Light Unmanned Aerial Vehicle
The objective of this study was to evaluate the ying qualities of a light unmanned aerial vehicle (UAV) developed by the Thai company AVIA Satcom Co., Ltd. Based on the study changes in design was to be suggested to meet stability requirements and recommendations from European Aviation Safety Agency and Federal Aviation Administration. The evaluation was based on two dierent analyses.

First,the stability characteristics in terms of stability modes were examined by creating a light dynamics model of the studied airplane. Secondly the controllability of the vehicle was investigated by examining the control surfaces. It was found that the original design of the UAV was dynamically unstable and that the control surfaces were too large making the airplane dicult to y in trim condition. By studying the stability characteristics of the simulated airplane it could be concluded that the UAV was dynamically
stable for the improved design and thereby meet the requirements and recommendations.
