DEN 302 Applied Aerodynamics SURFACE PRESSURE MEASUREMENTS ON AN AEROFOIL IN TRANSONIC FLOW Abstract The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases

counter. Place the sample of gold (Au) in the sample dish by double-clicking on it Zoom Out. Double-click on the petri dish to move it to the stockroom counter. Click the green arrow to Return to Lab. 2. Drag the petri dish to the spotlight near the balance. Click on the Balance area to zoom in. Drag the gold sample to the balance pan and record the mass in Table 1. 3. Click on the red disposal bucket to clear the lab after each sample. Repeat for lead (Pb)‚ uranium (U)‚ sodium (Na) and a metal of your

A day at the drag races is filled with excitement. There is the roar of the engines and the smell of tire smoke and racing fuel. The crowd can feel the rumble of power as the Top Fuel Dragsters stage and get ready to race down the strip. Safety Regulations are a big deal because They can go Three Hundred and Thirty +MPH so safety regulations and cutoffs for battery and transmission are necessary. Safety components are important‚ in case something goes wrong‚ a wreck can be prevented as much as

INTRODUCTION Traffic jams are the bane of any commuter. Many of us spend an hour or so stuck in traffic every week. The growing population is partly to blame for our congested roads‚ but the main problem is that we are not expanding our transportation systems fast enough to meet ever increasing demands. One solution is to create a new type of transportation that doesn’t rely on roads‚ which could one day make traffic jams a 20th century relic. To do this‚ we must look to the sky and water. WHY

The pursuit of a fixed definition to the Australian identity has been a controversial journey‚ and the identity remains as elusive as ever today. For that reason‚ the theme of the 2009 Brisbane Film Festival will be Australian Identity in Film – A Retrospective‚ as we hope to explore the ways in which Australian feature films have helped shape the complexities and diversity of Australia’s culture and identity. In particular‚ the festival will explore the diverse representations of homosexuals in

identify the forces acting on the ball at any given time‚ there are three forces‚ and they include: the vertical component of drag (F_(drag y))‚ the horizontal component of drag (F_(drag x)) and force due to gravity (F_g). In the horizontal direction‚ the forces sum up to be: ∑▒F_x =-F_(drag x)=-1/2 pv_x^2 C_D A In the vertical direction‚ the forces sum up to be: ∑▒F_y =F_(drag y)- F_g=1/2 pv_y^2 C_D A-mg The net-force acting on the ping pong ball is F=ma according to newton’s second law which states

Measurement of the distance a paper airplane will fly in a controlled environment UBT1 Task 2 Western Governors University Introduction: This report describes an experiment to show what types of paper airplanes will fly the furthest while meeting certain controlled variables. While the general term of flight refers to all aircraft‚ the experiment does not deal with powered aircraft. Due to this‚ paper airplanes should be looked at more like a glider or sailplane.(Aerodynamics of flight‚ n.d.) Considering

Regular cars usually have a shape to produce less drag‚ racecars however have a shape to help create negative lift on their bodies. Hucho‚ W.‚ & Sovran‚ G. (n.d.). AERODYNAMICS OF ROAD VEHICLES. Retrieved May 18‚ 2017‚ from http://www.academia.edu/9462450/AERODYNAMICS_OF_ROAD_VEHICLES Aerodynamic drag is made of two forces: the force of air pressure drag‚ and surface or skin friction also known as direct friction. Wheels are also a factor in drag as when they spin they cause friction. Science of
