Analiza sil pri vzletu jadralnega letala s pomočjo vitla

Munda, Žiga (author), Grebenšek, Andrej (mentor), Kosel, Tadej (co-mentor)

V diplomskem delu je obravnavan vzlet jadralnega letala s pomočjo vitla. Višina, ki jo jadralno letalo lahko doseže, je odvisna od dolžine razvite vrvi in moči pogonskega motorja vitla, vendar pa ta višina ni neskončna. Dolžino vrvi in silo s katero vlečemo letalo omejujeta tako masa vrvi, kot tudi varnostni člen na vrvi, ki varuje jadralno letalo pred preobremenitvijo. Zanima nas do katere mere se še splača povečevati dolžino vlečne vrvi in vlečno silo vitla, da še lahko izvedemo vleko jadralnega letala znotraj omejitev predpisanih v pilotskem priročniku letala.

• Title: Analysis of forces during glider winch launch

Abstract

The diploma thesis deals with glider winch launch. Hight, which glider can reach depends on tow cable length and the towing force of winch, but only to some extent. Length of tow rope and towing force are limited by cable mass and by strength of weak link, this will break before any damage can be done to the glider by overstressing it. Goal of this thesis is to analyze up to what extent is viable to extend tow cable length and increase towing force of winch for achieving greatest launch height, but still to remain inside limitations prescribed in flight manual of a glider.
