the Medium PT6 added another power turbine stage(2) -41 thru the -60 engines [30] the PT6B is a helicopter turboshaft model, featuring an offset reduction gearbox with a freewheeling clutch and power turbine governor, producing 1,000 horsepower (750 kilowatts) at 4,500 rpm.
Congress only approved the purchase when it was assured that a U.S. source would be found for the PT6T engines. This source was Pratt & Whitney Engine Services in Bridgeport, West Virginia, which was established in 1971 to assemble and test new T400-WV-402 engines. As a result, the U.S. military ordered 294 Bell 212s under the designation UH-1N ...
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
The engine was first run in August 1967 before being test flown on an Avro Canada CF-100 Canuck in an underslung external test pod. [3] In 1975 a unique over-wing installation in place of Pratt & Whitney Canada PT6 turboprops was fitted to a Beechcraft Super King Air and flown for 93 hours to investigate the use of turbofan engines on that ...
Basler Turbo Conversions was founded in 1990 solely focused on converting existing C-47/DC-3 airframes into the BT-67. [2] Basler configures each new build to the client's specifications.
The PC-21 is powered by a single Pratt & Whitney Canada PT6A-68B turboprop engine of 1,600 shaft horse power, which drives a five-bladed graphite scimitar propeller manufactured by Hartzell; [3] [8] it has been claimed by Pilatus that the PC-21 possesses speed and climb rates previously normally performed only by jet-powered aircraft.

The 2,500 lbf (11 kN) thrust PW625F demonstrator engine was first run on 31 October 2001. [1] It flew in late 2002. [2] In 2002, the PW610F was selected for the Eclipse 500 twinjet, replacing the EJ22 as Williams was unable to reach sufficient reliability. The 950 lbf (4.2 kN) thrust engine was certified by Transport Canada on 27 July 2006. [3]
In March 2018, Pacific Aerospace launched an updated variant, the Super-Pac XL, with a 900 hp (670 kW) PT6A-140A up from 750 hp and a four-blade 108in (270 cm) Hartzell propeller. It competes with the Supervan 900 re-engined Cessna 208 Caravan with a 900 hp Honeywell TPE331 and 110in four-blade Hartzell propeller. A modified P-750 is ground ...
