Aviation diesels and turbo's
"Calvin R. Walker" wrote:
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... http://innodyn.com/aviation/index_aviation.html Interesting. Looking at the three other aero-diesel manufacturers, it looks like their engines are competitive on both weight and fuel consumption. Zoche aero-diesels.

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. |
