Estimation des masses, des centres de gravite ainsi que des moments d'inertie de l'avion cessna citation X

The masses, centers of gravity and moments of inertia are the main parameters in the three phases of the design of the aircraft. They are of extreme importance in the studies of the stability and proper functioning of the aircraft by modeling and simulation methods. Unfortunately, these data are not always available given the confidentiality of aerospace field. A question arises naturally: How to estimate the mass, center of gravity and moments of inertia of an aircraft based on only its geometry? In this context in which this thesis is realized, the masses are estimated by Raymer`s methods. The aircraft described in procedures based on mechanical techniques engineers are used for determining the centers of gravity. The DATCOM is applied for obtaining moments of inertia. Finally, the results obtained are validated by using the flight simulator at the LARCASE corresponding to Cessna Citation X. we conclude with a representation of an analytical model that sum up the different step to follow up for estimating masses, centers of gravity and moments of inertia for any commercial aircraft.
