Air Power IV



Air Power IV
The Men, Machines, and Ideas Which Revolutionized War from Kitty hawk to Iraq.
By Stephen Budiansky
A Book Report by Larry Eicher 

World War II was preceded by The Spanish Civil War, July 17, 1936 – April 1, 1939.  The conflict proved to be timed just right for the countries building up for WW II to use it as a testing ground for their own forces.  They could try out their equipment and men under combat conditions.  Mussolini’s Italy and Nazi Germany supported the Spanish Nationalists.  The Spanish Republicans were supported by the Soviet Union.
WW II began in September 1, 1939 when the Germans attacked the Polish who were unable to defend themselves.  The Nazis attacked with blitzkrieg, aka “lightning War.” They had radio contact between the elements of their force and they moved quickly before the Polish knew what to do.
As I mentioned previously in “Air Power” III the war began with many technological advancements.  The biplane was almost gone.  Monoplanes were the way to go.  Bombers began the war using the best bomb site from the end of WW I.  Fighters were fast enough to keep up with the bombers even though the bombers didn’t know they needed them yet.  Air Power advocates knew bombs could sink ships.  The Army and Navy were still feuding.  Air Craft carriers gradually began replacing Battleships.  That process sped up from Pearl Harbor onward.  That was a difficult change to accept for many!

Mitsubishi A6M2 Zero
At the beginning of WW II, the Japanese zero was the best fighter in the world.  The German ME 109 was about equal to the British Spitfire.  The 109 had an advantage over early American fighters because it was fuel injected and the engine would keep running in a dive.  The carbureted American fighters would lose engine power in a dive. 

Supermarine Spitfire
As the war in Europe moved on, the bomber command decided fighters were needed to protect the bombers since their armament was inadequate.  The Allies were losing many bombers.  
Mr. Budiansky covers details of WW II related to Men, Machines, and Idea as the title suggests.  He provides many details beyond the scope of this book report.  It is called World War II for good reason.  There were theaters of operations all over the world, obviously.  Among many the major ones were: The European Theater, The Mediterranean Theater, African and Middle East Theater and the Pacific Theater.
One development of technology has been a thread throughout the book, even in other wars.  Bombardment accuracy has posed a problem since the beginning of aviation.  The United States championed Daylight Precision Bombardment which was anything but accurate at least through WW II.  The Norden Bomb Sight was supposed to take Bombing accuracy a new level but that level was not good enough.   I just have to use a word Budiansky did not use is his book.  Idealism was at the center of the controversy.  When reality in bombing could not live up to the ideal, The Idealists broke from reality to called the benefits of bombing morale bombing  There are two words he uses in this area.  You have to pay attention to their use.  They are “moral” and “morale” It was considered by many, Worldwide, to be immoral to kill citizens with bombing.  The word, “moral”, morphed into “morale” as the debate about bombing accuracy continued.  Inaccurate bombing became “morale” bombing as time went on and the problem of bombing accuracy was not resolved.  The idea was to cause the civilian population to demand the threat be removed by surrender.  Since bombing accuracy was unattainable, drop the bombs indiscriminately and they will affect morale of the populace.  The workers might be unable to concentrate on weapon production because of the bombing.  I can tell you he describes the solution to accurate bombing later in the book.

Where the European theater was configured around the aerial and infantry fighters at the beginning, War in the Pacific was fought with submarines, carriers and aircraft at the beginning.  The Pacific fleet had been decimated at Pearl Harbor.  The Carriers were undamaged since they were absent.  As time passed both theaters saw advancements and changes.  The full story is too complex to be contemplated in this context.  The story has been much told.
By the end of the war in the European Theater, the North American P-51 had emerged and accompanied the bombers all the Way to Berlin.  The Germans had introduced weapons no one had dreamed of previously such as V-1’s buzz bombs, V-2’s, rockets and a jet power fighter, the ME 262, not to mention a rocket powered fighter in development, Me 163.

Messerschmitt ME 262A
By the end of the war in the Pacific Theater the Boeing B-29 Super Fortress had emerged as the ultimate air weapon to deliver the Atom Bomb to Japan.  Japan had released Suicide Pilots on the world.  The USA had a total of twenty-seven Aircraft Carriers at the end.  Naval aviation was a definitive factor at the end of the war.

Air Power by Stephen Budiansky tells the story in much more detail.  It is well worth reading in my opinion.

Air Power III


Air Power III
The Men, Machines, and Ideas Which Revolutionized War from Kitty hawk to Iraq.
Air Power
By Stephen Budiansky



The end of the Great War brought changes in the participating countries. Germany, having lost the war had gained much knowledge about making planes and their use. Even though they had to turn them over to the Allies, the winners, they had much knowledge to carry forward with them to the next war.

The other war participants, the allies, had to cycle down their war production and try to recover their economies. The war had seen advances in construction and usage of air power. Having entered the war as a fledgling part of the fighting force, the proponents of air power had to fight to keep it viable in the ensuing years. The popularization of civil air travel was one factor moving forward aviation. Many improvements in the machines and process, such as artificial horizon, gyrocompass, flying down, through fog to the runway while following a radio beam. These are things the RFC did not get to in the interwar period. Jimmy Doolittle was a central figure in developing flying with the use of instruments. Artificial horizon, Gyro compass, Auto pilot are some of the instruments making this possible. This method is used when the pilot cannot view the ground for navigation.

The British found that they could use air power to regain power in their empire. Its use caught on and saved lots of money in the process. Air power gained prestige and popularity in the process. Budiansky names the key figures in air leadership. In his opinion they were not the best people for the job but things progressed anyway.

The French had bourn the load of the manufacturing during the war and, of course, things needed to be throttled back after the war.

In the USA several figures took center stage creating mayhem and agitation as well as moving things onward. Mitchell and Arnold being strong supporters of air power came to the forefront during that interwar era. Mitchell was so outspoken, vehement and abusive of leadership not to mention media manipulative that he was removed from leadership and demoted to Texas and ground operations. He was eventually court-martialed for insubordination. With all his negative activity, he put air power solidly into contention against the navy. He arranged a combat trial to show how the AAC could sink battleships. Many Naval devotees disagreed on that point! He used a trick to get the navy in the public eye so they would have to agree to the experiment.

The Navy had an obsolete German Battleship, Ostfriesland from the war. The experiment started out as a scientific experiment but later it became a push to get it to sink. Mitchell ignored his agreement with the navy on procedure. He had his bombers line up to bomb the ship without time for observers to go aboard and assess damage. He had a way of crossing everyone who disagreed with his way.

Arnold was almost court-martialed for supporting Mitchell in his endeavors.

Another technological advancement which should be mentioned was the shape of the wing. This occurred at The University of Goettingen, in Lower Saxony, Germany and was aerodynamic research relating to the airfoil of the wing. Von Karman did the research which showed they needed to fill the joint between wing and fuselage to smooth airflow. Ludwig Prandtl did the research at Goettingen which showed that a thicker airfoil generated less drag than did thin ones. As a side benefit this allowed the wings to be self-supporting, not requiring wires. The Fokker D. VII had this airfoil and no wires.

Another advancement, the variable pitch propeller was useful because the blades, wings in rotation, could be rotated adjusting their angle of attack to the oncoming air. I have thought of the concept as being a gear shift for the airplane. At takeoff the blades would be adjusted to take a small bite, having high speed of rotation. At cruising speed the blades would be adjusted to take a large bite, having a lower speed of rotation. The Douglas DC 3 and Boeing 247D were among the first aircraft to utilize this advancement. The feature was soon designed to make the pitch changes automatic.

Ground Hog Day



Ground Hog Day!
I can’t seem to ignore February 2 each year.

Marmota Monax

 Those of us who lived on the farm do not hibernate like the ground hog in the winter but we did go inside.  Maybe we were hibernating after all.  Anyway, we made a big deal of Ground Hog Day when I was growing up.  I was out of college before I decided that it was just a myth like Santa Clause and it didn’t matter if he saw his shadow or not.  (I knew about Santa much sooner in life.)  It’s the collective unconscious of humans who hate winter and wish for spring.  I learned in later years not to hate winter as badly.  I could get outside with my camera and that was great.  I decided that the city and the brown snow made me hate winter.  I used to and still do love looking for signs of spring from February 2 on, though.
