8 JETLINE <strong>marvel</strong> I January 2015 Two New Beauties of the sky this year The A350-1000 The 777-9X Comparing the Aircraft The A350-1000 is the largest of 3 models in the A350 family, with 350 seats in a typical three class configuration, with an 8,400 nautical mile range. The A350 features carbon fiber composite structure and wings, and at 53% composites will have slightly more of the aircraft made of this material than the Boeing 787-9, which is 50% composites. It features new technology Trent XWB engines from Rolls Royce with state-of-the art fuel efficiency, advanced aerodynamics, and state of the art systems. The 777-9 is a stretched version of the current 777-300ER with a new engine and new wing, along with other enhancements, to create an updated version of the 777, which delivered its 1,000th example earlier this year. The 777-9X will feature an aluminum alloy fuselage with a carbon fiber composite wing, and new technology GE9X engines that are derived from the GE90 and GEnx families. The wingspan for the 777-9 will be longer than any Boeing aircraft, and will include folding wingtips to enable the aircraft to utilize current gate positions at airports, as otherwise the new model would require gates typically used for A380 operations (which are currently quite limited at congested airports.) The following table compares the two aircraft on several key statistics, based on preliminary data prior to the 777-9X launch: The A350 cabin width is larger than the 787 and smaller than the 777X. The result is that a typical configuration in economy would be 9 abreast at 17 inch seat width for the 787, 9 abreast at 18 inch seat width for the A350, and 10 abreast using 17 inch seat width for the 777. While the 777 is currently offered in 9 and 10 abreast seating, recent orders have trended to 10 abreast seating as airline seek to maximize seat-mile costs.

9 JETLINE <strong>marvel</strong> I January 2015 How do they do it? Stealth operation How Radar Works talks about the basic principles of a radar system. The idea is for the radar antenna to send out a burst of radio energy, which is then reflected back by any object it happens to encounter. The radar antenna measures the time it takes for the reflection to arrive, and with that information can tell how far away the object is .The metal body of an airplane is very good at reflecting radar signals, and this makes it easy to find and track airplanes with radar equipment. The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility: The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment. The airplane can be covered in materials that absorb radar signals. Do you know? Ray-Ban sunglasses: It all began from aviation Most conventional aircraft have a rounded shape. This shape makes them aerodynamic, but it also creates a very efficient radar reflector. The round shape means that no matter where the radar signal hits the plane, some of the signal gets reflected back: A stealth aircraft, on the other hand, is made up of completely flat surfaces and very sharp edges. When a radar signal hits a stealth plane, the signal reflects away at an angle, like this: How Airplane Cabin Pressurization Works Last week the world was treated to an unexpected spectacle – the sight of an airplane cabin with a big hole in it open to the sky. We can imagine that this spectacle was even more unexpected to people who were on the flight. If you saw photos or video of the hole, you may have also been struck by how little there is between “inside” and “outside” in an airplane. There is a piece of plastic headliner on the inside of the plane, some insulation and then a thin aluminum skin on the exterior of the plane. That’s it. It brings up an interesting question – what is going on inside an airplane cabin when it is cruising at 33,000 feet? It turns out that passengers are flying in something that vaguely resembles a space capsule. Let’s take a look at how the space capsule works. The history of Ray Ban starts in 1929 when the company Bausch & Lomb received an order from the US-Air Force for the development and production The air at that altitude and temperature is also extremely dry. The first thing to understand is that people dressed in normal clothing definitely cannot survive at 33,000. This altitude is roughly the equivalent to standing at the summit of Mount Everest. If there were some way you could stick your arm out the window at 33,000 feet, the first thing you would notice is that it is incredibly cold – minus 40 degrees F or colder. The second problem is incredibly low air pressure. The pressure is so low that people would pass out very quickly from lack of oxygen. So how are we able to sit in an airplane’s comfy chairs at 33,000 feet feeling like we are sitting in someone’s living room? In addition, surfaces on a stealth aircraft can be treated so they Absorb radar energy as well. The overall result is that a stealth aircraft like an F-117A can have the radar signature of a small bird rather than an airplane. The only exception is when the plane banks -- there will often be a moment when one of the panels of the plane will perfectly reflect a burst of radar energy back to the antenna. The first thing that has to happen is pressurization. The air at sea level is about 14.7 PSI (pounds per square inch). The pressure at 33,000 feet (roughly 6 miles up) is approximately 4 PSI. Something has to be done to increase the pressure, or people would quickly pass out from lack of oxygen at 4 PSI. Fortunately, the jet engines on the aircraft act like big air compressors. If you take apart a jet engine and look at it, it has four main sections. At the front, where the air is coming in, there is the compressor stage. Blades suck in air and compress it. The fuel is injected into the compressed air and ignited in the combustion stage. The air expands greatly from the heat of combustion, and flows through another set of blades, turning them as it passes through. And then the exhaust gases flow out of the engine to create thrust to keep the airplane in the air.
