Description:
We are looking for suppliers of flywheel energy storage modules suited for the following requirements for a lunar surface spacecraft:
- Shortly before sunset, temperatures at the surface are 390 K (116.85 °C, 242.33 °F) and we have full power generation from solar panels.
- Shortly after sunset, temperatures drop to approximately 100 K (-173.15 °C, -279.67 °F) and we will need to heat critical components to avoid damage from thermal stress etc.
- We estimate, roughly, that the thermal power we need is approximately 30 W throughout the lunar night.
- Lunar night is approximately 355 hours long.
- Shortly after sunrise, we regain full power generation from solar panels again.
- The lunar environment is a natural vacuum.
- Also note that the nighttime temperatures are cryogenic, enabling superconductivity.
- Low mass is preferred over low size.
We are primarily looking for off-the-shelf products. We do not have money to fund development of new products matching these requirements. --Anders Feder 22:03, 18 February 2009 (EST)
(30 W, how did you calculate that? I can calculate the excact amount of power and thermal energy we need to survive the lunar night.
Just give me the minimun temp. of the components, the power they need, the size and geometry of the box in wich these critical components (wich need to be heated) are placed in.)
