When a jet exceeds the speed of sound, the air flowing over the fuselage is suddenly compressed due to the effects previously described. The vapour cone is due to flow-induced vaporization. However, the cloud is a separate phenomenon to sonic booms. The famous sonic boom “cloud” that surrounds an aircraft is a physical manifestation of the “breaking” of the sound barrier. In other words, if one were to follow a plane that was travelling at the speed of sound, one would constantly hear sonic booms. As the plane travels, it drags the cumulative air molecules in the vicinity so a person positioned beneath its path would hear the boom. This means that a sonic boom is not a one-off event. This pressure disturbance is called a Mach wave and is the cause of sonic booms. The loud boom is the result of a buildup of air molecules that can no longer travel faster than the plane.

That is, until the sonic boom catches up. When the jet reaches the speed of sound and beyond, it can no longer be heard from any observer in front of the plane. Initially, the engine noises can be heard from a great distance. Imagine standing in front of a plane as it accelerates towards the sound barrier. If the jet were travelling at the speed of sound locally, the air propagates these ripples as quickly as the jet is flying. Colloquially of course, the speed of sound refers to the maximum speed of molecular collisions in air.Ī jet travelling through air produces similar ripples that are elongated further behind as the jet accelerates. When these effects are combined, the maximum speed at which molecules can collide is known as the speed of sound in that medium. This is because the bonds determine the maximum rate at which a water molecule can move when surrounded by other water molecules. The speed at which ripples spread through the water is determined by the intermolecular bonds and the surface tension of the water. Stone skipping produces ripples on the pond’s surface. Ī sonic boom is akin to skipping stones on a pond. Producing a sonic boom was once thought impossible as numerous attempts to penetrate the sound barrier led to broken fuselages and wings. Known in popular culture as a loud boom that occurs when an object exceeds the speed of sound, sonic booms are of great interest to aircraft designers and a source of ire for residents near airports. In honor of the incredible novelty that is supersonic speed, let's take a look at 25 incredible pictures of jets breaking the sound barrier.While few of us have personally heard one, many of us have witnessed a sonic boom’s shockwave surrounding a speeding fighter jet or a bullet. Since that date, the aircraft has only increased in ability and raw speed. The first man to break the barrier was Chuck Yeager, in 1947. The result of this happening is what's called a sonic boom, an incredibly loud noise, and pressure wave. It's a fascinating and special thing, the concept of an object moving faster than sound can. While this is the only plane that can go that fast, there are plenty of jets that are capable of breaking the sound barrier, also known as Mach 1. The fastest official recorded speed for a jet, the Lockheed SR-71 Blackbird, clocked in at a truly surreal 2,193 miles per hour.

Other aviary accomplishments involve untraceable craft, planes that take off vertically, and, the subject of this article, incredible speed. Since that brief flight, however, the close second for wingspan is the incredibly massive Antonov An-225 Mriya, with a wingspan of 88 meters. One of the most voluminous cargo planes goes to the Airbus Beluga. The feats that man has accomplished while in flight is really incredible, they beggar belief, and are truly astounding, especially when they're given even a small amount of thought.įor example, the largest craft to ever fly had a wingspan of almost 300 feet, the Hughes H-4 Hercules. The sheer capability and power of modern day airplane is something that very few people think about, but it is something that is really and truly awe-inspiring.
