Activity 1.2.1 Aircraft Control Surfaces and Components
Description: In this activity you will identify the components of an aircraft. You will explore aircraft control and stability about the threes axis of flight. Aircraft also deflect airflow to change direction. Conclusion Questions: 1. I have observed the Canard style aircraft. The Canard has the horizontal stabilizer in the front of the plane. It looks really awkward. 2. Improvements in stability, airfoils, wings, and cockpits could impact the design. Smaller planes could fly faster. Activity 1.2.2 Center of Gravity
Description: The center of gravity is where the mass of an object is concentrated or balanced. Therefore, an object tends to rotate about that point. Air resistance affects this rotation. In this activity you will calculate the location of the center of gravity for an aircraft which affects its stability. Conclusion Questions: 1. The weight is the main factor that changes the center of gravity. The distance of the weight form the engine is another factor. 2. The center of gravity is important in the stability of the plane. The aircraft could be unstable and go down. Make sure your aircraft is safe. |

Activity 1.2.4 Atmospheric Conditions
Description: In this activity you will calculate the pressure and temperature at various altitudes. Due to the Earth having a blanket surrounding it called the atmosphere there are many different atmospheric factors that affect temperatures and pressure. Conclusion Questions: 1. The temperature lapse rate will affect design because the aircraft needs to be able to function at different temperatures. 2.The pressure lapse affects design because the pressure of the aircraft needs to be kept constant to fly safely. the materials will most likely be changed. Activity1.2.5 Aerodynamic Forces
Description: Aircraft take flight through their ability to generate lift. As fluid flows over an airfoil, lift and drag are generated, which can be calculated using the lift equation. In the activity you will calculate various lift and drag using the lift equation. Conclusion Questions: 1. As the coefficient of lift changes so does the amount of lift being applied to the aircraft. When the coefficient of lift goes up so does the lift. The more lift an aircraft has the less speed they need to land. Speed causes lift, so the more lift the less speed you need to counteract the lift. 2. Basically, any factor could have changed the drag. Mainly the velocity and coefficient of drag changed the drag in this calculation. 3. The amount of drag on the aircraft is extremely huge. Activity 1.2.10 Glider Design Challenge #1
Description: Have you ever tried to fly a glider? Have you made something with balsa wood before? In this project you will learn to do both. This design challenge provides glider constraints to create a glider design using the AERY software package. Conclusion Questions: 1.The word aft was difficult at first, but now I know it means back. 2. My design is precise, but not very hard to make with the software. 3. In order to get my glider to fly it was a trial and error process. I kept changing the glider to adjust to the constraints. Activity 1.2.11 Glider Design Challenge #2
Description: In this project, you are going to expand your knowledge through more advanced skills while refining your glider design. This is an importance design step of refining and testing a design to improve your design concept. Conclusion Questions: 1. With the second design we were told to change as little as possible. Those constraints made designing the glider hard to achieve. 2. Due to the constrains I only changed a couple of the dimensions compared to the first design when I changed anything to get it to fly. |
