Fluid Mechanics-II Project Farhan Akram Department of Mechanical Engineering College of Electrical & Mechanical Engineering National University of Sciences & Technology Rawalpindi, Pakistan email@example.com Question - Large commercial airplanes cruise at high altitudes (up to about 40,000 ft) to save fuel. Discuss how flying at high altitudes reduces drag and saves fuel. Also discuss why small planes fly at relatively low altitudes. (Cengel 11-112) Index Terms – Plane, Altitude. SOLUTION The pilot needs to know how high above the earth the plane is traveling, i.e.
The B-24 was very advanced and very powerful at the time. It was manufactured right here in America, and only used by our allies. It was mass produced because of its popularity and importance, and was an all around superstar in helping us win the war. This plane was a one-of-a-kind, and there
I also really like the part when the jet is in its maximum speed allowing it to glide and feel weightless. It’s a flawless combination of strength and beauty that only a pilot can feel.” After this last question, the rest of our interview became less formal and more of a family/personal talk. Therefore, the questions asked after would be irrelevant to write. Our interview went on for about one hour and half or two. It was definitely a memorable experience for many reasons.
Aircraft Catapult Military aircraft are often required to operate from very short runways, such as aircraft carriers, where the runway length is too short to allow the aircraft to take off conventionally under its own thrust. An aircraft can only take-off once it produces a lift force greater than its weight in order to accelerate vertically. From the Lift equation: L=1/2 C_L ρAV^2 Where L is the Lift force, C_L the lift coefficient, ρ the air density,A wing surface area and V the velocity.  The only variables the can easily be changed without reconfiguring the aircraft is velocity and as such in order to decrease the take-of distance, take-off velocity must be reached in a shorter time period and hence the aircraft acceleration during the
2.3 Aerofoil Aerofoil is the cross-sectional of an object that are moved through a fluid such as air, and aerodynamics force created. Aerofoils are employed on aircraft as wings so then it will produce lift or others depending to the blade shape to produce thrust. The two of these forces are perpendicular to the air flow. Drag is a consequence of the production of lift/thrust and acts parallel to the airflow. Other aerofoil surface includes tail-planes, fins, winglets, and helicopter rotor blades.
INTRODUCTION Aerodynamics is the study of how gases interact with moving bodies. Because the gas that we encounter most is air, aerodynamics is primarily concerned with the forces of drag and lift, which are caused by air passing over and around solid bodies. Engineers apply the principles of aerodynamics to the designs of many different things, including buildings, bridges and even soccer balls; however, of primary concern is the aerodynamics of aircraft and automobiles. THE BASIC FORCES OF THRUST,DRAG AND LIFT There are three basic forces to be considered in aerodynamics: thrust, which moves an airplane forward; drag, which holds it back; and lift, which keeps it airborne. Lift is generally explained by three theories: Bernoulli 's principle, the Coanda effect, and Newton 's third law of motion.
Introduction: The objective of this lab report was to observe a glider on an inclined air track and measure the amount of time it takes to travel from one point to another. The use of an inclined plane helps us study the correlation between the elevation of the incline and acceleration down the incline, which can be used to determine the acceleration caused by gravity. As we increased the height of the incline, the acceleration also increased, thus making the glider go faster. This helped us verify Newton’s second Law of Motion to a certain degree. Theory: The principle we tested in this lab was Newton’s second law that states the net force on an object is equal to the mass of the object times its acceleration (F ⃗=ma ⃗).
Until today, despite successful prototype testing, there are still many skeptics about the ability of Lilium jet to achieve vertical flight but in order to achieve this, the team has engineered a perfectly light yet efficient 36 engines to lift the jet and this is achievable since it is only 600kg two-seater jet. The fan engines are pointing downwards so that when the jet hovers and climbs upward, the fans would turn backwards slowly, which would then push the jet into forward flight. Upon achieving horizontally oriented engines, the aircraft would fly just like a normal plane so it would be easy to navigate especially for experienced pilots. The throttle stick and on-board computer make everything just within your reach. So, aside from being a great innovation, Lilium would always stick with its first and primary goal of giving the utmost convenience for the people.
The U.S. has the strongest and most advance military in the world. The U.S. military did not get that title through careless selection of innovations and inventions. The military got that title because it knew a good advantage when found. Today, an advantage has been found and it comes in the form of a plane with no man in it. It is called an unmanned aerial vehicle (UAV), now do not be mistaken there is always a person controlling the aircraft.
To build such a monumental plane, workers and designers had to construct perfect dimensions within the blueprint. High speeds have been reached along with one of the best UAV systems in military existence. First built in 1966, technological advances have improved the aircrafts performance and abilities. Interesting records and feats to mankind have been accomplished with this piece of art along with many “war stories” from the pilots who have been in the
General Thomas P. Stafford was a pretty outstanding astronaut and man. He always worked hard and tried his best. The hard work paid off when he received his doctorate of laws, one of science, another for aeronautical engineering, and another in communications and humanities. This shows that Stafford was pretty well rounded in the subjects and that he was dedicated. These facts interested me because of two things.
