In order to improve their stability and handling, engineers mounted inverted wings profiles1 generating negative lift. Clearly the modified formula does an excellent job. 0 To anyone involved in aeronautics, Formula I cars must seem to be pretty weird devices and so, in order to explain some of the rather unorthodox aspects of FI aerodynamic design, I shall start by retracing the history of aerodynamics in FI a few years to 1968, when it was realised that greater gains could be made by increasing the tyre loads than by trying to reduce the drag. %%EOF 0000001967 00000 n 0000002682 00000 n Downloaded from www.annualreviews.org by Universidade Estadual de Campinas (Unicamp) on 04/17/11.

It is further influenced by the development in professional motorsport, which decreases the variety of designs. Aerodynamics, from Greek ἀήρ aero (air) + δυναμική (dynamics), is the study of motion of air, particularly when affected by a solid object, such as an airplane wing. However, given that the shapes of Formula 1 cars are complex; this project has only focused on the improvement of the aerodynamics of the rear wheels. x�b```f``�``e`�eb@ !6 da�x� R�$������A�Oò,l�����y�+w�Y��:��C���i�|8%�/2�8��\�T���� ��r���ӆ�L��"��18Pk�|_z=,2u~�ج�������~��zC�t��� �Y �GoG�/������4W��{��a�j���~V�����岕��v(9�����:ϴy]Y�,A�H�}Ū�Jh����ٜ���)4s���O�\�hV�������w�h�q��u X&�y��ɴ��_pU�S��6�@�LF(г(�/�IԺC?�Eu[@��f��:9�,�\�}��˼��0�6����t�w{�OK��� z��V~�*�C�z�Jh2����� \����*` �� 0000001883 00000 n 1 - 3 out of 8 pages is developed de Campinas ( Unicamp ) on 04/17/11 as...
