Disseny d'un banc de proves per a poder mesurar les pèrdues de fregament i rodadura [sic] de pneumàtics

Dintre del projecte del cotxe de baix consum “Àliga”, vehicle experimental que participa en la “Eco-Shell Marathon”, una competició internacional que es realitza anualment, el projecte tracta del disseny d’un banc de proves per a poder mesurar les pèrdues de fregament dels pneumàtics provant diferents pressions, càrregues suportades, angles de la direcció, tipus de pneumàtics i diversos components del sistema de direcció

Lateral tires characterization: testing, analytical models and applications for aeronautic purpose

The lateral characteristics of tires in terms of lateral forces as a function of sideslip angle is a focal point in the prediction of ground loads and ground handling aircraft behavior. However, tests to validate such coefficients are not mandatory to obtain Aircraft Type Certification and so they are not available for ATR tires. Anyway, some analytical values are implemented in ATR calculation codes (Flight Qualities in-house numerical code and Loads in-house numerical code). Hence, the goal of my work is to further investigate and validate lateral tires characteristics by means of: exploitation and re-parameterization of existing test on NLG tires, implementation of easy-handle model based on DFDR parameters to compute sideslip angles, application of this model to compute lateral loads on existing flight tests and incident cases, analysis of results. The last part of this work is dedicated to the preliminary study of a methodology to perform a test to retrieve lateral tire loads during ground turning with minimum requirements in terms of aircraft test instrumentation. This represents the basis for future works.
