This is going on a bit of a break for the moment because Arjun is busy and we don’t have other people to support it atm. If anyone has a concern with that, please contact me directly.
Cabin
@Alison Thompson
Cabin design still underway!
@Evan Janakievski has been working hard on the !
Dimensions are more fleshed out now but something weird is happening with Evan’s PDM
@Georgia Vachon Westerlund Updates to CAD and some CFD simulation results:
Following the feedback from last week’s meeting, I made the front/rear panels 2 mm thick and the side panels 4 mm thick
Added a 50 mm (length tentative) to the top and bottom of the front/rear panels. This segment will be bent up into the cabin when it is assembled
Chose a bend angle of 20 degrees, this angle is tentative pending simulation results.
The part files in PDM have been updated in accordance with the design changes shown below:
Sketches of design changes
@Georgia Vachon Westerlund Ran a couple of preliminary aero CFD simulations
Took me a while to download and learn the software
Created a “control block” with similar dimensions to the cabin to be used as a basis for CFD analysis (CAD available in PDM as well):
Dimension Model used for CFD
Used Ansys fluent to setup meshing, boundary conditions, simulation domain, etc.
Results are as follows:
Drag coefficient of ~8.61
Lift coefficient of 0.00395 (negligible)
For future simulations, would like to determine the effect of the 20 degree bend angle on the lift/drag coefficients
New model has already been made, just need to run that simulation later this week and compare results to the control block:
Would like to evaluate the relationship between the bend angle and the lift/drag coefficients
Would like to evaluate how effective s-ducts would be (a bit more advanced, I’ll need to get more familiar with Ansys Fluent first).
@Sohee Yoon has taken on the Aero-Panel mounting and it’s looking great! Want to explain your ideas? ?
@Jason Li want to share your seat updates? I see some nice sketches in !
