Static fire test of Falcon 9 at Vandenberg AFB complete—launch of 10 @IridiumComm NEXT satellites slated for Sunday, June 25.
Podobno w tym locie mają zadebiutować tytanowe lotki. Na razie jednak nie ma żadnych zdjęć żeby to potwierdzić.
EM: They will, but the hydraulic system is closed loop, so no fluid lost. They do need more power & energy, but rocket has plenty of that.DN: Is this the first closed loop version? I thought some of the early attempts ran out of hydraulic fluid due to it being openEM: We used to have a (lame) open loop hydraulic system, but that was upgraded to closed about 2 years ago
Myslałem, że do kontroli lotek nadal używają otwartego układu hydraulicznego, a tutaj okazuje się, że to już dawno nieprawda:CytujEM: They will, but the hydraulic system is closed loop, so no fluid lost.

Elon MuskKonto zweryfikowane @elonmusk 8 godz.8 godzin temuFlying with larger & significantly upgraded hypersonic grid fins. Single piece cast & cut titanium. Can take reentry heat with no shielding.
Q: Are they heavier than the originals?Musk: Slightly heavier than shielded aluminum, but more control authority and can be reused indefinitely with no touch upsQ: Did the heating of the previous fins show noticeable issues with steering?Musk: No, but shielding got fragged every flight. More control authority is for Falcon Heavy, but also enables Falcon 9 to land in heavier winds.
