Operational Context
Eclipse 400 ECJ — proposed single-engine personal jet
The Eclipse 400 was announced in 2007 as a larger development of earlier Eclipse designs. It featured a composite fuselage and simplified systems. The aircraft was envisioned for short-range personal travel.
A single turbofan engine producing approximately 3,600 pounds of thrust (16 kN) was planned. Cruise speed was projected near 370 knots (685 km/h). Maximum takeoff weight was expected to exceed 8,000 pounds (3,629 kg).
The ECJ program was discontinued before completion. Market conditions and financial challenges limited progress. The aircraft remains a notable concept in light jet development.
