Diesels
Cran
I am surprised with your firmness on the diesel 'unfitness'.
Does any one have specifique power figures and tendencies ? (Nick gives .66 Kg/Hp for avgas, of 1.5 lbs/HP, I would put diesels at 2.0 lbs/HP)
It seams to me that at least the diesels are catching up. At least in cars they really do.
In aero (wing) Thielert and their new V8 (certified now in the HP-plane) looks impressive.
It still is perhaps 100 lbs too heavy, but I think at full range it can, save almost 100 lbs on fuel, so in my opinion it is getting close. Tax can be a non- issue but lead is not just a tax issue it makes avgass expensive (somebody told me it only takes a few days to make the world production and it is quite expensive to clean the system after a production batch)
