Jesùs San Pedro Pérez, Radoslaw Zawadzki: 3628. Control Surfaces – Mass Properties under Control. 2014.



The mass modeling process is part of the A/C development process, creating mass distribution data as input for loads and aeroelastics. The mass properties derivations is a key milestone in building aircraft dynamic and flutter analyses and further more for dimensioning of primary structure.
This paper gives an overview about A/C control surfaces and discusses the results of appropriate mass properties as input variable for flutter investigations. A simple example illustrates the evolution of mass properties on the process throughout the different maturities during development.
Furthermore impact of uncertainties related to estimated mass and finally the validation of mass properties is taking into account as a key aspect in terms of certification requirements.
