I've spent a few hours digging through RASAero, Open Rocket, BurnSim, the Mass Budget, and hitting all of the above with healthy doses of common sense. Andrew gave me a few good ideas on where to start sanity checking our numbers. I know these values still sound on the high side, but I'm inclined to believe them pending flaws in the sim files. I would be very happy to hit 80% of these values though, knowing how these kinds of flights go.

In case anyone was curious, the rocksim file the previous rasaero numbers were based off of still was using an off axis piston and was almost 2 feet longer than the current design. This has led to some stability problems with the current design. At Burnout we hit a stability margin of 1.11. As this happens at Mach 3.35 I think we should increase the fin size to compensate.

These files are now correct to the design, as I understand it.

Motor file: 70kNs Rev 6

Composite Fin Can, OD of fin collar 6.25 in, 1/4 thick fins. .75 in edge chamfer .05 in rounding on edges.

Surface Finish: Rough Camouflage Pain

Rocket Length 11 feet 8 inches

GLOW is 158 lbs according to Mass Budget

Aft Closure include Boat Tail to 5.6 in aft diameter

Here are the relevant quantities. 

GLOW: 158 lbs, +/- 14 lbs  

Burnout Altitude: 12,200 ft AGL

Burnout Velocity 3,700 ft/s (Mach 3.35)

Maximum Altitude: 125,600 ft +/- 23,100 ft (from mass deltas)

These values came from some hand runs of RasAero

The next set of values came from OpenRocket on a dataset of 500 runs through Cassandra (Thanks Josh!). The raw values are quite different than the Open Rocket values, but with a healthy fudge factor (screwing with finishes and fin thicknesses) to get supersonic cd's to match those of RasAero, the numbers were similar. Second semester we should improve Cassandra's aerodynamics. Anyways, Cassandra gives the following

GLOW = 158 lbs

Apogee 131,529 +/- 6,443 ft

Median Apogee = 133,142 (An average flight is pretty close to the average of the flights, which is good)

3-Sigma Altitude = 138,870 ft

Landing Zone = 4.3 miles east of base camp +/- 1.4 miles
