More on efficiency and vibration.
From my memory - vw/fiat have simple 1.9 turbo diessl engine. Which was in 80-90 hp range. And was perfect with single mass flywhell.
But - after tdi/jtd come to market and power...
Which is still ok for our 40-44" wide cocpit.
And 19" is total engine height. I think more than few iinch could be shawed of by making flat head cover. Old one is a breather too and have to be changed..
I do not like myself. But - it is possible, new market "situation" for uav will create some interesting diesels. And the most interesting ones, looks to be two stroke with extra supercharger for scavenging..
Definetly. Even if it would need an cross atlantic flight :)
But but - 93 years ago diesels was even better without turbo Packard DR-980 - Wikipedia
By raw simplification and dropping all parts which was not needed :)
There isn't at the current moment / I was not able to find one. It is kind of unicorn - aluminium block with cast iron liners, 8 valves 4 cylinder and low stress. All this equals to low weight. Next one on size list is Fiat 1.2 JTD with cast iron block, Or 1-1.2 liters engine from VW to Huyndai...
Hmmm. It is all a little bit different. I do not have an intension to design totally unique one aircraft. I have set of gazaile plans. If i would build it to gazaile shape +- weight and structural strength - it would be a carbon gasaile.
A performer, good looking and possible to have selable...
As life goes in and my big garage with small metal working lathe become a small garage with big lathes - full molds are big just carry along. Totally agree and thank you for other ideas on how to make that one nice airplane fuselage.
My small idea / extra - in place of curved xps for corner...
Same as mine in first post ?
Its all depends on your mission. For me, diesel with mechanical pump is best in reliability. Maybe harder to start. Maybe with some extra weight.
But, for longer mission if you take into mtow also your fuel - you are in a win win scenario.
