Version 2 2

JetPropulsion Library 2.2 is part of Modelon���s 2021.2 release.

New versions of Modelon libraries are sold and distributed directly from Modelon, as well as approved resellers. 

Improvements

  • Replaced old environment models in BasicAmbient with a package of new environment models from Modelon base library, including separate models for atmosphere and individual vehicles.
  • The U.S. Standard Atmosphere 1962 version has been upgraded to 1976 version
  • The new ambient Settings_JPL has been simpilfied and the parameters & variables of the standard atmospheric conditions will be computed from Atmosphere and AirData from the Modelon base library.
  • Mass estimation models (compressor, turbine, duct, burner) now includes an optional flow path coordinate for calculating the gas turbine length.
  • A new method for calculating duct length (based on Kaiser 2020) as a function of radius, is added to the weight estimation of Duct.
  • Complete review of all experiment-annotations.
  • In the turbine cooling models, added option to have physical limits on the cooling effectiveness by setting enableLimiting=true.
  • Enhanced documentation to turbine cooling models.
  • Adding Kurzke cooling models.
  • Clarified the equations for thrust calculations in the Nozzle model.
  • Additional thermodynamic property functions JetPropulsion.Media.TotalStaticProps.Templates.DefaultFlowModel.speedOfSound, JetPropulsion.Media.TotalStaticProps.Templates.DefaultFlowModel.totalDensity, JetPropulsion.Media.TotalStaticProps.Templates.DefaultFlowModel.dynamicViscosity.
  • Improved initialization of complete gas turbine cycles using readDesignData from XML-files.
  • Added functionality to fix synthesis variable outputs in the control blocks for easier debugging and renamed select parameters such as TbuPrscrMax to TbuMaxPrscrPar.

Fixed issues

  • Corrected the A10/Ag table value on position (7,1) in RoundCDNozzle from 7 to 10.
