Instantaneous Type Shaft Revolution System
Abstract
The system was set up at this Laboratory and its operation closely observed while under test for endurance, accuracy and shock integrity. At the start and finish of the 600 hours endurance test, the recorded revolutions on the port and starboard transmitter mechanical counters and the port and starboard and averaging counter were logged. While under endurance, the system was operated at an average speed of 317 RPM and the direction of rotation of the transmit shafts was reversed for one hour in every twenty-four. At the conclusion of this test, the system was operated for accuracy. Then one of the shaft transmitters was subjected to shock and the system again operated for accuracy. The master transmitter under test proved to be to be rugged in design and accurate in operation. However, the equipment submitted is not a finished product and was submitted for preliminary tests to determine the suitability of the instrument design and its practicability.
