Aerodynamics

health effects is substantial with the most deaths attributed to ischemic heart disease (IHD), chronic obstructive pulmonary disease (COPD), and stroke (Figure 3) (WHO, 2014). These health effects are a result of fine particles (less than 2.5 μm in aerodynamic diameter) being deposited deep in the lungs. These smaller particles deposit deep in the lungs because they stay entrained in the airflow and then settle in the alveolar region of the lungs (Hinds,…

Overview. Financially, Alaska Airlines is a strong performer in the modern airline marketplace, having come a long way from its storied Alaskan bush plane roots. Today, Alaska Airlines is the 7th largest US air carrier and is ranked 5th for overall performance among the top 12 carriers for 2014(Alaska airlines: Company facts.; Bowen & Headley, 2015). Notably, in 2015 Alaska Airlines carried 21 million passengers on 173 thousand flights resulting in 27.768 billion Revenue Passenger Miles (RPM)…

THE ROLE OF AIRBORNE WIND TURBINES IN ENVIRONMENTAL PRESERVATION In partnership with increasing concern over the condition of the global environment, engineering has taken on a more constructive perspective on using modern technology to manipulate many of the renewable resources provided by nature. Wind, for example, has emerged in conjunction with rapid advances in turbine technology as a more reliable electrical energy tap for industry. Using massive propeller blades and an electrical…

Native American is the bow and arrow. These bows were in turn not used for lengthy distances, but for shorter targets after approaching a close range to fire the arrow; stone heads were accompanied by feathers attatched to greater increase the aerodynamic aspect of the desired target. Through this smaller projection range, a kill was more powerful and accurate than that of a long spear attack. Getting even closer to the enemy would become the knives greatest advantage to the skilled and craft…

Mountain Bikes Vs. Road Bikes Speeding down a trail or speeding down a road on a bike? What makes a mountain bike similar to a road bike or different? Is there any differences, an average person would ask. If taking the frames into consideration that's where the biggest differences come in. Even though they are both bikes, have two wheels and pedals, they are designed for completely different aspects. Mountain bikes are made to ride in the mountains, and road bikes are made to ride on the road…

we didn’t have so long ago. The first cars were not fast or very efficient. The cars were slow going and took an extremely long time to get to place to place compared to the cars we have today. The cars in the past are very primitive and not aerodynamic. The cars we have today are a…

The Volkswagen beetle is one of the most recognized cars from nearly any point in automotive history. The VW beetle is one of the first common man cars, making its way from the early sides of Germany warming up for World War Two, to the 1970s, with hippies fighting their ways to peace and love across the world. And finally the Volkswagen beetle survives today as one of the cheapest cars but yet the oldest produced car in the war today. The Volkswagen Beetle has made an impact in history from…

Along with advancements in technology, changes to the very nature of war is inevitable. Proven throughout history, the side that better adapts usually emerges triumphant. The interwar period between World War I and World War II, produced many technological advancements that greatly altered the way wars were fought, such as the weaponization of airplanes. Unlike World War I, airplanes played a major role in World War II; from destroying military bases to flattening cities, airplanes were the ones…

Chevy vs. Ford Below is a comparison of two similar trucks for a first-time potential purchaser of a brand new standard truck. Chevy and Ford have been manufacturing cars and trucks for over 100 years. Now that the consumer has narrowed the choices down to a standard Ford F150 Super Cab or a Chevy Silverado 1500 Crew Cab, the difference between the two needs to be established. Both trucks appear to be equivalent to the untrained eye. Each of the manufacturers has a solid history and reputation.…

Electrical trains transport systems are the most widely used forms of transport especially in major cities all over the world (Mraz, 2011). They are more efficient and enable transportation of a big number of passengers at once. This research focuses on electric trains that use the 25Kv AC railway electrification system. The current state-of-the-art electric train systems High-speed (HS) train technology is the current state-of-the-art in electric train transport systems. High-speed trains are…
