Nun, meines Wissens waren nur Shepards (und Ham's) Kapsel noch mit Heatsink gebaut, aber die Grissom-Kapsel schon die ablative Variante. ...
Hallo!
Habe mich mal wg. dem LB7-Hitzeschild umgesehen.
Colin Burgess schreibt auf Seite 21 in Liberty Bell 7: "While a beryllium heat shield would be used on capsules in the early booster test flights and the two suborbital missions of Shepard and Grissom, for orbital missions a new, ablative heat shield weighing far less was developed for the Mercury-Atlas flights that would follow."
In einem NASA-Dokument namens "Liberty Bell 7 Recovery Evaluation and Nondestructive Testing" / TM-1999-209824 heisst es: "We learned after these initial visits in subsequent talks with people who had been present during the recovery of the capsule that the TPS heat shield was not a phenolic TPS material. Instead, the first two flights had a beryllium heat shield for its TPS, which in the case of Liberty Bell 7 had completely corroded and was not recovered with the capsule."
Summa summarum: Grissoms Freiheitsglocke (... Liberty Bell) hatte keinen Ablativschild.
Diese NASA-Grafik ...
... soll die Unterschiede der Kapseln von Shepard (MR3) und Grissiom (MR4) zeigen.
