 Posted: Thu Oct 27, 2011 11:41 pm Post subject: Rotec Liquid Cooled Heads for the Jabiru 3300 |
 |
|
Hi,
This is my first post, I hope it works! I'm posting this to the Europa list rather than the Jabiru engine list because the Jab 3300 getting too hot seems to be a specific Europa problem, even listed on the LAA's approval document as an issue!
Anyway, I have been looking at the ROTEC LCH (Liquid Cooled Heads) and I think this is a really interesting idea, bringing a key feature across from the Rotax engines. They claim that in an hour of ground running at WOT the heads only hit 200 degrees!
Here's the link:
http://www.rotecaerosport.com/product-info/lch/
I'm posting on here not to spark a "Jabiru vs Rotax" debate, we all know how that debate goes, I'm simply looking for people's thoughts on this idea. Technical and otherwise.
My other particular line of enquiry is how likely this is to get Prototype Modification Approval with the LAA, how onerous this will be, how much down time the aircraft is likely to have as a result.
Regards,
-Carl.

Hi,
Best to check this with LAA. I have checked and it seems to be a dead end. Some thing to do with Jabiru not allowing the engine to be seen as a new type in the UK.

That's a shame Tony,
seems to me it's the sensible thing to do with a Jab. Or a Lycoming if it comes to that! {{;-<

I will give Andy Draper at the LAA a call, perhaps he already reads this list.
It would be a shame if Jabiru were to block this from happening, I'm a big Jabiru engine fan…. In concept… but the poor thing has struggled with temperature issues throughout it's life. I'd love to climb to 5,000ft full power without it cooking! I have little doubt water cooled heads would improve reliability, reduce risk of valves dropping, and improve probability of hitting TBO.
If there is no way to put innovations like this forward, with all the proper controls and checks, the UK would be missing out – and that's a shame.

Looks like an elegant solution to well documented problem. The only potential problem I can see (and the LAA might object to) is that it uses an electic water pump and this makes it dependant on the electrical system. With a belt driven mechanical water pump (automotive practice) this could work.

However they tested this and concluded it cooled without water pump no worse than the factory heads. Sounds good to me!
