Boom Supersonic has released imagery borne from its collaboration with NASA. Boom’s demonstrator aircraft, XB-1, recently underwent supersonic flight tests.
The collaboration yielded groundbreaking images and data that pave the way for a new era of commercial supersonic travel.
Through its flight test and research program, the pioneering company aims to revolutionize air travel with its supersonic Overture airliner.
A Glimpse at Supersonic Flight Physics
On 10 February 2025, during XB-1’s second supersonic flight, NASA’s specialized teams captured the Schlieren photography. This technique, a marvel of optical engineering, allows for the visualization of shock waves generated as XB-1 pierced the sound barrier.
These images depicting the dynamic interplay of air density around the aircraft. They offer a unique glimpse into the physics of supersonic flight.
This achievement builds upon XB-1’s previous historic flight in January, where it became the first independently developed jet to break the sound barrier and the first civilian supersonic jet built in America. These accomplishments underscore Boom Supersonic’s commitment to pushing the boundaries of aviation technology.
Beyond the visual spectacle, NASA also collected crucial data on XB-1’s acoustic signature. Notably, analysis revealed that no audible sonic boom reached the ground during the supersonic flight. This is a pivotal finding, addressing one of the primary concerns surrounding supersonic travel.
Revealing the Invisible
“This image makes the invisible visible—the first American-made civil supersonic jet breaking the sound barrier,” stated Blake Scholl, Founder and CEO of Boom Supersonic.
“Thanks to Geppetto’s exceptional flying and our partnership with NASA, we were able to capture this iconic image. We also confirmed that XB-1 made no audible sonic boom, which paves the way for coast-to-coast flights up to 50% faster.”
Capturing Schlieren images requires meticulous planning and execution. Pilot skill is paramount, and Boom’s Chief Test Pilot, Tristan “Geppetto” Brandenburg, maneuvered XB-1 to the precise location and time required for NASA’s photography.
He positioned the aircraft against the backdrop of the sun over the Mojave Desert, allowing for the documentation of the changing air density at speeds exceeding Mach 1.
Co-Ordination with NASA
The process involved sophisticated technology and collaboration. NASA provided precise waypoints, which Boom’s team utilized to rapidly develop avionics software.
This software guided the pilot through the specific points in space needed to eclipse the sun. NASA’s ground telescopes, equipped with specialized filters, detected the air distortions, including shock waves, around the supersonic aircraft.
Furthermore, both NASA and Boom conducted extensive modeling to predict XB-1’s flight parameters. These simulations indicated a high likelihood of achieving “Mach cutoff,” a phenomenon where the sonic boom refracts in the atmosphere and dissipates before reaching the ground.
This occurs when an aircraft breaks the sound barrier at a sufficiently high altitude, with specific speeds varying based on atmospheric conditions.
To confirm these predictions, microphones and sound pressure level recording devices were strategically placed along the flight path.
The data collected from these devices validated Boom’s assessment: supersonic flight without a disruptive sonic boom is indeed possible. This aligns with prior NASA research aimed at bringing supersonic commercial travel to the forefront.
“Boomless Cruise”
Building on these successful tests, Boom Supersonic announced its intention to implement “Boomless Cruise” in its Overture airliner. This technology is derived from the data collected during XB-1’s test flight program.
It will enable Overture to fly at speeds up to Mach 1.3 without generating an audible sonic boom. This innovation promises to reduce U.S. coast-to-coast flight times by up to 90 minutes.
The conclusion of XB-1’s groundbreaking flight test program marks a pivotal moment. The aircraft will now return to its birthplace in Denver, Colorado.
Boom Supersonic will now concentrate its efforts on applying the knowledge and technology gained from XB-1 to the development of the Overture supersonic airliner. With 130 orders and pre-orders from major airlines like United Airlines, American Airlines, and Japan Airlines, Overture is poised to redefine air travel.
Boom Supersonic has also made significant progress in its manufacturing capabilities. In 2024, the company completed construction of the Overture Superfactory in Greensboro, North Carolina. This facility will eventually produce 66 Overture aircraft per year. This facility represents a significant investment in the future of supersonic travel.
The collaboration between Boom Supersonic and NASA has yielded remarkable results, bringing the dream of sustainable, commercially viable supersonic flight closer to reality.
The data collected and the images captured during XB-1’s test flights represent a significant step forward in aviation history.
