NACA projects

[Stargazer]

As there is a topic on NASA projects in the post-1945, I elect to create this sister topic on pre-1945 projects. Of course NACA didn't become NASA in 1945, but this is to roughly separate the projects of the jet age from those of the early days. Instead of creating a new topic each time a new project is found (which I find very frustrating and complicated because a lot of valuable data is scattered all over the place) I prefer to regroup all the projects that are obscure and not sufficiently documented at present time. Separate topics will follow if more can be added about one of these.

I would like to start by what I consider a true gem: a pusher powered glider design, dated 1940-3-22:

Congrats for the finding, a true gem. But I think that's not a powered glided, It seems a study related to the Douglas DS-312A fighter design.

What you're saying makes sense, the two designs are pretty similar!

Hi,


from Les Ailes journal,here is a three different flying boat projected by NACA;

Very interesting. These were obviously in the public domain by 1935 but I cannot find any NACA report on the subject. Does anyone know where the original information could have been published?

Hi Skyblazer,


here is the same drawing from NASA;

Hesham, the aircraft shown in that illustration has nothing to do with NACA.
The article is about how inventors can protect their ideas through patents or by submitting ideas to government agencies, including NACA.

Of course you're refering here to hesham's 2014 post.

The aircraft in the 2016 post (a photo indeed, not an illustration) was NACA's own Fairchild 22, as evidenced by the STOL wing slots and the NACA shield on the tail.

 

[Schneiderman]

No, my mistake.

Some neat looking radial fighter variations that started off as a seversky

This type of cowling pops up in some other reports, as does the canopy and wing.

Hi,

here is a Project called J-3 and a tailless glider,I don't know if they were for NACA only,
or associated with anther company ?.

Thank you Dear Schneiderman.

From the book, Flying for 1938,

what was it ?.

many people proposed and even test-flew airplanes with long tail drive shafts, but they suffered form torsional vibration. Long drive shafts only became practical when smooth-turning jet engines were introduced during the 1950s.

Here is NACA Model-22A;

Tank Tests of a Family of Flying-boat Hulls

This report presents towing tests made in the N.A.C.A. tank of a parent form and five variations of a flying-boat hull. The beams of two of the dervied forms were made the same as that of the parent and the lengths changed by increasing and decreasing the spacing of stations. The lengths of two...

Be aware that the numbering on the models does not equate to model numbers as used by manufacturers.
It's not a project number and most of the N.A.C.A work cannot actually be considered as projects in the
sense usually applied here, they were research studies and only projects in a very generic sense rather than
specific design projects.

Of course I know that very well my dear Jcf,

and we have this topic;

Hi,

for the fighter's Model,I think we discussed it before,but where ?.

Wartime Report

Reproductions of reports, some declassified, of research done at Langley Memorial Aeronautical Laboratory during World War II. The order of reports does not represent when they were chronologically issued. Reference to the original version of each report is included.
