Development of an 18cm Micro Air Vehicle : QUARK

Abstract : This paper describes the development of the QUARK micro unmanned air vehicle. The main objective of the study is to show the feasibility of designing an autonomous MAV smaller than 20 cm by using open-source programs and off-the-shelf components. Effort is given to show how to choose the system components and the design variables correctly in order to end up with an optimum design. An open-source multi-disciplinary conceptual aircraft design program called CDSGN is used in order to select the appropriate wing planform and the optimum battery capacity. Propeller and electric motor are selected throughout an optimization procedure, which analyze the performance of each suitable off-the-shelf propeller and motor combination for the specific mission requirements of the new design. A 2 cm×2 cm custom autopilot board is specifically designed according to the requirements of the QUARK. The modelization of the MEMS sensors (Micro-Electromechanical Systems), that are used on the autopilot, is described and analysed in order to improve the stabilisation and the navigation of the aircraft. Longitdinal dynamics of the vehicle are examined by using an innovative technique, and following that, corresponding flight control gains are tunned prior to the outdoor flight test. The first prototype has been flown and a smaller 15.9 cm version is designed according to the obtained results. The expected endurance for the final version is over 35 minutes with reaching up to 35 km of range.
