, capable of delivering 150 kW of continuous power to a high-voltage DC network, and of starting an aircraft engine requiring maximum mechanical power of 180 kW. The Thales alternator, an oil-cooled, permanent magnet unit operating at a maximum speed of 15,000 rpm, could be integrated directly in the high-pressure section of a jet engine.

Hispano-Suiza's validation rig is a characterization test bench for onboard electrical networks, representing a new-generation aircraft configuration. It was designed from the ground up to integrate a dozen electrical subsystems and components from various European manufacturers*. The acceptance and integration tests for this equipment started in 2005.

With the installation of the Thales starter-generator on the Hispano-Suiza test rig, the final phase of testing can now begin. The results of this series of tests will be used to enhance the DC electrical network and better understand the impact of the new static converter loads. Initial results will be presented at the Technologies for Energy Optimized Aircraft Equipment Systems forum (TEOPS), to be held in Paris from June 28-30, 2006 (
