In the Documentation Centre of the Musée de l'Air et de l'Espace Le Bourget, north of Paris, there is documentation on an engine from this aircraft manufacturer.
From Appendix 10: This is the famous pioneer of French aviation. The first to cross the English Channel, etc. At the MAE Museum in Paris, he is awarded a dossier with an aero engine.
"Bleriot two-cylinder twin engine"
"More information about this engine"
-If they awarded him the ability to build this engine, it is very likely that he also built the aircraft engine (or engines).
-I have yet to visit the MAE documentation archive in the near future to try to locate more information.
-The hobby of this man led him to do an experiment with a machine that was an ornithopter model made by Louis himself, and patented in 1901.
-The engine gave only 1,5 CV and ran on carbonic acid. In 1902 he made another major one.
