The invasion of Normandy, also known as Operation Overlord or D-Day, was perhaps one of the most important battles in the human history. The invasion took place on June 4, 1944, at the Coast of Normandy in France. Troops from over twelve countries, including Canada, the United Kingdom, and the United States of America participated in the fight against Germany. Although the battles were enduring and hard-fought, the Allies achieved the final victory; the Allies were finally able to set their feet on the European soil again. The Allied invasion of Normandy was a major turning point of the war that led to the ultimate liberation of Europe from the Nazi forces.

D-Day happened on June 6 1944, We invaded normandy beach, There were over 425 thousand allies and germans killed or injured or just ran away.

On June 6, 1944, the Allies invaded Normandy to liberate Western Europe from the Nazis that had taken it over in 1942 (Tucker). There were as many as ten thousand Allied troops involved in the operation (Tucker). The Germans expected an invasion, as a result, they protected places where the invasion would take place (Tucker). Hitler built defenses that included forts, tanks, guns, and barricades to keep the Allies from invading France (Tucker). This bloodbath war caused many men to be fatally injured, and many men lost their lives (Tucker). The D-day invasion from the Allies was a significant turning point of WWII because it caused Hitler’s defenses to fall and crumble.

D-day is and was one of the greatest allied invasions in the history of the world.Troops from all over took place in this invasion.In fact more than 160,000 allied troops took place in the invasion.It started all when Nazi Germany invaded France.They were on a path of destruction. D-DAY actually started on June 5, 1944. People just think it took place on June 6, 1944. This is just not as known. 5 beaches were invaded by the allies.The beaches were sword,Juno,gold,Omaha,and Utah.Canada,America,and Britain would divide the beaches into in the assault.America would take 2,Britain would take 2,and Canada would take 1.This was the battle plan.There were 9,000 allied casualties.It was worth it though.The beaches had finally been taken in the end.The

June 6, 1944 also known as(AKA) D-Day is within the era of World War 2. The world war 2 era is the time of the second world war, were Adolf Hitler and his German Nazis soldiers were slowly becoming more insane and wanted to try to rule and cleanse the for themselves, instead of helping someone else rule the world.

“D-Day”, is considered one of the most significant battles of World War ll. D-Day is also known as the “Battle of Normandy”, or, “Operation Overlord”. The Battle of Normandy began in June 1944, and ended around August 1944. By the end of the war around August 1944, all of France had been cleared of Nazi forces. D-Day is considered a huge factor with the end of World War II and the Nazi Party due them having to push out of France and back into their initial land of Germany. Later on as the Nazi Party was pushed back into Germany, more allied forces collaborated to officially wipe out the Nazi Party in Germany. D-Day was initialized as it was approved by General Dwight D. Eisenhower. After the approval of the general, troops landed on the French coasts to neutralize the Nazi Party and to recover the land.

Operation Overlord, one of the largest marine attacks in history, was what led to the liberation of Nazi Germany. More commonly known as D-day, Operation Overlord was the codename for the Battle of Normandy(1). The battle took place on June 6, 1944 and was the 1,738th day of World War II(1,4). Normandy was split into 5 beaches, America would take Utah and Omaha beach and the British and Canadians would take Juno, Gold, and Sword. 156,000 American, British, and Canadian soldiers were part of the invasion force. The plan for D-day required elaborate planning and deception. What happened during D-Day helped lead to the allies liberated France in August and defeating the Germans the next spring(1).

Although the term D-Day is used routinely as military lingo for the day an operation or event will take place, for many it is also synonymous with June 6, 1944, the day the Allied powers crossed the English Channel and landed on the beaches of Normandy, France, beginning the liberation of Western Europe from Nazi control during World War II. Within three months, the northern part of France would be freed and the invasion force would be preparing to enter Germany, where they would meet up with Soviet forces moving in from the

June 6, 1944 would be known as D-Day. Germans were mounted behind heavy guns, though many were asleep with their commanders gone. They weren’t expecting an invasion due to bad weather conditions, just like Rommel. Some areas seemed impossible to get hold of, such as Omaha Beach where U.S soldiers fought for hours just to

“Over 425,000 Allied and German troops were killed, wounded or went missing during the Battle of Normandy.” This is the statistic that made me want to learn more about the historical event called D-Day. D-Day required detailed planning, it was an international effort, andand as you will read this paper, it was possible because of allied efforts elsewhere.

Even though the design of the modern helicopter was not perfected until the late 1930s, it is arguably one of the earliest ideas for achieving flight, predating the concept of the glider by perhaps as much as two thousand years. Inspired by the flight of birds, even ancient humans dreampt of soaring at high speeds, stopping on a dime, and hovering in place, much like a

Igor Sikorsky widened the field of aviation throughout his life with inventions that caught the interest of the world. In the early 1920’s, after successfully building a four-engine biplane, Sikorsky began his work on amphibian aircraft. The aircraft proved to be versatile with its ability to take off and land on an airstrip or in the water. Sikorsky increased the size and maximum range of his designs until producing the S-42 Flying Clipper. His line of amphibian planes became the precursor to commercial transoceanic flight. He played an important role in both the introduction of amphibian aircraft and its transition into commercial aviation. Sikorsky also contributed heavily to the development of the helicopter and research of rotary flight design. His design concept that had one main lifting rotor in combination with a smaller rotor to counteract torque is still used in modern helicopters. The helicopters maneuverability and ability to lift off vertically allowed it to fly into and out of terrain not fit for normal aircraft. He designed the R-4 which became widely produced and utilized by the military mainly for delivery of supplies and search and rescue. The company he began in New York, now called Sikorsky Aircraft, produced the S-70 Black Hawk helicopter in response to the Army’s need for a durable transport helicopter in 1972. Sikorsky Aircraft manufactured over 900 aircraft for the Army by the end of 1989 and a family of helicopters spawned from variations of the

The Boeing Vertol BV-347 Helicopter was a prototype that received a fly by wire system modification and stronger Lycoming T55-L-11 engines. These combinations provided a max speed exceeding 180 knots. These improvements combined with this new technology helped achieve better flying characteristics that helped develop some of the finest aircraft we now use in our fleet.

The microwave, also known as a microwave oven, was seemingly a breakthrough in technology in the early 1940’s that allowed whole meals to be prepared in minutes. The idea of the microwave was created by a man named Percy Spencer. Mr. Spencer developed the plans based on radar technology breakthroughs from World War II. The microwave was originally named the Radarange and first hit store fronts in 1946. The Radarange did not sell to well as they were rather large and bulky for regular home use. In 1955 a company known as Tappan created a new version but even that version was too big and expensive. In 1967 the Amana Corporation introduced the first countertop microwave oven and since the microwave has become the most used kitchen appliance in the world.

Presented at the 2014 International Conference on Unmanned Aircraft Systems (ICAUS), this paper identifies the need for a low cost approach that is effective in building commercial based small unmanned VTOLs. The researchers’ discuss and analyze the TURAC, which is an easily reproduced tilt rotor VTOL. The paper details the design, manufacturing process, and platform architecture of the TURAC.
