History Of Military Aircraft Essays - Stealth Aircraft, Monoplanes

History of Military Aircraft Military aircraft has become more sophisticated in variety, effectiveness in war situations, and special maneuvering techniques in recent years. With the advance of stealth technology, many new and very effective aircraft have been developed. The F-117A was used during Operation Dessert Storm and every plane came back without a scratch. The very expensive B-2 stealth bomber has never been used in actual war, but during testing it was a success. The Advanced Tactical Fighter program was started to make an aircraft that could supercruise, the ability to cruise at supersonic speeds, and didn't cost very much. The YF-22 and YF-23 were the first planes to accomplish this. With all the planes we know of, there are also top secret programs probably going on right now. A new fighter that has never been heard of before has been spotted. As John Welch, the assistant secretary of Air Force said, "Stealth gives us back that fundamental element of war called surprise" (Goodall 9). After it was found that aircraft could be very useful in war, it was used for large scale reconnaissance. Then people started to add bombs to aircraft and then airplanes started to become an essence of war. After World War 2, new bombers were developed with fast speed, and could travel far distances. They could also carry nuclear bombs and missiles. The use of the bomber aircraft then led to the fighter, which was equipped with guns and missiles. Helicopters were also found to be good strike aircraft. They were armed with cannons, machine guns, rockets, torpedoes, and a variety of missiles. Vertical takeoff made the helicopter an advantage. The first flight of the F-117A was in June of 1981 in Groom Lake test facility. The total cost for the development of the F-117A was just under two billion dollars, but it only cost $43 million to make each plane. It became operational in October of 1983 and was the first operational stealth aircraft ever built. The F-117A is a night attack plane powered by two, nonafterburning General Electric engines. F-117As were designed for first-strike capabilities and to be able to fly into any countries airspace undetected. The primary task of the F-117A is to break through enemy airspace, destroy high value targets, and return back unharmed. They were considered to first be used in several different tasks, but weren't used until Operation Dessert Storm where they did an excellent job. As Donald Rice, Secretary of the Air Force, said, "Everyone now agrees the F-117 was a real bargain" (9). During Operation Dessert Storm the F-117As were found out to be very successful. The war began on January 16, 1991 when the F-117A fighters entered the Iraqi airspace on their way to downtown Baghdad. There were 43 of them over the skies of Iraq and not one was lost even though they went against one of the most modern air-defense systems in the world. Operation Dessert Storm was the largest aerial bombing attack in war history. It was also the first time a stealth aircraft was used as a main weapon. On the first day of Dessert Storm the Lockheed F-117As dropped sixty-two 2,000 pound bombs on Baghdad destroying the most critical targets of the Iraqi military, including the headquarters of the Iraqi air force. "We've seen that not only does stealth work, but that it puts fewer assets at risk and saves lives" (9), as Donald Rice said. The pilots of those F-117As flew through the hardest anti-aircraft missiles any pilot has ever flown through. When you think of stealth, most people probably think of B-2 stealth bomber, but most people don't realize that it hasn't even been used in a real war situation yet. In November of 1987 the Pentagon ordered the first four B-2s to be built for $2 billion. Each B-2 cost $437.4 million to build. After the military liked the bomber, they originally ordered 133 of them, then they cut back to 75 because of the deficit-reduction bill. Then, in 1992, the House of Representatives voted to buy only twenty, and later only 15 saying that 10 would be enough. With four General Electric engines with 19,000 pounds of thrust each, the B-2s were made to carry a lot of weight.

Brief History of Math essays

Brief History of Math essays In my years studying math Ive realized that math is essential for life. Having this said, It is quite obvious that math could easily be as old as humanity itself. Prehistoric men has interests in geometric figures in their pottery. As we first learn in out toddler years, to count with our fingers, it is almost certain that barbarians (as some call prehistoric men) used this system. And according to the Microsoft Encarta encyclopedia there is proof that they based their mathematics on a system of 5, 10 etc. The earliest records of advanced mathematics come from the cities of Babylonia and Ancient Egypt in 3,000 B.C. The Greeks really advanced humanity in Mathematics. Mathematics like Pythagoras, Hippocrates and Thales who advanced math in an astonishing level. The level of comprehension that the Greeks had was astonishing. They were the first to fully understand the pyramid. The invention of the Pythagorean theorem was brilliant. Great ads to geometry were made. They also began trigonometry. Islamic Mathematics date back to ninth century A.D, Indian people were already performing algebra problems. Muslims also expanded the theory of numbers, and explained many ways of solving equations. They were also responsible for the expansion of Math in the West (to Europe). The Renaissance Mathematics was a period of many great discoveries. For one, Infinity had begun to be used in the end of the 15th century and beginning of the 16th century (A.D of coarse). There was also discoveries of algebraic solutions to cubic and quadratic equations. The Renaissance also gave way to the beginning of algebraic symbolism: a + b = c. Also great developments in the next century by Sir Isaac Newton from England. In the 17th century many new great steps for math were made. For starters, the probability theory was made, and later proven. Sir Isaac Newton, as well as some other mathematicians made the creation of calculus., and dif...
