The Next video is about The N.A.C.A. and the big effect they had on US air power

Looking forward to the N.A.C.A. Video. I’ve been interested in the P-30 and would like to know more about its development. I know that there was a turbocharged V-1570 but I haven’t been able to confirm that there were any altitude rated mechanical supercharged versions of that engine. Realize that was a fairly obscure aircraft but thought it might make a future video.

I found a “what if” article on NACA and the P- 38. https://www.alternatehistory.com/forum/threads/wi-naca-modified-p-38.419398/. Perhaps it may be of some interest.

Looking forward to hearing more on NACA! Also, what happened to your video about the wright brothers? I went to find it again today and cannot locate it anymore.

Thanks Greg. NACA was a very important agency that contributed greatly to the Allied war effort during World War 2. I also downloaded several airfoil research papers that are quite amazing. I’m definitely looking forward to your video.

Thanks Greg! This one should be GOOD!

Great! NACA made astonishing contributions to the American and the global aviation industry. They have been too much ignored; I suspect because as a governmental institution, they didn’t fit the American self-image or some convenient political narratives. But they were foundational, like DFS in Göttingen, TsAGI, or the RAE, and more important than any of those.

Yes!

Excellent topic! As an active aerospace engineer working on a variety of prototype aircraft currently and over the last 30 years, I learn from and reference old NACA papers (fully searchable and available on NTRS) at least a few times a week. They’re still relevant!

Nice. I was hoping for this topic for a while because I think it will help the broader audience understand why you refer to NACA so much and how important they were.

This is great! NACA was an amazing combination of government, universities and companies doing an astonishing array of cooperative research both theoretical that mostly tied directly to applied practical engineering. I used their 1930's to '50's reports and memos throughout my career. One bit of their research I used in the 2000's was a very practical way to quickly determine the limits for wing span and thickness limits to avoid flutter and divergence for wings going through the critical Mach 1 regime. It was tied first to pioneering 1930's advanced theoretical analysis, then used compilations of hundreds of various model tests of transonic wings in the 1940's that either came apart or didn't to establish a quick criteria for new design. Current computer methods are great, but extremely clumsy and time consuming. 1940's NACA gave us a shortcut starting point. They did these kind of practical applied research across the vast subjects of aircraft and engines. We were still doing aircraft testing in historic wind tunnels built by NACA in the 1930's.

Trivia: For many years I worked in one of the earliest dedicated NACA buildings, N-210 at Moffett Field.

I think you're the _only_ historical source that emphasizes them at all. They're mentioned in passing in most aircraft model histories and that is about it. Worth mentioning: They had a big impact on everyone else's air power too, the Germans certainly loved the NACA wing designs.

Getting a separate government research arm truely dedicated to aeronautics again would probably be a good move. NASA has treated aeronautics as a stepchild since the 1980's. Even the X-59 QueSST test article could have been done at least 10 years ago. We also need to be funding new wind tunnels that can provide closer to full scale supersonic Reynolds Numbers.

I did a bit of research into the NACA cowl a few months ago. Suffice to say that the NACA is a seriously under discussed topic especially considering how much they advanced aviation in the US during the inter-war period, which set the US up to be ready for WWII.

Greg, you've mentioned NACA research and influence in many videos, and it opened my eyes, not previously known how reliant US aircraft companies were on those airfoil designs. But a deeper dive into NACA would be very interesting for sure.

I'm looking forward to this. Did manufacturers such as Seversky/Republic/Consolidated ever submit their airfoil designs to NACA for testing?

Sounds like a topic I haven’t really thought about, but looking forward to it.
