| Chuck Yeager - First person to fly faster than sound |
The week has flown by like we broke the sound barrier! That means we went from subsonic to supersonic! You can see by the picture that when a plane breaks the sound barrier a lot can happen! I hope you have had a good week, we will be working hard as we look forward to Christmas Break in a few weeks!
THIS WEEK: By now you have recognized that with fractions they just keep building and building. We will continue with dividing fractions and as always simplifying... can I shrink that crazy thing??
CALCULATOR !!! YOU really want to make sure you purchase a calculator that can do fractions, it needs to have an ABC button on it! Trust me you’re going to want a fraction calculator!!
SPACE FACT:
The sound barrier and Supersonic flight
In aerodynamics, the sound barrier (The sound barrier, in aerodynamics, is the point at which an aircraft moves from transonic to supersonic speed) isa physical boundary (like a wall) stopping large objects from becoming supersonic (Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). The term came into use during World War II when a number of aircraft started to encounter the effects of compressibility- being squeezed, and fell out of use in the 1950s when aircraft started to routinely "break" the sound barrier.
At first the exact nature of the wave drag was not well understood. It appeared that there was a huge increase, as it does for a limited range of speeds. With only the limited power of piston engines to drive them, planes could not overcome this rapid increase in drag, and even large increases in power would result in only tiny increases in performance. It appeared that an endless amount of power would be needed to reach supersonic speeds, and thus everyone started talking about the sound barrier and jet engines.
Vehicles that fly at supersonic speeds are flying faster than the speed of sound. The speed of sound is about 768 miles per hour (1,236 kilometers per hour) at sea level. These speeds are referred to by Mach numbers. The Mach number is the ratio of the speed of the aircraft to the speed of sound. Flight that is faster than Mach 1 is supersonic. Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5.
In 1947, Air Force Capt. Charles E. "Chuck" Yeager became the first person to fly an aircraft faster than the speed of sound.
A bullet fired from a gun is an example of an object that flies at supersonic speeds. Military fighter aircraft also fly this fast. The space shuttle orbiter flies at supersonic speeds during portions of its mission.

| The Concorde |
An airplane called the Concorde was the most notable passenger airplane to travel at supersonic speeds. The Concorde's maximum speed was more than twice the speed of sound. It could fly people from London to New York in less than 3 1/2 hours. That is about half the amount of time it would take typical airliners to fly the same distance. The Concorde is no longer in use. It flew for the last time in 2003.
What Is a Sonic Boom?
A sonic boom is a loud, thunder-like noise heard by a person on the ground when an aircraft flies overhead at supersonic speeds. Air reacts like a fluid to supersonic objects. As objects travel through the air, the air molecules are pushed aside with great force. This force forms a shock wave, much like the wave created by the front, or bow, of a boat moving in water.
The shock wave forms a cone of pressurized air. A sharp release of pressure after the buildup of a shock wave is heard as a sonic boom. It is similar to the sharp release of pressure when a pin pops a balloon and makes a loud noise.
NASA is studying and testing devices that could be used on aircraft to lessen the noise and window-rattling effects of supersonic flight.
