contd. -4- 5th Test. Conditions. Torque reaction dampers set to have a friction load of 22 lbs at a leverage of 5.25 inches. Torque reaction. The torque reaction caused 25% more movement of the wings. The period started at 9 MPH. maximum 10.1/2, finished at 12 MPH. The gear lever had more amplitude than the 3rd test. Booms. In Front Seats. These were 10% less pronounced than the 3rd test. The periods were similar to the 3rd test. In Rear seats. These were hardly noticeable 5% increase than the results obtained in the second test. Steering. If anything, the oscillations were increased, no other features could be noted. Jelly-ing of the front wings. These were increased 10 to 20% with higher periods. We have sent you a summary of these tests which we consider give the best all round results, i.e. 3rd test. We consider that no one would object to the slight booms noticed. GWHancock. | ||
