The paper describes some facilities and capabilities which are currently available at the Aerodynamic Test Department of Aeronautica Macchi. Special wind tunnel testing techniques allow the use of a small scale wind tunnel to obtain useful data for the development of aircraft configurations model work-shop capabilities permit the manufacture of specialized wind tunnel models for detailed analysis of problem areas. The topics covered are updating of the rotary balance facility for the measurement of dynamic derivatives due to roll in the full range of model attitudes assessment of Reynolds number effects on high lift devices of modern design design and manufacture of an afterbody model and manufacture and testing of flutter models.
