SECURING OF THE SAFETY AND ECONOMY OF ACROBATIC AIRPLANE SERVICE

摘要

In this paper there are summarized results ofrnthe load spectra measurement, which were donernsince 60ties till 1999. It was shown that tworndifferent kinds of "acrobatic operation" shouldrnbe considered. First, the contest acrobatics andrnsecond, the training acrobatics. Both are herernexpressed by load spectra. It is shown thatrnschool and training airplanes are able to fly thernsame "hard" acrobatics as the specialrnairplanes. On the other hand the school andrntraining airplanes are used to NORMAL flyingrnand so their technical life are mostly not usedrneconomical. Therefore it is recommended tornrecord the load history by means of modernrnelectronic fatigue-meter (especially on schoolrnand training airplanes) and fly till the limit staternthat will be allowed by manufacturer.
