MANNED SPACECRAFT CREW SURVIVABILITY (MSCSURV) CODE

Description:

MSCSurv is will find the conditional probability of losing one or more crew members, given the penetration of orbital debris through pressure wall rupture (explosive decompression), fragment-induced injury, and "slow" depressurization. MSCSurv uses a Monte Carlo style subroutine to simulate the penetration of orbital debris of various sizes, velocities, and angles of approach and will query the user on a variety of assumptions that can alter the probability of crew loss (i.e., crew sleep position, hole size model, critical crack length prior to pressure wall rupture, etc.). Although MSCSurv Version 1.0 is currently a very specific application for use on Space Station modules, the model is being expanded to compatibility with other spacecraft BUMPER geometry models.
