For those in the Part 23 world, curious to hear your interpretation and application of 23.603(b). No ulterior motives, purely curious to hear how others in the industry interpret this rule and show compliance to it.
In my mind it is a bit of a catch-all, showing the design is well thought...
rb,
Oh duh, on the WDC acronym. This assembly is a location not terribly accessible, so we want a more long-term solution than WDC.
I hear what you are saying about the nuance of the specific installation, but I'm not trying to debate with them (or Eng-Tips) about this specific...
rb,
They (Group 1) don't have any evidence to support their claim. I think just wishful thinking on their part, really.
I know 5052-O is not high strength. I purposefully left out details of what it is or what it does because I don't want to derail the topic with those details. It isn't...
Having a debate with another group internally. Here's the scenario: 6061-T6 plate welded to a 5052-O tube. The plate gets NAS680A3 nutplates riveted on with (alodined) AD rivets. Group 1 is pushing to weld the plate to the tube, then rivet the nutplates to the plate, then alodine the whole...
Wil, super! Thank you very much!
Now to request input from folks familiar with SCEET hose in the (aircraft) industry:
Have you seen similar delamination between the inner and outer layer?
Have you set up an inspection criteria to determine if the bond between the inner and outer layer is...
Is there a mil-spec or similar industry spec (AN, MS, NAS, AMS, ASTM, SAE, etc) that SCEET hose is made to that provides dimensional, material, and performance criteria? Like an AN960 washer spec sheet, but for SCEET hose.
The manufacturer of the SCEET hose that my company has been using for...
Interesting thread. I knew about graphite from pencils causing problems on aluminum skins. I used to work at Mooney and this was a well-known no-no there. But I hadn't heard about the issues of chlorides or acids in Sharpie ink, and hadn't thought about the carbon dye in black Sharpie ink. I...
IFRs, I worked at an composite experimental GA company for a couple of years. The airplane was mostly carbon fiber but had some fiberglass. We tried using the water jet machine to cut fiberglass but quickly eliminated it as a possibility because it created delaminations emanating radially from...
I am not quite 12 years out of school and am at my third general aviation engineering job. My thoughts, in no particular order:
-Don't fret over which CAD software you learn. Once you learn one they all essentially do the same thing and transitioning from one to another isn't as bad as you'd...
RB, valid points. I had thought about the scatter factor covering small differences. Just didn't know how small (or not small) the differences would be, though I initially guessed pretty small. I am new at this so glad to hear advice from experienced guys.
My intent is to compare a Miner's...
I am looking for S/N curves of 7075-T6511 extrusion. The closest I have found is the first S/N curve in the 7075 section of MIL-HDBK-5J (Figure 3.7.6.1.8(a)or MMPDS-01 (Figure 3.7.6.1.8(a) MMPDS-08 (Figure 3.7.9.1.8(a) and MMPDS-13 (Figure 3.7.10.1.8(a)...these are the documents I have access...
I may be stating the obvious, but bending parallel to the grain direction of the material (Option #1 image in your first post) can cause cracking on the outside of the bend if the bend radius is too small. Avoiding this cracking largely (maybe wholly) drives minimum bend radius, at least when...
Of interesting note is the 60s-era idea was for a seaplane version (not float plane). Old Lockheed sketches in link in post #2.
Maybe we just buy a few Beriev BE-200s instead.
I don't disagree. Maybe the folks who first dreamed up the idea in the 60s (and again in the 90s) came to the same conclusion and that's why it never happened. Now those people are gone and the new folks will have to come to the same conclusion. Learning [from history] is hard (sarcasm).
