Component Improvement Program Task 83-01, 36E133 Air Turbine Starter

摘要

The objective of this task was to replace the mechanical cutout switch with a solid-state electronic cutout switch to improve accuracy and reliability of the automatic start cycle termination in the S-3A and F-14A aircraft. The function of the cutout switch is to terminate the start cycle at a predetermined speed. It was determined that the existing electronic circuit can be used for the 36E133/123 with only a minor resistor change to accommodate the subject unit's cutout speed. Breadboard testing was successfully completed and satisfactorily demonstrated feasibility.
