Use Of Propulsion And The Basic Principle And Theory Of Propulsion

1. In 1930, who first patented a design for a reaction (jet) type motor suitable for aircraft propulsion?

The first flight occurred in 1903 when the Wright brothers famously took their airplane for a final test flight in December. In the years after this historic flight many people start to see the potential for airplanes in war, transportation, and shipping. Other builders disregarded previous doubt about flying and began to replicate the ideas of the Wright brothers in creating planes with three axes. In addition, the approach of WWI prompted military personnel to pursue uses of airplanes as a war machine. The airplane influenced many aspects of American culture after it’s invention including civilian life, war technology, and individual possibility.

Ever since the development of the first few examples of rocket power, it was evident that this was technology that was going to change the face of the world forever. Since missiles and other weaponry were now able to be launched across continents and even oceans, it made the world feel a whole lot smaller. In turn, this was the technology that “had its ultimate foundation in the simple power rocket which originated as a weapon of war” . However, this technology underwent an extreme transformation over time and was eventually the basis of the technology used to put spacecrafts up in space. One of the main rockets that is going to be discussed in this paper is the V2 rocket designed by the Germans during World War II, as much of the technology that put spacecrafts in space came from this rocket. Another aspect that is going to be

In today’s world, the use of airplanes in wars or in everyday life has become a part of how we live as human beings. Removing the air forces of the world is like taking a step back in time when wars were only fought on land or sea. WWI began only eleven short years after the Wright brothers achieved powered flight in 19031 and yet aircrafts were being used for surveillance and eventually combat purposes. It is understood that these aircrafts were primitive, but they laid down the foundation for what we know today as fighter jets. The Fokker Eindecker “revolutionized air combat by successfully employing a synchronized forward -firing machine gun mounted on the engine cowling”2. Because this airplane became the first to successfully use a

The aircraft propeller looks like a simple mechanism to the uneducated individual. To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. This report will touch on the history of the propeller, from early pioneers/experiments, advancement during/after the war, all the way up to current applications of the propeller.

From a little air separation with every fleet, the Navy's air arm developed to three aircraft carriers with allotted fighter, torpedo and bombarding squadrons; patrol squadrons working from seaplane tenders; and scouting aircraft frequently appointed to ships and cruisers. Naval aircraft went to sea with enhanced equipment. Proficient and reliable air-cooled radial engines were developed during this period. Air-cooled radial engines were so productive and successful that the Navy operated them until the jet era. The Navy joined in the air races during the twenties and early thirties. On the other hand, Navy aviator applied their knowledge to new habits in photographic surveys and polar study.

Soon after, men mastered the laws of aerodynamics and started finding various ways in which they could harness the new invention

Aviation technology was advanced to a great extent because of World War One. From the aircraft’s primitive beginnings in 1903, a number of significant advances were made during wartime. The intense hardship of the war tested the effectiveness of airplanes in World War One, and from these advances aircrafts developed further into the machines of today. The Wright brother’s unsophisticated machine was not intended for use as a weapon, but these purposes changed due to the war, and changed the future developments that would occur. The fierce competition produced by countries fighting for domination of the skies caused neither side to gain a permanent advantage in the air; forcing militaries to work even harder on improving their technology.

In this chapter, it was tried to describe a new perspective for the future aviation industry fuel provision. Considering serious constrictions ruled by CAAA, it is of high probability that Avgas, the current conventional aviation fuel, will be forbidden because of air polluting problem it causes and the fact that it contains considerable amounts of lead element which is hazardous. Ethanol, as a green biofuel, has a promising production potential to be introduced as an alternative fuel according to the current aviation market capacity. Advantages and disadvantages of ethanol usage as an aviation alternative was fully described. The necessary airplane engine modification was mentioned to compensate some of ethanol drawbacks along with some case

Three main areas Computational Fluid Dynamics, Alternative engines and advanced materials are considered in research.

Do you ever wonder why things move and stop? Do you ever wonder why things move up and down? The reason behind motion is something called the 4 forces, thrust, lift, drag, and gravity. Thrust is the force which pushes an object forward. Lift is the force which causes an object to fly. Drag is the force which slows an object down while it is moving. And gravity is the force which pulls every object down. The motion of bodies to these 4 forces are described by 3 Laws. They are called Newton's Laws Of Motion. We can use these laws to help understand the physics

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!

Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.

Aircraft fuel efficiency has improved significantly since the beginning of the jet era in the 1960s, and from 1970 to 2000 total energy intensity was reduced by more than 60%. Fuel burn is a key determinant of aviation economics given that fuel costs account for up to 35% of total aviation costs. The aviation industry has therefore focused on fuel efficiency improvement through engine and aircraft innovation which has resulted in a reduction in total energy intensity of more than 60% since 1970. There are a number of evolutionary technologies that could help achieve further fuel efficiency improvements in new aircraft over the next 20 years. Aviation engineers have been working on silent aircraft and using 3D systems in aircraft to make precise aircraft design which will be very useful for cargo purposes and for travellers to reach their destinations. Students of Cambridge university are also been working on silent aircraft which will reduce the aircraft noise and improve the fuel efficiency.

Carry out experimental work using the Open jet facility available in the Aerodynamics laboratory, Department of Aerospace Engineering, Madras Institute of Technology.
