A Brief Note On Unmanned Aerial Vehicles ( Uavs )

The graph shown above compares the different classes of lithium ion batteries that are available today in terms of their specific capacities. The Nickel Cobalt Aluminium combination is by far the most productive lithium ion battery till date. The Lithium Cobalt Oxide battery and the Nickel Manganese Cobalt battery also have a decent amount of energy capacity. The graph also seems to reveal that research on batteries have come a long way from the conventional lead acid batteries.

Kirsch’s main argument in the article is that there are no better storage batteries for the electric vehicle despite smaller technological changes or improvements that have relatively enhanced the capability of these vehicles. The expectations for better storage batteries were not realized though the electric vehicle was

Lithium-ion batteries are becoming more common in portable electronic devices due to their high-energy density, lack of memory effect, and high charge and discharge rate capabilities. Research and development work is ongoing to improve safety and increase capacity, charge/discharge rate, and lifetime. Demand for electric vehicle batteries is currently small, but it is expected to grow very quickly. China, Japan, South Korea, France, and the United States are the major lithium-ion battery manufacturers for hybrid and electric vehicle applications.

Lithium is a mood-stabilizing drug that has been used effectively in the treatment of bipolar affective disorder for many years, and increasing evidence suggests its effectiveness in reducing the risk of suicide ( Sugawara, N.,Yasul-Furukori, N., Ishil, N., Iwata, N.,& Terao, T.2013). There are different ways lithium can be useful to everybody in a different ways. Lithium carbonate is a type of medication used to treat manic depression and bipolar. Another uses of lithium that is very important is in batteries for clinical equipment such as heart pacemaker, blood pressure machines, and respiratory BPAP machine. Rechargeable batteries for electric vehicles, digital cameras, mobile

Traditionally conventional aircraft uses the secondary power system of electric, pneumatic, hydraulic and mechanical power transfer system. Increasing demand of more advance electrical system in aircraft industries has refined the electronic power, fault-control actuator systems into a new level. To reinforce the technological progress of an aircraft electrical system, the concept of More Electric Aircraft (MEA) has been introduced in the electrical system of the aircraft by “replacing non electrical power in the aircraft with electricity.” (Corcau. J.I., Dinca. L., 2012)

Besides, the performances been shown by Tesla’s batteries are unmatched compared to other automakers. While other automakers discussed the long-term likelihood of the lithium-ion

In 2006, Sony recalled 4.1 million notebook batteries due to six cases of spontaneous combustion (Krazit, 2006; Hollister, 2015). In 2013, lithium ion batteries caused airplanes to be redirected due to safety precautions (Musil, 2013). Lithium batteries have evolved since these incidents to better assist technology. The mishandling, poor design, and cheap manufacturing of the battery caused these accidents. Recently, in 2015, lithium batteries went under fire due to potentially being the cause of hoverboard fires. However, the causes of the fires are unknown and are currently being investigated. The initial blame of the problem is on the batteries contained in this product and not the cheap production or lack of standards for the product. The combustion of the lithium ion batteries in hoverboards is a magnified

The relatively higher cost of EVs has held the market back from fully competing with conventional vehicles. The cost of batteries is the primary factor behind PEVs’ high label price. Batteries make up roughly one-third of the cost of today’s electric vehicles. Further more, electric vehicles require batteries with both high endurance and power, and there is often a tradeoff between these capacities. The term battery pack has been used in to refer to battery of electric vehicles. According to Wikipedia, “Components of battery packs include the individual batteries or cells, and the interconnects which provide electrical conductivity between them”. Battery pack technology has been one of the main interests of automobile companies since configuration

Technology has been advancing since the turn of the century at an unparalleled pace with the constant announcement of new gadgets and innovations. Of the thousands of new technological advancements made in the past decade, the introduction of the electric car has been the most widely discussed topic. Electric cars are one hundred percent emission free and can replace the fire spitting, bone chilling sounds of a thunderous gasoline engine with the eloquent silence of luxury and speed. However, as with all things technological, electric vehicles have their problems. Electric cars have several benefits and could possibly replace gas cars in the future, but they are not refined enough to take over the world today because of a few technicalities

Propulsion: Gasoline or Electric? The two most common methods of powering unmanned aerial vehicles is via gasoline engine or electric motor. Gasoline engines provide more power (and thus more payload capability) and might have a longer endurance; however, the vehicles are generally bigger, require frequent maintenance, and a source of petroleum. Electric motor systems, by comparison, are quiet, but have more limited power and endurance.

Electric powered vehicles are approximately 90 percent more efficient than those using fossil fuels, which is the primary reason that it is nearly always cheaper to drive a mile using electricity as a fuel rather than gasoline . One challenge concerning electric powered vehicles is that the batteries are both heavy and expensive. As technology and adaptation progress, however, it is anticipated that AA that are fully or partially powered by electricity would be able to travel the same range using batteries that are smaller, and thus, cheaper. As a result of the improved drive cycles and decreased traffic congestion, the use of electric powered AA would further allow for using smaller and lighter batteries. This would reduce the overall cost for consumers, and hasten the adoption of conventionally sized electrified vehicles. Smaller batteries would also reduce life-cycle environmental impacts from producing electric vehicle batteries, as well as reduce their environmental impacts at the end of their useful life. Electric vehicles charged by low-carbon electricity have the potential to dramatically lower the level of GHG emissions, oil use, and conventional air pollutants. Moreover, AA can be programmed to drive in a way that is fuel efficient so that by programming travel speeds, accelerations, and even mapping out optimal travel routes AA can be programmed to reduce power consumption.

On Saturdays in the fall, more than 50,000 people pack themselves into Bill Snyder Family Stadium to watch the Kansas State University Wildcats play football. More fans occupy the parking lot surrounding the stadium, and even more can be found in satellite parking lots farther from the stadium (K-State Athletics).

More efficient and durable batteries are needed to satisfy the requirements of new technology developments.

Years before the first manned airplane flight on December 17, 1903, technology that is used in UAVs today, was being used for combat and surveillance. During World War I, the first UAVs took flight in the United States. Although the success of UAVs in test flights was irregular and different, the military recognized their potential. For more than ten years after World War I, the development of unmanned air vehicles in the U.S. started. During World War II, Germany 's innovative V-1 demonstrated a great and scary threat as well as the power that a UAV could pose in combat. America 's attempts to eradicate the V-1 laid the beginning for UAV programs in the U.S.

Nowadays, new technology is rapidly shaping the way how construction projects are delivered. The application of unmanned aerial vehicles (UAVs) is one of these examples. Unlike conventional aerial measurement by aircraft, it doesn’t require expensive aeronautical facility and trivial procedure. Comparing to other surveying approaches like using the GPS navigation, the UAV systems can outperform in many large-scale projects by saving cost and time. There many explorations to potential applications of UAVs - budget and schedule control, construction innovation, and safety practices. However, in the United States, the Federal Aviation Administration (FAA) regulations and many state regulations often prevent or limit the wide use of UAVs. In
