thruster

Elon just tweeted: "Issue with Dragon thruster pods.

All thruster burns now have to account for the structure's angular momentum.

Hyper-V had an impressive plasma thruster campaign, so I know they can deliver.

There's a trade off between how efficient a thruster is, and how much power it produces over a fixed amount of time.

A similar company is SeaBotix [0] they have a similar [1] thruster for sale but it uses a brushed motor.

* Pods 2 and 3 are pressure nominal and thrusters being tested; readings are optimistic; will be turned on shortly.

Q. Can you provide more details on Dragon Version 2?Musk: Significant upgrades, powerful side mounted thruster pods.

I'm imagining something like a thruster getting stuck on at a distance where it's far enough to build up some speed but close enough to have a decent chance of hitting.

3 of 4 thruster packs experienced the issue; they need 2 of 4 to open the solar panels and 3 of 4 to dock with the ISS. From what I understand they got all 4 working again using the "water hammer" effect to clear the blockage, but I'm not sure how accurate that is.

They might be referring to a new optimized thruster they couldn't test, or they might be saying they couldn't test in vacuum at all - it's never made clear and it's pretty damn important.

More expansion on the control mechanism for Hyperloop capsules, including attitude thruster or control moment gyros.

Recall that the ship itself is insulated & temperature-regulated, and therefore shields the emissions of the thruster.

Then they end on this note: "Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma.
