Reducing Noise and Emissions at Supersonic Speeds

Supersonic aircraft are returning to development in an era of far stricter environmental regulation. All modern commercial jets must comply with ICAO Chapter 14 and FAA Stage 5 noise standards. These are regulations that didn’t exist during Concorde’s time that require reducing supersonic noise and emissions. Emissions limits, especially on NOx and CO₂, have also become significantly more demanding.

Spike Aerospace is addressing these challenges at every level of design. Noise levels during takeoff and landing are being reduced through improved nacelle acoustics, shaped engine nozzles, and advanced combustor designs. Emissions are tackled through more efficient burn profiles and emerging fuel technologies, including compatibility with Sustainable Aviation Fuel (SAF).

By designing the Spike S-512 Diplomat to meet or exceed today’s noise and emissions standards, the company aims to deliver a supersonic aircraft that is not only fast and efficient, but also regulatory-compliant and airport-friendly. Our goal is reducing noise and emissions at supersonic speeds.
