\subsection{Survey of Existing Approaches} \label{ssec:existing} Because few remote control (RC) setups allow for live telemetry‚ almost all flying is done "by eye‚" and RC instrumentation and data logging is a poorly developed field. RC gliders especially eschew any projecting elements which could increase drag. The few relevant RC systems the author has found are described in this section‚ but most considered designs are in practice found only on manned vehicles. \begin{figure}[!htb]

Prac Report – Investigating Parachutes Experiment Aim: To measure how the size of a parachute t’s surface area affects the parachute’s speed‚ acceleration and time of flight. Hypothesis: A parachute with a larger surface area would fall slower due to that fact there would be a higher level of drag‚ or in other words more air resistance. Materials: * Sturdy garbage bags * Metric ruler * Scissors * Washers * Twist ties * Light-weight string * Stopwatch Method:

The advantages and disadvantages of travelling by airplane As well as being very exciting‚ airplane travel really can be one of the most efficient ways to travel around the world. The availability of cheap air travel means that it is now easy for almost anyone to fly anywhere. We will now look at the advantages and disadvantages of air travel. The Pros of Travelling by Airplane. Nobody can doubt the fact that our lives have been changed by air travel. It is much faster to travel by plane; it is

Alixandria Zeidel Physics 131 – section LZ Hasbrouck 208 10/01/14 Forces and Newton’s 2nd law Abstract The purpose of this lab was to learn about how force influences acceleration. A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both

When the gas rushes out of the balloon’s mouth it moves forward which starts a movement called thrust. Thrust requires both energy and direction. When the air moves out in one direction from the balloon‚ it flies in the opposite direction. This is an example to Newton’s third law of motion‚ "To every action there is an equal opposite reaction." The characteristics to explain that an Action Force results in a Reaction Force are that the two forces should be equal in magnitude. The two forces are in

Discussion: As shown in the result section‚ the drag force increases steadily with increasing wind speed. However‚ for high wind speeds with largest sphere‚ this is not true. There is a region that the sphere experiences a large drop of drag force. The drag coefficient remains relatively constant for most cases. However‚ when a Reynolds number reach about 300‚000‚ and the sphere is the largest one; for this case‚ the drag coefficient drops abruptly. We also found that for the same wind speed‚ the

The definition of honor is to be highly respected or privileged. To me honor means that you have full respect for someone‚ but if you are the person that is displaying the honor you should have a good attitude‚ a reason for people to want to look up to you‚ and always be accountable. Wilbur and Orville Wright were American inventors and pioneers of aviation. In 1903 the Wright brothers achieved the first powered‚ sustained and controlled airplane flight; they surpassed their own milestone two years

We owe it to aerospace engineers because “Few disciplines have inspired humanity as much as aerospace engineering. Many of the technological advances that are now part of our daily lives‚ such as handheld calculators and non-stick pans‚ were initially developed to aid in space flight. Today’s aerospace engineers are still working to help us view the edges of the universe as well as improve the way that we live our lives right here on planet earth.” (Peterson’s staff) This quotation proves that Aerospace

Time had it that there was a youth named Samuil; Samuil was said to carry out the impossible. Though there was another child named Kendrick. They both attended Karoukin Charter School in Minsk‚ Belarus. Kendrick was fairly unpopular to that of Samuil’s state and only had three good friends‚ Darya‚ Uladzimir‚ and Maksim. One morning in Calculus II Samuil made a paper airplane that flew perfectly straight down the main hallway; a staggering 70 meters! Kendrick became very jealous about what Samuil
