Hello everyone,

Has anyone ever come across reliable maneuvering data on the D3A1, namely the roll rate?

Thanks!
 
I'll see if I can dig up my Japanese books on the subject. I obtained a few years back a whole series that I found referenced on combinedfleet.com . Also, do you have Peter Smith's book on the Val?
 
The Peter Smith book on the Val (Crowood books) is one of the best books ever written on a single plane. It gives the original requirement for the "11th Research Carrier Dive Bomber" to be ....dogfight maneuverability after bomb release to be comparable with those of fighter aircraft................

I didn't see any actual angular data on maneuvering from a quick skim through. Although the book even has tables on test oil temperature etc.....!

There is a US account of "Val" pairs doing a "thach weave" type team tactic vs a Wildcat during Guadalcanal.
 
Thanks for the input! I know the "Val 11" was covered in TAIC Report 15 but I've not been able to source that report yet. I doubt it has maneuverability data but you never know!

And no, I do not have the Smith book. Might be something I need to look into!
 
I have the d3a1 Designer Notes

This is the D3A1 prototype achievement AM17 is the Aichi Municipal Number
Amazing! I also echo shinpachi-san's request to see more pages. There is a D3A undergoing restoration at Pearl Harbor, I am trying to find as much original info and blueprints as I can.

EDIT: It seems the book was created by Aichi Kokuki KK designer Ozaki-san, whose name comes up in Peter C. Smith's book on the Val:

Frankly, I am not interested in D3A so much but here 瀬戸地下軍需工場 is a group of Aichi Aircraft research enthusiasts in Japan.
You can contact with them by mail.

The underlined seems to be the same reports CN AK12 posted.
