1770 FARDIER DE CUGNOT

LE PREMIER VÉHICULE AUTOMOTEUR AU MONDE

Années de production : 1770
Pays : France
Nombre produit : 1

Le Fardier (chariot à roues) à vapeur de Nicholas-Joseph Cugnot a été le premier véhicule automoteur au monde, faisant de lui le premier ingénieur automobile au monde.

Il devait concevoir et construire la première machine à vapeur dans laquelle la vapeur, à une pression supérieure à la pression atmosphérique, entraînait un piston dans un cylindre. Il a également inventé une vanne rotative activée par le piston pour laisser entrer et sortir la vapeur des deux cylindres de la machine. Le véhicule a été démontré en France en 1770, tirant un canon d'artillerie de cinq tonnes.

L'original 1770 Fardier de Cugnot fait partie de la collection du Conservatoire des Arts et Métiers, Paris, France depuis 1801. Notre Fardier est entièrement fonctionnel, fidèlereproduction qui a été créée à partir de zéro par le Tampa Bay Auto Museum et achevée en 2010.
Les ingénieurs de Polypack et du Tampa Bay Automobile Museum ont redonné vie au Fardier de Cugnot. C'est la première fois que le Fardier de Nicolas Cugnot court depuis plus de 200 ans !

Building the Replica: Tampa Bay Automobile Museum's Tribute

The project began with extensive research into the original Fardier de Cugnot. The museum's team delved into historical documents, drawings, and descriptions of the vehicle. They consulted works such as "Les Éléments de l'Art Militaire Ancien et Moderne" by Cugnot himself, as well as analyses by subsequent historians and engineers. The goal was to understand not just the physical dimensions and components of the Fardier, but also the underlying principles of its design and operation.

Research and Expert Consultation

The museum studied existing replicas, particularly the one built by the Deutsche Bahn Museum in 1935. This model provided valuable insights into the construction methods and materials that could be used. However, the museum aimed to go beyond a simple visual reproduction to create a fully functional replica that could replicate the original vehicle's performance.

To ensure historical accuracy and technical feasibility, the museum consulted with experts in steam engineering, historical vehicle restoration, and 18th-century engineering practices. This collaboration helped in making informed decisions about materials, construction techniques, and modifications necessary to achieve a working model.

The construction process involved recreating the steam engine's cylinders and pistons following General de Gribeauval's original specifications. The boiler design was modernized to address inefficiencies and safety concerns, using steel tubes to maximize heat exchange and enhance safety while incorporating historical elements. The distributor and valve mechanism were meticulously reconstructed, and the steel chassis, wooden frame, and wheels were built to match the original specifications.

Construction Process

Following General de Gribeauval's original specifications, the team produced detailed plans in both imperial and metric measurements. They identified the need to use the "Chatelet toise" for certain dimensions, ensuring historical accuracy. The cylinders were cast using sand molding techniques in Tampa, Florida, and then machined to precise tolerances in the museum's workshop.

One of the most challenging aspects was the boiler. The museum aimed to address the inefficiencies and safety concerns of the original design. They opted for a modern tubular boiler design, with steel tubes running through the water to maximize the heat exchange surface. This approach not only increased steam production efficiency but also enhanced safety.

The team incorporated historical elements, such as using brass tubes for the water flow and ensuring the boiler fit within the original space constraints between the Fardier's outriggers. They also added a safety valve and other modern safety features, respecting the historical design while ensuring operational safety.

Recreating the distributor and valve mechanism was another intricate task. The museum relied on drawings from the Industrial Inventory dating from the early 19th century and incorporated a spring mechanism to accelerate the valve's rotation. This dual-timing system, essential for the smooth operation of the engine, was meticulously reconstructed to match Cugnot's innovative design.

The steel chassis, wooden frame, and wheels were constructed to match the original specifications. The plans were drawn in inches, and hex bolts were used as they were historically accurate. The museum ensured that the various parts fit together logically and securely, replicating the robust construction techniques of the 18th century.

Testing and Refinements

Before using steam, the team conducted initial tests with compressed air. This allowed them to verify the motion of the pistons and the operation of the distributor without the risks associated with high-pressure steam. These tests revealed minor adjustments needed to ensure smooth and efficient operation.

Once the compressed air tests were successful, the team moved on to steam trials. The modern tubular boiler performed admirably, generating sufficient steam to power the vehicle. The Fardier replica moved smoothly, without the jerky motions or vibrations that plagued the original design. This success validated the team's design choices and construction methods.

Public Display and Educational Outreach

The completed replica of the Fardier de Cugnot was unveiled at the Tampa Bay Automobile Museum, now serving as a centerpiece that demonstrates the ingenuity and foresight of early automotive engineering. The museum has integrated the Fardier replica into its educational programs, teaching visitors about the history of steam power, the evolution of automotive technology, and the challenges faced by early inventors like Nicolas-Joseph Cugnot.
