NASA’s quiet supersonic X-59 now has the engine that will power it in flight.
The installation of the F414-GE-100 engine took place at Lockheed Martin’s Skunk Works facility in Palmdale, California, earlier this month, marking a major milestone as the X-59 approaches the completion of its assembly.

The 13-foot-long engine from General Electric Aviation packs 22,000 pounds of propulsion energy and will power the X-59 as it flies at speeds up to Mach 1.4 and altitudes around 55,000 feet.

“The engine installation is the culmination of years of design and planning by the NASA, Lockheed Martin, and General Electric Aviation teams,” said Ray Castner, NASA’s propulsion performance lead for the X-59. “I am both impressed with and proud of this combined team that’s spent the past few months developing the key procedures, which allowed for a smooth installation.”

The X-59 team will follow the aircraft’s assembly with a series of ground tests and ultimately, first flight in 2023.

NASA’s X-59 is the centerpiece of the agency’s Quesst mission. The aircraft is designed to reduce the sound of sonic booms, which occur when an aircraft flies at supersonic speeds, to a quiet sonic “thump.” This will be demonstrated when NASA flies the X-59 over communities around the U.S. starting in 2025, with the goal of providing the data necessary to open the future to commercial supersonic flight over land, greatly reducing flight times.

I note that the NASA X-59 is strikingly similar to the 1950's Douglas X-3, except for the dorsal engine inlet's arrangement on the X-59 compared to the dual upper fuselage air intake arrangement on the X-3.

Douglas manufactured just one airframe. The X-3 flew a total of 26 flights between 1952-1955. This slender, jet-powered aircraft tested such new materials as titanium and collected data on stability and control, pressure distribution, and flight loads. The X-3 failed to achieve the high speeds for which it was designed, due to a lack of turbo-jet engine thrust then available, but pioneered the use of titanium and contributed to the development of aircraft tire technology for high speed landings.

I was amazed when I compared the similarities in design between NASA's X-59 and the legacy Douglas X-3, except for the stubby conventional wings on the X-3 and the delta wing of the X-59 as well as the differences in the arrangement of the air intakes, from the 1950's era heyday of aircraft design.
