Mechanical And Structural Factors Of An Aircraft

This report is prepared to assist the aircraft solutions (AS), a well-known company for equipment and component fabrication in Southern California, in identifying the most important security vulnerabilities. This report also discusses possible threats, the likelihood of the threats occurring

Since the beginning of aviation, aircraft have been used for other intentions besides carrying passengers and cargo. They have been used as weapons of war dating all the way back to the first world war, and the use of aircraft has enlightened the advancement of the aviation. “Throughout the history of aviation, the greatest progress in flight has been made during time when either war or the threat of war was present” (Millspaugh, et al., 2008, p. 33). However, the war we face today has been triggered by the deliberate use of aircraft to cause death, destruction, and mayhem.

One contributing factor was metal fatigue, this occurs when “metal parts that undergo many repeated strains eventually fail at a loading far below their original ultimate strength”, Garrison (2005) (p. 1). Manufacturers at the time primarily used aluminum and steel, because of their overall strength and how readily they were available. What engineers did not consider was the abuse the airframes would take over time. This factor went overlooked, resulting in numerous crashes with fatalities.

AIAA has earned an international reputation as the preeminent publisher of cutting-edge aerospace books and journals, and the leading source of aerospace industry archives, dating back to the early 1900s. Over the past eight decades, AIAA and its predecessor organizations have published over 300 books and almost 200,000 technical articles. AIAA’s current publications include seven technical journals, a magazine, three book series, national and international standards documents, a growing number of e-books and other electronic products, and a full-service, interactive Web site. For the most authoritative technical publications, look to

To fly was a tremendous triumph for mankind, who was previously sentenced to a life only walking the earth. Since the inception of the airplane, there has been aircraft maintenance. However, this industry has changed dramatically throughout the years and now involves highly innovative technologies and incredibly skilled technicians in order to best maintain the incredibly complex aircraft that fly in today's skies. Maintaining an aircraft is a harmonious blend between simple and intensely complicated procedures. Many procedures even still used to day are relatively simple and have existed for generations, including the basic engine work, refueling and other servicing procedures, and other after-market manufacturing that might take place on particular planes. This is now combined with impressive and innovative technologies that are highly regulated under a wide number of international agencies.

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

There is a world of jobs and careers out in the world. I don't want to be a doctor or nurse or vet or anything like that. All i want to be is a Mechanic. Not a car or truck mechanic but an airplane mechanic. It's my dream to go tho airfields and work on airplanes. As i'm working on airplanes I would love to have my pilots license as well. My career is going to consist of awesome airplane mechanics.

“The human being is set apart from all other animals by an intelligent, reasoning mind. Another quality that humans seem to possess is an inherent drive to utilize that mind to achieve to recognize challenges and to attempt conquer them” (Smith, 1992, p. 1). One of my favorite person that I used to read about in high school was Benjamin Franklin; one of the founding Father of the United States of America and the master mind behind the invention of electricity. As stated in the words of Smith, the curiosity of Franklin lead him to discover how electricity works. This same driven factor of human mind was what led the Wrights Brother to invent and fly the first power aircraft. The four forces that are acting on an aircraft in flight are: Lift, Weight, Thrust and Drag.

As humans, one major phenomenon that we have been able to learn about is the mastery of flight. Without the discovery of flight, airplanes would be a pipe dream! There are about 4 major forces that play into affecting how flight works. In this research paper we will discuss all of the concepts that allow this complex process to take place. The first force that we will discuss is one known as weight.

In the world of commercial flights, we can all nod in agreement that the Boeing series must be one of the best there is of its kind. We have all seen Boeing planes circle the skies, and some of us are even lucky to have experienced riding them first-hand. The sheer size of a Boeing aircraft is just magnificent and its reliability for a safe travel is surely second to none.

The theories behind how an aircraft flies are still, too this day, highly debated as the aviation community is unable settle on one sole idea. The best way too try and describe the principles of flight is by incorporating a few of the theories together and then applying them to the shape of modern aviation aerofoils (the cross-section of an aircraft wing). To develop some basic understanding of how an aircraft flies, we should look at the four forces which act upon an aircraft in steady flight and they are shown in Figure 1.

Since the beginning of recorded history, humans have always had a fascination with flight. Now that we live in a world where boarding an airplane and flying across the country – or even the world - is simply a part of everyday life, the wonder of flight has diminished for many. Despite this, physics students from all around continue to delight in the many physical forces that play a part in keeping these huge objects (like jumbo jets) from falling out of the sky!

Aircraft maintenance is very important for aviation industry and Aircraft are required to be maintained after a period of calendar time or flight hours or flight cycles. Aircraft maintenance is the inspection, repair, overhaul, modification of aircraft or aircraft component. Aircraft maintenance generally includes such tasks those tasks required to restore or maintain an aircraft’s systems, components, and structures with Airworthiness Directives or Service Bulletins and this is highly regulated, in order to ensure safe and correct functioning during flight. Aircraft maintenance requirements vary for different size and types of aircraft, experience which most aircraft need various type of preventive maintenance every 25 hours or less of flying time, and minor maintenance at least every 100 hours. Maintenance is influenced by some kind of operation, climatic conditions, storage facilities, age, and construction of the airplane. The profession of Aircraft maintenance requires extreme knowledge and adept expertise in performing the ingrained tasks. The aircraft maintenance engineer who is on duty he has a great responsibility to work professionally to ensure the safety of aircraft, customers and maintain the reputation of the team or company. The aircraft maintenance engineer normally works in an aircraft hangar and line maintenance and The aircraft maintenance engineer will undertake a number of processes including They may specialize by working on particular aeronautical

Residual stresses [1, 2] are of great importance in any manufacturing industry as it plays a major role in determining the structural integrity of the component being engineered. Residual stresses highly influence the strength, stability, resistance, fatigue life and performance of the component manufactured. These properties being affected leads to failure and repair of the component or the entire structure. Hence it is essential to measure the residual stresses present in a component and to relax these stresses to improve the performance and reliability of the component. A residual stress analysis in design phase is compulsory in order to estimate the reliability of the component [1].

It is a widely accepted notion that aged aircraft are a risk, but to consider them to be an unacceptable risk is a multifaceted question, since the majority of the party that are involved with it disagree[3]. With that said, it is observed that the problem with ageing aircraft starts as early as defining it. For example, according to the Federal aviation administration (FAA), 'ageing ' starts
