GA-ASI, P&W carry out MQ-25 engine test
General Atomics Aeronautical Systems (GA-ASI) has carried out a successful powered run of the Pratt & Whitney (P&W) PW815 engine that will power its proposed solution for the US Navy’s MQ-25 Stingray refuelling UAS, it was announced on 31 May.
The powered run of the PW815 was carried out with the GA-ASI MQ-25A inlet and exhaust configuration. The test met all objectives and collected data that the team is now evaluating.
David Alexander, president, aircraft systems, GA-ASI, said: ‘GA-ASI has a 14 year history working with P&W and selected the PW815 engine for the MQ-25 based on its performance and fuel efficiency. This performance and efficiency will subsequently translate into more available fuel for the receiving aircraft. Additionally, initial studies have shown the PW815 is well-suited for a carrier environment.’
The GA-ASI and P&W team will now continue risk reduction testing.
