(sometimes Givaudan-Vermorel)

The Givaudan engine, which was tried out in April-May 1909, seemed a special engine that was studied and built by Vermorel in order to propel the inventor's original multi-cellular flying machine with concentric drums. Eventually this machine did not fly.

-It was an 8-cylinder V-engine that gave 40 CV, The piston diameter was 90 mm and the stroke was 120 mm. It weighed 80 Kgs., including flywheel, carburetors and magneto. The oil too, of course.

-The magneto was mounted at front of the engine and the control gears were visible under it.

-When M. Givaudan was building this aviation engine, he already had great experience in V-engines since he was one of the first to build them, in 1899, for industrial purposes.

-In the collaboration with Vermorel, who also made the triple plane, the Vermorel engine was alternated with the Givaudan one.

From Appendix 12: The V8 engine was designed by Claudius Givaudan and manufactured by the Vermorel automobile construction company.

“V8 Givaudan-Vermorel”

-It is not a car engine adapted by Givaudan since the most similar is a water-cooled V8, and this one is an air-cooled engine specifically for aircraft.
