Sonic Boom of Futuristic Biplane- Not a Boon

Sonic Boom of Futuristic Biplane- Not a Boon

Stanford University and MIT researchers are now saying that some elements of aviation from the start of the 20th century might actually hold the key to effectively eliminate sonic boom. Biplanes are still in use today and the concept of supersonic aircraft that the researchers are now working on is very similar to these. They have introduced a 2nd wing, which they are saying cancels all the shockwaves that have been generated by any objects that are close to or beyond the existing sound barrier.

The Sonic Boom Concept

The fact of the matter is that this is not really a new idea at all. Adolf Busemann, the aviation pioneer had suggested this idea way back in 1930. Incidentally, he was also the one responsible for the concept of the>swept-wing aircraft. Any aircraft that travels at supersonic speeds will end up causing shockwaves in the surrounding air. The very rapid air compression at towards the front of the airplane is what causes the 1st boom. The negative air pressure that gets left behind in the wake of the airplane causes the 2nd boom.

Harming the Environment

These two booms are entirely separate phenomena. However, since they actually occur in quick succession, they seem like one single sound. Any aircraft that is in supersonic flight emits continuous booms as it speeds through the sky. All of this might sound good and adds to all the drama at any air show, but in regular use, the novelty simply tends to wear off.

In addition, there is the issue of the negative impact it has on wildlife- this could be injury or shock in the short term. Over time, wildlife might also abandon that entire habitat. Thus, it really isn’t a surprise that some factions do not consider supersonic flight for commercial uses a very beneficial change.
