Anybody know a LongEZ with CD-155
 
Got bored one day and started looking.
Couldn’t find anything useful.
Anybody know of a LongEZ or other experimental with a CD-155 Diesel/JetA engine?

Not that installation, but a piston diesel long-ez project: http://www.longezediesel.com/p/welcome.html

Yeah I found that one but he’s a Redjacket and it’s from 15+ years ago.
Gotta be someone out there with a more recent installation.

This guy might know.

But if I had to guess ... there's not one. High upfront cost certified engines don't tend to be a favorite of homebuilders.

There was some discussion of a Thielert installation in a Cozy some years ago, but I don't think that happened.

There have been a few turbojet Cozy's or Long-EZ's built and flown. https://www.eaa.org/en/airventure/ea...-at-airventure

The Shockwave installation never took off, but also had a few installations, I believe. https://eaa1541.org/members/what-our...ccis-cozy-jet/

The Jetcruiser 450, while not a Rutan design, was a turboprop canard single, with an Rolls Royce engine, later re-imagined with a P&W, and in theory, to be produced in kit form in California. It was to be a production aircraft with Part 23 certification. Presently the certificate owner is looking at going electric.

XCOR corporation had a one-off rocket powered Long-EZ (EZ-Rocket) which was actually piloted by Burt Rutan, using two liquid-fueled rocket motors. https://www.space.com/1834-xcor-rock...cord-book.html

Deltahawk promised a 200 hp diesel engine for a long time, and eventually put some in UAV's, and had an installation in a Cirrus. Their plan from very early-on was to put one in a Velocity, and they did announce an intent to produce an installation for the Cozy MkIV. They were a bit on the pricy side; closer to seventy grand.

The Raptor was a cozy-esque aircraft that did fly using a diesel engine (Audi), and there was some talk of a P2M J3E diesel, but after the prototype crashed in a field during a ferry flight, the project ended. There's a resurrection looking at electric right now, as the Raptor NG. https://youtu.be/hxFxxFAEv18. The Youtube videos show it flying again, with a diesel engine.

There a ducted fan Long-EZ out there, too. The Duckt used a Mazda rotary. Not diesel, but automotive fuel. http://mickaircraft.com/duckt.htm

That one crashed with a fatality.
Nice plane though except for the pods.
A jet Cozy would be pretty outrageous.
Thanks to both JB’s for the info.

I’ve got some time in DA-42’s with 3 different engines, the Thielert 1.7 and 2.0L and the Austro engine.
Despite its early growing pains the 1.7 was my favorite by far.

Dreaming here but I’d be more interested in endurance then speed.
10+ hrs at 150-160 TAS should be feasible with a 155-160hp diesel/JetA installation.
You’ll need Rutan(-ish) aerodynamics to make that work.

I remember going too fast for mission requirements in the Austro and throttling back to 130 indicated, to slow-cruise. 8gph total. Both engines.

I’ve done a non stop 1200 miles in 7:48 airborne time with a total fuel burn of 66 gallons for an average of 155kts/GS and 8.6 gallons/hr on the 1.7L Thielerts.

The Thielerts are, or at least used to be, horrendously unreliable. My good friend manages a club/flight school with quite a few of them, and they have been nothing but trouble. They lost 2 172's already, one for clutch failure, one for a fuel pump failure, and the turnaround time for overhauls is over a year currently.
The Austro doesn't seem much better with constant fadec problems. One of their 172's with is has been grounded for close to a year for lack of parts.
These are high utilization planes though but these engines are clearly not suited for that.
