Overview
Am a boy with a big imagination. Ever since my childhood I wanted to be a pilot. In my childhood I traveled a lot and I had the opportunities to go visit the pilot while the plane was in the air. Even though it was really exciting, in my head it wasn’t the felling that I wanted. The closes way I got to being a pilot was a toy helicopter with a remote control. It allowed me to control the speed and the direction. So when our teacher asked as to write an essay, I went on internet to search for some stimulus. I always wanted to become a pilot, but I never thought on how the plane works. Likely I found one experiment close to how a plane works “fun with a toy helicopter”. It immediately caught my attention. With a deep research in it, I was able to find an equation that was a major key of my investigation and to know what area am going to be focusing on.
How does a helicopter lift vertically with some thin roto blade currying all that mass?
My aim was constructed as the following. What is the correlation between the helicopter theory and my investigation? To be

The first operational helicopter was the forcke-wulf fw 61 in 1936. Most of the helicopters meet the limits production, however it was not until the 1942’s that a bright man named Igor sikorsky designed a helicopter and the production escalated by around 131 aircraft built. In the early design a helicopter had more than one rotor. But it is the single roto with the anti-torque tail roto configuration that caught people intension.
A helicopter 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 forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot
In addition to all of these great features, the Heli-Max Novus 125 CP mounts a powerful 10,000kV brushless electric motor and a solid electronic speed control. This means that this RC helicopter is equipped to be one of the most powerful...
Lindbergh’s passion for mechanics didn’t come as a surprise to many. As a young boy, Charles seemed to be very interested in the family’s motorized vehicles, such as the Saxon Six automobile and Excelsior motorbike. But after starting college in the fall of 1920 as a mechanical engineer, his love for aviation started to bloom. Deciding that the field of aviation was more exciting, he dropped out within 2 years. He then decided to take lessons at the Nebraska Aircraft Corporation’s flying school and was up in the air for the first time on April 9, 1922 when he was in a two seat biplane as a passenger. But his solo flight would not be until May 1923 at the Souther Field in Americus, Georgia, an old flight training field where Lindbergh came to buy a World War I Curtiss JN-4 “Jenny” biplane. It only took half an hour to practice with another pilot at the field to decide that Lindbergh was ready to fly the plane himself. After a week of practicing, Lindbergh took off on his biplane on his first solo cross country flight and few weeks after that, achieving his first nighttime flight near Arkansas, both marking huge milestones for the young pilot.
The history of flying dates back as early as the fifteenth century. A Renaissance man named Leonardo da Vinci introduced a flying machine known as the ornithopter. Da Vinci proposed the idea of a machine that had bird like flying capabilities. Today no ornithopters exist due to the restrictions of humans, and that the ornithopters just aren’t practical. During the eighteenth century a philosopher named Sir George Cayley had practical ideas of modern aircraft. Cayley never really designed any workable aircraft, but had many incredible ideas such as lift, thrust, and rigid wings to provide for lift. In the late nineteenth century the progress of aircraft picks up. Several designers such as Henson and Langley, both paved the way for the early 1900’s aircraft design. Two of the most important people in history of flight were the Wright Brothers. The Wright Brothers were given the nickname the “fathers of the heavier than air flying machine” for their numerous flights at their estate in Kitty Hawk, North Carolina. Orville and Wilbur Wright created a motor-powered biplane in which they established incredible feats of the time. The Wright Brothers perfected their design of the heavier than air flying ma...

According to Carolyn Daitch, Ph.D., director of the Center for the Treatment of Anxiety Disorders Helicopter parents refers to "a style of parents who are over focused on their children". She also added "They typically take too much responsibility for their children's experiences and, specifically, their successes or failures"(n.d). Helicopter parents is all about ‘hovering’ over their children in an effort to become involved in their life that involves over controlling and overprotecting. This is a control in order to protect their children from harm and disappointment in today’s society. These parents also find it hard to let go, won’t allow children to make their own mistakes in life and also placed their own identity
In 1957, the army began developing a new fighting force based on the helicopter. ...
First of all you will have to understand the principles of flight. An airplane flies because air moving over and under its surfaces, particularly its wings, travels at different velocities, producing a difference in air pressure, low above the wing and high below it. The low pressure exerts a pulling influence, and the high pressure a pushing influence. The lifting force, usually called lift, depends on the shape, area, and tilt of the wing, and on the speed of the aircraft. The shape of the wing causes the air streaming above and below the wing to travel at different velocities. The greater distance over which the air must travel above the curved upper surface forces that air to move faster to keep pace with the air moving along the flat lower surface. According to Bernoulli’s principle, it is this difference in air velocity that produces the difference in air pressure.
Planes have developed immensely through the years. The Wright brothers developed the first plane in 1903.
Thesis- The Wright Brothers took a stand in history by not only creating the first airplane but by developing aviation technology that influenced the modern world air travel
Milton Wright became a bishop in 1877 and moved his family to Cedar Rapids, Iowa. Milton traveled frequently on church business, and while he was away his wife Susan ran the home. She was very handy; she could fix most anything and make things, a very resourceful woman. The same year that the Wrights moved to Cedar Rapids Milton returned home from one of his journeys with a gift for his two youngest sons. The gift was a toy helicopter made of bamboo, cork, and paper. “The twin propellers on the helicopter were activated by a twisted rubber band, a type of propulsion popularized by a young Frenchman named Alphonse Penaud.” (Howard, 1987,1998, p. 18) The gift that Wilbur and Orville’s father gave to them was not only a small toy helicopter, it was a spark of many ideas to come in their...
“The US army used many different types of helicopters like the HU-1A. It had a T53-6-5 motor, which put out 700 horsepower and could hold up to 8,500 pounds. It was used as a transport and medical vehicle that was equipped with a 30 mm”. Bishop) “The US also used Agent Orange to kill the trees and plants in the area so it would be easier to spot the enemy from the air and the ground.” (History.com)
The most important factor in determining the lift generated by an airplane is the angle of attack. The angle of attack is the degree measure from the horizontal that a wing is elevated or declined. When the angle of attack is between 1 and 20 degrees, the most lift is generated. To find the lift generated by a particular area of wing in a standard airfoil shape, a teardrop with the fat end facing forward, the equation L=Cl 1/2 (pV2)S. Cl is the lift coeficent, which is determined by the shape of the airfoil and the angle of attack. P stands for the air mass density, V for the velocity of the air passing over the wing, and S for the area of the wing when viewed from above or below.
As termed from an encyclopedia article on parenting, helicopter parenting is an expression used in the media to express contempt or disapproval of parents. Helicopter parents simply watch over, or hover over their children and lead them from a better view to give advice. Helicopter parenting is not what it is depicted as; it is a style of parenting that creates a bond between parent and child that in most cases is beneficial in economic, social, and academic aspects of the child’s life.
Wings create lift for the upward force of an airplane. A great example of how this happens is sticking your hand out of a car window driving down the freeway. The force on your flat palm causes a force that can lift your hand up or down by changing the
The length of the helicopter rotors. The number of paperclips changes the acceleration force while the rotor length changes the resistance force. Finally, to make this a fair test I shall use the same helicopter throughout the experiment. The helicopter shall always be dropped from a height of two metres, as this continuity makes the experiment even more of a fair test.
