Hughes H-4 Hercules Duane S. Deeter Southeastern Oklahoma State University Abstract Howard Hughes was awarded a large military contract to build a large transport aircraft to help with sending supplies overseas during WWII. Requested in 1942 by the U.S. Government, the aircraft was to be designed as a troop and cargo aircraft. Supplies were getting extremely delayed due to the German Navy’s U-Boat fleet destroying anything in range. The project was doomed from the start. One of the main issues was the shortage or material.
However, the NTSB found that the crews were very close into over timing their duty hour’s limitation. The NTSB then declared human issue was indeed a big major issue that caused the flight 1420 went wrong on June 1st, 1999 (Wiegmann, 2001). The NTSB then conducted an investigation using the Human Factor Analysis and Classification System. The investigation was split into finding the human factor issue within the flight 1420 starting from the organizational influences on that day, followed by unsafe supervisions, preexisting condition to the crews and also any unsafe acts that happened during the landing of the DC-9
The aircraft were stripped down off all unessential items to lower their weight and modified to increase their range. To increase its range by 500 miles, a 225-gallon auxiliary fuel tank were added in the bomb bays, a 60-gallon tank was added to replace the bottom turret, and 10 five-gallon fuel cans were to be used in flight (Cohen). The plan was to launch the bombers 500 miles off the east coast of japan and after the attack head another 1,200 miles to selected Chinese bases. A Russian base in Valdivostok was only 600 miles from Tokyo, but was not selected because of the reluctance of Russian to be drawn into the
When the United States entered World War II in 1941, Eisenhower was appointed to the army’s War Plans Division, where he helped create a strategy for an Allied invasion of Europe (Peterson). On December 24,1943 he was named the Supreme Commander of the Allied Expeditionary Force, which invaded Normandy, France in the largest amphibious assault in history, better known as D-Day (“Dwight D. Eisenhower”). Eisenhower was then made a five-star general before war ended in May 1945 (“Dwight D. Eisenhower”). In 1948 Eisenhower left active duty in the army, and accepted a position as President of Columbia University in New York City (Peterson). According to Peterson, in 1948 he published his book, Crusade in Europe, which was successful.
Chuck Yeager’s later years after all his legacy and achievements involve many commercial endorsements and he is even the main character in a book called the right stuff written by tom wolf’s. Interesting facts in the book about Chuck, Chuck flew more than 200 different types of military aircrafts. He trained many of Germini, Mercury and Apollo astronauts at the air force aerospace research school. During World War II, Yeager shot down more than a dozen German planes. He has shoot down 2 times more planes than any other pilot these exact dates are October 12 and November 27,
What is the Space Race? The Space Race, a competition which grew out of the cold war with both sides wishing to exploit propaganda and military benefits of making the first forays beyond the Earth’s surface and atmosphere It lasted from 1955 to 1972. The USSR won the early victories of this race. It put Sputnik 1 in space on October 4, 1957, along with the first man in space (Yuri A. Gagarin) on April 12, 1961. After that, President John F. Kennedy announced in May 1961 that within a decade, an American would land on a moon and came safely home.
The strategic bombing’s significance during the Second World War had a greater impact on Germany towards the end of the war as oppose to the start of the war since the Allies had technologically advanced. This enabled the Allies to inflict greater damage on Germany due to higher accuracy and increase in production of bombs. At the start of WW2, September 1939, it was clear that the Allies bombing campaign wasn’t prepared well. Bomber Command only had 488 light-bombers and only a few bombs bigger than 250 pounds. As a result, the bombs were too small to even make minimal damage on the Germans and the Allies had experienced rising losses.
There have been 250,000 miles of test flights which pushed the aircraft to its limits in different categories. Only when all tests were successfully completed was the aircraft received official certification. The aircraft is the first aviation aircraft in America since the end of the Second World War. The Boeing 337 Stratocruiser is a civilian version of the plane Boeing 29 Superfortress. The aircraft was known to be successful in the war as it helped with the surrender of the Japanese army by dropping the atomic bombs on Hiroshima and Nagasaki several years ago.
Recent technological changes are making war less brutal. For example, when in past to attack the target would have required an invasion with thousands of heavily armed troops, dislocating huge numbers of civilians and destroying valuable property along the way then nowadays drones, driven by distance, will accomplice the attack much easier and less collateral damages (Goldstein, pp 4). And improvements in battlefield medicine have made combat less lethal for participants. In the U.S. Army, the chances of dying from a combat injury fell from 30 percent in World War II to 10 percent in Iraq and Afghanistan (Goldstein, pp 4). In short the changes in warfare has made world more civilised but even civilised people will have conflicts what to
CHAPTER 3 HISTORY OF GOSSAMER TECHNOLOGY 3.1 GOSSAMER STRUCTURES On August 12, 1960, NASA successfully launched Echo I, the first communication satellite, into space. Echo I, a 100-ft diameter ball of aluminumized Mylar®, was the pioneer of inflatable space satellite technology. However, because of overestimated uncertainties in macro-meteoroid flux, inflatable satellite technology nearly vanished after the satellite launches of the 1960s. Instead, NASA concentrated on using aluminum truss and beam elements in its satellite design. The US Department of Defense and NASA started investigating the design and development of inflatable structures.
