NASA’s X-59 Quesst program has begun testing the engines of the X-59 jet at the Lockheed Martin Skunk Works facility.
The tests so far have involved running the engines at low speeds to check for leaks and ensure the systems are working properly.
The X-59 is designed to fly at Mach 1.4 (1.4 times the speed of sound) and 55,000 feet, using a modified F414 jet engine.
The unique elongated nose shape of the X-59 is intended to create a softer “thump” rather than a loud sonic boom when breaking the sound barrier.
Upcoming tests will involve more advanced ground testing before the X-59 attempts its first flight, which does not yet have a scheduled date.
Boom Supersonic’s XB-1 Jet:
Boom Supersonic’s XB-1 supersonic demonstrator aircraft set a new speed record of Mach 0.82 (629 mph) during its 7th test flight.
This was the XB-1’s highest speed and altitude (23,015 feet) achieved so far in the flight test program.
The tests focused on expanding the aircraft’s flight envelope and verifying its performance and handling as it approaches supersonic speeds.
The XB-1’s performance is meant to inform the design and development of Boom’s planned Overture supersonic airliner.
Boom says the XB-1 is progressing steadily toward its goal of breaking the sound barrier at Mach 1 in future test flights.
