Research news on Aerodynamics

Aerodynamics as a research area investigates the behavior of gases, primarily air, and the forces and flow phenomena arising when bodies move through them or when gas flows around stationary objects. It encompasses theoretical, computational, and experimental study of flow regimes (incompressible, compressible, transonic, supersonic, hypersonic), boundary layers, turbulence, flow separation, and aerodynamic forces and moments (lift, drag, pitching, rolling, yawing). The field develops and applies governing equations (e.g., Navier–Stokes, Euler), turbulence models, and numerical methods (CFD), as well as wind-tunnel and flight-testing techniques, to optimize performance, stability, control, and efficiency of vehicles and structures interacting with fluid flows.

Violent rocket particles could reshape future spacecraft design

When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny particles are thrown around at hypersonic speeds. These particles behave in ways that break long-held ...

Next-gen Mars helicopter rotor blades exceed Mach 1

The rotor blades that will carry NASA's next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA's Jet Propulsion Laboratory in Southern California. Data from the tests, which ...
