Charles Renard
Charles Renard (1847–1905) born in Damblain, Vosges, was a French military engineer. Airships After the Franco-Prussian War of 1870-1871 he started work on the design of airships at the French army aeronautical department. Together with Arthur C. Krebs and his brother Paul, in 1884 he constructed '' La France'', which made its maiden flight on 9 August 1884 at Chalais-Meudon, making a 23-minute circular flight. This was the first time that a flying machine made a flight which returned to the place of take-off. It was later exhibited at the Paris Exposition Universelle (1889). Preferred numbers Ca. 1877 he proposed a now widely used system of preferred numbers known as Renard numbers that was later reportedly published in an 1886 instruction for captive balloon troops, named after him in the 1920s and finally became international standard ISO 3. It helped the French army to reduce the number of different balloon ropes kept on inventory Inventory (British English) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Krebs
Arthur Constantin Krebs (16 November 1850 – 22 March 1935) was a French officer and pioneer in automotive engineering. Life Collaborating with Charles Renard, Krebs piloted the first fully controlled free-flight made in the French Army airship '' La France'', which was designed in 1884. The flight covered in 23 minutes. The flight landed back at its starting point. On its seven flights the ''La France'' dirigible returned five times to its starting point. Krebs and Renard shared the 1886 Ponti prize of the French ''Académie des sciences'' for their contribution to aerostation. Krebs inspired Jules Verne. In Verne's 1886 novel ''Robur The Conqueror'', he writes of "the striking experiments of Captain Krebs and Captain Renard". In 1888 Krebs and Gustave Zédé designed the first modern French submarine, the '' Gymnote''. The submarine was fitted with the first naval periscope and the first naval electric gyrocompass. The latter allowed the ''Gymnote'' to force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Standard
An international standard is a technical standard developed by one or more international standards organizations. International standards are available for consideration and use worldwide. The most prominent such organization is the International Organization for Standardization (ISO). Other prominent international standards organizations including the International Telecommunication Union (ITU) and the International Electrotechnical Commission (IEC). Together, these three organizations have formed the World Standards Cooperation alliance. Purpose International standards can be applied directly or adapted to meet local conditions. When adopted, they lead to the creation of national standards that are either equivalent to or largely align with the international standards in technical content, though they may have: (i) editorial variations, such as differences in appearance, the use of symbols, measurement units, or the choice of a point over a comma as the decimal marker, and (ii) va ...

Airship Designers
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1905 Deaths
As the second year of the massive Russo-Japanese War begins, more than 100,000 die in the largest world battles of that era, and the war chaos leads to the 1905 Russian Revolution against Nicholas II of Russia (Dmitri Shostakovich, Shostakovich's Symphony No. 11 (Shostakovich), 11th Symphony is subtitled ''The Year 1905'' to commemorate this) and the start of Revolution in the Kingdom of Poland (1905–07), Revolution in the Kingdom of Poland.

Poncelet Prize
The Poncelet Prize () is awarded by the French Academy of Sciences. The prize was established in 1868 by the widow of General Jean-Victor Poncelet for the advancement of the sciences. It was in the amount of 2,000 francs (as of 1868), mostly for the work in applied mathematics. The precise wording of the announcement by the academy varied from year to year and required the work be "in mechanics", or "for work contributing to the progress of pure or applied mathematics", or simply "in applied mathematics", and sometimes included condition that the work must be "done during the ten years preceding the award." 19th century Source: * (1868) Alfred Clebsch * (1869) Julius von Mayer * (1870) Camille Jordan * (1871) Joseph Boussinesq * (1872) Amédée Mannheim, "for the general excellence of his geometrical disquisitions." * (1873) William Thomson, "for his magnificent works on the mathematical theory of electricity and magnetism." * (1874) Jacques Bresse, "for his work in applied m ...

Daimler Company
The Daimler Company Limited ( ), before 1910 known as the Daimler Motor Company Limited, was an independent British motor vehicle manufacturer founded in London by Harry John Lawson, H. J. Lawson in 1896, which set up its manufacturing base in Coventry. The company bought the right to the use of the Daimler name simultaneously from Gottlieb Daimler and Daimler-Motoren-Gesellschaft of Cannstatt, Germany. After early financial difficulty and a reorganisation of the company in 1904, the Daimler Motor Company was purchased by Birmingham Small Arms Company (BSA) in 1910, which also made cars under its own name before the Second World War. In 1933, BSA bought the Lanchester Motor Company and made it a subsidiary of the Daimler Company. Daimler was awarded a Royal Warrant of Appointment (United Kingdom), Royal Warrant to provide cars to the British monarch in 1902; it lost this privilege in the 1950s after being supplanted by Rolls-Royce Limited, Rolls-Royce.

Darracq And Company London
STD Motors, formerly Darracq & Company, was a French manufacturer of motor vehicles and aero engines based in Suresnes near Paris. The French enterprise, known at first as A. Darracq et Cie, was founded in 1896 by Alexandre Darracq after he sold his Gladiator Bicycle business. In 1903 Darracq sold the business to A Darracq and Company Limited of England, taking a substantial shareholding himself. Darracq continued to run the business from Paris until retiring to the Côte d'Azur in 1913 following years of financial difficulties. He had introduced an unproven unorthodox engine in 1911 which proved a complete failure yet he neglected Suresnes' popular conventional products. In 1920, A Darracq & Co was rebranded as STD Motors. In 1922 the Darracq name was dropped from all products, the Suresnes business was renamed Automobiles Talbot and the Suresnes products were branded just Talbot. The Suresnes business continued, still under British control, under the name Talbot until 1935 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
