Aerion is well into laying out its “technology roadmap” for reintroducing civil supersonic transportation via its AS2 Mach 1.4 business trijet, announcing the first supersonic engine in 55 years on Monday at NBAA 2018. Dubbed the Affinity engine, the supersonic-capable GE Aviation (Booth 244) powerplant will also meet upcoming Stage 5 environmental and noise standards. Separately, Aerion further announced the AS2's avionics suite—a Honeywell Primus Epic package.
