Question

Briefly list and discuss all of the structural components, and layout, found in the fuselage of a Boeing 747-300/400. Including, but not limited to, cockpit, hatches, doors, or other openings, and any ancillary components (eg landing gear, undercarriage).

Answer 1

Aircrafts experienced less difficulty filling seats, and in reality needed greater limit with regards to essential whole deal courses. Boeing considered extending the 747, yet chose rather to broaden the upper deck by 7.1 meters (23 feet 4 inches), with the extended upper deck expanding traveler topside facilities taking all things together economy setup from 32 to 91 travelers, six side by side with a solitary walkway; supplanting the first winding staircase to the upper deck with a straight staircase additionally arranged for space on the fundamental deck for seven more economy seats. The extended upper deck could likewise oblige 26 sleeper situates in a top notch setup. The SUD highlighted a crisis exit on the two sides; most likely travelers riding an inflatable slide from that stature discovered it an energizing background. Some noteworthy features in Boeing 747-400:

• Refreshed turbofan motors - the new P&W PW4056, or the most recent variations of the CF6 and RB211, in the push scope of 258 kN (26,300 kgp/58,000 lbf) in addition to - alongside another Pratt and Whitney Canada (PWC) APU, supplanting the more seasoned Garrett unit. Qualifying every one of the three kinds of turbofan motors at the start ended up being a noteworthy cerebral pain.
• Utilization of composite materials and propelled aluminum compounds to spare airframe weight..
• A 1.8 meter (6 foot) extend of each wing, with composite "winglets" 1.8 meters (6 feet) tall at the closures to decrease "vortex drag" around the wingtips, bringing about more proficient journey.
• Another computerized flight deck AKA "Electronic Flight Instrumentation System (EFIS)" with six CRT shows, got from take a shot at the 757/767 jetliners, to allow two-team task.
• Fuel tanks in the tailplane; in addition to a modularized floor design conspire, with galleys, toilets, and seat game plans effortlessly migrated according to client demand.

Other than this,all features were same as Boeing 747-200. In fact it was claimed that some 747-200 models were re-painted and sold as 747-300/400. So, specifications were as follows:

• Alongside the new motors and different changes, the 747-200B likewise highlighted a greater focus wing segment fuel tank, giving around 9% more prominent fuel limit, for an aggregate of 194,680 liters (51,430 US gallons).

• The shorter fuselage influenced parallel strength, so the 747SP was given a taller tailfin; tailplane traverse was likewise expanded, and the triple opened folds were exchanged for single opened folds - the 747SP being the main 747 variation that didn't have different opened folds. Traveler limit was up to 360 seats, however 305 was more sensible; there were four entryways on each side rather than five. Fuel limit was the same concerning the 747-100. Range was expanded by around 9%.

• Enhancements in motor innovation and the more noteworthy fuel limit of the 747-200 made the 747SP excess, thus just 45 747SP machines were sold. Be that as it may, those that were sold were held in benefit for quite a while and had a decent resale esteem, so it shows up the 747SP functioned admirably enough in its specialty.
