787 Dreamliner
The Engines, Rudder, and Flaps
There are revolutionary designs to the 787's components. Firstly, all airplanes are in the risk of ice forming on the wing, causing the aircraft to have limited lift. The 787 has built in wing heating, warming the wing so ice has a less chance of forming. Also, a revolutionary design that makes this aircraft ahead of many others, the 787 has a special wing curve. At the tip of the wing, there is a special curve that solves a problem of drag forming on the tip of the wing. The 787 uses the world's most efficient engines: The Rolls-Royce Trent 1000 and the GEnx engine. New fans in the engines reduces the "buzzing" noise other passengers have complained about. If you were to encounter a flying 787, you wouldn't even notice it was an airplane because it's engines are much more quieter! A feature in this airplane, there is a cross feed function. This is where a pipe transfers fuel from wing to another, just in case one wing is losing fuel. The airplane engine's heat is used for the wing heating feature, and the air is used for air conditioning and pressurisation. They consume 20% less fuel than jets such as the 767, 777, and A330! The airplane can fly up to a speed of mach 0.85, or 1050 kilometres per hour!
This is how an airplane engine works:
The air is first sucked into the engine. Tens of turbines compress the air, which makes it highly flammable! It is mixed with fuel, then ignited at the back of the engine. But only one-tenth of the air sucked in enters the compression process. Since the air inside it is extremely hot, and outside the compression chamber is much colder, the temperature difference helps cool the engine, and also helps create thrust. Plus, it makes it more quiet! The air that is compressed becomes one fifteenth of it's original volume, and the air can reach temperatures of up to 2300 degrees Celsius!
