| Abstract: | The data analysis technique of free flight projectiles isdiscussed with the linear aerodynamic model. Methods and some computerprogrammes in FORTRAN 77 for obtaining aerodynamic coeffieients fromfree flight trials of projectiles have been devoloped. In order to test theprogrammes the data from free flight triale of projectiles and those arti-fitially generated are reduced. Results of the reduction are satisfactory.It is shown that these methods and programmes can be applied to reducethe data from free flight experiments. |
