Warbirds / Microfilm passing Atlantic WWII
« Last post by KESTL on May 18, 2020, 03:14:56 PM »
Hello everyone.

For some time I have been deep in research surrounding the circumstances of a flight, or rather a series of flights, that happened  in 1942. I’m writing this post as I have not been able to come up with a reliable answer to (1) which aircraft were used and (2) on which dates the flights occurred.

My interest in aviation in general started not so long ago, when I saw a video displaying the wonders of the new Microsoft Flight Simulator “game”. It looks absolutely magnificent and their continuing efforts on describing all the mechanics that go into it, keep delivering for a promising true to life experience. I CAN’T WAIT.

I am a classical musician by profession, and I have always been fascinated with the story of how Shostakovich’s 7th symphony made the trip from war torn Russia to United States, for a premiere to be played in New York 4 months after the world premiere. In the last few weeks I have tried to find more information on the specifics of these flights through the book: “Symphony for the city of the dead”, by M.T. Anderson, and the paper: “Flight of the seventh”, also by M.T. Anderson. I have come up with the following (if anyone decides to find leads by themselves or know more please correct me at any step of the way):
Kuybyshev, Russia (present day Samara, Russia)- Tehran, Iran (by plane)
Tehran, Iran - Cairo, Egypt (hired courier by car)
Cairo, Egypt (Payne Airfield) - either Casablanca then Accra or direct to Accra (by plane)
Accra - Recife, Brazil (Ibura airfield) (by plane)
Recife, Brazil - Florida (most likely Miami) (by plane, U.S. Navy)
Florida - Washington DC (by plane)

Anderson explains that the score and parts for the symphony, which were kept on a microfilm, were supposed to leave Kuybyshev on April 9th 1942 in the pocket of a Pan Am Pilot flying himself to Washington DC. However, the pilot in question had not received nor heard of any microfilm, when he, as the microfilm had not turned up in Washington DC, was asked about it.
Eventually it turned up in Washington DC on May 30th 1942 and later went with a Russian agent to New York.

I want to do these flights in a flight simulator, and I would like them to be as historically accurate as possible (I’m still worried about navigating over the Atlantic, though 😖).
The date span is larger than I would expect it to take (April 9th-May 30th). I’m thinking that, as it did not go with the Pan Am pilot on April 9th, it might have stayed in Kuybyshev some time before leaving for Tehran.
Regarding aircraft I would imagine it could be a C-87 taking it over the South Atlantic Air Ferry route with the ACFC (https://en.wikipedia.org/wiki/Air_Transport_Command, see ACFC foreign wing). Over land it seams the C-47/Li-2 is the best bet.

So, I guess my question is:
Are there any publicly available records showing specific cargo flights during this time period?
I would also appreciate some comments on my guess work and would also appreciate some additional guess work from more competent people than myself.

The article “Flight of the seventh” can be read for free at www.academia.edu

Thanks a bunch

Dear Fellows

I have another trivial question
For the prototype Model 299 it was 9 crews, for the B-17F and G it  was 10 cews
For the Y1B17 I read 6 crews
My question is"
what is the number of crew and function for the Model  299, Y1B17, Y1B19A, B-17-B, B-17C,

Thanks in advance

Dear Niels Hillebrand,

Thanks a lot for the information you sent to me.

Let me read it, maybe I will come back to you.

Greetings from China, have a nice day

Best regards

As told in my presentation, I’m living in China and as messenger, Facebook, Twitter, even Wikipedia, other online encyclopedies are blocked by the Chinese cyber authorities my information resources are really limited…

see attachments for Wikipedia, I included some extras, so it may make some sense.

and maybe theses excellent (pre-Wikipedia era) sites will work for you:
http://www.enginehistory.org/
http://www.aviation-history.com/
just search them for the Wright R-1820.

I have questions , maybe you know the replies or maybe you can orient me to someone or somewhere.

As well I read:
The Boeing model 299 was powered by a R-1690 Hornet
The Y1B-17 by a R 1820-39 Cyclone.
The Y1B-17A by a R 1820-51 with turbocharger GE type B-2
The B-17E by a R-1820-65 cyclone.
The B-17F by a R 1820-97 cyclone with turbocharger GE typeB-2
The B-17G by a R 1820-97 cyclone with turbocharger GE type B-22

Would it be possible to know:

What are the difference between the R 1820-39, 1820-51, 1820-65, 1820-97?
They are the model numbers given by the US army, odd numbered (navy used even numbers), higher is later series model and configuration.
Sorry I don't know how they exactly align with the Wright versions/series E/F/F-50/G. I believe the 1820-97 is the G-2 model?

What the difference between the R-1690 hornet and 1820 cyclone?
P&W -vs- Wright
1690/1820 is the displacement (rounded cubic inches), the higher the more potential for power output.
P&W had more success with the R-1830 Twin Wasp (2x7=14 cylinder) than the 9 cylinder Hornet.

Difference between the turbocharger GE type B-2 and type B-22?

I can't believe I found  this: https://aviationshoppe.com/manuals/wwii_aircraft_superchargers/wwii_aircraft_turbosupercharger.html
it's from the actual manual:

"Same as Type B-2, with the following exceptions:
1. Bearing lubrication redesigned and turbine bucket wheel made of improved material which permits 24,000 rpm rated speed.
2. Has 1/2-inch flexible-rubber oil lines"

rotor speed went from 21300 rpm to 24000 rpm, weight flow increase from 110 to 120 Lb/Min at altitude 25,000 ft.

See https://aviationshoppe.com/manuals/wwii_aircraft_superchargers/wwii_aircraft_turbosupercharger.html?pageNumber=12

The difference between the 1690 hornet supercharged, the 1820 supercharged and the 1820 turbocharger?
1) different engine
2) I'm not sure about the specifics, but if I go with the definitions, a supercharger is still driven by the engine, so takes some power away. a turbo(super)charger has a turbine driven by exhaust gases. Not sure that actually applies in these cases though.

What is a R-1820 G2
Yeah, so that's the Wright model G with a certain blower ratio for the supercharger, designated G-2. So configured with the GE turbocharger, it is the same as R-1820-97 military designation?
I'm not sure, not an expert!!

anyway check out the sources.

Really sorry for all these questions,  I really don't find any replies regarding my limited information resources.

News & Announcements / Air Show Cancellations
« Last post by Webmaster on March 22, 2020, 01:27:10 AM »
The challenging and unprecedented situation presented by this global crisis has forced many organizations to cancel or postpone air shows and other public aviation events, which were scheduled to take place this spring.

The air show calendar presented on this website is updated accordingly,as announcements are being made.

As the impact and the implications are becoming more profound, also major air shows that were planned to take place over the summer have been affected. Unfortunately, more cancellations are to be expected as the situation gets worse.

Although the air show calendar will continue to be updated, event information is not always available or up-to-date.

Even once the situation improves locally and there is no indication that a listed event is cancelled, please seek confirmation that the show goes on, take into account travel restrictions and other complicating factors before making any plans.

Military Aircraft / FMA IA-58 Pucará argentinian aircraft
« Last post by capsula espacial on January 30, 2020, 02:28:39 AM »

Publication that deals with the history of one of the airplanes that the Argentine Air Force still has, the FMA IA-58 Pucará, an excellent performance twin-turboprop, used by some countries of the Southern Cone, being present in several international samples and being one of the aerial components used in the Falklands War having an outstanding performance (despite being an aircraft not suitable for a type of high-density combat such as the South Atlantic War) but which has undoubtedly been one of the best exponents created in the Military Aircraft Factory of Argentina.
