Vehicle Design and Threaded Sleeves
Image of main housing with threaded sleeves and threaded cap slid into the two angled cutouts. The IPAXs are secured by the two welded on hollows sleeves, one for each IPAX. The holes for the sleeves are cut at a 45-degree angle. Made of T6-60601 Aluminum. Modeled in SOLIDWORKS.
Image of threaded sleeve (in red/pink) and threaded cap (in blue/grey). Made of T6-60601 Aluminum and modeled in SOLIDWORKS. The exact threading size in terms of diameter and pitch is currently under redesign.
Housing cylinder tapered at top and bottom, so edges are smooth.
Mounting holes at the top and bottom.
6 Holes at the top: 3 for floats and/or foam to increase buoyancy of the vehicle, other 3 are for necessary tethers
Mounting holes at bottom for adding weights
Base functions like a “porthole window” on a submarine and allows IPAX to see through to take pictures.
Sleeve has a lid that screws on like jar.
Custom lid was designed that has internal threading that allows it to be screwed onto the top to stop the IPAX from sliding out of the top of the sleeve.
View of the base of the custom threaded sleeve with the IPAX inserted. The LED cameras can be seen, allowing light to shine through for the camera to utilize the lights for capturing images.
Bar 30 Depth/Pressure sensor secured inside custom screw lid.
Sensor sits outside the cap to be in direct contact with water, so it measures out the depth, pressure and time.
Water leaks through Porthole window at the base, so sensor will be submerged.
Section view image of threaded sleeve (in red/pink) with threaded cap (in blue/grey) screwed on. The Bar 30 sensor can be seen attached on the inside of the threaded cap.
Flow Simulation
Flow Simulation
Screenshot of flow simulation performed in SOLIDWORKS Flow.
A preliminary flow simulation was done on the first design of the Sleeved Hourglass model was done in order to get a general sense of how water flowed over and through the body as a whole.
The flow simulations showed us that the basic vehicle design allowed water to flow over it smoothly.
The rate of the water flow did not increase past the initial speed of the flow of the water that we had chosen.
