Tfw you can explain most aspects of auto engineering to people and teach them how cars work

the reason it fucks with your head is because you are just one person.
that system was not designed by one person.
it's like brainstorming - it makes your brain work in a different way that you can not do on your own

i'm talking more about the math and the understanding of physical principles that went behind this

that's what blows my mind

Retard.

I started my degree at 25.
I got a shit job after graduation as a technician running development engines on an engine dyno. Did that for 18 months. And now, less than 5 years after I started my degree I work as an engineer specialising in engine performance and emissions calibration and get paid over 100% more than the job I was working before I started the degree.

Get back into college you absolute fucking faggot.

>impossible design
>R/C car motors spin up to and over 100,000 rpm

and turbine shafts regularly spin to over 150k in production vehicles erry day.

>can't even begin to wrap your head around how they came up with such a system much less figured out all the angles and the metallurgy and the sizing and the electrical stuff and everything else
it takes allot of people allot of money and time

think of it like farming
like how china has such a large population that when they want to train athletes there is a huge pool of people with the right attributes

and you have enough money at hand to train this group of people from like 10 yo or some shit
so even if five of them fail to make the grade you have another 5 that almost by chance alone are better

I need to move out first I cant take living at home.

maybe Ill go to school when Im on my own.

Well then it sounds like you need to take more math and engineering courses or you just aren't very smart.

>allot

verb (used with object), allotted, allotting.
1.
to divide or distribute by share or portion; distribute or parcel out; apportion:
to allot the available farmland among the settlers.
2.
to appropriate for a special purpose:
to allot money for a park.
3.
to assign as a portion; set apart; dedicate.

Neato and congrats on the job, but its possible to get into engineering field without the degree. I think youre the retard sir.

Stop procrastinating. Stop making excuses. That is the biggest reason for people failing their dreams. Just do it.

...

oh please go on wizard of all that is mathematical and mechanical. please divulge your secrets as you talk down to me. jackass

splitting up the turbo and compressor was really fucking clever.

what you need is collins decimal gem reckoner
or really any of the older books
outside of cfd the fundamentals have not really changed
and all the newer information is behind an iron pay wall that will get you thrown in prison and indebted for life if you touch it without the fee

Im not procrastinating Im working to save money to move out so I could go to school.

but at the same time Im continuing my education (outside of school)

thank you so much lad.

???????????

That neat marketing video simply boils down to:

>"we lengthened the turbo shaft and put a generator on it."

>chatting with a guy at the bar last night
>he's an engineering teacher
>his son went back to school at 26 for computer engineering
>graduated at 30
>hired right out of school for a $90k/year job with a $10k hiring bonus and the potential to make $115k/year in 6 months

fucking right

Hey you got the turbo handbook by the other (wrong) Mr Bell

you're missing the part where they have won 46 races out of 53 since the v6 came into play, with a clean sheet design on untested technology

that's pretty fucking crazy

And what does he do at his job exactly? No one ever talks about this.

thats fair, but its not some kind of OMFG SO COMPLEX shit.

I'm sure they did plenty of testing before the races.

he engineers computers, avi

he does coding for a large company. exactly what sort of coding he didn't say

but he went on to tell me that pretty much all of his buddies who left the same university (clemson univ in upstate south carolina) are being drafted right out of school for $50k+ per year

doesn't seem impressive

especially for a team of engineers working for a large company

Of course.
But its not as easy at it was 20 years ago when you could work your way up the ranks in a single company. A lot of the old boys in the engineering department I'm in managed to do this.
However in this day and age HR will pretty much require a degree for any kind of 'management' or office position. The guys on the shop floor have almost no chance of getting a job in the office.
Every new hire in the last 10 or so years have been graduates. You can quite literally walk into an engineering job if you have a degree.

ITT: Armchair engineers

Mercedes has completely dominated the past three years and they don't even have the best drivers. That engine is one of the top five engines of all time. Also OP, go to a good university and they'll teach you all of that stuff over the course of a master's degree.

no, that engine is a pretty normal engine. the benefits that resulted from seperating the turbo intake/exhaust housings is what made Mercedes dominate. cooler intake temps, lower exhaust temps, tranny can be pushed closer to the center of the car for better weight distribution and a bunch of other shit I can't remember, simply because they stuck a longer rod between the turbo housings.

Pretty normal my ass. The hybrid system is excellent, the engine is reliable, the turbo provides plenty of power, and it is overall just a very clever idea. Look at McLaren Honda. They have just as many brilliant men in a room and they can't make their power unit work for shit. We'll be talking about this era of Formula 1 just like we talk about Schumacher's dominance with Ferrari

I've mostly been doing kinematics as its an easy starting point
but I figure once I'm though that I might get into fluid and thermal dynamics
with the end goal of being able to put theory into practice with a higher success rate

Materials Science is the real boogie man that I feel ill never get to grips with
A for Alexander ?

They didn't come up with it all at once. They had a design brief they wanted to meet, and had small breakthroughs after long periods of headscratching each step of the way.

That looks inaccurate. Unless it's a rough outline.

>thermal dynamics

is that the same thing as thermodynamics?

mate

I renember reading that the turbo speed was very limited by regulations, but can't find the link so whatever.

In any case, the generator is also used to control the turbo speed. Since you can use the motor to boost, you don't need to worry about turbo lag and can use an oversized compressor.
It's clever technology, but the speed and heat that the motor runs at means you're better just using a normal turbo + separate electrical compressor on a road car, it saves you all the extra engineering associated with mounting the motor on the turbo shaft.

It's an old idea, but requires a lot if engineering to get it to work.

Mercedes' real genius was on nounting the compressor on the opposite side of the engine to the turbine. It reduced the heat soak from the turbine you normally get, let them mount the compressor nesr the airbox, simplified all the piping and reduced the size of the intercoolers, letting them package the rear of the car much more tightly. I think everyone will have copied that system by now though

The ironic thing about McLaren Honda is that their turbo is made by the same company as the Mercedes. Albeit it's their Japanese rather than German division, and the German division was only a technical partner on the Mercedes project, with Mercedes doing the manufacturing themselves.

McLaren wanted to put the compressor inside the Vee, and as a result, undersized it. If they'd been less picky about packaging, it wouldn't have happened.

i'm a senior mechanical engineering student who's been interning with a company for the past 4 months. the deal with projects of this size is that it never boils down to just one guy, or even a small team of guys. stuff like this comes from the work of a lot of folks with various areas of expertise.

the undergraduate degree prepares you to be a lifelong learner with a foundation on the basics. actual industry tools and research and development are usually relegated to folks with graduate degrees.

The powertrain lives and dies pretty quick, probably less than 80 hours on any one engine or transmission part

But rc cars don't make 900+ hp to the wheels

As an engineer, it's very, very hard to secure a real engineering job without a degree. The best most people get without a degree is a technician or technologist.

dunno abou the other guy but i can engineer a degree out of thin air

this. Mercedes was years ahead of the game compared to the other teams. Preparation and opportunity is the perfect recipe for success.

I'm currently studying to be an aerospace engineering and this stuff is simple compared to rocket propulsion and flow dynamics.

The biggest thing with most of these engineering concepts are how terribly they are explained. Engineers are terrible at explaining their ideas.

The idea is to simply the entire concept down and then build up from there.

My car ignorant friend wanted me to explain turbos to him and how they work. I started out by explaining how a fire works, with fuel, heat, and oxygen. Then proceeded to explain how an engine utilizes all three, and how fuel and oxygen basically determine how large of a fire you can get.
Then I went into compression of gasses and how that increased oxygen which meant you could also increase fuel for bigger bang. He understood it all. But if I hadn't started with the whole fire concept and built it up he would have had no idea.

on the first Smart (yeah I know) the turbocharger shaft spins up to 250k rpm

50% thermal efficiency for a (relatively low compression) gas engine is quite impressive, don't you think? Considering freight ships achieve about 55% with way more compression and way more focus on efficiency. What do your pesky rocket engines achieve? 15%, 20%?

smaller turbos spin faster. an F1 turbo is huge compared to the smart car and cant spin to 250k because of aerodynamics

Absolutely. Of course diesel engines in general are known for being almost twice as efficient as their gas counterparts. 50% is a very impressive thermal efficency for a gas engine.

Turboprop engines are actually very efficient, while the rocket engine is terrible. It's difficult getting shit to move when you have nothing outside of your system to use as fuel haha.

Next generation spacecraft will be looking toward other methods of propulsion as rocket propulsion cannot generate high enough speeds to make even a Mars mission feasible in a reasonable amount of time. You'll be seeing more research in particle acceleration. As there is shit in space to push against, just not much of it. The benefit of being able to push against these particles is a perfectly constant rate of acceleration which would be a slow start but reaching incredible high speeds would be very feasible for interplanetary travel.

Intergalactic travel will be accomplished by fusion engines like used in star trek. They are very plausible and are gaining credibility as there is now proof that space can be manipulated. Google star trek fusion impulse engine.
