The Brennan torpedo is often claimed as the world's first guided missile, but guided torpedoes invented by John Ericsson, John Louis Lay, and Victor von Scheliha all predate it; however, Brennan's torpedo was much simpler in its concept and worked over an acceptable range at a satisfactory speed so it might be more accurate to call it the world's first practical guided missile.[3].

Les démonstrations qu'il fait sont concluantes, mais des craintes de pannes du gyroscope empêchent l'adoption du nouveau système. He was born in Castlebar in 1852 to a hardware merchant, Thomas Brennan… Louis Brennan is regarded as one of the most accomplished engineers and inventors Ireland has produced. Louis Brennan (28 janvier 1852 - 17 janvier 1932), très honorable ordre du Bain, était un ingénieur mécanicien et inventeur irlando-australien. The complete installation at Pier Cellars still exists although it was greatly modified during later use for midget submarines.

Les torpilles contiennent des explosifs et la Royal Navy s'en sert pour défendre ses ports en Grande-Bretagne, en Irlande, à Hong Kong et à Malte. He demonstrated this by means of a cotton reel, with a pencil thrust through the hole in the centre. Cette section est vide, insuffisamment détaillée ou incomplète.

The guided missile was invented by Louis Brennan. Louis Brennan – inventor of the guided missile Louis Brennan was a mechanical engineer and one of Ireland’s most prominent inventors.

At the time the Royal Engineers - part of the army - was responsible for Britain's shore defenses, while the Royal Navy was responsible for its seaward protection. In 1883 an agreement was reached between the Brennan Torpedo Company and the government. Brennan invented the idea of a steerable torpedoin 1874, from observing that if a thread is pulled on a reel at an angle with suitable leverage, the reel will move away fr… The British Admiralty had meanwhile instructed Rear Admiral J. Wilson, the Commodore of the Royal Navy's Australian Squadron, to investigate the weapon and report back. C'était une sorte de torpille qui pouvair être tirée sous l'eau et contrôlée à distance à l'aide d'un fil. The installation at Fort Albert has been completely destroyed. Tests carried out in the Graving Dock at Williamstown, Victoria were successful, with steering proving to be reasonably controllable, although depth-keeping was not. Il s'intéresse aux transports et crée un système de monorail innovant qui est maintenu en équilibre grâce à un gyroscope[3]. The wire was attached to an engine to wind it in, rotating the drum that then propelled the vehicle away from its start point. Operational stations were established in the UK at Cliffe Fort, Fort Albert on the Isle of Wight and Plymouth.

Il a commencé sa carrière comme horloger et quelques années plus tard il est entré en apprentissage chez Alexander Kennedy Smith, un ingénieur civil et mécanicien renommé de la période.

Brennan decided to accept £40,000 as a quick answer to his financial worries but his business partner J.R. Temperley assumed control of the negotiations and demanded £100,000. It was designed to run at a consistent depth of 12 feet (3.7 m), and was fitted with an indicator mast that just broke the surface of the water; at night the mast had a small light fitted which was only visible from the rear.

It was used as a coastline defensive mechanism. At Fort Ricasoli the complex of buildings still exist and the slipway is mostly intact. After earlier experiments with a single propeller, by 1878 Brennan had produced a working version about 15 feet (4.6 m) long, made from iron boiler plate, with twin contra-rotating propellers. Manufacture of the Brennan torpedo finished in 1906. Brennan accepted this, but Temperley demanded a further £10,000 for the delay, and after some argument the War Office agreed, also agreeing to pay Brennan a sizable salary to act as production chief. The first seven were completed but out of the other eight only the one at Lye Mun was completed. By resting the ends of this pencil on two books and unwinding the cotton by pulling it from underneath he caused the reel to roll forward, the harder he pulled the faster the cotton unwound and the quicker the reel travelled in the opposite direction.

[6] Tomlinson [4] states that in 1874 while watching a planing machine worked by a driving belt, Brennan stumbled on the paradox that it was possible to make a machine travel forward by pulling it backward. Other stations included Fort Camden in Cork Harbour, Ireland, Lei Yue Mun Fort in Hong Kong and Forts Ricasoli and Tigné in Malta. 5, part 1 (1973). Brennan and Temperley soon afterwards travelled to Britain, where the Admiralty examined the torpedo and found it unsuitable for shipboard use. Four Brennan installations were added to existing fortifications at Fort Albert on the Isle of Wight, Cliffe Fort on the Thames, Garrison Point at the entrance to The Medway and at Fort Ricasoli at the entrance to the Grand Harbour at Malta. Louis Brennan (1852-1932), mechanical engineer, was born on 28 January 1852 at Castlebar, Ireland, son of Thomas Brennan and his wife Bridget, née McDonnell. At Lei Yue Mun the installation has been incorporated into a museum with a replica Brennan Torpedo on display. Brennan se rend en Angleterre en 1880 et présente son invention à de l'Office de la guerre.

Il fait breveter la « Torpille De Brennan » en 1877. Il a travaillé sur le développement de l'hélicoptère et du monorail, mais son plus grand succès a été d'inventer le premier missile guidé au monde[1]. Il passe quelques années à travailler sur son invention et reçoit une subvention de 700 £ du gouvernement de l'État de Victoria. Il a travaillé sur le développement de l'hélicoptère et du monorail, mais son plus grand succès a été d'inventer le premier missile guidé au monde [1]. However, traces of the installation at Fort Camden in County Cork are visible to this day. This page was last edited on 27 August 2020, at 22:18. At Fort Camden most of the installation still exists but is derelict. [5]:p28

In this way he was able to follow the track of the torpedo and steer it with a great degree of accuracy. Alexander Kennedy Smith was also working to obtain the Victoria government's backing for the project and raised the subject in the state's legislature on 2 October 1877. The Brennan torpedo was a torpedo patented by Irish-born Australian inventor Louis Brennan in 1877.

The plans for two installations at Dale Point and Great Castle Head, Milford Haven were drawn up but not carried out. There is also a display at Lei Yue Mun Fort in Hong Kong which shows a replica Brennan Torpedo with the side cut away so the workings are visible. https://fr.wikipedia.org/w/index.php?title=Louis_Brennan&oldid=164781640, Article avec une section vide ou incomplète, Portail:Biographie/Articles liés/Sciences, licence Creative Commons attribution, partage dans les mêmes conditions, comment citer les auteurs et mentionner la licence. In 1905 the Committee on Armaments of Home Ports issued a report in which they recommended the removal of all Brennan torpedoes from fixed defences due to their comparatively short range and the difficulty of launching them at night. La portée de ses torpilles n'est limitée que par la longueur du fil utilisé pour les guider, et elle peut atteindre jusqu'à 3 km. He was perhaps one of Ireland’s most creative minds, and the legacy of his remarkable inventions lives on today. Votre aide est la bienvenue ! Il a travaillé sur le développement de l' hélicoptère et du monorail, mais son plus grand succès a été d'inventer le premier missile guidé au monde. The Brennan torpedo was similar in appearance to more modern ones, apart from having a flattened oval cross-section instead of a circular one. The newly appointed Inspector-General of Fortifications in England, Sir Andrew Clarke, appreciated the value of the torpedo and in spring 1883 an experimental station was established at Garrison Point Fort, Sheerness on the River Medway and a workshop for Brennan was set up at the Chatham Barracks, the home of the Royal Engineers.
