The supersonic biplane, which eliminates the sonic booms

Aviakosmcheskie company and NASA studied a lot of options to reduce sonic booms, and most of their ideas were similar: a long, thin pointed nose of the aircraft, designed to reduce noise problems. Research Associates Tohoku Institute are developing a completely different and fantastic retro-futuristic idea: a supersonic biplane, which can completely eliminate the sonic booms. In flight, the aircraft made a series of air waves in front of him. They travel at the speed of sound. And if the plane is flying at a speed less than the speed of sound, these waves are just to the sides, and people in the world can hear the normal noise of an airplane.

Sonic boom occurs when the aircraft begins to move fast enough, and the air waves (and in fact, pressure) are superimposed on each other, forming a single shock wave of sound at the front of the aircraft. This phenomenon causes discomfort as well as people on earth, and for the pilots. And at the same time they get another sonic boom from the back of the plane, which produce low blood pressure. Thus we obtain a double sonic boom.

Mysore - the honorary title of the sky in Japanese - a conceptual invention of an entirely new type of supersonic aircraft from the Institute of Fluid Science at Tohoku. As you can see, this biplane - the type of aircraft - went out of fashion in the 1930s, as the double wings create a high resistance, and achieve high speeds is very difficult. Although this disadvantage can be turned into a virtue: to place the two wings so that the shock waves to extinguish each other, using high and low pressure and reset them both. No shock waves, can be relatively easily achieved supersonic speeds.

In order to reach supersonic speeds, scientists from the Massachusetts Institute of Technology and Stanford University have developed the idea, which uses a smooth surface of the wings combined with the rough edge of the wing to reduce resistance as much as possible. Thus was created by a supersonic biplane, which flies at Mach 5, and spends half the fuel compared with conventional supersonic aircraft. Mach 5 is flying at a speed of 4000 miles per hour and can take a flight from Los Angeles to New York or New York to London in an hour.
