Drop tower layout is shown featuring a non-vacuum dual capsule design at a low cost.
- •
Drop capsules were aerodynamically optimized to achieve quality of better than 4576516305811&_mathId=si0001.gif&_user=111111111&_pii=S0094576516305811&_rdoc=1&_issn=00945765&md5=79adadb1aea7ed57ace2c361db108a74" title="Click to view the MathML source">10−5 g.
- •
Molten rod release mechanism allows disturbances to be damped within less than 0.1 s.
- •
Performance of deceleration device with polystyrene beads was tested in small scale.
- •
Deceleration method shows promising performance although smaller beads are required.
