![]() Let's say we're making a small grid and use small ion thrusters.ġ small ion thruster is 14 kN (kilonewton) or 14000 newtons. If you go to space engineers engineer wiki, you can see this article: To make this happen, you need to produce F = m * a = 10000kg * 10 m/s^2 = 100000 newtons. 10 m/s gain in velocity per second is acceleration of 10 (m/s^2 or m/(s*s), meters per second squared) Using this formula, you can determine how much force you need to make ship reach target speed.įor example, in zero g, you want to have 10000kg mass ("m") go from 0 to 10 m/s in a second. ![]() In general, in space engineers things are using newton laws.įorce equals mass multiplied by acceleration. turns out my design is grossly over weight. as I didn't know if it was modelled but the hints were there. I had not figure on the thrust to weight ration. Enjoy zero g.Īlso be ready to scream profanities on the way down afterwards, and it might be a good idea to set a GPS marker for your base before you leave for orbit. Then load the ship with hydrogen, blast off, disable dampeners, and keep pressing space to maintain your speed at high value (>= 90 m/s or so. Then keep adding thrusters until total lift generated by downward pointing thrusters is larger than weigh of your ship. Long story short, to go into orbit, make any ship with truckload of hydrogen, attach a cockpit to it, sit on it, and check how much this thing weighs at bottom right. You can for example, disable dampeners (Z) fly up, and keep blasting just enough to keep your speed above zero, or ideally somewhere above 90 m/s. It might be a good idea to keep in mind that it is impossible to fly faster than 100 m/s in unmodded game, and gravity drops off with height, so you don't necessarily need to keep blasting thrusters at maximum force all the way up. Now that lift calculation is out of the picture, to leave gravity well, you need enough fuel to keep countering gravity until you're in zero-gl. Technically this is not precise, because you need to divide force by gravity, meaning 340 kN will actually be able to support 34693 kg of mass in earth gravity and not 34000, but it is a decent rule of the thumb, unless you really want to visit alien planet. For example, one atmospheric small thruster on a small ship can support roughly 34 000 kg of mass on earth-like gravity. go to space engineer wiki and look for FORCE engine provides.įor example, small atmospheric thruster on a small ship produces 340 kN (kilonewton of force).įor simplicity, you can drop one zero and it will be roughly how much this ship can weigh without losing ability to hover in kilograms. Hydrogen engines devour hydrogen almost instantly, and if you're using small fuel tank it will be gone once you blink. You need sufficient LIFT, and enough FUEL.

The only difference I can see from my set up and splitsie's is that I have no reactor as I have not found any uranium.Ĭan anyone explain how to get off a planet? Thanks in advance. I have tried to make the transition at lower altitudes but does not help. But I am up to 4 large thrusters in a small grid and it always does the same thing. I thought the problem might me that I need more thrust. ![]() Then after that, no matter what I do, I am only going down. WIth this combinations, I get to about 5km when the speed starts to reduce, I switch off the atmosphere engines and tilt 90 degrees (just like in splitsie's video) engaging the main thrusters and it goes fast. But the best one so far multiple hydrogen engines 4 atmosphere engines to aid on the take off. Built different ships with different configurations. However, whilst playing survival mode, I have not been able to get off the planet. ![]() Learning how to make the different blocks is a blast.
