MAE 306 Fall 2008 HW 10 Due 5:00 PM, Thursday April 24, 2008 Space Environment Use the information in SMAD Ch. 8 and Ch. 21 to approximate the following for your spacecraft: 1. (2 points) Fluence of atomic oxygen during the spacecraft’s lifetime (may be zero; but explain if so) 2. (2 points) Flux (annual impacts per area, see Ch. 21) of meteoroid and orbital debris at Solar Max (may be zero; but explain if so). 3. (2 points) Assuming your spacecraft is in a 30 deg. inclined earth orbit at an altitude of about 3500 km altitude, with 0.508 cm of aluminum shielding around its electronics, what is the total radiation dose (in rads) received in two years?

Unformatted text preview: 4. (2 points) What is the lower and upper bound of the overall weight required for your spacecraft to achieve a desired hardness level of 1×10-2 cal/cm 2 ? 5. (2 points) Approximately what is the total-dose capability of Mylar? Power 1. (2 points) Write two paragraphs describing and justifying the implementation of power technology on your spacecraft. Use formulas from SMAD to size solar cells, nuclear power, or whatever technology you propose. Describe your chosen energy-storage technique as well as the power-generation technique....
