Aviation & Avionics, Thursday September 11, Period 2
As the students were filing in, Murdock was busy writing on the blackboard.
Flight was generally looked upon as an impossibility, and scarcely anyone believed in it until he actually saw it with his own eyes.
~Orville Wright.
To invent an airplane is nothing. To build one is something. But to fly is everything.
~Otto Lilienthal
He turned around and faced the class. "You may have heard of the first name, but probably not so much the second one. Though many people know who the Wright Brothers are, there were many who came before them, paving the way into the skies."

Re: Lecture!
In April 1841, he patented an improved light-weight steam engine, and with John Stringfellow in 1842, he designed a large passenger-carrying steam-powered monoplane, with a wing span of 150 feet. He named it the 'Henson Aerial Steam Carriage'. He received a patent on it in 1843 along with Stringfellow. Henson, Stringfellow, Frederick Marriott, and D.E. Colombine, incorporated as the Aerial Transit Company in 1843 in England. Despite their efforts, the designs were flawed with Stringfellow's ideas centered around monoplane and triplane models and Henson's ideas centered around an underpowered steam-powered vehicle. The two achieved popular attention, as Stringfellow did achieve the first powered flight, in 1848, in a disused lace factory in Chard, with a 10 foot (3m), steam-driven flying machine.
Otto (http://www.lilienthal-museum.de/olma/eotto.htm) Lilienthal (http://www.flyingmachines.org/lilthl.html) was a pioneer of human aviation and was the first person to make repeated successful gliding (http://aerostories.free.fr/precurseurs/lilien/page2.html) flights. He followed an experimental approach first established earlier in the century by Sir George Cayley. A sketch toward a second hang glider in 1891-1892 involved a triangle control frame with a complex basebar that would lead to lower double kingposting while the apex of the triangle would serve as a single kingpost; his filing of a U.S. Patent in 1894 directed pilots to grip the 'bar' for carrying and flying the hang glider. The A-frame of Percy Pilcher and Otto Lilienthal echoes in today's control frame for hang gliders and ultralight trike aircraft. Working in conjunction with his brother Gustav, he made over 2,000 flights in gliders of his design starting in 1891 with his first glider version, the Derwitzer.
Lilienthal did basic research in precisely describing the flight of birds, especially of storks, and used polar diagrams for describing the aerodynamics of their wings. He then made many experiments in an attempt to gather reliable aeronautical data.
His unpowered gliders were controlled by changing the centre of gravity by shifting his body, much like modern hang gliders. However they were difficult to maneuver and had a tendency to pitch down, from which it was difficult to recover. One reason for this was that he held the glider by his shoulders, rather than hanging from it like a modern hang glider. Only his legs and lower body could be moved, which limited the amount of weight shift he could achieve.

Didn't mean she wasn't taking copious notes. They were interesting and crazy, at least.

However, he worked in partnership with younger experimenters, including Augustus (http://www.flyingmachines.org/chan.html) Herring (http://www.earlyaviators.com/eherring.htm) and William Avery. In 1896 and 1897 Chanute, Herring and Avery tested hang gliders based on designs by German aviator Otto Lilienthal, as well as hang gliders of their own design, on the shores of Lake Michigan. These experiments convinced Chanute that the best way to achieve extra lift without a prohibitive increase in weight was to stack several wings one above the other. Chanute invented the 'strut-wire' braced structure that would be used in all biplanes of the future.
Herring, who sometimes is claimed by Michigan to be the first true aviator of a motorized heavier-than-air aircraft, had by 1893 built and crashed a full sized glider. Herring built a Type 11-monoplane glider in 1894 based on Otto Lilienthal‘s 1893 German patent. He soon would take up his own aviation experiments and in 1896, Herring applied for what was possibly the earliest patent of its type in the USA, a patent for a man-supporting, heavier-than-air, motorized, controllable, 'flying machine'. Herring's glider was difficult to steer and because of his two-cylinder, three-horsepower compressed air engine, could operate for only 30 seconds at a time. He was considered having only continued the tradition of hang-gliding, and is thus not considered a candidate for the first flight.
Samuel (http://www.flyingmachines.org/lang.html) Langely (http://www.sil.si.edu/ondisplay/langley/intro.htm) attempted to make the first working piloted heavier-than-air aircraft. His models flew, but his two attempts at piloted flight were not successful. Langley (http://www.historynet.com/samuel-langley-aviation-pioneer.htm) began experimenting with rubber-band powered models and gliders in 1887. He built a rotating arm, functioning similar to a wind tunnel, and made larger flying models powered by miniature steam engines. His first success came on May 6, 1896 when his Number 5 unpiloted model flew half a mile after a catapult launch from a boat on the Potomac River. Though insufficiently controlled, a key requirement in the development of flight, aviation historians consider this to be the world's first sustained flight by a powered heavier-than-air craft.
Samuel Langley built a unmanned model of an airplane that included a steam-powered engine. In 1891, his model flew for three-fourths of a mile before running out of fuel. Samuel Langley received a $50,000 grant from the United States War Department to build a full sized aerodrome, the Aerodrome A with a gas powered engine. In 1903, it crashed immediately after being launched from a house boat over the Potomac River as it was too heavy to fly. Samuel Langley was very disappointed and he gave up trying to fly.

Talk to the teach!
OOC
and that's after I trimmed some bits outDon't worry about having to know all or go through all the things, or anything of that sort.
I'm just an
