Green Jet Today, Bluer Skies Tomorrow

We built the Eclipse Twin-Engine Jet with an eye to the environment. The plane is assembled using friction stir-welding, a green manufacturing process that produces no fumes. It’s engine fire suppression system, PhostrEx is the first Halon alternative agent to be approved by the EPA and FAA in more than 50 years, and conforms to international treaties protecting the earth’s atmosphere. We also considered noise pollution, both inside and outside of the cabin: the Eclipse Jet is a full 40 dB quieter than the world’s most stringent Stage 4 noise requirements, meaning you can have comfortable conversation while landing at airports which restrict aircraft based on engine noise.

Friction Stir Welding

Friction Stir Welding

Eclipse Aerospace pioneered the use of friction stir welding (FSW) in aircraft structures, using it extensively in the primary structure of the Eclipse Jet since receiving FAA approval in 2002. At 20 inches per minute, friction stir welding is approximately 10 times faster than manual riveting and provides a continuous join for improved structural rigidity. Friction stir welding patterns are computer-controlled to ensure accuracy, virtually eliminating time-consuming rework. The resulting airframe structures are stronger and lighter than those built using traditional processes. This is one of the key processes that allows the Eclipse Jet to be the most fuel-efficient twin-engine jet on the planet.

PhostrEx™

Eclipse Aerospace developed the first new engine fire suppression system in 50 years, PhostrEx. Used exclusively on the Eclipse Jet, PhostrEx is the only non-Halon engine fire suppression system approved by the Environmental Protection Agency and Federal Aviation Administration and is the first new engine fire suppression system to be approved since 1954. The result of these dual approvals is that PhostrEx is the only fire suppression system today that can meet the standards of the Montreal Protocol, an international treaty designed to protect the depletion of the earth's ozone layer. Until now, aircraft were exempt from the treaty and allowed to use Halon. That is, until a suitable replacement was available. That replacement is the PhostrEx fire suppression system.
