Creating a new THS space drive

[mindbound]

That link doesn't have enough information

Yes, perhaps the specific example I picked wasn't ideal.

That being said, many thanks for the worked example! I think I'll be able to continue from here.

Edit: A few questions here for the-red-scare.

Example: I want my fusion rocket to get 0.005 G from an engine massing 1/20 of loaded mass. I multiply 0.1 by 4/0.05 to get 0.4. The THS thrust is therefore 0.4 tons.

What is the 0.1 in the calculation, how does the 0.005 factor in there, and how do you get 0.4 from 0.1*4/0.05? I assume I have misunderstood the formula there.

Thrust is based on the thrust-to-weight ratio of the drive. Atomic Rockets generally provides this. You just multiple the T/W by 4 and you’re done.

Do I understand it correctly that by multiplying the TWR by 4 (presumably the mass per space of drive?) I'll get the THS' thrust per space of drive figure?

Thank you in advance!
