    Definition: A helicopter (or chopper‚ helo or whirlybird) is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically‚ to hover‚ and to fly forwards‚ backwards‚ and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would usually not be able to take off or land. The capability to hover efficiently for extended periods of time allows a helicopter to accomplish tasks

    Helicopters have a bad reputation. Many people unfamiliar with them think that helicopters are a collection of rotating parts‚ ready to fly apart and cause disaster at any time. Or they have seen a tail rotor shot off by a missile in an action movie and picture themselves spiraling to the ground‚ victims of inherent instability. People have had to make judgements about the riskiness of helicopter flight without good information‚ not because data about helicopter safety doesn’t exist‚ but because

    Helicopters Part 1 stimulus material: Research and collecting secondary data How the turning rotor makes a helicopter move upwards: The blades or rotors on a helicopter are used to produce a lifting force which gets the helicopter off the ground. As they spin around they cut into the air and produce lift‚ each blade providing an equal share of the lift. To produce this lifting force air must flow over each rotor. This is why the blades spin at an angle against the air. The shapes of the rotors

    Rotor Makes A Helicopter Move Upwards How Does A Helicopter Work? In order to fly‚ an object must have "lift." Lift is what pushes something up. Lift is made by wings. Wings have a curved shape on top and are flatter on the bottom. That shape makes air flow over the top faster than under the bottom. The faster air on top of the wing makes suction on the top of the wing and the wing moves up. Airplanes get lift from their wings. A helicopter’s rotor blades are spinning wings. A helicopter moves air

    Helicopters Back in the 1500’s there was a renaissance man named Leonardo Di Vinci‚ this man was the first man to develop and draw the idea of a machine that is capable of vertical flight‚ which we now know as a helicopter. His design would have worked‚ but only theoretically. Many others tried but were missing two things‚ the understanding the nature of lift‚ and an engine. At the end of the nineteenth century‚ the internal combustion engine made it possible for the development of full sized

    APACHE HELICOPTER ABSTRACT An attack helicopter provides battle commanders a tool for delivering surprise and shock effect to the enemy. This is because attack helicopters can be more readily deployed than any other weapon system in dealing with an armored attack. Attack helicopters become even more lethal when equipped with advanced sensors‚ more potent weapons and improved survivability. New communications systems allow these platforms to pass on battlefield information to other platforms‚

    Helicopter Lab * Objectives: the objective is to study the effect of variables on the helicopters’ flight. The goal is to observe which can stay in the air for the most time. * List of materials: 3 patterns for a paper helicopter‚ scissors‚ tape ruler‚ and paper clip. * Procedures: 1. Cut the solid lines and fold the dashed ones. Fold A toward you and B from you to form wings. Then fold C and D inward to overlap‚ forming the body. Fold up the bottom on the dashed line and hold it

    Helicopter Experiment Prediction: As the mass on the helicopter’s copters increases‚ the speed taken for the rotors to spin down faster‚ this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter
