Unpublished photos have been unveiled by NASA where we see two planes crossing the sound barrier, at more than 1,225 km / h.
NASA was able to capture the first images of the interaction of shock waves from two supersonic planes flying in formation. These two US Air Force T-38 planes flew at a distance of only nine meters from each other. By exceeding the speed of sound (which is approximately 1,225 km / h), an aircraft creates shock waves that are heard on the ground as a supersonic detonation.
The photos were taken from a third plane using high performance equipment, explains the US space agency on its website. ” One of the biggest challenges of the flight series was the timing », We can read.
The purpose of these flights is to raise awareness of the characteristics of shock waves. So, thanks to these silent supersonic research flights, civil aviation could benefit, and commercial supersonic airplanes could make a comeback.
