Introduction
T his book studies the use of steam as a method of propulsion in aviation, and the reasons behind the adoption of steam engines to provide lift and motion in the air. There is also information on the remaining artifacts in various museums around the world.
From a historical point of view, the use of steam engines in aviation was a necessity, for at first, during the nineteenth century, this type of power unit was the only source of energy available for the purpose. Some incredible lightweight machines were created by individuals such as John Stringfellow (1799 1883), and by firms like Ahrbecker, Son & Hamken of Stamford Street in London, during that time. Later, the steam engine became the preserve of aviation enthusiasts who were determined to demonstrate that aircraft could be made to fly successfully using external combustion engines (electricity and compressed air were also utilised). One of these enthusiasts was William J. Besler of the Besler Corporation of California, who took off from the San Francisco Bay Airdrome on 20 April 1933 to make a few circuits of the airfield in a Travelair biplane which was fitted with a monotube steam plant of his design. A number of pioneer experimenters put their minds to the problems of flight generally on the boundary of the nineteenth and twentieth centuries and most of these regarded the steam engine as the only real source of power to make their aircraft achieve sustained flight.

The Somerset County Museum, Taunton
- i) INV.No 59/2003/1 The Stringfellow airship engine
- ii) INV.No 59/2003/2 The boiler for the Stringfellow airship engine
These two items were donated by John Stringfellows grandaughter, Mrs Marshall in 1940. They were cleaned and conserved by H.C. Stevens of Avimo Ltd, Instrument makers of Taunton, in 1941 and an account of this restoration is given in the Journal of the Somerset Archaeological & Natural History Society, July 1941. There is a box of documents concerning John Stringfellow and Sir Hiram Maxim in the Local Studies Library in Taunton.
