Parachute Emergency Systems for Very Light Sport Planes
Šorf, Oldřich ; Salga, Jaroslav (referee) ; Daněk, Vladimír (referee) ; Třetina, Karel (advisor)
This PhD thesis describes parachute rescue systems for small planes and focuses on their functionality in the border areas of the flight envelope, especially at very low altitudes and low airspeeds of flight (fall). For extending the functionality of the rescue system in extreme areas of usability envelope, was founded an innovative dividable parachute slider, which works normally at high speed, but at the low airspeeds does not limit the opening time of the canopy. Structural design of this slider is the subject of a new patent application “Parachute opening speed regulation device”, filed with Industrial property Office in Prague on August 14, 2014 under number 2014-543 PV. The PhD thesis further contains computational principle of circular parachute opening and the structural design. For verification of the dividable slider functionality, a parachute model has been constructed and subjected to a series of drop tests. The main benefit of the PhD thesis is extending the usability of rescue system into its statistically most frequent use, i.e. into low altitudes and low airspeeds of flight (fall).
