Researchers at NASA’s Johnson Space Center have developed an engineering software tool for rapidly generating estimates of hypersonic aerodynamic coefficients and pressures on the surface of a vehicle traveling at speeds above Mach 5. Snewt software requires users to supply a computer model of the vehicle’s outer mold as well as freestream parameters including vehicle orientation and Mach number. The software improves upon other available programs by eliminating little-used solution options, more easily generating a computer representation of the vehicle being studied, and using an updated version of the Fortran computer language. Snewt is written in the Fortran 90 programming language and will run under any operating system if a Fortran 90 compiler is available. This software may be released for U.S. Government purposes only.
This technology is being made available through JSC’s Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
