Title:Real-Time Modeling Methods for Gas Turbine Engine Performance
Issuing Committee:S-15 Gas Turbine Perf Simulation Nomenclature And Interfaces
Scope:This SAE Aerospace Information Report (AI) provides a review of real-time modeling methodologies for gas turbine engine performance. The application of real-time models and modeling methodologies are discussed. The modeling methodologies addressed in this AIR concentrate on the aerothermal portion of the gas turbine propulsion system. Characteristics of the models, the various algorithms used in them, and system integration issues are also reviewed. In addition, example cases of digital models in source code are provided for several methodologies.Product Code:SAE MAM4427
Title:Magnesium Alloy Sand Castings 4.0y 2.3nd 0.7zr Solution and Precipitation Heat Treated
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers a magnesium alloy in the form of sand castings. These castings have been used typically for parts requiring a combination of light weight, high yield strength up to 300 degrees C and relatively high corrosion resistance, but usage is not limited to such applications.
