Abstract

This paper presents some of the results of the dynamic model tests of the XC-142A aircraft. Of particular interest are the testing techniques associated with propeller whirl flutter. The model incorporates simulation of the engine mount dynamics, of the propeller dynamics, and of the shafting dynamics in addition to the regular structural dynamics. The model is used to check mount failure conditions with respect to flutter and to check dynamic loads with respect to propeller unbalance. The model will also be used in further tests to measure total aerodynamic coefficients through the zero angle of attack range.
