Does anyone know where I can obtain this document? ESSCO doesn't have it on their website. Amazon, Ebay and Google searches have turned up no clues.

I can't find any record of ANC-4 or what it contained.

Have you looked at ANC-18 "Design of Wood Aircraft Structures"? The title of chapter 3 is "Methods of Structural Analysis", Chapter 4 is "Detail Structural Design"

I have a pdf copy, if your email provider allows files that big I can try to send it to you.

Mike, I would be interested in a copy if you don't mind. Wooden aircraft are not my thing at the moment, but I never turn down the chance to learn something that might be useful in the future.

Mike,

Thanks for the reply. I do have ANC-18. The first paragraph of chapter three makes reference to ANC-4. That's how I learned about it.

I'm interested in learning about all the ANC documents. But I've not found a good source for them or anyone knowledgeable about them.

I forgot to mention in my original post that I also tried the NASA report server. But that also turned up nothing.

It's as if this great resource for a/c design has vanished, or perhaps is vanishing, into history.

I'm still hopeful my post will turn up someone with more informaiton.

Regards,

Are you referring to the Army Navy civil aircraft bulletin reports? If so, you might try the National Archives, Library of Congress or perhaps the DTIC online library.

If you know anyone that works at a university with access to a research library they might be able to find it (most of them are linked in an online system). I know someone I can ask but she is on sabbatical so it might take a little bit.

My guess would be that ANC-4 was superseded by a later publication.

Edit - I sent an email to someone real good at historical document research, if she can't find it nobody can

So far ANC-4 is proving to be elusive. We did find the following in the bibliography of an AGARD report too big to post here

ANC - 1 (1) SPANWISE AIR LOAD DISTRIBUTION - NAVY
ANC - 1 (2) CHORDWISE AIR LOAD DISTRIBUTION - NAVY
ANC - 1 (3) DETERMINATION OF POINTS OF APPLICATION OF RESULTANT AIR LOADS - NAVY

ANC - 3 WATER LOADS = NAVY AND BUREAU OF AIR COMMERCE

Oh, and the University of Michigan has an October 1940 copy of ANC-5

(Working on getting a pdf of that)

I have found copies of ANC-12 (apparently I had a copy and didn't realize it) and ANC-5 (http://www.westcoastpiet.com/images/Construction/Strength of Metal Aircraft Elements.pdf) .

I also found part of ANC-19 (http://www.westcoastpiet.com/images/Construction/ANC-19 pg 118 to 126.pdf)

I found this on another forum:

Copies of the following publications are available upon request from the Small Airplane Directorate, Standards Office, Federal Aviation Administration, DOT Building, 901 Locust Street, Room 301, Kansas City, Missouri 64106:
ANC-1(1), Spanwise Air-Load Distribution, Army-Navy-Commerce Committee on Aircraft Requirements, 1938. ANC-1(2), Chordwise Air-Load Distribution, Army-Navy-Civil Committee on Aircraft Design Criteria, Amendment –1 dated 3 January 1944.

These might also be useful (stuff I found while searching):

Steve - I got an email with the same info in what you quoted, my "research assistant" (with a doctorate & 3 masters) seems to think they might have copies of all the ANC publications

Also, she thinks there is a collection in a library at Wichita State University that has most of them (as well as a lot of other nifty stuff)


(She quit looking when "The Closer" came on)

That's one hell of a research assistant. You mean your wife right? LOL

Those qualifications sound like myself (when I'm done) and my girlfriend (when she's done):
Me: Bachelors in motorsports engineering (minor in German language); masters in flight test engineering, masters in biomedical or aerospace engineering; doctorate in epidemiology
Her: Bachelors in psychology; masters in forensic psych; a second masters in something I forget (don't tell her!) and a doctorate in clinical psychology

I've managed to stay unmarried. :) And I "only" have a BSME from Rose Hulman.

The research assistant is my sister, I wont go into a lot of detail online as she has a stalker, but she is a university department chair. I give her grief about going to school all those years to be a piece of furniture. :D

That's nothing to sneeze at. BTW, I grew up in and around Terre Haute.

Steve,

Thanks for the suggestion. It appears the national archives has it. I've sent an email inquiring what it takes to get my hands on a copy.

Patrick,
If you get a copy, might I ask for you to send me one as well?

Let us know also if it is available, if it is print or pdf.

Why not just get a copy of Bruhn instead?

It is the aerospace industry standard for the past 60 years!
