Propeller control or Governor - Adjusts the propeller blade pitch and regulates the engine load as necessary to maintain the set revolutions per minute (RPM). See the section on propeller below for details. Mixture control - Sets the amount of fuel added to the intake airflow.
The PW8000 engine aimed for 10% lower operating costs, or $600,000 per aircraft annually. [3] The PW8000 had an 11:1 bypass ratio (twice that of the V2500), a 40:1 overall pressure ratio, and 13 rotor stages instead of the 17 [4] in the V2500 for similar thrusts. Preliminary development was to end by June 1, the first test for 10 months later ...
The first British turboprop engine was the Rolls-Royce RB.50 Trent, a converted Derwent II fitted with reduction gear and a Rotol 7 ft 11 in (2.41 m) five-bladed propeller. Two Trents were fitted to Gloster Meteor EE227 — the sole "Trent-Meteor" — which thus became the world's first turboprop-powered aircraft to fly, albeit as a test-bed ...
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.
The PW150 engine was introduced on 24 April 1995, when Bombardier selected the engine for the launch of its de Havilland Dash 8-400 regional turboprop. The PW150 was a higher-power version of the PW100 series, with the low-pressure compressor changed from a single-stage centrifugal compressor to a three-stage axial compressor , and the turbine ...
The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was designed in the 1950s by Garrett AiResearch , and produced since 1999 by successor Honeywell Aerospace . The engine's power output ranges from 575 to 1,650 shaft horsepower (429 to 1,230 kW).
OpenVSP displays a graphical user interface upon launch, built with FLTK.A workspace window and a "Geometry Browser" window open. The workspace is where the model is displayed while the Geometry Browser lists individual components in the workspace, such as fuselage and wings.
The Pratt & Whitney Canada PW800 is a series of turbofan engines in the 10,000–20,000 lbf (44–89 kN) thrust class, manufactured by Pratt & Whitney Canada.Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G.
