Civilian long endurance UAV – design challenges

Abstract

This paper presents a selected aspect of design activity devoted to optimising HALE and MALE UAVs. The project is taking place at Warsaw University of Technology under the V Framework of European Union in the CAPECON project. This paper deals with wing airfoil selection, defining of the configuration layout and power unit integration. A brief overview of wing sections developed in some design centres (mainly in Israel Aircraft Industry and in Northrop Grumman) is included. Aircraft layout depends on the mission and sensor selection and is discussed using the examples of PW‐103 and PW‐114. Engine suspension and integration with aircraft is included in the analysis because if it is not properly analysed, it can lead to an excessive vibration and fatigue of the whole aircraft structure.
