Why does the 757 have its engines slung so far foward of the wing?  Was looking at one tonight at work (UPS), its almost comical looking.  Theres no way that type of mounting could be as strong as a normal configuration.

I haven't a clue.  CMC Airboss might be a better person to ask. I've always been at the manufactering level at Boeing up until 6 years ago, not the design level.

If they hung straight down they would apply torque to the wing because they pull forward with so much force.  

Imagine a 757 stuck in a snow drift.  Ropes are tied from the engine nose cones to tractors that are trying to pull it out.  Imagine how the much torque would be applied if the engines were hung below.  

With the engines far forward, the rope line and a line of force from the engine nose cone to the engine attachment point on the wing is much closer to straight.

This is near the force applied when the engines pull the plane through the air.

Back when I was in flight traning the told em to be careful of 757s since they caused the heaviest Wake turbulence I remember on a XCountry solo to St Thomas for my Long Xcountry I had to land behind one of those that was a puckerer.

whats wrong with it?

i always thought it was a nice looking plane

Doesn't look that drastic....

Bah!! ye of little faith!  I saw those safety cards ! They show a fully intact plane floating level in the water so the crew can assist all of the passengers out those nifty slides.   And don't forget, those seat cushions float too!!

 I just cant stop laughing. Lets design an airplane to crash in the water, but not fly. OK!

I dont know what to think about this.

No it couldnt be weight & balance could it?

Just curious Rip..Yer on the floor no?..you supervisor,QC,or Engineering?

The topic initially struck me as pretty funny, as I thought it was like asking a high school girl working at Burger King taking your order what she thought about Phase 1 industrial kitchen upgrades used in fast food restaurants and how they improve efficiency or labor costs.  But anywho…

Not sure about the water landing thing, I do know they are designed to break off if they say ingest something and make a fan so imbalanced it would try to take the wing off instead. I don’t know the actual reason for its exact placement, but I’m guessing it has something to do with what Eskimo said ala design and thrust, and I’m thinking it sure is a bonus for maintenance.

 It would be a real pain in the bellybutton to have to remove the fan cowls every time you have to service the engine, or replace a part, as they couldn’t be opened very far if they were under a wing.

Started as an overhead shaper operater, then went through the tool makers apprenticeship program, became a toolmaker. From there I went into NC Programming, and eventually to where I am now, Engineering Applications Analyst.(Big name for what is basically a Project Manager in software)

So you went from line worker,through apprenticeship training and landed management job?..Nice going..!

You suckhole..!

Project Management is typically a different culture from the real world PM, here we have a supervisor to report to, but rarely see them, and they stay out of your way.

I've been in school my entire career at Boeing, thats how you move around internally.

I finished my PMAP (Pre-Management Assessment Program) but as I search for a 1st line management job, I'm discovering I'm up against candidates who have a Masters.  I'm working on that as we speak, but a shortened program that is actually a Masters Certification in Project Management, it is not to be confused with a degree.

What do you do to supply bread on the table, Sirloin?

I'm just a assembly line worker..hehe!..We have our own sensk of humour about how management types always seem to have no hair.

"just"?? The best time of my life was "just" working as a manufacturing toolmaker. That job payed less, but was a helluva lot more enjoyable than orchastrating others to do their jobs at the activity level.

The "no-hair" is a requirement so that when they get angry, you can see that their whole head is red, not just their face. It tends to get the message across better.

What the hell are you doing up so early? You must have kids...
