Abstract:
Aircraft Range extension is a very common modification for today’s aircraft. Using the conformal fuel tanks is an appropriate method for today’s military and civil aircraft. In this thesis, a Design method has been developed for designing these tanks using DSM, CFD and DOE. The main goal in developing the method was to be able to consider these tanks as an add-on feature for the aircraft, which can be designed after the aircraft production. The main aspects of designing the tanks was to identify the consequences of adding the tanks to the aircraft. Due to limited resources, only the Longitudinal static and dynamic stability of the aircraft has been considered.The method introduced here shows good results and can be considered as a design method. The final design showed that the final shape of the tanks relies heavily on the position and shape of the aircraft near tanks position.The tools used here are AAA software developed by DARcorp., MATLAB and Ansys Fluent
