Abstract
This project presents work performed by the Institute of Aerospace Engineering, Brno University of Technology. The primary purpose of this work was to estimate the aeroelastic response of a light aircraft under gust loads. In the past, the gust response has been investigated using the Pratt - Walker formula. This formula is derived from the response of a rigid airplane to a discrete gust. However, the Pratt-Walker formula does not capture either the stochastic nature of continuous turbulence or the effects of structural flexibility. The analysis described here was performed using the advanced FEM software package MSC Nastran.

The aerospace industry tends to deliver optimized products to specific areas of aeronautical use
Within the guidelines of the ‘rational analysis’ required by the regulations, this paper provides a comparative analysis of gust load estimation methods
The results clearly indicate the qualitative and quantitative part of the glider computational gust response analysis
Summary
The aerospace industry tends to deliver optimized products to specific areas of aeronautical use. Even the smallest and simplest, are the result of a complex design approach that has required long-term development, it is occasionally useful to consider a reevaluation of some design features to improve the specific properties and qualities of planes. Within the guidelines of the ‘rational analysis’ required by the regulations, this paper provides a comparative analysis of gust load estimation methods. Through a closer understanding of the gust phenomenon we will be able to make a more precise prediction of the gust loads acting on the structure. There are two methods widely accepted by the aeronautical authorities. Both of them are implemented in the world leading sets of aeronautical safety requirements
