Summary

Louis Brennan invented a steerable torpedo propelled by counter-rotating screws, a monorail locomotive with gyroscopic stabilisers, a gyroscopically balanced automobile, and helicopter designs. He arrived in Melbourne in 1861 with his family and was, at an early age, apprenticed to the engineer Alexander Kennedy Smith. In 1880 he took his steerable torpedo invention to the English War Office where the rights were purchased for £110,000 in 1886. He was awarded Companion of the Order of the Bath in 1892, and Honorary Member, Royal Engineers Institute in 1906. He did not return to Australia.

Details

From the "Australian Dictionary of Biography" Volume 3, (1969): "At 22 he invented for coastal defence a torpedo which was propelled by counter-rotating screws driven by the unwinding of two fine steel wires from internal drums and steered by the differential action of the two wires which were wound on to drums on shore or on shipboard by a steam engine of twenty horse-power. Among the advantages claimed were that the torpedo could be retrieved if it missed its mark. William Kernot, then lecturer in engineering at the University of Melbourne, made calculations on which a working model was based, its test performances in 1879 on Hobson's Bay 'exciting wonder and approbation'. This work was aided by a grant of £700 from the Victorian government."

The Gillingham Library, England retains the archive of his papers. It was in Gillingham that he successfully demonstrated a full size gyroscopically-balanced monorail on 10 November 1909.
