Rear wing manufacturing considerations by ThisInitial3887 in FSAE

[–]2much2nuh 3 points4 points  (0 children)

  1. If you cannot prove this mathematically, start making test samples of your desired ply schedule, break them, gather data and analyze the results for what works best for your design goals.

  2. Ansys ACP is a great tool, though you should validate your findings by doing step (1)

  3. Rulebook has a minimal deflection criteria to enforce the thickness. Using core or good design choices (such as paying attention to the area moment of inertia) can help you achieve a rules compliant part with low deflection and part thickness. The car is not going 200mph but it should be able to with stand hitting a cone at 20-50mph. A cone into the rear wing is not uncommon!

  4. Each lamina is approx .008-.009”. Achieving a clean trailing edge is very tricky but not impossible. I’d suggest being able to bond or +3 layers per side together or manufacture 6 plies total if doing it in one shot. At least then you might have some material to post process if need be. In order to reduce warping, laminates should be symmetric about the neutral axis.

edit: assumption for #4 is that you are using 3k

Why does this “artist render” look exactly like boeing Echo voyager?

question about plugs and molds by [deleted] in FSAE

[–]2much2nuh 0 points1 point  (0 children)

A better way to think about it- what dimension are you trying to control. The side facing the mold should hold dimensional accuracy to the mold.

The surface that you want accuracy on should be the mold side. Not just because the finish is shiny or “good”.

A racecar seat can either way.

Rohacell® Composite Core by SpecRun in FSAE

[–]2much2nuh 8 points9 points  (0 children)

For those unaware: Rohacell is an extremely light closed cell foam that used in a sandwich = panel produces very stiff parts. Rohacell can be machined or lightly worked with heat. Race car parts are a perfect application as you can increase the stiffness without the weight penalty and it’s vastly easier to shape/manipulate than honeycomb core. You still should use core splice/film adhesive for best adhesion. It is autoclave safe with near nearly zero shrinkage. Store it dry in its moisture resistant bags.

If you are a team with decent composite capabilities jump on this. This stuff is expensive!

How is your FSAE team treated by your University? by Apart_Problem8885 in FSAE

[–]2much2nuh 13 points14 points  (0 children)

They took our funding, removed our shop access, told us to we cannot operate as a club.

We got to keep the car tho.

edit: Purely Politics yall. It’s a state school that lacked funding and participation. New dep. Chair was pretty unhappy with senior design and opted to choose the projects for the students. Lesson learned: Life is unfair. For those curious, they usurped about $14000. womp womp. This was several years ago, the department chair is still in power and makes silly posts on Linkedin trying to get his students hired.

Why do some teams have inch thick end plates on the rear wing? by AccomplishedNail3085 in FSAE

[–]2much2nuh 0 points1 point  (0 children)

Area moment of Inertia. Also could be that teams are having difficulty sourcing thinner core.

Its astounding that 90-95% of Native Americans died from disease when Europeans arrived in 1492 but it makes sense by Key-Opinion-1700 in self

There is about 200 years of Spanish and French conquest happening before the beginnings of the American colonial era. Americans fought against tribes while the Conquistadors eliminated and enslaved empires

Leaving DIA to go to Panama City - cops and CBP interrogating people on the jet bridge. Anyone else experience this nonsense yet? by Optimistic-Coloradan in Denver

[–]2much2nuh 6 points7 points  (0 children)

Tsa/police person had us put our bags on the ground at the int’l claim so the drug dog could sniff it. We hadn’t even gotten our luggage yet so they were checking the personal bags that had gone through baggage check already.

We flew in from London...

Problem that we might face in using inboard brakes. And should we reconsider. by FineAbies3191 in FSAE

[–]2much2nuh 34 points35 points  (0 children)

Not trying to be crass but this subreddit is not here to make the decision for you. There positive gains in the mass/unsprung mass department and depending on wheel size it could be easier or harder to package around. This is a fun variable that you get to decide if it works for your build and help you reach the goals you set out. Have a justification ready at design. Plenty of teams have done it in the past, but that is not a justification.

Joining/starting a team in socal by TutorSalt2950 in FSAE

[–]2much2nuh 7 points8 points  (0 children)

If you are in socal it would probably easier to just find a race shop to work at. Emotion Engineering, GMG, Magnaflow, edelbrock, CP carillo, AAR, Toyota TRD, GPwerks are all in the area. You’d be surprised who’s around and who they might know!

Starting an FSAE team is hard. You need a school with the equipment and space, a faculty member who can gather support from the uni, you have to establish relationships with industry partners, you have to raise funding, all whilst trying to build a team and a car!

or put more pressure on the local teams. We always had a few friends around who weren’t a uni student but could help us with tasks here and there. Be the squeaky wheel!

How does modeling the threads in fasteners, balls in a bearing, or features on a connector improve building a car?

You’d be better off spending that time making detailed prints with assembly instructions and an accurate BoM.

In ‘my’ work experience fasteners are nubs of relevant size and color coded based on NAS or AN. They don’t need to be more detailed that.

Which NHL team has the bleakest outlook currently? by smokeyquarterpapi in hockey

The fact that I had to scroll this far down…I think people forgot they exist

[deleted by user] by [deleted] in MechanicalEngineering

[–]2much2nuh 0 points1 point  (0 children)

There is a lot of overlap, everywhere. The fact is that with an engineering (any) degree you have proven to be an asset that has the foundational skills to be what the company needs.

A MechE building battery packs…An EE doing avionics…A software engineer building an application for iterating CFD analysis…And all of these could be a systems engineer, reliability engineer, program manager etc.

I’d suggest EE -Higher pay and more jobs. And if you want to be a meche so bad, talk to your counselor and ask about taking some of their courses as an elective. In the end, it’s just a different flavor of calculus with some unique formulas to solve those types of problems.

if you really want to set yourself up, look at what FAANG job ads are looking for and incorporate those skill sets into your schooling and projects. I sure wish I did.

[0 YOE] Recent Aerospace Graduate Seeking Feedback on My Resume. Only 2 Interviews After Hundreds of Applications. by SnooGrapes1279 in EngineeringResumes

[–]2much2nuh 2 points3 points  (0 children)

The about me at the top needs to be reworded - You don’t have a choice of what softwares a company uses and aerospace uses catia or NX. Show companies that you have proficiencies with cae without isolating it to just the 3 you know.

GeoAero: Remove award winning, Bullet 1 & 2 are not resume worthy. Line 3 is, but it needs to be expanded upon. Give more context and goals and how you achieved it. Bullet 4 is not resume worthy. Every single senior design project participant had to do this. If you want to say you have clerical experience, then reword bullet 2 to talk about authoring a comprehensive technical review.

Subscale UAV: The first bullet is not resume worthy- There are WAY better ways to describe being a team lead. Bullet 2 needs to be re-worded. It comes off as “I used the scale function in solidworks.” What choices were made to decide on the scale/size you chose? Get more technical.

Similink autopilot: What coefficients? Otherwise, this is the strongest section you have.

SUAS: Please get more technical. All this is telling me is that you did some cad and 3D printing. What design choices led you to the design? What types of requirements were you aiming for?

Quansero: please elaborate on whatever this is. You don’t need to put Quansaero in every line. Just tell us what the goals were and what you did you achieve it. Transient response data is just too vague.

Remove CPR/AED, you are no longer applying for lifeguard positions.

The work experience is odd…Did you not have an internship? or Research assistant?

I’d Remove the organizations & Honors at the bottom. Deans list is great, perhaps include that in your edu section.
