Study on surface damage to vehicles traveling at hypersonic speeds

NOVEMBER 19, 2019 by¬†University of Illinois at Urbana-Champaign Vehicles moving at hypersonic speeds are bombarded with ice crystals and dust particles in the surrounding atmosphere, making the surface material vulnerable to damage such as erosion and sputtering with each tiny collision. Researchers at the University of Illinois at Urbana-Champaign studied this interaction one molecule at […]

Researchers measure wake of supersonic projectiles

NOVEMBER 7, 2019 by University of Illinois at Urbana-Champaign Imaging technology has vastly improved over the past 30 years. It’s been about that long since the flow coming off of the base of projectiles, such as ballistic missiles, has been measured. Researchers in the Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign used […]
