Modification in Structural Design of L-13 “Blanik” Aircraft's Wing to Obtain Airworthiness

The article deals with structural analysis and the design of the current technical condition of the aircraft L-13 “Blanik”. Based on fatal incident and it's further investigation revealed, that one of the reason may have been caused by material fatigue. Therefore majority of this type of aircraft have lost airworthiness. Currently most aero-clubs and aviation schools, mainly in the European Union, North America and Australia, stopped using this type of aircraft. Modification of wing spar gives the opportunity to regain airworthiness. High financial costs of rebuilding the structure, which currently could perform only authorized organizations, are for many aero-clubs and aviation schools unreachable. The aim of this work is to consider safety risks and required flight characteristics in the construction design using a (3D) models and changes in building wings, changes in materials or changes in production technology followed by simulation and mathematical analysis in the time of operation. If acceptable results, the authors would like to implement them in practice and help to maintain airworthiness for the glider L-13 “Blanik” and integrate it back to common air traffic.
