Aircraft hydrogen fuel cell specialist H3 Dynamics is teaming with XSun to develop what they describe as the world’s first solar-hydrogen-electric UAS.

Hydrogen-electric unveiling; hybrid-electric redesign; satcom antenna breakthrough; and immersion-cooled batteries.

Safran and Saft have entered a partnership to develop an 800V battery essentially aimed at future hybrid-electric aircraft.

GKN Aerospace is focusing on cryogenic cooling system and electrical network technology for hydrogen-fueled aircraft under the Airbus-led ICEFlight project.

GKN Aerospace's high-voltage wire harnesses have been delivered to RTX’s Collins Aerospace for testing on an experimental hybrid-electric PW1100G GTF.

Honeywell has completed the development of Surf-A, a new cockpit alerting system for runway incursions awareness, and expects certification by the end of this year.

CFM is increasing the pace and breadth of testing for its RISE advanced propulsion technology program with preparations underway with Airbus for subscale aircraft performance wind tunnel tests.

An open-fan engine would be less efficient than a more conventional ducted turbofan on a future narrowbody aircraft, says RTX Chief Scientist Michael Winter.
