Why do boomerangs come back? When I was young, I thought boomerangs were magical. I wasn’t sure if they actually worked in real life, so I decided to make my own to test the idea. I took a pizza box, cut out a boomerang shape from it, and threw it. It didn’t come back. I tried again and again, but I couldn’t make it work. I was bewildered as to why my boomerang didn’t come back! As it turns out, I had constructed it incorrectly. I thought a boomerang was just a flat, v-shaped piece of material

of turbulent wind loads on high-rise buildings in one of the frequency domain analysis to get Peak Dynamic Response (PDR). This simplified method is developed by using the Power Spectral Density Analysis in Sap 2000. The turbulent wind spectrum, aerodynamic admittance and vertical coherence for buffeting wind loading are estimated using Kaimal spectrum, empirical relationship proposed by Vickery and Spatial Coherence of Davenport . The building models conditions are documented as a data bank. Then

In these years student are introduced to subject that are basic to engineering and subject that are specially related to aerospace engineers. These subjects include aerodynamics, structural analysis, fluid mechanics, flight vehicle design, flight mechanics etc. (Aerospace Engineers). Some universities allow students to enroll in five year program that earns bachelor’s degree and master’s degree at the end (“Aerospace

jet aircraft, the aircraft wings are not only designed to provide the necessary lift during the different phases of flight, but also have a variety of other roles and functions. Wing Support: Cantilevered -All the structure is buried under the aerodynamic skin, giving a clean appearance with low drag. A cantilever is a rigid structural element, such as a beam or a plate, anchored at only one end to a (usually vertical) support from which it is protruding. When subjected to a structural load, the

project I need 3 different sheets of paper,(Construction paper,Computer paper,Line paper, a notepad, a meter stick and a pencil. I chose this topic because paper airplanes always interested me in how they move and fly. I am also interested in the aerodynamics of the plane and how it can fly and move around with the air under its wings. In Ellis’ project Ellis is changing the weight of the paper airplane. Weight is a person's relative mass or weight which can be measured. Ellis

farthest but it did not because it kept hitting the walls and roof which stopped it from flying. RESEARCH Paper just does not fly on its own, but when if is folded and cut in the proper way it will fly or glide. Airplanes have four forces. The aerodynamic forces. Thrust, lift, drag, and gravity(weight). They help the plane maintain its air time. When the plane is thrown it is called thrust. Lift if what pushes the plane in the air.The size of the wings could contribute to its lift. Gravity(weight)

INTRODUCTION TO DELTA WING: The with Planform area in the shape of a Triangle is called a Delta wing. Supersonic flow is completely different from subsonic flow in many respects. Such differences impact the design philosophy of aircrafts for supersonic flights in comparison to subsonic flight aircrafts. Our study deals with the design and subsonic flow over a delta wing. Supersonic aircrafts usually have highly swept wings. A special case of that with triangular planform is called a delta wing. Though

direction. If you had fins in a non-equal position they might act up, causing the the spacecraft to crash. Some fins on a rocket need pressure to take action. This works because when a rocket is going into space it needs to have pressure so the aerodynamics of the ship will be able to fly where it is intended to go because you probably don't want to have a semi uncontrollable ship/spacecraft. Like I said earlier you need to have them spaced out in a reasonable amount so about 120

Running head: BALSA GLIDER PAPER 1 1 Balsa Glider Paper 1 Dylan Bryant Middle Tennessee State University BALSA GLIDER PAPER 1 2 Balsa Glider Paper 1 Goal (1-3 Sentences) My goals for this project are to have fun, build a successful glider, and try to win. I am a very competitive person and I will do my best to try and show it. I’m hoping through trial and error that I will achieve my goals. Requirements and Restrictions (2-3 sentences) To make this project fair to everyone, there are some restrictions
