PWC62193 Pratt & Whitney Borescope Guide Tube

For the PW308 Pratt & Whitney engine series.

This precision crafted; stainless steel borescope guide tube allows for the corkscrew maneuvering necessary to position the flexible borescope probe for inspections into the most difficult areas of Pratt & Whitney engines.

The PW300 family comprises 4 engine series and 13 models, ranging from 4,700 to 8,000 pound thrust.  This mid size business jet engine and accessory parts are generally classified into three categories – rotatable, expendable and consumable parts. To define and better understand FAA approved aircraft parts, refer to FAA Advisory Circular AC20-62E. Current catalogue availability is subject to change and may be affected by inactivity, supersedure and obsolescence.

According to Wikipedia, The basic configuration of the PW300 is as follows: single-stage fan, driven by a three-stage low pressure turbine, supercharging a four-stage axial/single-stage centrifugal high-pressure compressor, driven by a two-stage high-pressure turbine. An annular combustor is featured. Some versions have an unmixed exhaust, but the PW306 and PW308 include a forced mixer. A Full Authority Digital Engine Control (FADEC) system is incorporated.

The PW300 is a two spool engine with a five stage high pressure compressor driven by a two stage, cooled high pressure turbine and a three stage low pressure turbine driving a robust, advanced technology fan.  A high efficiency  through flow combustion, with a advanced TALON combustion in the latest models, ensures low emissions and fuel consumption,.  A high efficiency exhaust mixer further contributes to the engine family’s low fuel burn and noise.  The latest Full Authority Digital Engine Control (FADEC) in many of the PW300 models provides reduced pilot workload and advanced engine health monitoring, assuring a high standard in aircraft dispatch availability. The result is a compact, lightweight design that powers the majority of the mid size business jets in the market.

The PW307A is a new center-line engine developed specifically for a tri-jet application on the Dassault Falcon 7X. The PW307 was certified by Transport Canada in March 2005.

The PW307A is a 6,100lb-thrust (27.1kN) growth version of the PW306 powering the Fairchild Dornier 328JET regional jet and Gulfstream 200 super mid-size business jet. It will also power the mid-size Cessna Citation Sovereign when it flies early next year

The PW308A has been chosen to power the Scaled Composites White Knight Two, the launch aircraft for Virgin Galactic’s SpaceShipTwo
