I did it on excel and by hand. Just to clarify... From swift's formula: @ Fastener 1 For doubler displacement use P=R1= load fastener 1 For skin displacement use P= load in strip - R1 For rivet displacement use F= R1 than plug all other values in formula and use strain compatibility to isolate...

rb1957 the fasteners are not the problem... The outer rows are critical for the fasteners clearly and the load reduces as you get to the center of the doubler. it seems from the report that the sum of the fastner loads from the first three rows gets transfered to the doubler and this load is...

Right bf109g 3 rows on each side

So just an update and a question... I finally decided to purchase the DTA from a DER however obviously not everything and every calculations are explained in it. I have read and understood most of the report, however I am stuck on the fastener loads calculation using Swift's displacement...

Crackman, Maybe you mean the DTD handbook available from afgrow?? Link is: http://www.afgrow.net/applications/DTDHandbook/pdfs.aspx

FastMouse, This is a great small general example. Actually if the report itself was available or even the references it would be gr8. Thanks for the link. The FTA DTA handbook precise reference would be appreciated.

the doubler is installed to compensate for the hole in the skin and is riveted to the skin. The inspection will surely be on the first row... it takes the report to justify that! i am looking into courses available and found a course that seems to have what I am looking for at Cranfield U in...

i actually think my case is simpler. The antenna is GPS size; quite small and flat. I would install an internal doubler. Thanks RB I will find some more info on each of those subjects above.

Thanks for the references. Actually that is the route I was taking. I did source out the DTA to a DER and am waiting for the report. I am also looking into the U of W course but it is quite far and time consuming... 737eng it looks like you took the class? I got some of the slides from Patrick...

Hello All, Can someone provide me with a manual, tutorial, or actual example of a well detailed (with references to formulas, assumptions) DTA and stress report for installing a small antenna on fuselage crown of a transport category a/c. i have this project coming up and need to familiarise...

Taglis, the thread preceding us "whatever happened to RAPIDC" contains a link to RAPIDC. Here is the link to the thread: http://www.eng-tips.com/viewthread.cfm?qid=220355&page=1

taglia, i was able to dowload from the link provided but u only put the application file rapid.exe. i need the installer. Thanks

Debodine, This is exactly what I was looking for an explanation.

Hello All, I am trying to install on an A310 a communications antenna using L-Band frequency. I've been told that a suppression line system should be installed in order to avoid this antenna from interfering with important systems such as DME, VHF, TCAS etc. Unfortunately, I wasn't given more...

thanks taglia. Maybe i can set up an ftp for you where you can upload it. How big is it? Anyone know howcome RAPID is not offered and supported by the FAA anymore?
