Hybrid Electric Propulsion
http://www.airframer.com/news_story.html?release=69689
Tests were successfully carried across three system
configurations: - Series Hybrid: In this configuration, the engine operates as a turbo-generator
that charges an on-board battery system, and does not contribute to thrust
directly. All power required for thrust and other onboard systems is supplied by
the battery. - Parallel Hybrid: In this configuration, the platform thrust is supplied by a
combination of the engine (mechanical thrust) and the electrical system
(electrical thrust), while the other power needs of the aircraft are met by the
battery. - Turbo-Electric mode: In this configuration, the battery system is redundant.
The engine operates as a pure turbo-generator supplying electric power for
thrust and any other power needs on the aircraft. The next step is to further
advance the hybrid propulsion system towards integration on an aircraft and
experimental flights in 2021. The M250 hybrid power pack complements the AE 2100
2.5MW system being developed for larger aircraft, including regional aviation,
and is being tested with Airbus on the E-Fan X demonstrator platform.
