According to a French publication from 1952, the aircraft presented by engineer Mr. Roussel was a new contribution to the development of light aviation.

“Roussel airplane and engine”

-The airplane, with the double boom formula had a “pusher” engine. In general terms it may be inspired by the English DeHavilland Vampire plane.

-The propeller is therefore not a puller but a pusher. All propellers mounted behind an engine have the advantage of receiving its heat and do not require a very complete anti-icing system.

-The engine was also conceived by Mr. Roussel, it was a “three double cylinders” with six pistons and a four-stroke cycle, with gasoline injection. It had reducing gear and a transmission to the propeller.

We have more details about the engine designed by M. Roussel for his own airplane with propeller that appears in the main text.

-Other information tells us that the engine has 6 cylinders with two opposed pistons each and is two-stroke (in the main text it says that it is four-stroke).

-It has a fuel injection system and ran smoothly without mechanical noises.

-The engine gave 70/80 HP at 2,000 rpm. The total displacement was 1,700 cc.

-Now we show another project by Roussel, it is a small fighter plane that was powered by a Gnome-Rhone 14 “Mars” (see).

-It was destroyed in 1940 possibly when the Germans entered France.

-See appendix 9 of ROUSSEL-PEUGEOT on the next page. (Sometimes Rousel-Peugeot or Peugeot-Rousel)

The engineer Roussel made the engine with 3 horizontal cylinders with two pistons each and a 2-stroke cycle.

-In each cylinder the pistons acted in opposite positions, with the ignition in the center of the cylinder. The intake was carried out on one side (at the BDC of one piston) and the exhaust was carried out through the BDC of the other piston. There was a supercharger to force feed and scavenge into the cylinder.

-The two crankshafts were at the outer ends of the cylinder, and both crankshafts were interconnected. It was geared.

-In a way it was the idea of the Junkers Jumo 200 series (205, 206, etc.) that were similar but in a vertical position.
