Abstract : Gas turbine performance computer programs have become the principal method of describing engine performance. These programs are used in the thousands of computations necessary in the design and performance evaluation of modern aircraft propulsion systems. A team of engineers, computing analysts, and mathematicians has been assigned to investigate methods to make these Pratt and Whitney Aircraft engine simulations converge more quickly, with higher stability and reliability. This paper presents the results of their research to date. (Author)
