Abstract
A speed responsive control device is useful for preventing a dangerous overspeed condition of a propulsor. The device begins governing before the dangerous overspeed condition occurs through the use of an acceleration responsive mechanism which actuates the spool of a governor pilot valve. The spool is also actuated by a speed responsive mechanism in the form of a flyweight governor. The control device thus anticipates dangerous overspeed conditions to make necessary adjustments such as blade pitch corrections, to prevent a dangerous overspeed condition.
