[Spaceships] Calculating Stall Speed?

vicky_molokh · 04-20-2012, 06:15 AM

Greetings, all!

It's all in the title. How do I calculate stall speeds for vehicles built with Spaceships / Alternate GURPS Pyramid?

Thanks in advance!

Spaceships seems to assume that craft can be fitted with vectored thrust at no added expense, meaning that if you have thrust equal to local gravity you can fly with no stall speed. For slower (or non-vectored) craft however, it seems to be below the system's resolution. I suppose you could fiddle around with VE2 to make a winged craft with equal thrust, mass and speed to a Spaceship design, and see what it's stall speed turns out as. From there you might be able to establish a rule of thumb for estimating stall speed.
