Latecoere and its subsidiary company Comtek Advanced Structures have been selected by leading engine manufacturer Pratt & Whitney Canada to design and build a major structural assembly for the RTX Hybrid-Electric Flight Demonstrator program. Pratt & Whitney Canada is leading a cross-industry collaboration to develop hybrid-electric propulsion technology which aims to support the industry's goal of net-zero CO2 emissions for aviation. Latecoere will design and build the underwing fairing, an all-composite 2-meter-long and articulated assembly mounted with the hybrid-electric propulsion system on the starboard inner wing of the experimental aircraft testbed.

Combining a highly efficient Pratt & Whitney Canada thermal engine with an 1 MW motor developed by Collins Aerospace, also an RTX business, this new hybrid-electric propulsion technology will drive significant improvements in aircraft efficiency by optimizing performance across different phases of flight. The project is targeting a 30% improvement in fuel burn and reduced CO2 emissions, compared to a modern regional turbine aircraft.
