Requirements for Digital Computer Simulation of Gas Turbine Propulsion System Performance. Phase I. Steady-State and Transient Engine Performance Simulation

摘要

Present and near-future requirements for the addition of digital computer simulation of gas turbine engine steady-state and transient performance to the present Engine Test Facility and Propulsion Wind Tunnel Facility digital data capability were determined based on information and guidance provided by the Air Force Aero Propulsion Laboratory and various gas turbine engine manufacturers. During Phase I of this study, digital computer high-speed core memory size and throughput times were determined and are presented for several modern steady-state and transient mathematical model simulation programs. Display requirements were also determined and are presented for full utilization of the mathematical model results, off-line and on-line. Some preliminary results on dynamic compressor mathematical models are discussed. (Author)
