Jean Henri Bertin (5 September 1917 â€“ 21 December 1975) was a French scientist, engineer and inventor. He was born in Druyes-les-Belles-Fontaines and died in Neuilly-sur-Seine. He is best known as the lead engineer for the French experimental Aérotrain mass transit system. He studied at the École Polytechnique (graduating in 1938) and at the École nationale supérieure de l'aéronautique et de l'espace. From 1944 he worked for the French National Society for the Development of Aircraft Engines ( Société nationale d'études et de construction de moteurs d'aviation). In 1955 he founded the company Bertin & Cie, whose most famous activity was the development of the Aérotrain The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917–1975) – and intended to bring the French rail network to the c ....

Neuilly-sur-Seine
Neuilly-sur-Seine (; literally 'Neuilly on Seine'), also known simply as Neuilly, is a commune in the department of Hauts-de-Seine in France, just west of Paris. Immediately adjacent to the city, the area is composed of mostly select residential neighbourhoods, as well as many corporate headquarters and a handful of foreign embassies. It is the wealthiest and most expensive suburb of Paris. Together with the 16th and 7th arrondissement of Paris, the town of Neuilly-sur-Seine forms the most affluent and prestigious residential area in the whole of France. It has the 2nd highest average household income in France, at €112,504 per year (in 2020). History Originally Pont de Neuilly was a small hamlet under the jurisdiction of Villiers, a larger settlement mentioned in medieval sources as early as 832 and now absorbed by the commune of Levallois-Perret. It was not until 1222 that the little settlement of Neuilly, established on the banks of the Seine, was mentioned for the first t ...

Safran Aircraft Engines
Safran Aircraft Engines, previously Snecma (''Société nationale d'études et de construction de moteurs d'aviation'') or Snecma Moteurs, is a French aerospace engine manufacturer headquartered in Courcouronnes and a subsidiary of Safran. It designs, manufactures and maintains engines for commercial and military aircraft as well as rocket engines for launch vehicles and satellites. Some of its notable developments, alone or in partnership, include the Dassault Rafale's M88 engine, the Concorde's Olympus 593, the CFM56/ CFM-LEAP for single-aisle airliners, and the Ariane 5's Vulcain engine.

Aérotrain
The Aérotrain was an experimental Tracked Air Cushion Vehicle (TACV), or hovertrain, developed in France from 1965 to 1977 under the engineering leadership of Jean Bertin (1917–1975) – and intended to bring the French rail network to the cutting edge of land-based public transportation. Though similar to a maglev design, which levitates a train car over a complex electromagnetic track to eliminate all resistance other than aerodynamic drag, the Aérotrain – also a "train without wheels" – rode on an air cushion over a simple reinforced concrete track or ''guideway'' and could travel at the speed of a maglev train, without the further technical complexity and expense of its track. In many respects, the entire concept resembled a product of the aircraft rather than rail industry. History In 1969, a U.S. company, Rohr Industries, licensed the Aérotrain technology to build the hovertrains in the United States. That same year the Aérotrain established the world record ...
