The turboprop system consists of 3 propeller governors, a governor, and overspeed governor, and a fuel-topping governor. [14] The governor works in much the same way a reciprocating engine propeller governor works, though a turboprop governor may incorporate beta control valve or beta lift rod for beta operation and is typically located in the ...
Propeller governor PCU5000, made by Jihostroj a.s. company, fitted to an American Champion aircraft A constant-speed propeller is a variable-pitch propeller that automatically changes its blade pitch in order to maintain a chosen rotational speed, regardless of the operational conditions of the aircraft.
The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada.Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since.
Constant-speed propeller control system simplifies this for the pilot by introducing a propeller governor, where the lever controls the desired propeller speed instead of the pitch angle. Once the pilot has set the desired propeller speed, the propeller governor maintains that propeller speed by adjusting the pitch of the propeller blades ...

Turboprop, turboshaft and turbofan engines have additional turbine stages to drive a propeller, bypass fan or helicopter rotor. In a free turbine the turbine driving the compressor rotates independently of that which powers the propeller or helicopter rotor. Cooling air, bled from the compressor, may be used to cool the turbine blades, vanes ...
The "passivity" agreement FDIC wants BlackRock to sign is designed to assure bank regulators that the giant money manager will remain a "passive" owner of an FDIC-supervised bank and won’t exert ...
Feathered propeller on the outboard TP400 turboprop of an Airbus A400M. On most variable-pitch propellers, the blades can be rotated parallel to the airflow to stop rotation of the propeller and reduce drag when the engine fails or is deliberately shut down. This is called feathering, a term borrowed from rowing. On single-engined aircraft ...
