okay...so ive been working on designing a tail gearbox (TGB) and intermediate gearbox (IGB) for butler for about 9 months now. the tgb and igb are extremely important parts of the helicopter, they make the blades on the tail of helicopter spin. (without it, helicopters cant fly).
we have been in the preliminary design phase (PD) the entire 9 months, and the design review that the customer (sikorsky) must give the military (navair) is approaching. actually, our PDR must be complete and given to sikorsky for review in less than 2 weeks.
heres the status of the TGB
the tgb is about 30-40 lbs OVER-weight (thats alot), and doesnt meet ANY of the stress criterion (much less the severe stress criterion where it needs work when part of it is broken). im also pretty sure that even with fancy manufacturing techniques, that we cant even make this stupid piece of junk. the cherry on the top of this shit cake? the loads we use as a stress group to evaluate the design have just been INCREASED by 30%.....
30%!!!!! WTF, 2 weeks before PDR the all-knowing sikorsky engineers realize the loads theyve been giving us for 9 months(!) are incorrect. So, we have 2 weeks to fix a design that hasnt worked since day 1, only now the loads are 30% higher.
well, thisll be fun. When the year 2011 comes around, and you get a chance to fly in the new CH53-K Heavy Lift helicopter...dont...trust me.

I feel like you just leaked us classified information....
How does anything in the world ever get built....There must be one engineer out there with Howard Roark-esque abilities building everything
I don't think that this is how a good engineering firm opperates. I want to know what has Butler built successfully? Do they have a reputation for building shitty helicopters that are never able to fly or is this a rare thing?
going off of fountainhead, butler might be the peter keating of helicopter building and never able to do it themselves- constantly relying on others to fix their crap.
ironically butler has a decent reputation as a design firm... you could say we are howard roark to sikorskys peter keating.
that being said, this is still a joke of an engineering firm
its truly sad....
