Proven Production Engines

Aerion has teamed with Pratt & Whitney to adapt the latest generation of the proven and ubiquitous JT8D engine for the supersonic business jet. The JT8D to be employed on the SBJ will incorporate recently developed and patented noise suppression technology to achieve Stage 4 noise requirements.

The JT8D-219 has a maximum static thrust of 21,700 pounds, but is derated to 19,600 pounds of thrust for use on the Aerion SBJ, allowing sustained supersonic cruise at speeds up to Mach 1.6 with excellent durability. As a result of extensive analysis by Pratt & Whitney, assuming 60 percent supersonic flight time, initial TBO is projected to be 3,000 hours.

Pratt & Whitney is assisting in engine/airframe integration, applying its considerable knowledge of supersonic design. specifically, the company is assisting in development of inlets, nozzles and nacelles.

Powering one-third of the world’s airliners, the JT8D has logged over a half billion reliable hours giving Aerion high confidence in meeting performance and cost efficiency objectives, while minimizing development cost and risk.
