Introduction A rotocopter is a smaller simpler version of a helicopter. The rotocopter displays two simple blades that are re shaped into a rectangle a circle and a triangle as the experiment is conducted. These results allow us to determine how the blade shape affects a rotocopter’s flight time. Although the helicopter looks to be complex and maculate the helicopter and the rotocopter have many similarities. Such as each depending on rotors and how the rotors are designed. The aircraft in

which is the airflow that caused by the forward motion of the aircraft. It acts in the direction that is parallel to the flight path but in the opposite direction. In this case, the force that acts perpendicular to the airflow will be equal to the lift force. However, for the ornithopters, there are two airflows passing through its aerofoil. The first component is the same as the normal aircraft. However, the second component

The development of airfoil sections began in the late 1800’s. Before the development, it was known that flat plate would produce lift when set an angle of incidence, however faithful to see that the curvature that resembled bird wings would produce more elevation and more efficient. In 1884, H.F Philips patented a series of airfoil shapes after testing them in one of the earliest wind tunnels. In 1920’s, a wide range of airfoils was developed based on primarily on trial and error. Figure 9, shows

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

depends on the lift. The lift is in the middle and starting point of the flight so the thrust can help the plane perform better. Another force that can effect the flight of a paper airplane is the force of lift. Lift is when the wing is getting pushed upwards harder than it is getting pushed downwards. If this is happening, then it means gravity is not as strong on the plane as thrust and lift are. Lift is the starting point and the middle of the flight. If the plane is moving upwards, lift is taking

Fluid Mechanics-II Project Farhan Akram Department of Mechanical Engineering College of Electrical & Mechanical Engineering National University of Sciences & Technology Rawalpindi, Pakistan farhanakram@outlook.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

composed of the four forces of flight that aerodynamics follow and these include: weight, lift, drag and thrust. On one hand, weight refers to the gravity forcing towards the center of the earth. This counts the people inside the airplane, its lift-designed wings, the baggage and the freight. Due to its large scale, it allows the airplane to move down. This is adjacent to another aerodynamic-force called lift. This force usually comes from the

maneuvers that help them in their journeys. Some of the likes as decreasing their surface area to decrease drag across the opposing flow of the fluid. They achieve this by closing their wings, which will increase their speed. They also try to increase lift by rapidly flapping its wings to push it upwards. As stated later, they also use their large flight muscles to produce thrust that allows them easier passage. Another very important strategy that large winged animals use is the soaring one. Their large

Flying in the Theatre A system of ropes, pulleys and counterweights is used in a theatre in order to lift scenery, flats and sometimes people among other theatre hardware. This system is commonly known as a fly system or a rigging system. Flying people can be a dangerous act and must be carried out by a competent person with adequate training and experience. A fly system consists of battens, lines (made of both hemp and wire), blocks, a cradle and counterweights. When flying people a harness is also

Flight is caused by the four forces, lift, drag, weight, and thrust. Lift is the upward force that pushes a kite into the air. Drag is the backwards force that acts opposite the direction of motion and is caused by the difference in air pressure between the front and back of the kite. Thrust is the forward force that moves the kite. It is caused by the moving air/wind. Weight is the downward force caused by the gravitational attraction of the Earth. 3. What does the design have to do with the kite’s

Can different wing designs have more lift? Flying is one of the things that can terrify most people, but there is nothing really to be afraid of while flying. In a car, you have a lower chance of death or injury on an airplane, than in a car. Airplanes need something called lift to stay in the air, air is also needed because without air there would be no air resistance, or drag to hold the airplane in the air. Lift is a very important part for an airplane, lift on the airplane is generated by every

Wooosh! Is the sound of water shooting into the tube of a Flyboard. You are about to fly into a world of flips and spins. As you most likely guessed we are talking about the extreme sport Flyboarding. This paper is going to be about how it works and other things to do on it. So we are going to talk about Flyboards. Cool Things to Do One cool thing that you could do on it when you can fly well on it is you could fly thirty feet in the air.You can also do cool

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. Control surfaces (e.g. ailerons, elevators

was innovative and brilliant. The Wright brothers design included detailed plans for the engine and propellers, the controls, and the body of the plane. Orville and Wilbur Wright designed their plane in Dayton, Ohio and then traveled to Kill Devil Hills North Carolina to finish assembling the plane. The engine of the Flyer I was a twelve horsepower gasoline engine that powered the propellers of the plane. A sprocket chain connected to the propellers and to the engine made the propellers spin. The

for the drag polar of the NACA 0012 airfoil by measuring the lift and drag coefficient of the airfoil in the wind tunnel. The drag polar plots was computed using force balance and wind tunnel environment. The drag polar were simulated using the Reynold’s numbers of 50000, 100000, and 150000 at angle of attacks from -15 to 15 with one degree increment. The plots were created by mainly using the calculated values for the coefficient of lift and the coefficient of drag and their respective uncertainties

Parachute Investigation Lab Report Research Question and Background Information: Is size important for slowing done a parachute’s fall? Does it even matter? As the parachute is falling, the force of gravity is pulling the parachute down towards the Earth and this sometimes causes the fall to happen very fast. When going skydiving or when NASA tries to land a probe, designing a parachute is a vital step. Without the proper parachute, one could die or get seriosuly injured. The main use of the

The lift and drag characteristics of NACA 0012, 1408, 2412, and 4412 airfoils are characterized using a 6” by 6” subsonic wind tunnel equipped with a force balance. The axial and normal forces on the airfoil are measured at angles of attack ranging from -8° to 28° and used to determine lift and drag forces. Lift, drag, and drag polar curves are generated using experimental data. Lift coefficients are found to increase linearly with increasing angle of attack up to the critical angle of attack. Drag

the tractive force between tyre and road in order to obtain highest cornering and braking force. It was only achieved by implementing the wing on the car. The next challenge for the engineers was to overcome the lift forces on the car. In order to achieve maximum downforce and decrease lift force during braking and turning, engineers started to implement the wing and spoiler on the front and rear deck of the

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,

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. [1] The only variables the can easily be changed without reconfiguring the aircraft is velocity and as such
