Two simulation projects get NASA annual software prize

Two NASA simulation projects'the Numerical Propulsion System Simulation and the Generalized Fluid System Simulation Program'have won the agency's Software of the Year Award for 2001.

NPSS reduces the time required to analyze aircraft engines andgenerates detailed computer simulations that let engineers test design options without conducting real-life tests, which take more time and money.

Cynthia Gutierrez Naiman of NASA's Glenn Research Center in Cleveland led the development of NPSS. The project team included 39 other Glenn engineers, the Arnold Engineering Development Center at Arnold Air Force Base, Tenn., and nine companies.
GFSSP analyses fluid-flow rates, temperature and pressure in rocket engines, turbo pumps, fuel tanks and fluid distribution systems.

Alok Kumar Majumdar of NASA's Marshall Space Flight Center in Huntsville, Ala., led the development team that included engineers from Marshall and two companies.

NASA has held the software competition since 1994.
