Tsukanov R. U. Mathematical simulation of fuel burn schedule effect on airplane center-of-gravity position [Електронний ресурс] / R. U. Tsukanov // Авиационно-космическая техника и технология. - 2016. - № 1. - С. 18–29. - Режим доступу: http://nbuv.gov.ua/UJRN/aktit_2016_1_4 Formulas to describe shape of fuel tanks arranged in wings, wing center section and fuselage are proposed on the base of wing shape analysis of real transport category airplanes. Methods of fuel burn sequence designation and fuel transfer methods are analyzed. Method accounting ribs with baffle check valves influence on airplane center-of-gravity position is considered. Algorithm for transport category airplane center-of-gravity position calculation depending on current fuel level in tanks and pitch angle, accounting specified number and arrangement of fuel tanks in wings, wing center section and fuselage, fuel burn schedule, and number and arrangement of ribs with baffle check valves is proposed. Basing on this algorithm and its program implementation, calculation of center-of-gravity position in the process of fuel utilization was carried out for some passenger airplanes (Ан-148, B-737-400, A-310, DC-10, B-747). The algorithm proposed can be used for determination of reasonable number and arrangement of ribs with baffle check valves, more complicated mathematical models creation, and also for making course and diploma projects.
