Default Aviation diesels and turbo's

Yes, I think there is a future for diesels. My main (and probably only)
concern is the weight of a diesel versus a standard light-fuel burning
IC av-engine. When the weight of a diesel is comparable to a standard
IC engine, then you'll have a hum-dinger.

Check this turboprop out...


Looking at the three other aero-diesel manufacturers, it looks like their
engines are competitive on both weight and fuel consumption.

Zoche aero-diesels. (air-cooled)

Centurion Engines (liquid cooled)

DeltaHawk (liquid cooled)

Let me do a simple question (to gratify my curiosity). I got the basic
idea that you need to measure one quantity for each parameter you want
to control. Let's say, for a turboshaft fuel contro unit you keep under
control the power turbine speed and act on the unique parameter you can
influence, fuel injected. Other quantity controlled are just to prevent
limits excedances (TOT, Toprque, N1, ....).

Now, in the case of the "adaptive-timing ignition system", what will it
keep under control?

On a turbine engine, turbine inlet temp is the most important parameter
followed by power turbine rpm.
