If you stuck a nose on a truck like a bullet train, would it be more aero dynamic?
>>14703444
If by more aerodynamic you mean less drag, yes.
Probably would violate some safety codes
>>14703444
You'd save gas.
American trucks save so much more fuel than faggy Euro trucks because uros need cab-over designs because faggy Europe.
But it's not the front end that's the biggest problem.
>>14703477
Well. What is it then?
>>14703444
The air leaving the trailer has more affect than the nose.
>>14703496
>posts marketing image
not trying to /pol/ but come on.
>>14703499
Prove it wrong
International Lonestars are kinda what your looking for.
What virtual wind tunnels don't account for is that these trucks arent a brick front end, there are openings for wind to enter the the grill and pass through the radiator ect
btw grain of salt and whatnot.
>>14703516
That's not my job. Regardless i'm not arguing with you but it's the same with like how RT non-stop writes about the glories of Russia.

>>14703516

>>14703496
It's basically like an artillery shell. They have a trail behind it which made the shell less effective.
A man found a way around this by putting a gas chamber that would fire gas out and fill that pocket.
The effect was a better shell instead of a better gun.
He was later killed, They think it was Israel.
>>14703499

>but an accurate one because the product in question is actually effective?
It doesn't matter how can i, as a consumer, know it's the truth without unbiased facts. Whether or not there is bias there is no credibility because marketing.
Here's a question to ask yourself any time you are presented with ideas:
>Is someone making money from this?
>>14703526
Then don't bother posting if you can't come up with a decent counterargument.
>>14703444
Kinda. This truck was capable of 11mpg fully loaded. Most trucks now only do 6 or 7.
>>14703540
Do you think they will gain anything if they lie about a basic wind tunnel test?
>>14703540
I bet you think RWD sucks because people say it's amazing and manufacturers used to produce FE/RWD vehicles at a profit.
>>14703576
do you just spew shit onto your keyboard and hope it makes sense?
do you speak in memes?
are you 17?
>>14703499
I took a fluids class in college
He is correct. Those things behind the truck are called Eddie's. To reduce the eddy effect, you put a cone like he is showing
>>14703547
Nope.
>>14703573
>Do you think they will gain anything if they lie about a basic wind tunnel test?
Yes.
>>14703576
RWD does suck in certain applications like snow and rally.
apology for poor english
where were you when western star was build a truck that was boxy also very aerodynamic?
i was sat in truck drinking piss fluid when bubba ring
‘peterbelt is kill’
‘no’
>>14703791
Never seen a Western Star in me loife
>>14703817
That's because fleets only buy throwaway trucks like Internationals and Freightliners. Western Star is pretty much the most premium brand on the market.
>>14703870
May be a Mid-atlantic thing but our fleets are Volvo's and aging Sterlings.
>>14703444
Yes.
>>14703468
But then piss it away with inefficient engines, shit sticking up, sharp corners, etc.
Plus, they don't haul anywhere close to as much weight.
>>14703874
>Sterlings
Have they even made a truck since the rebadged Fords in the 90s?
>>14703882
>Plus, they don't haul anywhere close to as much weight.
Thanks to our vast rail network.
>>14703884
>Have they even made a truck since the rebadged Fords in the 90s?
No. They are now defunct iirc.
>>14703549
Almost looks like a european truck, with all those fairings...
>>14703468
Eurotrucks get similar fuel economy as American trucks though, around 8 MPG, despite weighing 10% more because we engineer more efficient engines than you guys.
>>14703499
it acts the same way as a boat tail bullet.
>>14703896

>>14703918
>97,000 lbs for semis carrying 40' shipping containers here in Germany
Having converted that into proper unit's that's only 44t, standard in the UK, quite a bit (21%) more than the US 36t limit for standard semis. Normal Americunt attitude, do less with more.
>>14704070
no way dood.
>>14703444
I always look at trucks and think how aerodynamically bad they are with all of the flat faces and parts that create more drag and how the owners that own the trucks could save money by spending a little bit on the truck besides chrome everything.
isn't the flat face important for cooling?
http://www.transportenvironment.org/sites/te/files/2015_06_Comparing_US_EU_truck_fuel_economy_explantory_note_Final.pdf
Also do European trucks usually have sleeper cabs?
>>14704103
All trucks, regardless of grill design will have massive radiators and good cooling.
>>14704103
Also almost all of them have oil coolers, also they're diesel so getting hot is good for them.
>>14704107
>Also do European trucks usually have sleeper cabs?
Optionally.
>>14704129
I've been wondering how much speed is lost by driving a sleeper cab over a day cab assuming two trucks were similar in every single way besides that.
>>14704136
0m/s
>>14704076
I'd do less with more as well if my national highway network was paved half as thick as it is. Autobahns feature three feet of gravel and sand bedding, meanwhile Americans occasionally slap asphalt straight onto the ground and call it a day.
>>14703444
If you designed the truck sleeker like a bullet train and fixed up the hard edges on trailers I imagine youd save a lot of gas.
>>14704065
>Stop being a cunt. The ad directs people to their products alone. They are making money from that science.
Because they developed the product through engineering and science. Jesus christ man, stop being such a fucking idiot.

>>14703499
Only a /pol/ user is stupid enough to not know how drag works.
>>14704199

>>14704194
Not building roads right in the first place, do some research and you will see that extra road wear was examined as a potential issue prior to setting the standard 44t limit. It was found to be a none issue.
Wow a whopping 1m miles, the average HGV will do 108,000 a year in the UK and the average age is according to the DVLA 7 years (that's average age so for every new HGV registered in a year there is one that is 14 years old still going) so that would be an expected average of a little over 1.5 million miles travelled by a euro truck. Poo Americunt dashed by the facts again.

Oregon and Washington state allow 105,500lb combinations with 8 axle configurations, or roughly 47.85 tonnes. There's an absolute shitton of carriers doing this here.
Most of them haul containers, although a lot of them are flatbeds hauling lumber and building materials. My truck at work hauls 62,500lbs as a single unit vehicle (28ish tonnes), and 80k as a combo because our 35' trailers are cocksucking 12 ton pieces of trash. If we had a 4-axle trailer I could legally haul 102,000lbs (46 tonnes) if we changed the permits.
Not all of 'merica is created equal in terms of trucking.
Also, on the original topic, my truck gets 5-5.5mpg on a good day. Fucking suck it.

Yeah for supersonic speeds maybe. The Concorde is so unaerodynamic and makes so little lift on its own that it'd fall right out of the sky if its engines failed. Compare a regular airliner still being able to glide around for a few hundred kilometers if all the engines flamed out. Please understandu, air travel is an entirely different beast than ground travel.
>>14707598
Wrong, total permissible weight on American interstates without an extra permit is 80,000 lbs or 36 tons.
Also Kenworth and Peterbilt interiors are utterly overrated crap full of cheap looking grey plastic and muh grey diamond leather. The only really neat interior besides Western Stars is found on high end Coronados.
>>14709270
tons =\= tonnes
1 ton is 2,000 lbs
1 tonne is 1000 kg or about 2205 lbs
40 tons is about the same as 36 tonnes
>>14709277
No one uses short tons outside of Murrika. In the rest of the world a ton is 1000 kilos.
>>14709281
Neato, but we're talking about American interstate limits among a group of primarily American truckers, not about regulations for wherever the fuck you park your high horse.
>>14709296
Use lbs then.
>>14707304
This guy gets it.
Even if it could do without flow through the radiator you would still end up with the same frontal area which will calculate the same cd. Frontal area and turbulence from flow separation are the largest contributors to drag.

Walmart claims WAVE is 20% more aerodynamic than an average rig. It's has a novelty turbine powered hybrid drivetrain though, ICE would probably be unfeasible with that shape.
>>14711848
No reason am ICE couldn't work. Might have to make the chassis section a bit taller, though. 2' clearance above the frame rail is feasible.
>>14709773
$12,000 for an in-frame rebuild vs $120,000 for a new truck. Parts for a rebuild can run under $3000, so if you've got the tools and a spare 30-60 hours you can rebuild it yourself for less than you'd earn in a week.

This.
There are no regs to the length of the truck itself, but I'm pretty sure that every state has regs for combo lengths. Adding an extended nose would make the combo illegal even though the bare truck would still be legal itself. But whats the point of having a big rig if you can't haul shit?

There is effectively no combination length restriction. It's technically 68' off of STAA highways, but even with a 48' trailer my rig is 68'8". There is no restriction on tractor length, however trailers are limited to 53'.
>>14703444
You mean like this abomination? Got 13mpg but the nose swing makes it useless day to day. It was only used for one load then was sold.
>>14703896
It probably has more to do with how you never drive over 55mph.
>>14704103
Not really. Portrait radiators/CAC are just the norm because they're the cheapest configuration and trucks have been designed around that shape for over 100 years. They're not much taller than the engine, though, so the benefits of a redesign would be marginal.

I've had a look at length limits recently because of a hypothetical motorhome tow combination and on state level they make absolutely no sense. Tons of states where combinations are limited to 65' or 60' when any semi will easily reach 70', if not more. If the limits are meant to make sense, why aren't they enforced, and if they don't make sense and aren't enforced, why do they exist?

0.04mpg, maybe. Most of the economy gains in that truck were due to the driver hypermiling abs dicking about around 50mph cross country.

You can run 60' beams without a permit with a frame like that.

I've seen about a dozen. They can't fit modern motors into them, so they're only for owners that wanted a 10+ year old engine to begin with.

STAA highways vs state highways.

Lower valence, box nose, lowering the front end, driving slower, matching the injectors, etc.
>>14722999
55-57mph is doable.

The trailers are legal and that's all that matters.

STAA regulations override local regulations, which don't apply most of the time between an STAA route and a shipper/receiver. For local routes to have precedence above STAA routes they have to do enough paperwork that it's easier to just build to STAA regulations.

The roads are fine. Deal with it.

Portrait radiators aren't necessary, they're just the cheapest option.

Dumbass, the fact that's it's tuned for high speed aerodynamics is the reason it's go poor glide ability. You need long, straight wings for glide ability. If you want aerodynamics and speed, you need highly swept back wings, which don't generate as much lift and have much higher minimum speeds.
A 747 will fucking shatter if you hit the sound barrier with it because it's not aerodynamic enough, even though it can glide much better than the Concorde.
The Space Shuttle glides like a brick taped to a paper airplane, but it's the fastest aircraft in existence. There's no coincidence it's got the same wing as the Concorde.
The pic related EcoRunner V is the most aerodynamic 'car' in existence, and it and the truck are pretty similar in design.

hey trucker, how ya been man!
