Payen Pa.22

In 1935 Nicolas Roland Payen began design of a tandem-wing airplane to be powered by a ramjet being developed by H. F. Malot. The engine did not work and Payen completed the design of his Model Pa.22 Flechair (Arrow) around an 8 litre 180 HP Regnier 6B-01 inverted, six cylinder, inline, air-cooled engine for the 1939 Coupé Deutsch de la Meurthe race. The unflown Pa.22 was being tested in the Eiffel Laboratories full-size wind tunnel at Chalais-Meudon when Paris fell to the Germans.
