Aerodynamics of NASA X-59 Quiet Supersonic Technology (QueSST) Explained

Can we fly faster than sound without the boom? NASA’s X-59 QueSST proves it’s possible — and here’s how the physics look up close. In this short simulation study, Stallion 3D reproduces the quiet-supersonic pressure pattern at Mach 1.45 and 55,000 ft, matching conditions used in NASA’s low-boom flight research. The result: a distributed sequence of gentle compressions along the nose, smooth canopy-shoulder interactions, and controlled aft-body shaping — all key to turning a sonic boom into a soft “thump.” Stallion 3D’s built-in atmosphere model and Cartesian solver capture these effects directly from geometry — no body-fitted mesh required. The study demonstrates how first-principles CFD can reveal the same flow behavior reported by the X-59 program, confirming that quiet supersonic design can now be explored on a standard workstation. 👉 Learn more: https://www.hanleyinnovations.com 👉 Software used: Stallion 3D by Hanley Innovations 👉 Follow for more real-world CFD and aerodynamics insights. ➡️ If you enjoy this content, buy me a coffee 🍵 https://buymeacoffee.com/patrickhanle...
