Quiet Supersonic Flight
The Spike S-512 Supersonic Jet will be the first aircraft aerodynamically designed to offer Quiet Supersonic Flight. This will enable it to operate at its full cruising speed of Mach 1.6 (1100 mph) without producing a loud disturbing sonic boom on the ground.
In fact, the Spike S-512 is the only supersonic jet, in active development, that will fly at Mach 1.6 supersonic speeds to any city without disruptive sonic booms that are prohibited globally.
Without doubt, a customer purchasing an aircraft for $100m+ expects to take full advantage of the maximum supersonic speed and time savings without compromise. By design, the Spike S-512 Supersonic Jet does not have that limitation. It is for travelers that need to get to their destinations faster, whether over land or water.
Spike Aerospace believes that any successful supersonic program must ensure that the aircraft that can operate at its full speed without producing a sonic boom. The Concorde produced such a tremendous sonic boom noise that it was restricted to flights over transoceanic routes — primarily NYC to London or Paris.
Reducing the noise created by a supersonic jet has been a primary focus at Spike Aerospace and is a significant development resulting from ongoing engineering efforts. Spike S-512 has a sonic signature that is expected to be less than 70 PLdb (perceived loudness level) sounding like a soft clap or background noise. This is what we refer to as Quiet Supersonic Flight.
