Now available are scans of two large and detailed diagrams of the Northrop YF-23 stealth fighter. Included:
1) Drawing 400L005002, sheet 1 of 2: provides top, bottom, left and right inboard views, with scrap inboard views through the engine and upper avionics bay. An impressive 27,000 by 7032 pixels, black & white. Original scan was missing much of the title block, but the rest of the image is intact.
2) Drawing 400L005002, sheet 2 of 2: provides 21 cross-sections of the YF-23. Smaller than sheet one, it’s still a large 17,696 by 6,944 pixels, black and white.
Also included are grayscale half- and quarter-size versions for easier viewing and printing. Together these would make a very useful resource for model builders… either to perfect a kit, or to scratchbuilt a large-scale display or even RC flying model.
Air Drawing 47 can be downloaded for $3.
