a counter rotating integrated shrouded propfan (crisp) is investigated for civil aircraft application to reduce field consumption, to reduce noise, and to increase take off thrust limitations in size of the propfan engine and the enormous centrifugal forces caused by the fan blades, led to the use of carbon fiber reinforced plastics (cfrp) material for the blades. the design of the joint between the cfrp fan blades and the titanium blade roots is considered. a feasibility study carried out recommends a combination of riveting and adhesive bonding for the cfrp/titanium joint of the experimental propfan. the study contains recommendations of geometry, surface treatment, type of adhesive, and bonding process as well as a strength evaluation of the joint. tests performed to evaluate the joint between titanium blade root and cfrp are listed the experimental program will be finished by the end of 1991
