Software- based expertise system for automated design of models and material selection for aerospace engine parts

 

Software- based expertise system for automated design  of models and material selection   for aerospace engine parts

 

 

 

Problem-solving

 

Development of software- based tracking system   to enable decision-making  for the design of basic and assembly parts of air-breathing jet engines and its ground-line installations according to the selection of materials, covering and ways of surface preparing

 

 

 

Problems topicality

 

  • Automated design  of basic and assembly parts of air-breathing jet engines limited by initial process stage.
  • Weight parameter optimization  for basic parts
  • Great number selected models for shorted period
  • Material selection for basic and assembly parts of air-breathing jet engines with various construction.
  • Guidelines related to the use of covering and ways of surface preparing (surface plastic deformations)

 

Advantage

 

  • Providing multy- disciplinary calculations, automated design  of basic parts of aerospace engines;
  • Material selection using data bases to implement in construction. Creating 5 materials-based list with maximum grade;
  • Thermogas dynamic, aerodynamical and strength calculations for compressor and turbine according to 3 section along its heights. Strength calculations for blade and disk junction as well as for disk only.
  • Short time to optimize cycle parameters, its construction as well as its weight parameter. 
 
 
 

Basic parameters

 

  • Data bases with a great number of  physicochemical and mechanical properties of aerospace materials : > 240 types
  • Matrix and fibre enable modelling properties of various unidirectional composite material under variant  temperature. 
  • Relative error under conditions of   modelling basic and assembly parts of air-gas channel: 1–7%.
  • Relative error under conditions of  overall node dimensions determination: 3–17%.
  • Relative error under conditions of node weight determination: up to 21%.
  • Engine materials required  belong to 1-3 range of materials list
