Diesel or Petrol engines?

[the lancaster kicks ass]

we get our petrol straight from the company, we get it cheaper that way............

 

[cheddar cheese]

you mean red diesel?

 

[the lancaster kicks ass]

of course not ....................

 

[cheddar cheese]

cos you know its illegal to use red diesel on the road...

 

[the lancaster kicks ass]

ah, not if you're within 10 miles of your land................

In NZ Diesel is still under half the price of petrol per litre.

However, Diesel engines in aircraft, there was the JU 86 and as well this beastie

2-stroke, haha

 

[the lancaster kicks ass]

maximum endurance: 18 hrs

wow, the crew would need to stop before the plane!!!!!

 

[cheddar cheese]

ok if that was a joke it went right over my head...

 

[the lancaster kicks ass]

it wasn't a joke, endurance means how long it can stay in the air, the crew would need to stop before the plane...............

 

[cheddar cheese]

im lost

 

[the lancaster kicks ass]

ok, a plane's endurance is how long it can stay in the air non-stop, this planes endurance is 18 hours, that means it can fly for 18 hours non-stop, the crew however wouldn't have been able to fly for 18, they would have to stop and land of they would fall asleep "at the weel", thus they would have to stop before the plane................

 

[cheddar cheese]

ah...

 

[the lancaster kicks ass]

you still don't get it do you??

 

[cheddar cheese]

yep 8)

 

[the lancaster kicks ass]

back on topic, diesel's better...................

 

[cheddar cheese]

weve already had the arument and agreed that petrol is better for planes whereas the diesel and petrol are pretty much even in the automotive world 8)

 

[plan_D]

Lanc, the crew wouldn't have had to stop, for a start 18 hours would mean 9 hours out and 9 hours coming home, in theory. So, you would either change crew, or they would just fly for 18 hours. You can stay awake for 18 hours quite easily, as on average you stay up 16 hours a day anyway.
The Tu-95 'Bear' had an endurance of over a day if I remember correctly, and some of their missions from Russia to probe British air space lasted over 20 hours.

 

[Lightning Guy]

All of the modern American heavies have demonstrated an ability to fly around the world thanks to airborne refueling. The only limiting factors being crew endurance and oil.

 

[plan_D]

Yes but the endurance of a plane is without air to air. The Tu-95 is still one of the best planes in the world, and is still the fastest turbo-prop aircraft.
