*The results shown here are for an Aluminum model propeller, Op = 5.44 Ibf-s?/#t? and were 
obtained by fairing the experimental air-spin data using the following restraints: 
(F, M)/n? = constant 
(F,,™M,) =constant 
@,  =constant 
Except where indicated in Table 8, all other centrifugal and gravitational loads presented in this 
report are for a Bronze propeller, Pp = 14.48 Ibf-s2/#t?
