    Can Mass Distribution and Spring Constants Keep a Hovering Platform Stable?

    Hi there. I tried your plan Dave but it still settles at an angle if the centre of gravity is not in the centre of the car. I have been trying to make a system work that adjusts the thrusters just based on their height from the ground but it is quite dodgy so far. I think the answer might have...

    Can Mass Distribution and Spring Constants Keep a Hovering Platform Stable?

    Thanks for that suggestion Dave. I didn't see it yesterday when i replied to russ so hopefully i will get a chance to try it out tonight when i get home from work. Sounds good in theory.

    Can Mass Distribution and Spring Constants Keep a Hovering Platform Stable?

    OK I was a bit to absorbed in my own little world there. Will try to explain further. The reason I used a spring/damper formula is that I am trying to build a realistic hover racing sim. The hover cars are actually rectangular and have a thruster at each corner. Each thruster projects a line...

    Can Mass Distribution and Spring Constants Keep a Hovering Platform Stable?

    Hi there. I have got very good help from this forum in the past and I have yet another question. Take a square platform with a thruster at each corner. Put a weight in the centre of it. Now, with the weight in the centre the platform is stable but as you move the weight to one side the...

    What are the key factors in calculating the thrust of a turbofan engine?

    Hi there. Many thanks for all the info chaps. Looks like i have some more revision to do. Will post back when i get it running. Again, thanks for the help.

    What are the key factors in calculating the thrust of a turbofan engine?

    Hi there. I am trying to work out a basic turbo fan model for a simulator I am working on and I have got a bit lost. I’m ok with ridged body physics but this is a bit outside of what I know. Here’s what I have so far given that the engine is running: So, the compressor sucks air in at the...

    Thrust & Pressure: Physics Simulation for Hovercrafts

    Hi there. Thanks for you input chaps. Very helpful indeed. I will try some of this out tonight now that i have some idea of what should be going on. Thanks again.:0)

    Thrust & Pressure: Physics Simulation for Hovercrafts

    Hi there. I am trying to create a realistic physics simulation for testing thrust based hovering vehicle designs and i am stuck. I understand basic physics like moment of inertia and forces and the like but thrust is something i am having trouble with. Currently if i place a vertical...
