Yes OS: Windows 10 | CPU: Intel Core i7 9750H | GPU: NVIDIA GeForce GTX 1650 | RAM: 16 GB I built a craft with multiple types of engines on certain stage. After solid boosters decoupling I had stage with 1 Skipper and 4 Swivel, and before this stage burn out dV fluctuated with very wide spread, like it tried to show 2 different configurations. I attached video and craft file How to try to reproduce this Build craft which has different types of engines on some stage. Better if it will be engines differing in thrust not much and not slightly Launch craft and try to get these fluctuations I have assumptions that game tried to calculate dV with one specific impulse, but those engines had different specific impulse and game swiched between them Here is formula for Isp for multiple engines: https://wiki.kerbalspaceprogram.com/wiki/Specific_impulse Included Attachments: dVjumps.mp4 MunExpSystemMk2.json Edited February 3, 2024 by Spicat Link to comment Share on other sites More sharing options...

Yes OS: Windows 10 | CPU: Intel Core i7 9750H | GPU: NVIDIA GeForce GTX 1650 | RAM: 16 GB Merge with this please: I suspect that bud is connected not so much with different engines as with different specific impulses on the engines. I built plane with 3 J-404 "Panther". The one in the center was in afterburner mode, others 2 were in cruise mode. And I had the same situation when dV showed 2 different values alternately as you can see in video (from 46 000 m/s to 44 000 m/s). I attached craft file and video Included Attachments: dVjumpsduringatmoflight.mp4 FlyerB.json Link to comment Share on other sites More sharing options...
