New Payload Discussion

Proposed Payloads

Payload	Comments	Pros	Cons	Deal breakers
Spinal Compression
Peltier Power Generation	$\begin{array}{l}\eta_{thermal}\end{array}$ ~ 2% Assuming Ambient nose cone temp is ~90F and nose cone wall reaches $\begin{array}{l}T_g\end{array}$ of the composites at 330F we have a 250F gradient to work off of. Extrapolating from commercial power generation units we can expect ~.4A at 3.3V with the best case temperature gradient. 1 2 COTS generators appear to be implemented to work off ~600-800 F differentials, modify COTS unit?
Solar Irradiance Falloff Detection	Easily implemented with COTS parts. 1 Requires a window in nose cone. Window could be complicated to implement. 360 degree window and optics system or interpolation required.
Piezoelectric Beam Damping	Engineering space poorly defined. Lack of theoretical models to design system
Microgravity Fluid Transfer	PMD's are a PITA to design. Otherwise all COTS parts
Reaction Wheels	Must be inhibited until after apogee for FAA/ESRA compliance. Potentially compounds/introduces vehicle risk. Closed form mathematical engineering space.
High Altitude Gas Sampling
Culture Cell Flight
3-axis Stabilized Camera	Requires window in nose cone. Potentially COTS unit.
High altitude air sample - DNA sequencing
Radar Altimeter - IAP Class?	Homebrew radar range finder/mapping
