The effects of intake modification on a Ramjet engine A ramjet intake design analysis. Supersonic and hypersonic flights often make use of a ramjet engine during the cruise phase of the flight. The design of the intake affects important variables of the ramjet engine, namely Mach number distribution, formation of shocks and pressure distribution. Analysis of a normal intake design provides lower than optimal pressure to the combustion chamber. A geometric dimension modification on the intake,
The SCRAMJET, simply abbreviated from Supersonic Combustion Ramjet, is the latest evolution of the jet engine family. NASA made the news with each test of the X-43A scramjet craft, so I set about to discover why this type of jet engine should garner so much scientific attention. Turbojet The most basic jet engine is the turbojet. As soon as the air enters the front of the engine, the blades of the compressor, compresses the air before funneling it into the combustion chamber. During the
necessitating a high AOA is the most likely situation to cause a low-speed Mach buffet. The situation that increases, the angle of attack, the speed of the airflow over the wing, and chances of Mach buffet are (FAA, 2008): Higher altitudes—the higher aircraft flies, leaner the air and the greater the angle of attack is necessary for producing the lift needed to preserve the flight level. Heavy weights—the heavy aircraft, lead to greater lift from the wing and larger angle of attack. Supersonic

Introduction The idea of interstellar space travel has been discussed for many years between many scientists and engineers since 1950s (Adelman, 180). It has not only been discussed but also demonstrated in science fiction literature. By getting the knowledge of interstellar travel, people wonder when will we be able to travel between stars and if it is even possible to reach another star other than the sun. However, others wonder “what is the point of spending so much money on something that it
Speech Operating at altitudes of 85 000 feet, cruising at speeds over Mach 3.2, undetectable to enemy radar and unsusceptible to aerial defences. The Lockheed Martin SR-71 Blackbird. Good Evening Mr Hanley and classmates. In the following presentation I will demonstrate why the monumental Lockheed Martin SR-71 Black Bird was possibly the best advancement in aviation history and why the SR-71 is a testament to the evolution of aviation technology. The Lockheed SR-71 Blackbird was the result of
The Structure of an Airplane The idea of flight has fascinated people for centuries, even to this day, which is why I decided to research on airplanes. When I researched the history on planes, I was surprised at the effort and the time people long ago spent trying to make a machine that flies. I also wondered, like many, how an airplane is able to fly and sustain in the air. Wanting to know the answers to these types of questions I had, gave me the determination to really researched this topic
Evolution of the Jet Engine Thought the course of time man has constantly sought to better both himself and mankind through creation and invention. From the first time a caveman rubbed two sticks together and discovered fire to the design and development of the Saturn 5 rocket which propelled by that same fire carried man from the earth to the moon. One can argue over whether on not this invention or that was the greatest. I intend to focus my attention on evolution of just one of those technologies
INTRO during world war one there was several successful technologies used, but there was also several that failed. technology was a key in world war one and without it the soldiers involved in the war would of been unsuccessful in battle. There was not much technology available when world war one took place but the technology they had was extremely important. Technology that made the greatest significance was rifles, barbed wire,machine guns,aircrafts and many more devices yet it did come with unsuccessful
jett engines. JET ENGINE A jet engine is a reaction engine discharging a fast moving jet that generates thrust by jet propulsion in accordance with Newton's law of motion. This broad definition of jet engines includes turbojets, turbofans,rocket, ramjets and pulse jets. In
Outer Space is by far the hardest place for mankind to explore. Instead of having to only find out how to make our ships float better, we have to think about the lack of air and radiation from the sun. That is only a couple of issues that come up when you think of space travel. We have to think about all the technology we would have to improve to make more efficient parts. We also have to consider the health risks that come with being in a zero-g environment. Earth will not sustain us forever, eventually
With all the materials they need that is a minimal cost. Another major requirement for interstellar travel is its fuel. They have to think of new ways to either get fuel, or carry a lot of fuel with them. “Instead of carrying its own fuel, a Bussard Ramjet would scoop up the very thin traces of gas and dust found in interstellar space, known as the Interstellar medium, using a vast funnel shaped electromagnetic field that extends for thousands of miles in front of the spacecraft.” (http://www.livescience
