Don’t Forget to Make Them Biodiesel-Compatible!
Most helicopters are powered by turbines. This provides a great power to weight ratio, but it also burns a lot of fuel, which is why Eurocopter is now looking at diesel piston engines as a way to make its choppers more fuel-efficient. We’re talking about significant savings too, on the order of 40%. But before that can happen, even more power needs to be wrung from even smaller diesel engines (as you can imagine, weight reduction is key for an helicopter engine)….
