Cirrus Design Corp's "Jet" has flown on July 3rd.

The first aircraft, N280CJ dubbed "V1" took off for the first time at 10AM central from Duluth International Airport for a 45 minute test flight.

Duluth, Minn. (7/3/2008)
Cirrus Design Corporation announced that the most highly anticipated aircraft in the company's history, currently called 'The-Jet', made its first flight at approximately 10 AM CDT today, July 3rd, 2008. The 45-minute flight was conducted from company worldwide headquarters at the Duluth International Airport, Duluth, MN and the aircraft performed flawlessly.

Congrats to Cirrus Design on achieving first flight!  champagne  She looks beautiful!

One question, what kind of parachute modifications had to be made to this aircraft's CAPS in light of the fact that it is to cruise at about 300kts? The SR20 and SR22 systems require the pilot to slow to below 130KIAS before CAPS deployment.

One thing I also wonder, what will be the final designation of this aircraft? A Cirrus engineer who visited my campus stated that the name wouldn't remain "The Jet" forever.



Enjoy!

Did I hear it correctly on that video? This jet has vectored thrust?


Read this very carefully, I shall write this only once!

What are the ramifications of mounting the engine in that way? I understand it's basically the only feasible way of creating a single-engine jet, but surely mounting that engine so far forward (presumably for CoG concerns) must introduce serious heat questions for the tail area? Apart from the painting aspects, doesn't having extremely hot air blasted over the top of the fuselage affect the fatigue life of the fuselage?


I'm tired of the A vs. B sniping. Neither make planes that shed wings randomly!

What they mean is that the engine's thrust is vectored level. The reason is that the engine is mounted on the top rear of the fuse and thus requires ducting to straighten the thrust line.

Good question. This is the main reason for the V-tail configuration. As far as fatigue life I can't imagine it'd be any worse than any other tail mounted config. Eclipse has already done multiple test flights of this type of arrangement with the EA400. It will also depend on the material composition of the tail components and CFD analysis verifying where the engine exhaust goes and at what temperature.
