Title          
Aerodynamics 
   
 
Abstract    
Aerodynamics (shaping of objects that affect the flow of air or gas) is a branch of fluid dynamics concerned with the study of forces generated on a body in a flow. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. The use of mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for heavier-than-air flight.


Airflow across an aircraft wing. A greater angle deflects air downwards at a geater angle to increase LiftAerodynamic problems can be classified in a number of ways. The flow environment defines the first classification criterion. External aerodynamics is the study of flow around solid objects of various shapes. Evaluating the lift and drag on an airplane, the shock waves that form in front of the nose of a rocket or the flow of air over a hard drive head are examples of external aerodynamics. Internal aerodynamics is the study of flow through passages in solid objects. For instance, intern...

Title          
CEV NASA space launch rocket trip to moon 
   
 
Abstract    
The Draft Statement of Work for the CEV was issued by NASA on December 9, 2004, and slightly more than one month later, on January 21, 2005, NASA issued a Draft Request For Proposal. The Final RFP was issued on March 1, 2005,[2] with the potential bidders being asked to answer by May 2, 2005.

NASA had planned to have a suborbital or an Earth orbit fly-off called Flight Application of Spacecraft Technologies (FAST) between two teams' CEV designs before September 1, 2008. However, in order to permit an earlier date for the start of CEV operations, Administrator Griffin had indicated that NASA would select one contractor for the CEV in 2006. From his perspective, this would both help eliminate the currently planned four-year gap between the retirement of the Shuttle in 2010 and the first manned flight of the CEV in 2014 (by allowing the CEV to fly earlier), and save over $1 billion for use in CEV development.[3]

On June 13, 2005, NASA announced the selection of two consortia, Lockheed Martin Corp. and the team of Northrop Grumman Corp. and The Boeing Co. for further CEV development work.[4] Each team had received a US$28 million contract to come up with a complete design for the CEV and its launch vehicle un...

Title          
Phoenix Launch 
   
 
Abstract    

Phoenix Heads for Mars, Spacecraft Healthy The Phoenix spacecraft has separated from the Delta II rocket and ground controllers at NASA's Deep Space Network .

Phoenix was a robotic spacecraft on a space exploration mission on Mars under the Mars Scout Program. The Phoenix lander descended on Mars on May 25, 2008. Mission scientists used instruments aboard the lander to search for environments suitable for microbial life on Mars, and to research the history of water there.

The multi-agency program was headed by the

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          
Test of Rolls Royce Engine for Airbus 380 
   
 
Abstract    

A Discovery Channel footage of a destructive testing of a Rolls Royce jet engine. The idea is to see if the engine suffers a destructuve failure, all the fragments from the failure (blade parts, lethal shrapnels) are contained in the engine cover. This is an important part of the testing that ensures safety for passengers.

Rolls-Royce plc (LSERR.) is a British aircraft engine maker; the second-largest in the world, behind General Electric Aviation. The company has related b...

CFD simulation of vortex shedding @ Re=100 
   
 
Abstract    
Numerical simulation of vortex shedding in flow past circular cylinder at Re=100, plotted is the magnitude of the X-velocity component. At the end some passive actuation is imposed on the cylinder boundary, in the end the goal is to attenuate the vortex shedding using this jet.

Title          
Smoke flow visualization over an Airfoil 
   
 
Abstract    

In general, flow visualization is an experimental means of examining the flow pattern around a body or over its surface. The flow is "visualized" by introducing dye, smoke or pigment to the flow in the area under investigation. The primary advantage of such a method is the ability to provide a description of a flow over a model without complicated data reduction and analysis.
