EFFECTIVENESS OF THE GOODYEAR SIX-POINT POWER PLANT MOUNTING IN CONTROLLING VIBRATION IN THE NORTH AMERICAN AT-6C AIRPLANE

摘要

Results of flight tests are presented for the standard engine mount installation and the experimental installation of the Goodyear Mount in the North American AT-6C airplane. The vibratory Motion of the power plant in given in the form of graphs showing the variation of power plant vibratory response in six degrees of freedom. The results are inter pretend in detail and a brief resume of vibration theory is presented. A description of the instrumentation is given with photographs showing the test installation.
