On July 29, 2022, General Atomics Aeronautical Systems, Inc. tested a PT6 E-Series model turboprop engine from Pratt & Whitney Canada on GA-ASI’s MQ-9B SkyGuardian Remotely Piloted Aircraft.
Multiple full-power engine tests were performed at GA-ASI’s Desert Horizon flight operations facility in El Mirage, Calif.
“We’ve enjoyed a long-term relationship with Pratt & Whitney,” said GA-ASI President David R. Alexander. “Integrating their PT6 E-Series engine onto our MQ-9B SkyGuardianÆ aircraft offers an alternate option for future customers that includes a 33 percent increase in power, dual channel electronic propeller and engine control system, as well as all the benefits of the PT6 engine family.”
The PT6 E-Series is a reliable and versatile turboprop engine family that will deliver the performance characteristics required as GA-ASI continues its development of MQ-9B capabilities.
“Our PT6 E-series is the ideal engine for this mission and we look forward to working with General Atomics on this important program,” said Jill Albertelli, president of Pratt & Whitney Military Engines.
MQ-9B represents the next generation of RPA system having demonstrated airborne endurance of more than 40 hours in certain configurations, automatic takeoffs and landings under SATCOM-only control, as well as a GA-ASI developed Detect and Avoid system. Its development is the result of a company-funded effort to deliver an RPA that can meet the stringent airworthiness certification requirements of various military and civil authorities.
GA-ASI has enjoyed a long-term collaboration with Pratt & Whitney for over a decade with their turbofan engine for GA-ASI’s MQ-20 Avenger RPA.
