A BWB aircraft is a configuration where the wing and fuselage are integrated which essentially

Boeing’s CDA (Concept Demonstration Aircraft) completely broke the mold with their design, which was very different to say the least. Their X-32 aircraft’s skin was composed of a material known as a “thermoplastic matrix”, which was a composite material embedded in an epoxy resin. When heated, this material undergoes a chemical reaction, thus forming a “highly rigid component” (Sweetman 64). This composite material would give the designers the ability to re-heat and re-shape the wing without having to start over from the beginning. Boeing insisted on using this kind of material because it provided them a way to cut cost. This kind of philosophy, accompanied with their lack of experience in building military aircraft, cost them in the end. After months of demonstrations between both CDA‘s, it was Lockheed Martin’s X-35 that was chosen due to their lift-fan design. The advantage of the lift-fan design, when compared to Boeing’s vectored thrust approach, was that it provided more excess power (F-35 Lightning II). With the 126-month, $13 billion contract in hand, the clock was now running for Lockheed Martin to begin production on the aircraft (Sweetman 95).

Have you ever wondered about the aircraft from World War Two? Or how aircrafts operated, or what materials they used to operate and win in dogfights? The WWII era was one of the first time that airplanes were used to fight in wars on such a large scale and with such a large impact. Aircraft was extremely beneficial in this war. Airplanes were a huge advantage in WWII because of all the ammunition they carried, and they used a lot of resources to help fight during WWII for their country.

One of the technologies invented in world war II was the jet engine. when was the jet engine invented. The jet engine was invented in 1941 by a scientist called Frank Wittyl. Event tho it was new innovative technology it spent most of its time in the war on the ground because of massive fuel consumption

With the invention of the machine gun the fighter plane was created and the first flying “aces” arose. This was important because when both sides were entrenched it became the job of the planes to create an opening. In addition to fighter planes the creation of bombers played a vital role in the war and in subsequent wars. Planes were now able to just drop a bomb on the enemy, causing a large amount of damage. The advancements in aircraft made during wartime paved the way for future generations to create advanced airplanes with useful additions like precise maneuvering equipment and missiles. In addition, post-war advancements include the invention of the tri-motor in 1926, the first single engine plane in 1927, and the first transatlantic passenger plane also in 1927. WWI had a huge effect on the development of plane technology because without it people may have never realized the potential for air warcraft except for the few pilots with the vision of dropping bombs on the

One of the pieces of technology the germans had was the Horten Ho 229 bomber.

As war from the ground or the seas was not enough, war finally expanded to the air in the 20th century. These airplanes were finally introduced to warfare in the year 1911. Airplanes were first used for recon until finally weapons were added to them. Different countries competed to build the best most advanced airplanes. As the time for war came countries such as England and Germany designed fighter planes and bombers too. A couple of the airplanes that Germany managed to crank out for World War II were the ME-109 and the Stuka Bomb Diver. Meanwhile the British had the Spitfire Diver which was used by the Royal Air Force. These airplanes managed to cause major damage during war.

This bomber was “Designed for US requirement, a 4 engine bomber capable for long distance travel” (Writer). One the first flight of B-17 bomber, it started a non-stop flight from Seattle to Wright Field in nine hours. After 40 flight-hours “The prototype crashed, because the elevator gust-lock was still engaged” (Dwyer). The B-17 broke long-range records during its time, there are more This made it a good bomber so they can send it across the atlantic ocean. The flying fortress has four engines, that does 1,2000 horsepower each. The top speed is 282 knots (325 Mph), and can carry about 11,5000 lb. Near the end of the war when Germany was weaken by B-17s. The Allies sent these B-17 bombers in to bomb out the factories. Germany started to not produce that many units, and researching has decreased because of it. Then this handed allies a chance to bring Hitler

Towards the end of the War the airplane becomes a practical device of war being able to carry weapons. Anthony Fokker and Louis Bleriot create the most successful of early modern biplanes known as the D-VII and D-VIII. Biplanes are eventually taken over by the monoplane, or one wing. This new design allowed for faster flight and better visibility for the pilot. Air-cooled engines lead the way for commercial aircraft, and Boeing introduces the first modern airliner the 247. Airplanes are effected the greatest by supply and demand of war. New styles of war begun to emerge so did new and improved types of aircraft. The population of the U.S. also begun to grow which leads to the modern most sophisticated commercial airliner the 777. Most aircraft improvements are found in the military and intelligence field. The most high tech aircraft known today for such things as spying are the SR-71 Blackbird, and the U-2 Spy plane. The most complicated and best aircraft performance is still held by the space shuttle and probably always will be. The last 200 years have seen incredible changes in aircraft from the man with wings to heavier than air flying machines that can travel at supersonic speeds.

The Boeing B-17 was made from 1941 to 1942. The last model was the B-17E which was always being tweaked to meet the needs and improvements pointed out by the brave men that flew them (B-17E, 1). The designer of the bomber was Edward Curtis Wells. It was designed in Seattle, Washington, at Boeing's national headquarters. It also was

The power-weight ratio provided by this unique design allowed their aircraft, the Horten 229 to meet the standards of the jet bomber program despite the limitations of propulsion technology. Furthermore, the aircraft was constructed not out of aluminum, but of wood, thus reducing weight and improving maneuverability. In initial handling tests, the 229 easily outmaneuvered and outperformed the Schwalbe, proving its capability as both a bomber and a dogfighter. With this in mind, the Horten brothers prepared to develop a fighter model which carried twin high-caliber 30mm Mk103 cannons, giving the aircraft the capability to harass light tanks and armored vehicles, in addition to dogfighting enemy interceptors and destroying heavy bombers. The strategic bomber conversion of the aircraft would have carried 1000 kg of ordnance, in the form of two 500 kg bombs. Although the payload of the aircraft may seem underwhelming compared to Allied bombers (the B-17 and Pe-8 could carry up to 2,700 kg and 5,000 kg, respectively) the wooden construction of the 229 would have drastically reduced production costs, allowing large quantities of aircraft to make up for the deficiencies in the payload of individual

The emergent need for a stealth bomber did not come to fruition until the Yom Kipper War in October 1973. Israeli aircraft were detected by Soviet Union radars and shot down at an high rates by Soviet surface-to-air and air-to-air missiles.[1,28] Many of these fighter jets were similar to those that the United States were using which alarmed the air force. The following year in 1974 the Defense Advanced Research Projects Agency (DARPA) funded research into the needed radar cross section that aircraft would need in order to survive the Soviet Union radar threat. [1,28] Lockheed, Northrop and McDonnell Douglas were interested in this research and pursued the DARPA opportunity.[1,28] DARPA began an additional study the Experimental Survivability Testbed (XST) in 1975 where the goal was to mount aircraft conceptual models on poles at White Sands Missile Range in New Mexico to conduct testing on low radar cross-section (RCS) conceptual designs.[1,28-29] These conceptual designs would help Northrop, Lockheed and Defense Department engineers better understand RCS reduction.

The common explanation given to those curious about how an airplane wing produces lift uses the Bernoulli Principle. This is the concept that because of the airfoil shape of a wing, the air traveling over the top of the wing must travel faster than the air going under the

The Lockheed SR-71 Blackbird is an advanced, long-range, mach 3 + strategic reconnaissance aircraft. It was developed for covert missions, and was created by Lockheed Skunk Works. Clarence Kelly Johnson was responsible for many of the design concepts. During the recon missions the SR-71 performed in, it had operated at high speeds and altitudes to allow it to outrace threats. The standard evasive action was simply to outrun and out accelerate any incoming missile.

New Large Aircraft (NLA) or New Generation Large Aircraft (NGLA) are the future of long distance air travel. With current air craft size reaching unknown proportions to humankind, airports that are interested in attracting future business as well as the revenue the large amount of passengers per flight may generate, will have to adapt their installations to the demanding needs of these supersized vehicles. The following paper will focus on the new Airbus A380 and the requirements that airports inviting this magnificent work of engineering to use their installations will need to meet.
