Title          
GRASP Lab UPenn 
   
 
Abstract    
This video premiered at the TED2012 Conference in Long Beach, California on February 29, 2012. Deputy Dean for Education and GRASP lab member Vijay Kumar presented some of this groundbreaking work at the TED2012 conference, an international gathering of people and ideas from technology, entertainment, and design. Flying robot quadrotors perform the James Bond Theme by playing various instruments including the keyboard, drums and maracas, a cymbal, and the debut of an adapted guitar built from a couch frame. The quadrotors play this "couch guitar" by flying over guitar strings stretched across a couch frame; plucking the strings with a stiff wire attached to the base of the quadrotor. A special microphone attached to the frame records the notes made by the "couch guitar". These flying quadrotors are completely autonomous, meaning humans are not controlling them; rather they are controlled by a computer programed with instructions to play the instrume...

Title          
Boeing 747 Wing Tip Vortex Test 
   
 
Abstract    
This 36 second movie clip shows the Boeing 747 Wing Tip Vortex Test. As part of the overall National Aeronautics and Space Administration (NASA) study of trailing vortices -- the invisible flow of spiraling air that trails from the wings of large aircraft and can "upset" smaller aircraft flying behind -- the NASA Flight Research Center (FRC) borrowed a Boeing 747 jetliner for testing. The B-747 had been purchased by NASA for the space shuttle program and assigned to the Johnson Space Center. Six smoke generators were installed under the wings of the B-747 to provide a visual image of the trailing vortices.

GE90-115B Gas Turbine Jet Engine Testing &amp... 
   
 
Abstract    
GE90-115B Gas Turbine Jet Engine Testing and Evaluation I takes a lot of money and time to test as thoroughly as the FAA, military, and GE require. More money and time and lives are saved by finding most problems before they become much larger. Some claim US gas turbine aircraft engines can't take turbulence or odd angles of attack. The claim is clearly false, if you note the shot of the crosswind testing fans. The crosswind fans can simulate hurricane winds at any angle. The fan and the engine can be pivoted to simulate any angle. Typically it is some former soviet block people that make those claims. They think just because they carelessly showboat fighters at air shows doing extreme AOA, that they are the only ones that can do so. The fact is that we don't make a habit of showboating at air shows because it is risky. The former soviet block has crashed a lot of fighters showboating extreme AOAs. The fact is any time you move a gas turbine with reverse airflow your risk of a flameout increases dramatically. The exhaust can recirculate back into the intake the result can be a backfire or flameout or just reduced power; all can be fatal if you are flying with no margin of error at an air show. Normally; US pilots a...

Title          
How Airplanes Fly 
   
 
Abstract    

The simple physics of aerodynamically generated lift and drag and other forces that enable an aircraft to fly is discussed. A fluid flowing past the surface of a body exerts a surface force on it. Lift is defined to be the component of this force that is perpendicular to the oncoming flow direction.It contrasts with the drag force, which is defined to be the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force. An

Title          
Theory of Lift Generation - Airfoil 
   
 
Abstract    

There have been varies theories explaining the production of lift by an airfoil. Interestingly, many rather most of these have been misconceived and hence are false. This lists the major theories proposed and the drawbacks they suffer finally leading to a correct acceptable theory.

A fluid flowing past the surface of a body exerts a force on it. Lift is defined to be the component of this force which is perpendicular to the oncoming flow direction.[1] It contrasts with the drag force, which is defined to be the component of the fluid-dynamic force
