The dream of supersonic travel just got a major boost. Boom Supersonic, the company aiming to bring back supersonic passenger flights, has begun testing a crucial component of their Symphony engine – the combustor – using a 3D-printed rig. This is a significant milestone in their quest to develop the Overture, a supersonic airliner that promises to revolutionize travel.

The Power of Print
The key takeaway here is the innovative use of 3D printing technology. Boom Supersonic was able to create a full-scale, 1/8th section combustor rig in just eight weeks using stereolithography (SLA) 3D printing. This rapid prototyping capability is a major advantage, allowing them to iterate and optimize the design quickly and efficiently.
Testing, Testing, 1, 2, 3...
The initial tests are focusing on the aerodynamics of the combustor. This involves injecting smoke through the fuel nozzles to visualize airflow patterns. This data is crucial for ensuring efficient combustion and minimizing fuel consumption – a critical factor for any aircraft, especially supersonic ones aiming for commercial viability.
Beyond Aerodynamics
But Boom Supersonic isn't stopping there. This initial test is just the first phase of a two-phase pressure drop test. Further testing will evaluate factors like nozzle spray distribution, droplet size, and even emission data at various altitudes. The ultimate goal is to optimize the combustor for peak performance throughout the Overture's entire flight envelope.
Symphony of Progress
The successful completion of these rig tests marks a major step forward for Boom Supersonic. It demonstrates their progress on the Symphony engine and their commitment to bringing supersonic flight back to the skies. This is just the beginning, though. Boom Supersonic plans to individually evaluate all major Symphony components before moving on to integrated power plant system testing.
The Supersonic Future
The success of Boom Supersonic's Symphony engine and Overture aircraft could reshape the way we travel. Imagine cutting travel times across continents in half. Business trips to distant locations could become daily commutes. While there are still challenges to overcome, particularly regarding sonic booms and environmental impact, Boom Supersonic's progress with their 3D-printed combustor rig testing brings the supersonic future a step closer.
