Toulouse, France-based Microturbo is here exhibiting a mockup of its e-APU, a new-generation auxiliary power unit that is currently undergoing ground trials. According to company engineers, the first test results are showing “excellent overall dynamic behavior.”

The e-APU has been designed for in-the-works business jets with increased electric power needs. Since its first run last December 31, the e-APU has exceeded its nominal power. It also has completed tests for fuel control adaptation, thermal and dynamic behavior and some transient operations. Instrumentation measured about 100 test points. Analysis has confirmed that objectives have been met. A second turbomachine has now just been added to the tests.
