Harnaś-3, new generation of aerobatic airplane, comprehensive structure strength analysis

Wojciech Grendysa , Marek Jonas

Abstract

The object of the static strength analysis presented in the following paper is an aerobatic airplane Harnaś-3. It is a new generation of an aerobatic airplane and its unusual arrangement makes it possible to make aerobatic maneuvers that are not possible to do by other airplanes. The untypical arrangement of the aerobatic plane Harnaś-3 causes that the strength analysis of its structure is particularly complex. A spatially developed structure requires a comprehensive approach, taking into account both the specific properties of composite materials and the need to analyze the strength ratio for various cases of external loads, appropriate for aviation regulations. The methodology presented in this article allowed to improve the structure of the Harnaś-3 aircraft to reach the weight of a complete structure of only 235 kg, which allows building an aircraft lighter than the competitors.
