A NEW PROCEDURE OF ANALYSING ZIG-ZAG TEST (CONTINUED REPORT)

In the previous report, the authors proposed a new procedure of analysing zig-zag tests by which it is posssible to identify the parameters of the second-order mathematical model. In the present report a new method is proposed to predict the various manoeuvring test results from the parameters of only one zig-zag test; the results of the spiral test, reverse spiral test, modefied zig-zag test, yaw-rate zig-zag test, course change test and so on can be obtained by numerical calculations. Next, we make some considerations about the speed drop effect on the results of the zig-zag test, and propose a method to analyse the zig-zag test, taking account of it. Lastly, we make mention of the wind effect on manoeuvring tests.
