The company was founded in Rockford, Illinois, in 1870 with Amos W. Woodward's invention of a non compensating mechanical waterwheel governor (U.S. patent No. 103,813). [5] [8] Thirty years later, his son Elmer patented the first successful mechanical compensating governor for hydraulic turbines (U.S. patent No. 583,527). [9]
This is achieved by use of a constant-speed unit (CSU) or propeller governor, which automatically changes the propeller's blade pitch. Most engines produce their maximum power in a narrow speed band. The CSU allows the engine to operate in its most economical range of rotational speeds , regardless of whether the aircraft is taking off or cruising.

In this case, speed reference will be 104% and actual speed will be 100%. For every 1% change in the turbine speed reference, the power output of the turbine will change by 25% of rated for a unit with a 4% droop setting. Droop is therefore expressed as the percentage change in (design) speed required for 100% governor action.

Gas turbine engines are primarily controlled by the amount of fuel supplied to the combustion chambers.With this in mind we can say that, the very simplest fuel control for a turbine engine is a fuel valve operated by the pilot.

Woodward and Griffin, along with the current Governor and a third judge, held this power from 1805 until the institution of a legislature in 1824. Woodward and Hull bickered almost constantly. One of Woodward's legacies is the Woodward Code: a series of statutes serving as the basis of the Territorial Supreme Court legal procedures.
