IanWPGCA Posted September 11, 2020 Share Posted September 11, 2020 Can someone confirm my math on engine power required to liftoff the ground? I will share the google sheets link. Looks alright but I am no math wise kid need someone to basically proofread it but for math. ( Mass To Engine Power Converter ) https://docs.google.com/spreadsheets/d/194m61B65xFCr5lNP12EF5XK4tbl2qOLDum2xR0cUzug/edit?usp=sharing I wanted to make it easier for me to calculate how much thrust I would need for liftoff / forward momentum without guessing, I hope this correct I did alot of Google raid researching.

IanWPGCA Posted September 11, 2020 Author Share Posted September 11, 2020 Oh man my numbers are way off, I suck at research lol Link to comment Share on other sites More sharing options...
CodeGlitch0 Posted September 11, 2020 Share Posted September 11, 2020 At 1g, it takes about 9800 N to cancel out (not lift!) 1000kg of mass. Link to comment Share on other sites More sharing options...
CodeGlitch0 Posted September 12, 2020 Share Posted September 12, 2020 Previous reply was a bit terse and could use additional explanation... 9800N will cancel the effect of gravity if aligned in opposing direction to gravity. It will do nothing else. If you want to move anything (additional acceleration), you need multiples of that. How much depends on what you are tryong to achieve. 4X (4g) is probably about minimum, 10g gives most flexibility. Link to comment Share on other sites More sharing options...
Megaddd Posted September 12, 2020 Share Posted September 12, 2020 Oh that's easy. Just take your mass in tons, multiply that by 20, and you get the amount of thrust/lift in kN you want in any direction as a minimum baseline to make a great to control ship.

Tenryuta Posted September 16, 2020 Share Posted September 16, 2020 dont forget the 9001 adjustors to reduce wobble by half Link to comment Share on other sites More sharing options...
pogopvp Posted September 24, 2020 Share Posted September 24, 2020 Here's the full math 1g (gravity) = 9.81 m/s2 (acceleration) Force = mass * acceleration if your ship weighs 1000kg that means its gravitational Force (F) on a planet with 1g = . F=m*a F=1000 * 9.81 F= 9810 Newton If you have 9810 of force exactly opposed (straight into the sky), you would neither fall or climb. you need your acceleration (a) to be more than that 9.81 which means either "F" has to go up, or "m" has to come down. On planets with a gravity less than 1g, just use this formula : Force (N) = mass (kg) * gravity (g) * 9.81 Link to comment Share on other sites More sharing options...
Tenryuta Posted October 4, 2020 Share Posted October 4, 2020 use this, that one above is 'access denied' to me(is it set to private?), the covers all the zany numbers the build helper doesnt. https://docs.google.com/spreadsheets/d/1RpzAyLLdENR88TYp3sk535fY9x4PBxKy5CbGBSGjQc4/edit#gid=723465479 On 9/24/2020 at 4:12 AM, pogopvp said: Here's the full math 1g (gravity) = 9.81 m/s2 (acceleration) Force = mass * acceleration if your ship weighs 1000kg that means its gravitational Force (F) on a planet with 1g = .
