General Motors stirling 4L23 engine test results.
The engine of the future project
The following is a table with the test results of the stirling 4L23 Engine, built by general motors.
I found it on:
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19830022057_1983022057.pdf
The information can be used to calibrate stirling cycle engine design programs.
You can select the part between the ======= lines, and past it in a simple wordprocessor
like Notepad or Wordpad and save it with the name STGM4L23.TXT
You can use this file as input file in the Stirling Engine Design Program you find on:
stirlingmartini.html
For the html-javascript version of the Isothermal second order calculation Program (Written by William R. Martini in Fortran) Click here
The program is in the source code.
Also the ADIABATIC SECOND ORDER DESIGN PROGRAM written in Fortran by P.A. Rios is published in a quickbasic version on this site.
