Aerion recently took another step toward reintroducing civil supersonic transportation when it announced in October that it has an engine for its AS2 mach 1.4 business trijet. GE Aviation’s Affinity line of supersonic-capable turbofans will also meet upcoming Stage 5 environmental and noise standards.

GE has built supersonic-capable engines for military applications since the 1950s, for the F-104 Starfighter, and is drawing from that experience for the Affinity turbofans. The new engine features a service ceiling of 60,000 feet and the highest bypass ratio of any supersonic engine.

The first AS2 is scheduled to fly in 2023, with certification in 2025, and GE says that it will have the engine ready to support that schedule.
