LEARNING AND LITERATUREThis was a learning day. I went to the
Chataqua lecture at Buffalo Gap Village, run by
McMurry University professors, where the president of
McMurry University, Dr. John Russell, gave a lecture advertised as THE HISTORY OF AVIATION, but he changed the title to be notable events in aviation. All of his degrees are in Aerospace engineering. His Bachelor's focused on propulsion, his Master's on structures and materials and his Doctorate on aerodynamics. He started with a slide showing the helicopter designed by
Da Vinci in the 14
th Century but didn't fly. He was focusing on the six aircraft that were keys in the development of aircraft. He reviewed the manned gliders and pioneers in designing aircraft. Otto
Lillenthal was killed flying his glider but contributed to the knowledge of how to steer gliders.
Samuel Langley had the first powered airplane but it didn't fly even though it was funded by the government. While he was highly educated the Wright brothers were bicycle mechanics who figured out how to warp wings to gain better control so the first major aircraft was their
Flyer. He discussed the early wood and fabric "organic airplanes" built for WWI that had problems with the materials deteriorating and that led to his next notable airplane, Junkers J1, that was made of iron but had a power plant large enough to fly it faster than others. It had a maneuverability problem but led to thinking about metals and aluminum was chosen. His third airplane was the Boeing 247 (I think the number is right) that was built for
UAL for passengers. It was eclipsed by the DC-3 built for TWA by Douglas. That airplane is still flying today. He then went into an explanation of the design of wings showing the development of airfoils by
NACA and explained how
theoreticians and experimenters got together to understand the aerodynamics and how to build better wings. He showed the equations for drag and how as airplanes approached sonic speeds the drag went to infinity by the equations. His next airplane was the P-51 with a wing that allowed higher speeds. But to go supersonic he showed that a German engineer in 1935 gave a paper showing that swept wings would permit supersonic speeds. Many years later he was brought to NASA after WWII and helped develop the
swept wing aircraft that now are the shape of all modern airliners.
He asked for other suggestions and I supported my B-58 that was the first airplane to cruise at Mach2. But it didn't last long because General
LeMay wanted a long range bomber that could fly to Japan and back. Russell is an exciting lecturer that is animated and loves his subject. I hope that he continues to offer such lectures.
I literature I am reading three books at the same time. I have been reading Edward Murray's book of short stories and just finished his story of First Calf about an old rancher near me who saved a cow and calf from a wildfire. It was too close to home. I am also reading Bob Favor's MY RANCHING DAYS before he gives his talk May 4 at our Meet the Author program. I heard him speak in Abilene and bought his book but hadn't opened it. He reviews his growing up days farming and ranching and tells about his stint in the Navy and as a Highway Patrolman before being accepted as a Ranger. His Ranger stories are varied and interacted with historical events, particularly the political scene along the border. He will tell us stories that aren't in his book. The other book I started is one I bought at the Texas Folklore Society. Paul Patterson wrote a romance called THE SHEEPHERDER that I have just started. It is humorous and an interesting read.
Of course preparing for Sunday School I am reading Joshua and tomorrow we will discuss why the Lord listened to Joshua and stopped the world from rotating for a day. Many cultures have the story of the long day, but modern people can't believe it. Should make for a good discussion.
