Abstract

Cilj ovog rada je postojeći model noseće linije modificirati za mogućnost analize različitih konfiguracija repa. Potrebno je odrediti gradijent normalne sile po napadnom kutu i gradijent bočne sile po kutu klizanja koji se koriste za određivanje uzdužne i poprečne statičke stabilnosti zrakoplova. Gradijent bočne sile po kutu klizanja određen je na način da se konfiguracija repa zarotirala za -90° oko uzdužne osi što predstavlja analogan problem određivanja gradijenta normalne sile po napadnom kutu. Rezultati su uspoređeni s eksperimentalnim i numeričkim rezultatima te računalnim programom XFLR5 čime je provjerena točnost metode.

Abstract (english)

The aim of thesis is to modify lifting line method for ability to analyze different tail configuration. It is required to determine normal force gradient due to angle of attack and side force gradient due to sideslip angle whice are used to determine longitudinal and lateral static stability. Side force gradient due to sideslip angle is determine with rotated model around longitudinal axis for angle of -90° which present analogous problem of solving normal force gradient due to angle of attack. The results are compared with experimental and numerical results and with software XFLR5 whereby accuracy of method is veryfied.
