Accomplishments/Updates/News: (details below)
- Kickoff meeting with sponsor (Ernest and Christina)
- Prototypes might need to be tested on-site
- Need to be escorted while there
- Meeting with Anderson
From meeting with Dr. Anderson:
- Become (semi-)experts: materials, sensors (possibly passive), mechanical methods, other ideas?
- Space needs: pneumatics testing equipment; Is heat testing on campus possible? Cold?
- Can we play with the pressure of the pneumatic arm? How much pressure is required to
overcome the combined force of all the springs/friction/etc?
Materials concerns:
- Thermal properties: Coefficients Of Expansion (COE); failure at temperature extremes
- Hardness (e.g. for pins at mechanical stops)
sensors:
- dropbox has some fiber optic sensors. Useful to us?
Questions for Ernest:
- How did the pins at the hard stops come out? Did they break? Were they threaded and
just unscrewed themselves
- Material preferences? Does anything fly within the budget?
- Can we use more brass-on-steel for sliding parts? (currently a plastic material (?)is
used for some of the sliding bearings)
- Teflon? Graphite? (Will graphite require some cleaning or containment?) Other lubricant
ideas? Wet/dry preference?
- Can we get the prototype, pronto, for the presentation?
- In 'rotating shuttle temps.xlsx', what are the kit/sys offsets?
- Is overshoot an issue? (Material prop.'s)
- Was the heating in closed loop with respect to a different temperature reading than the
individual pucks? For instance, did it just heat for some time until the hot plate
had maintained a certain temperature for a certain amount of time? Because the set
point was 175 deg. Celsius, and the average high temperatures only reached about
115 deg. Celsius. When we come up with a new heat transfer scheme, will this just
be an issue of finding out the time required to maintain the hot plate at the
set point?
- Did we sign budget forms? Do we know the official budget? Other official paperwork?
- Will we need these to fabricate the plate?
@ ~\156B Group\90 degree part rotators\COTS\gun drills\deepholeflyer.pdf
Long holes in side of plate in the plane direction for the pressure sensors that would
produce suction when the slider was at +/- 45 degrees. Should we keep/change this design?
Ask Tom if/what else we would need to create these holes - PDF says a pilot hole is needed.
- What material is the solid plate?
Looking forward:
- Risk Reduction group presentation - Tuesday, Dec. 10th 2012 Finals Week Fall
