Hi,
I still forgot one: Jacob Brodbeck, 20 September 1865 http://www.historynet.com/ahi/bljbrodbeck/ (I have copied the text at the end of that posting) the german museum in Munich has plans of that airship. bye m. vanselow On Thu, 18 Dec 2003 00:31:55 +0100, vanselow wrote: On Tue, 09 Dec 2003 15:13:34 GMT, "Steven P.

Henri Giffard, 24 September 1852 www.skytamer.com/famous/1800.htm the borther Wrights were just be filmed doing that, and they were USamercians. bye m. vanselow --------------------- Brodbeck was born in the duchy of Württemberg, Germany, on October 13, 1821. After attending a seminary in Esslingen, he taught school in Württemberg for six years before sailing for Texas with his brother, George, on August 25, 1846. Always interested in mechanical things, Jacob attempted to build a self-winding clock while still in Germany. In March 1847 he moved to Gillespie County, Texas, which already had a substantial number of German residents, to become the second local schoolteacher. In 1852 he became a U.S. citizen and married one of his former students. For 20 years Brodbeck worked on his most cherished project, an "air ship." He wrestled with the 19th-century problem of how to get sufficient power aboard his craft, a power source that would not be too heavy to lift a plane. The internal combustion engine -- which later provided a lightweight power plant for the Wrights -- had not yet been invented, and the steam engine, at that time the most modern source of power, weighed so much that it seemed unlikely to be able to lift itself, much less any plane in which it might be housed. So Brodbeck turned to the most efficient lightweight source he knew, the spring. Relying on his knowledge of spring-driven clocks, in 1863 Brodbeck built a small model with rudder, wings and propeller that actually flew, powered by coiled springs. That same year he moved to San Antonio to work as a piano tuner and schoolteacher, and to be closer to sources of fundraising for his pet project. He showed his model "flying toy" air ship at various local fairs, where it was greeted with amazement and enthusiasm. Encouraged by the success of the model, Brodbeck set about raising funds to build a full-size version capable of carrying a man. He found a few backers who bought shares in his project after he promised to repay them within six months of selling patent rights to his machine. His principal supporter was Dr. Ferdinand Herff, a San Antonio physician who encouraged the inventor to continue to work on his air ship and lent him space on his farm to try out his planes. According to Jacob Brodbeck "Reached for the Sky" in Texas by Brodbeck's great-granddaughter, Anita Tatsch, on August 7, 1865, Brodbeck wrote a fundraising article that described his project and the parts of his proposed air ship as follows: Every shareholder will receive a certificate, securing to him a proportionate interest in proceeds of the enterprise. I will give a few ideas indicating generally the character of the air ship, and what it will be able to accomplish. The air ship consists of three main parts: 1. The lower suspended portion, formed like a ship with a short prow to cut the air; it serves to hold the aeronaut, and also the power of producing engine with all the steering apparatus. This portion is shut up all around to prevent the rapid motion from affecting the breathing of the man within. In this, as low as possible, lies the center of gravity of the whole structure, so as to steady the motion. At the back end of the ship, there is a propeller screw which will make it possible to navigate in the water, in case by any accident the aeronaut should have to descend while he is above water. In this case, the ship can be detached from the flying apparatus. 2. The upper portion, or flying apparatus, which makes use of the resistance of the air, consists of wings, partly movable, partly immovable, presenting the appearance of horizontal sails, but having functions entirely different from the sails of vessels. 3. The portion producing the forward motion consists of two screws, which can be revolved with equal or unequal motion, as to serve the purpose of lateral steering, or of wings of a peculiar construction. The preference to be given to one or the other depends on the nature of the motive power. Another apparatus regulates the ascending motion. The material is so selected as to combine the greatest strength with the least weight. When the air ship is in motion, the aeronaut has in each hand a crank, one to guide the ascending and descending action, the other the lateral steerage. Immediately in front of him is the compass, while a barometer with a scale made for the purpose, shows him the approximate height. Another apparatus, similar to the ball regulator of a steam engine, shows him the velocity, as well as the distance passed over. It is self-evident that the speed of the air depends upon motive power and on the direction of the winds; according to my experiments and calculations it will be from 30 to 100 miles per hour. According to Brodbeck's logic, whereas his spring-powered toys came to earth as the spring unwound, the pilot of the air ship would be in a position to rewind the spring, thus providing a continuous source of power for the propeller. But how wrong he was! Brodbeck failed to take into consideration one small but vital factor -- it is impossible to rewind a spring while it is unwinding. Brodbeck constructed his flying machine, but what happened next is unclear. There are several conflicting versions. One says that Brodbeck made his first flight in a field three miles east of Luckenbach, a hamlet in Gillespie County, Texas, on September 20, 1865. The craft reportedly rose 12 feet in the air and traveled about 100 feet before the spring unwound completely and the machine crashed. Another report says Brodbeck's first flight was in a field belonging to Dr. Herff near San Antonio. Yet another account says the flight took place in 1868, not 1865. The most intriguing version claims that Brodbeck crated his plane and took it to Washington, D.C., where he flew it off a three-story building. It was also reported to have had a steam engine, not a coiled spring. The air ship supposedly hung in the air and maintained an even flight for a few seconds, then gradually settled to the ground. The wings folded over and severely crushed Brodbeck, who was said to have spent several months in a Washington hospital. All versions of the flight test, however, shared the same sad conclusion: The air ship fell to the ground in a splintering crash that totally destroyed the craft. After this setback, Brodbeck's backers refused to put up money for a second attempt. Undaunted, Brodbeck went on a fundraising tour of the United States but failed to find enough new investors. In addition, some of his blueprints and plans were said to have been stolen. Another story has it that his disgusted wife threw his papers in a creek. Brodbeck finally returned to Texas to live on his ranch near Luckenbach, where he tinkered with an ice-making machine until his death in 1910, seven years after the Wright brothers' first flight in Kitty Hawk, N.C. Several questions inevitably arise about all of these conflicting accounts. One concerns the coiled spring used for power. Why did Brodbeck think he could rewind it as it was unwinding while airborne? And why didn't Brodbeck bother to patent his air ship? His family claimed he did take the plans to the U.S. Patent Office and was issued a patent on June 27, 1865. However, a check of the Department of Commerce by a researcher some years ago showed that no such patent had been issued. No drawings or blueprints of Jacob Brodbeck's craft are known to have survived, so of course, his aviation achievements remain shrouded in mystery. Was he or wasn't he the first man to fly in a heavier-than-air craft? For more great articles be sure to pick up your copy of Aviation History. |

Vanselow,
If you would read the text, you would know, that people have rebuild the flyer of Whitehead (Weisskopf). Well, if YOU would research that, you would find that they didn't rebuild it. The built something similar looking with a much more powerful engine. A barn door will fly, if the attached engine is strong enough... -- Thomas Borchert (EDDH) |

That replica was cheated to a significant degree and doesn't truly represent what Whitehead claimed to have flown - not least in its powerplant. And it certainly did not have control in all three axes - you do understand what that means, don't you? |
