CATIA Electrical Harness

This is and electrical harness created in CATIA. It was made by using the Electrical Harness Assembly and Flattening workbenches.
The harness is composed of:
-GPS unit (top)
-PS-5a Connectors (bottom left and middle)
-Processing unit/fuse/diode (center)
-Switch (right)


The harness was then converted into a 2D drawing for easy assembly. 

E-mail me if you would like instructions on how to make these.

Nights in Los Angeles

This photo was from the griffith observatory using a 6 second exposure. Notice how there are airplanes "streak lines" above the city. If the altitude or exact location of the aircraft was know. Speed can be calculated from this image.

Supersonic Nozzle

By using the method of characteristics (a method used to solve hyperbolic partial differential equations),
Characteristic lines were found and plotted in Matlab for both a 15° conical and minimum length nozzles.
Temperature and pressure were also plotted

SpaceX's Dragon Capsule

This capsule is currently on a commercial resupply mission to the ISS

The dragon space capsule is designed to meet the Commercial Orbital Transport Services (COTS) requirements for transport to the International Space Station. The capsule’s main mission is to resupply the International Space Station (ISS).  Specific mission requirements were taken from NASA’s SSP 50700 document.  These requirements include handling capabilities, abort provisions, carrying capacities, and communication standards. The Dragon capsule has successfully flown two flights with a third planned. For the resupply mission, the dragon capsule is launched on a Falcon Nine launch vehicle designed and built by SpaceX. From launch to its 370km low earth orbit rendezvous with the international space station the mission is monitored at SpaceX’s mission center in Hawthorne, CA. The capsule’s payload includes: crew supplies, vehicle hardware, computer resources, spacewalk hardware, and Russian cargo. The dragon capsule consist of two articulated solar panels, four lithium polymer batteries, eighteen Draco thrusters, two compartment (one pressurized and one unpressurized) for cargo transport,  and onboard encryption/decryption systems. The capsule has a total volume of 25 m3, including the unpressurized trunk. It has two solar arrays that can generate up to 2000 W of power. With the stored propellant it can achieve 700 ,π‘š-𝑠. of Ξ”v for its on orbit maneuvers.
