These are conceptual design layout drawings, sketches, and model photos of examples of the earliest stages of aircraft design. Most of these were never built - we typically design hundreds of aircraft concepts at the "conceptual" level for every one that ever actually flies. Thanks to Lockheed, Rockwell, AIAA, and others for making these available. More will be added regularly. There are a lot of new drawings, and the drawings previously on this website have been processed and cleaned up. Some are still rather poor, but these are the best available at this time.

Additional contributions are greatly desired, especially 3-view drawings of unusual designs. Please email scans to Conceptual Research Corporation or mail them to CRC at PO Box 5429, Playa del Rey, CA 90296.
