\nThis article is about the Pilatus Porter engine compartment and everything you can find in front of the fire wall when you open the cowling doors. \u00a0I saw Pilatus Porter’s very short take off and steady steep climb right after it, plus many strange\u00a0in-flight maneuvers\u00a0proving the engine’s high power.\u00a0So it was a suprise for me to see it live – relatively small looking – inside that long Porter’s nose. You can judge for yourself \ud83d\ude42<\/p>\n
<\/p>\n Let us begin with the firewall – the cross wall placed between the cockpit and the engine compartment. The camera is looking at the right-hand (starboard) side of the airplane nose section.<\/p>\n The light green surface in the upper left corner of the picture above is the windscreen. Please note – the fire wall surface was left unpainted.\u00a0<\/em><\/p>\n Now the camera is in the same place but a bit higher looking more down (picture below)\u00a0to see the bottom.\u00a0The engine is on your right.<\/em><\/em><\/em><\/p>\n The upper picture was shot without the flash so you can see the light bleeding through the air outlets – three parallel slots in the rounded plate at the base.<\/em><\/p>\n Now we can look at the fire wall from the opposite side. Here you are – the camera is looking at the firewall from the left-hand (port) side of the plane, the engine is on your left now (following pictures):<\/em><\/p>\n Here you can better sense the high shine of the fire wall plate (picture below).<\/em><\/p>\n Both the engine cowling doors were shot in opened position. Their inner structure is well visible here. Please do not miss the safety prop rods – two for each door.<\/p>\n Opened right-hand (starboard) engine door (upper picture) and the left-hand (port) side door (lower picture). Please do not miss the cylindrical mesh (the inlet screen) in the lower left portion of the picture below and the engine air inlet well visible behind it.<\/em><\/p>\n a\/ Right-hand (starboard) side<\/span><\/strong><\/p>\n Pilatus Porter is powered by the\u00a0Pratt Whitney PT 6A-27<\/a> engine according to the info panel placed nearby. You can find this turboprop engine cutaway visiting this link<\/a>.<\/p>\n Engine photographed from the right-hand (starboard) side of the plane.<\/em><\/p>\n The engine exhaust pipes were covered by the textile cups (upper picture). If you need to see the whole exhaust shape, please visit the\u00a0walkaround\u00a0chapter in my previous Pilatus detailing post<\/a>.<\/em><\/p>\n The brown hose-pipe with a red sticker and black repeating text “FUEL”\u00a0<\/em>on it should connect the fuel pump with the F.C.U.\u00a0Another two brown hose-pipes have a yellow sticker. The\u00a0repeating text on it is “LUBRICATION”.<\/em><\/em><\/em><\/p>\n The blue battery (in the lower left portion of the upper picture) is labeled as “\u00d6BH BORDBATTERIE”.<\/em><\/p>\n Now let us go nearer to the propeller. We can see the rear side of spinner here:<\/em><\/p>\n A closer look (below) is the cut-out from the picture above.<\/em><\/p>\n This is the end of the engine where we can find\u00a0the propeller shaft\u00a0protruding from it.<\/em><\/p>\n Nearly identical photographs – the upper one was shot without the flash light due to the more precise colour definition, while the lower one was shot using the flash light to see the details more sharply.<\/em><\/p>\n We can see some propeller and spinner details here too. Please do not miss the\u00a0placement of the\u00a0propeller blade stickers and the HARTZELL stamp.<\/em><\/p>\n The black bars on the propeller blades close to the spinner are the electrically heated\u00a0\u00a0De-ice Boots<\/a>.<\/em><\/p>\n b\/ Center<\/span><\/strong><\/p>\n Now let us knee down under the propeller and look up. We will see the portion just behind the spinner from below. Three silver tubes running down should be the oil piping connected to the reduction gearbox.\u00a0<\/em><\/em><\/p>\n There are three more shots below showing you the air ducting section placed behind the\u00a0air intake – which was\u00a0removed here. The camera is placed under the exhausts looking toward the tail.<\/em><\/p>\n Let us look at the port side of the engine now. We can start near the propeller continuing backwards.<\/em><\/p>\n a\/ Left-hand (port) side<\/span><\/strong><\/p>\n Camera is looking at the\u00a0spinner \u00a0and the section behind it with the propeller governor on top.<\/p>\n The same place but in closer look (picture below). There should be the propeller governor \u00a0on top and the overspeed governor (black cylinder with silver lever in the middle, below it).\u00a0<\/em>The text on a\u00a0<\/em>sticker is:<\/em>\u00a0Control lever must be safely wired in max RPM position except during ground test.<\/p>\n This is that end of the turboprop engine, where to find the accessory gearbox and connected equipment (lower pictures).<\/em><\/p>\n Here should be the starter drive\u00a0on the picture below (black cylinder) and the ignition exciter box (that silver box with red stickers to the left and a bit down). A small silver cylinder should be the oil filler cap (upper left portion of the picture). The silver rectangular box\u00a0<\/em>\u00a0just to the right should be<\/em>\u00a0the\u00a0fuel heater<\/em>.<\/em><\/p>\n Additional info regarding the engine architecture can be found on this page<\/a>.\u00a0This nice animation<\/a> would show you how the\u00a0Pratt Whitney PT 6A-27 turboprop engine works.<\/p>\n Note:<\/strong> Here you can find my\u00a0previous Pilatus detailing post – PC-6 details Pt.
