Default Rv10TDI returned to flight

After a VERY LONG year, the task of changing out the prototype TD300 diesel engine for the type certificated SR305 engine is complete.

The factory sent a representative to inspect the installation on Monday and finally on Tuesday…

It came to life…. https://youtu.be/6iXa01u8nqo

First flight was Wednesday…

Short first flight-yes. Several other flights were made after making prop and governor adjustments. An alternative engine mapping was also tested.

More testing to come…

Can't wait for more updates!

I noted that there are a couple of versions of the SR305; are you using the 230 hp or the 260 hp?

Congrats Scott, looking forward to more specs as you fly the new engine.

I'm confused with the nomenclature describing this engine. It's been called so many different things over the years. Have they settled on something finally?

You mention re-mapping. Is this version now FADEC controlled or does it still maintain the mechanical injection it had previously?

Thanks

This is the 230HP SMAAE SR305-230E. The TD-300 prototype was returned to CMI.

I am thankful to my friends at CMI for the chance to start this project. Covid/economy/changes to the production engine/etc. were slowing progress toward the completion of our agreement, a type certificated production engine. 2020 saw SAFRAN sell the SMA line of engines to the Roder Group in Germany (SMA Aero Engines)and I saw an opportunity. Like CMI, they see the potential in the airframe/engine combination that I do. So I switched manufacturers and as I promised with the TD-300, I will provide data once I have the installation adjusted- both the good and bad. Which hopefully won’t be too long.

The MAIN difference between the SR305 and the CD-265/TD-300 is the SR305 has a computer that controls the ground and flight idles, along with max power. It is not a FADEC system,like the CD-155 or Austral 300 on the Twinstar, as there is a mechanical back-up mode. SMA licensed/sold the SR305-1 information to CMI to produce their engine as they saw fit, hence the visible similarity between the two.

Very interesting for sure. Can't wait to read more about it. Besides the specs and performance numbers that everyone wants to know, I'd especially be interested in what's all involved in converting a flying RV-10 with a 540 to this diesel.
