Infobox Performance

[edit]

What is the best way to label the items in the Infobox so that it is clear that the thrust of 16,400 lbf is per individual thruster, but that the propellant capacity of 3,060 lbs is total for all 8 thrusters? -- ToE 14:37, 11 May 2015 (UTC)[reply]

Propellant capacity is a stage/spacecraft characteristic. The most related engine characteristic is design life or burn time.Baldusi (talk) 00:26, 30 June 2015 (UTC)[reply]

The Specific Impulse is incorrect or at least not supported by the reference. The number 235 given for Isp does not exist in the document. I believe it may have been drawn from the mass flow rate of 31kg/s but it was computed incorrectly. Super Draco is 73 kN (73 kN / 10 /31) = 235.6 however this is incorrect because the 31m/s is based on the downrated 68.17 kN. Correct specific impulse based on the reference should be 240s (68.17 kN / 9.8 m/s2 / 31kg/s = 240s). ^[1] Namechamps (talk) 16:10, 17 September 2015 (UTC)[reply]

Perhaps "interval" should be "internal"? 94.30.84.71 (talk) 22:32, 26 November 2015 (UTC)[reply]

This article says "SuperDracos will be used on both the Dragon V2 crew- and cargo-transporting space capsule". But the Dragon 2 article lists the SuperDraco escape system as being installed only on the crewed variant. So it seems that one of the two articles isn't correct. -- Finlay McWalter··–·Talk 14:01, 2 December 2018 (UTC)[reply]

On April 20, 2019, the SpaceX Crew Dragon capsule used on DM-1 was destroyed during a test of the SuperDraco engines at Landing Zone 1 https://arstechnica.com/science/2019/04/heres-what-we-know-and-what-we-dont-about-the-crew-dragon-accident/ — Preceding unsigned comment added by 24.51.153.90 (talk) 18:51, 28 April 2019 (UTC)[reply]

Second sentence "A redundant array". Redundant means "no longer needed or useful; superfluous.". As it's clearly not that, what could the contributor be referring to? --Dave F63 (talk) 18:22, 16 January 2021 (UTC)[reply]

Redundant array is a common term used for a group of objects that indicates that they can continue to perform their function and recover, without any loss of ability to do the job, in the event of one or more of their members failing. It's the same as in RAID (Redundant Array of Independent Disks). Canterbury Tail talk 12:54, 12 February 2021 (UTC)[reply]
