The company THALES AES studied under contract DGA and in collaboration with other companies, electric generation system capable of delivering a significant overhead for ten seconds. This source of electrical energy is designed to equip an electrically propelled combat vehicle.
Overloading represents an obstacle crossing. The generator drive engine is expected to deliver the continuous power while ten seconds surcharge is levied on the kinetic energy of the rotating parts of the group.
In order to store a large kinetic energy without increasing much mass, the generator speed is chosen as high as possible while being compatible with the mechanical constraints of the rotating parts. The rotating inertia issuing this transient kinetic energy should be sufficient so that the speed of rotation of the assembly does not drop during the transient below a speed equal to half the nominal speed.
This generator is a high-speed alternator demonstrator for aeronautical applications. This article describes the complete system chosen, the rotating inertia generator, Generator Control Unit (GCU) and the tests carried out on a generator model.
