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.

Benefits

  • Straightforward: Simplifies user inputs by eliminating additional aerodynamic approximation methods other than the modified Newtonian technique
  • Uncomplicated: Features unstructured surface grids, simplifying geometry generation
  • Updated: Uses a modern version of the Fortran computer language, thereby eliminating cumbersome and error-prone data constructs and hard-coded problem sizes

Applications

  • Spacecraft design
  • Hypersonic aircraft

Licensing and Partnering Opportunity
