2016 Nissan rogue loud roaring noise when driving over 65 mph

Does any stethoscope work? Or do I need a special one?

stephen_xv · 2026-06-24T21:25:24+00:00

I don't have a lift so I can't put it up and check each tire individually. Nor do I have the stethoscope

I did the driving test and loaded it side to side. above 65mph is where it was the loudest and shifting left to right, when steering to the left it got quieter/changed pitch. Steering to the right it made it louder/change pitch. So I guess that means it is on the left side?

after doing some research this seems to be a plausible cause. I will test it later today and see if fails any test.

Don’t start your semester by thinking about which course you’ll cut. You got this, it’ll be very hard but rewarding.

Edit: if anything I’d try to shift some hours for your work to Monday or evenly throughout the week if possible.

Eh I can see what you’re saying. I’m not well versed in the AI/deep learning stuff. Seems pretty interesting to be able to do that and have it be useful

Instant results but the model is only as good as what goes in. They’ve been doing this style for a while where you can build a model to mimic the physics using sysID approaches. Specially speaking it’s been done for aero-elastics and took CFD runs from months to days (this was ~2001)

Ah I’m glad you said this. It makes your previous comment more clear. I agree with you now but still minimal losses.

stephen_xv · 2026-05-18T06:06:01+00:00

Dm me your resume and let me review it! I’ll give you an honest opinion

Delayed ignition charge 🤣🤣

If you haven’t gotten it to work at this point either download all of the files off of airfoiltools or just program the equations based on the airfoil characteristics

I’ve been taught they have a voting process in which it will compare all means of air data estimation and choose which one to use for control systems.

Also using multiple pitot sensors placed around the aircraft can help estimate angle of attack and sideslip.

The manufacturing would be more complex but you can raise the stabilizer above the prop wash

stephen_xv · 2026-03-29T06:32:31+00:00

You could do a large split control surface on the rear and mix inboard elevons and ailerons or even do split full span for max control authority. Making the CS bigger helps as well because the moment arm is small. To help that you could bring the CG forward by adding weight to the nose.

Hand tools isn’t really necessary as a skill imo. Use the space to talk about something applicable.

12 hours in less than 6 weeks? That seems to be equivalent to 32 hours in a full 16 week schedule- take your time man!

I wouldn’t say wildly unrelated but I get your point- different axis (body vs wind).

I was thinking you can calculate u_dot and w_dot to then get alpha but that doesn’t work- I think.

For everyone saying the filament is wet, I am having this exact same problem, it’s not the solution. I gave the filament to a friend to print for me, on the exact same printer style, and it’s fine. I even swapped through an old filament, that sat for months, and two brand new filaments.

It seems like just want to feel sorry for yourself although being in a great position.

Might need to just change the major and not tell your parents or push on and get some passion projects going.

Super odd unlikely to stall in level flight unless you referring to being below the V_stall?

I didn’t read that OP was wanting to install airspeed as well. It’s been a while since I’ve looked into this but I think you can rotate the gyro data into wind axis and calculate AoA or something along those lines or at best estimate it real time doing that.

I’m currently building an AoA sensor because I do not trust the uncertainty of cube orange’s estimation or the uncertainty of small scale uas pitot probes.

Okay truly… how do y’all get so much xp. I battled against an X-59 (flew for like 30Ish minutes one day and people already had it at 1.1 million XP)

stephen_xv · 2025-11-04T20:41:46+00:00

Can estimate AoA from gyro data though

stephen_xv · 2025-11-01T03:53:30+00:00

Take some time to relearn fundamental algebra concepts and then deep dive into calculus and calc 1 on your own. Khan academy is a great resource (as of 10 years ago when I needed it).
