Analysis-Plane and engine makers in tug of war over future jet servicing profits
RTX•Technology choices are still being debated
The tug of war over cash flows coincides with an interlocking debate over engine designs.
CFM's goal is a radical "open-fan" design that would be harder to offer as a choice alongside a competing model and may lend itself more easily to risk-sharing, industry sources said.
Both Pratt and Rolls favour a more conventional design, but all are exploring alternatives, Leeham News has reported.
Until now, the debate has been on paper. Future engine technology existed mainly in computerised images presented at air shows or in scaled models in wind tunnels.
On Monday, GE Aerospace and BETA Technologies stole the opening of the show by flying a turboprop fitted with a hybrid-electric engine across the Atlantic at commercial altitude and displaying it in the prestigious Farnborough flying display.
