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 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

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

The constant high-profile of helicopter accidents‚ such as the recent crash of the deadly medical helicopter in Oklahoma City‚ suggests that they are potential risk-makers. With a well-trained pilot and a helicopter that will operate properly‚ these incidents would most likely not occur. The major reasons that cause the helicopter accidents are the helicopter’s inherent flexibility‚ low visibility conditions‚ and the fact that they usually maintain a short distance to the ground. Due to these reasons

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

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

Pilot When there is a car crash on the highway‚ everyone slows down to gape at the wreckage. However‚ few have ever seen a truly horrific‚ heavily gory accident in which a Medivac helicopter has come to rush victims off to safety. Air-medical transport saves lives every day in a plethora of situations. Being a part of the Hawaii Air Ambulance team allows one to be the best pilot they could be in a field whose purpose is saving lives. To be an Emergency Response helicopter pilot requires an extensive

Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation‚ could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of the helicopter on terminal
