Generic chapter on steam-powered engines.

-We have seen many engines running on steam, from the Stringfellow and Ader to the Basler.

-But even more has been said.

-As we can see in a photograph taken by Gary Brossett of the AEHS, at the Austin Museum at Warner Robins Air Force Base (AFB), Georgia, USA.

"Steam-Powered Aircraft Engine"

From Appendix 6: Some additional information has been obtained regarding the steam engine listed in the main text, which is also listed as a UFE (Unidentified Flying Engine). Although it is supposedly built between 1905 and 1908, its manufacturer is unknown.

-This particular steam engine was made in the United States and is now on display at the Warner Robins Air Force Base (AFB) Museum, Georgia.

Specifically, it was loaned by the Savannah Science Museum and restored by Bob Davis of Arkansas.

It produced 70 HP at 200 psi, weighing 100 lbs with its boiler, pumps, and propeller.

“The steam engine at the Robins Museum”

It has three radial cylinders, and this particular engine model has been reduced to 1/2 size for collectors. It runs on compressed air, with the utmost detail.

“Scale-down models of the engine”

And below is a detail of the inner workings of the crankcase, showing the pistons and the crankshaft assembly, similar to those found in radial internal combustion engines.

“Internal Detail”

From Appendices 5/6/7: The development and exploitation of steam to power devices continues, so we have received a new pair of systems (one of them a duplicate).

-These are new V-engines. In fact, they could be barrel- or revolver-type engines “folded” in half.

“A Steam V-engine from the early 1970s”

-When one side rotates, the double pistons connected at an angle force the other side to rotate.

-The pistons slide from one drum to the other, causing the rotation with this movement.

- A cock acts as a throttle control. This geometry is repeated in the following one from 1974.

"Another V-shaped steam engine" (PiP)

- And the next one, based—yes—on the engines that appear throughout this publication, is a barrel type with inclined sliding plates.

- More easily understood in operation is the so-called Elliptocline, rated at 60 HP, and considerably more if overloaded. The following drawing by Popsci presents it very descriptively.

"The Steam Elliptocline engine" (PiP)

- An interesting steam engine from 1932 that appeared in Modern Mechanix magazine is the one we are now providing.

- In fact, it was only a project, but it was original in that the engine drove a three-bladed propeller at the roots of which were the three actuating cylinders, powered by steam.

“The Great Lakes Engine”

- It was another model from the Great Lakes Aircraft Corp. (see Main Text).

- An imaginative steam-powered German seaplane. It had two pontoons, each with an engine and boiler. The smoking chimneys, reminiscent of a ship, are striking. It was the mid-1930s, taken from Popsci (PiP).

“Drawing of the steam-powered passenger airplane”

- In 1874, Felix Du Temple presented his flying machine with a propeller initially driven by a clockwork spring, which, optimally, was wound and released, making the propeller itself the regulator.

- But he soon decided—along with his brother Louis—to enhance his machine with a steam engine, although it is unknown for certain whether it ever flew.

- Tests were conducted on a descending ramp.

"Du Temple's Apparatus" (PiP)

-Among the many steam-powered designs, another interesting one, dating back to 1870, was a flapping-wing ornithopter attached to a balloon basket.

- It was designed by P. Piraud. It was steam-powered according to the arrangement shown in the below illustration.

"Piraud's Steam-Powered Ornithopter"

A small steam engine was discovered on a Russian blog, used on a model, as seen in the below illustrations.

"Steam Microengine"

- It was a rustic construction, the gearing resembles clockwork.
