The engine-maker says the successful demonstration involved a GE Aerospace CT7 turboshaft engine combined with internally-produced electric machine and power electronics.
GE Aerospace in 2025 plans to use two of the world’s fastest computers, both at US-government-funded research facilities, to study how its open-fan engine concept will integrate with an aircraft’s wings and other structures.
Pratt & Whitney Canada (P&WC) has embarked on a government-supported project to evaluate using hydrogen as fuel for a PW127XT turboprop.
