Can private jets go supersonic?

Today, companies are choosing one of two paths to go beyond the speed of sound: private planes or commercial airliners. Spike Aerospace is on the first path: private supersonic jets. Its design has reduced the sonic boom to the sound of a car door slamming.

Why jet engine produces so much noise?

Jet engines produce noise in different ways, but mainly it comes from the high-speed exhaust stream that leaves the nozzle at the rear of the engine. And planes are loudest when they move slowly, such as at takeoff or at landing. The turbulence produced from this instability becomes the roar of the engine.

What is jetjet noise reduction technology?

Jet noise reduction technology also has application in the design of highperformance tactical aircraft. Jet noise is of particular concern on aircraft carriers where it is necessary for deck crew to be in relatively close proximity to the aircraft at takeoff and landing.

Is supersonic jet noise of particular concern on aircraft carriers?

Jet noise is of particular concern on aircraft carriers where it is necessary for deck crew to be in relatively close proximity to the aircraft at takeoff and landing. In this paper, a brief discussion about supersonic jet noise sources and a review of the main passive technologies employed for the reduction of supersonic jet noise are presented.

Why do jet planes make so much noise?

The large velocity ratio and the presence of Shocks in the exhaust plume from low bypass engines or supersonic jetliners cause jet noise to be dominant component of overall aircraft noise, and therefore is an important issue in design of the next generation of civil supersonic transport.

What does a supersonic crack sound like?

Having said that, the decibel level doesn’t tell the whole story for a couple of reasons: The supersonic crack is a sharp sound that’s typically less comfortable than the ‘thud’ of a suppressed round.
