Zipfel No. 1

Armand Zipfel was a neighbour and youth friend of the Voisin brothers. After witnessing the flights of Henry Farman he decided in early 1908 to build a motorized airplane. He started the “Ateliers d’Aviation de Sud Est” and was allowed to use the drawings of the Voisin plane. He made his first flights at Villeurbaine, east of Lyon, in November 1908, becoming the sixth Frenchman to fly. He then toured Europe displaying the machine during 1909, visiting Berlin, Constantinople and Lisbon, also making an unsuccessful appearance at the Vichy Aviation meeting. After another visit to Germany in early 1910 he appears to have stopped flying in public.

Zimmerman Flying Pancake

Wind tunnel testing (NACA)

The 1935 single place low-aspect-ratio “flying pancake” developed in off-times by C H Zimmerman, John McKellar, and Richard Noyes, then with NACA, for design competition with Ercoupe and Stearman- Hammond. US patent #2,108,093 was issued to Zimmerman in 1938. Although rejected by NACA at too radical, despite its potential as a stall-proof airplane, elements of the design surfaced later in Vought V-173 and Vought-Sikorsky XF5U-1.

Unable to synchronize the motors, rather than risk an accident the project was abandoned and it never flew.
