Introduction
The experiment I am doing deals with mainly aerodynamics. Before we get into anything else, let me explain and define the terms you need to know before doing this experiment. The three main terms needed to further understand my project are these below.
Chord- The straight line width of the propeller at a given distance along the radius.
Twist- The local angle of the blade at a given distance along the radius.
Radius- The distance from the center to the tip, along the center line.

Now that those three definitions are listed above, let’s begin. As you may know, airplanes, or helicopters, which I am going to use in my experiment, use propellers which are mechanical devices for propelling a boat or aircraft, consisting

Imagine this: A helicopter with huge blades and a helicopter with small blades. They are the exact same size, besides the blades, of course. Ask yourself. Which one do you think would get airborne first, if it even can? Well the one with larger blades, of course. The one with the smaller blades probably wouldn’t even be able to go airborne due to the weight of the helicopter. I know this is correct because like I said in the beginning of this paragraph, the blade span is larger, making for more air thrust, which means higher voltage, making it more …show more content…
If the twist angle is too high, it will, believe it or not, decrease the efficiency because it would be a lot harder for the blades to cut through the air. If the twist angle is too low, it will also not help because it would be acting like there isn’t a twist at all and the propellers would be fully relying on the motor that is turning them. An ideal degree of an angle would be needed, probably depending on the size of the helicopter or the length of the radius. In my case, I am going to be using a model helicopter, probably about the size of around a foot. Remember, this is just an estimate because I am typing this now before I got the parts to start doing my
With nitro fuel prices rising, there has never been a better time to consider moving to an electric RC helicopter. One chopper that offers the RC helicopter pilot the opportunity to fly both indoors and outside is the Heli-Max Novus 125 CP. This micro helicopter is a durable platform that is a true joy to fly.
Gas powered RC helicopters are some of the toughest and most exciting choppers to take to the sky in the RC world. These birds exhibit all of the power, torque, and top-notch flight performance of their full-scale cousins in a small package that is simply amazing. While these helicopters may look similar to their electric counterparts, they differ tremendously in the fact that gas powered RC helicopters are the most realistic thing you can fly short of sitting in the cockpit of a full-scale high-performance helicopter. Overall, these RC birds offer their pilots the chance to experience first-hand the exhilarating excitement of flying a top-notch chopper.
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

Introduction to Aerodynamics Aerodynamics is the study of the motion of fluids in the gas state and bodies in motion relative to the fluid/air. In other words, the study of aerodynamics is the study of fluid dynamics specifically relating to air or the gas state of matter. When an object travels through fluid/air there are two types of flow characteristics that happen, laminar and turbulent. Laminar flow is a smooth, steady flow over a smooth surface and it has little disturbance. Intuition would lead to the belief that this type of air flow would be desirable.
The Curtiss P-40 Warhawk was a single-engine, single-seat, metal fighter plane and ground-attack aircraft that was made by the Americans. The P-40 Warhawk fighters first flew in 1938 and caught the attention of the United States Army Air Corps, who placed the largest fighter plane order it had ever made for fighters for a count of 524 at a cost of US$13 million. This was the earliest serious fighter in WWII and did its job until better fighters came out. It was known as a safe and secure aircraft that was able to fly pilots back home after being shot up in action. Many variants of this plane were later created. In addition, the shark teeth graphics were a big feature on this plane.
The angular deflection is taken to be the angle formed from the center of the handle to the position of the deflected corner. Both left and right vertical displacements are included in the equation to take the average vertical displacement in order to generate a more accurate estimate of the total angular deflection of the handle.
“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)
...of half-twists is cut in half along its length, it will result in two linked strips, each with the same number of twists as the original.
As the boomerang spins, the airfoils at its perimeter create lift. Our text, Physics: A World View, discusses aerodynamics and Bernoulli’s principle. It explains the relationship between the velocity of a fluid and the pressure that the fluid exerts. A fluid gains energy when it speeds up as, for example when it goes through a constricting area in a pipe or passes around an airfoil. Since the gravitational potential energy is constant, the change is in kinetic energy. Since there is an acceleration of the fluid, the press...
The helicopter flies up to about 19,000 feet and, you know the air at this altitude is very thin. So it requires a helicopter to utilize more power to stay aloft up there. So, you know, you can imagine, if you add weight, it’s going to lose lift.
The Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter.
