Propulsion / Re: FIAT A.40
« Last post by Skybolt on Today at 04:54:57 am »
In the very new "Il motore Aeronautico FIAT" by Francesco Greco, published by Gli Archivi Ritrovati (i.e. Paolo Miana) there is very faded complete drawing of the A-40. Print too small and lines too faded to hint the drawing date. If someone has the original or a better scan, could possibly post the date here, please.

Hi,

also there was a PL-152,which developed from PL-151,but no more details are known.

My dear Skyblazer,

I am sure about M-177,and for Model-167;

CP 38-385 : Martin M-167,CP 39-460 : Martin M-167A.

Amazing work as usual my dear Skyblazer,
and I can add;
CP 38-385  also Curtiss Model-83
CP 39-460  also Martin M-177
CP 39-640  also Burnelli XBA-1,Consolidated LB-22 & LB-24,Chance Vought V-302
                 and Martin M-178

Thanks. I've added these to my spreadsheet and will eventually update the PDF.
I realize I made a mistake about the Stearman in CP 39-640, which was NOT the XA-21.

Are you quite sure about the Martin 177 being submitted along with the Model 167? I haven't found a reference for this.
(I don't use the M- prefix for Martin, as the company itself didn't seem to use it)

I want to understand,why many different prefix and what was the differences between them, D,DS,SS & TS ?.

If I'm not mistaken, D- was for Design, DS- for Design Specification, TS- for Type Specification and SS- for System Specification.

Thank you my dear Skyblazer.

AETP may be splitting into two programs: F135 replacement and classified 6th-gen development.

That seems like it could be a good sign.  Perhaps PCA planning is far enough along that a divergence of the technology has been required.

As I was looking for a place to add U.S. Army Air Corps Specification R-1800-D in my files, I happened on a list which I started many years ago, working from many different sources (books, mostly) and had completely forgotten about. Unless I'm mistaken, I don't think I've ever shared it before on this forum, nor have I ever seen its equivalent anywhere on the web (if I'm wrong by all means please let me know).

I've compiled it for you in PDF form and I hope it will be of interest to some of you.

Also, I'm adding a second PDF with the list of Draft Specifications that I already shared previously in this topic, and a third one with Circular Proposals.
When new allocations emerge, I will update the PDF files accordingly.

Unfortunately I still don't have a list for Requests for Proposal such as the late Steve Pace was asking for in the initial post of this thread.
