Cowling, what i mean is that theres a tight figtting metal covering and allows the air to flow over more efficiently. So, mark burket of the spanish Swiss Company has designed a very important series of automobile engines in the prewar era. He adapts this to the aeronautical application by taking two of his inline four engines, makes it into a v8, and what he does thats very unique is instead of having separate cylinders attached to the crank case, he casts a row of cylinders out of a solid piece of aluminum. And he has cooling packagssages those aluminum blocks that allows improved cooling and more power. So instead of a rotary engine, you know, doing 110, 120 horsepower, youre looking at 200 or 220 horsepower with these engines by the time theyre introduced in the spad xii. Theres always a technological pushpull over the western front in world war i, in which the germans have an advantage with their thick air foiled tubular steel fuselaged aircraft like the folker d 7 that you can se
Prizewinning flight, but it was the recordbreaking flight. And so they went to the trouble to reinstall the dented engine nozzle on it. Our next stop will be sky lab, and were going to look at that because it is one of the original artifacts on display here since before this Museum Opened. Sky lab is so large, it was brought into the museum before the building was closed out. Now im standing in front of a model of sky lab thats as tall as i am but the real sky lab orbital work station behind me absolutely dwarfs the model and me. It reaches from the floor up into the sky lights of this building, two stories tall. Sky lab was the United States first space station, placed in orbit in 1973 and in 1973 and 74, three different nasa astronaut crews spent time aboard it. Three men at a time, one group was there for one month. Another group for two months, and the third group for three months. The whole point of the sky lab missions was to get some experience in living and working in space. Wh
The moon. So its actually fairly flimsy in some areas. The legs are obviously strong and mount for the rocket engine is strong but the craft itself and particularly the crew module or crew cabin was really fairly spartan. It had two windows. Neil armstrong had command of the craft during the final descent to landing. Both of them were standing. They were fully suited in their space suit and they pretty much filled that interior volume in that position with those space suits on. It was not really designed for comfort. It was designed for the purpose of landing, giving the crew an exit so they could spend a couple of hours on the surface of the moon and then launching again along with their precious cargo of lunar soil and rocks to bring back home to demonstrate that they had been there and to have those materials for scientists to begin analyzing and better understand the moon. Its also amazing to think that the Computing Power required in that day to send these craft to the moon and pr

University. Keith has long experience in the historical profession. He started off as a seasonal historian, actually as a volunteer at kennesaw National Military park when he was a teenager. A teenager. And during that time, he also did Extensive Research in georgia archives. There simply is not another person who knows more about georgia during the civil war than keith bohannon. He finished his ph. D. At penn state, started under Gary Gallagher, who then moved on to the university of West Virginia and then mark nealy was keiths adviser. To the right of keith is katy meier. She is an assistant professor she just received her promotion excuse me, i just said assistant, i meant to say associate professor at virginia commonwealth university. Katy is a graduate or i should say a student of Gary Gallagher at the university of virginia, where she completed her dissertation, became a book called natures civil war and its published by university of North Carolina press. If any of you have any
