Designing space vehicle shields for meteoroid protection: A new analysis

Method for calculating the parameters of partially coherent radiation in a turbulent medium with regular refraction

“…Studies made on highvelocity impacts (Pailer and Griin 1980. Igenbergs et a1 1982, Mandeville 1979, Swift et a1 1982, McDonnell et al 1986 allow the marginal penetration of thin films to be accurately defined, providing a calibration point midway between the penetration limits of the IPM-P 2.5 pm aluminium penetration foil and the Giotto front shield. …”

Debris Cloud Material Characterization for Hypervelocity Impacts of Single- and Multi-Material Projectiles on Thin Target Plates

“…Current semi-analytical lethality assessment models usually fall into one of two broad groups: discrete particle models [3][4][5][6][7][8][9][10][11][12]17,18] and expanding shell models [19][20][21][22][23]. Discrete particle models typically account for only solid fragments [3][4][5][6][7][8]17,18], or track only a small number of discrete fragments [9][10][11][12] in the debris cloud created by a high speed impact.…”

“…Although a substantial amount of algebra is required to derive equations 13 (17)(18)(19)(20)(21)(22)(23), the manipulations involved in deriving a closed-form expression for (P 2 )i Wan be reduced significantly if equation (15) is re-written in the following form:…”
