Kerbal Space Program: Fuel Burner Design (untested)

This design is a Launchpad design meant for testing out fuel ducting on fuel pods and ships as well.  Here is a view of the top down view of the fuel burner:

(The orange circles represent engines)
The center is a fuel tank
The squiggly lines are my rushed version of fuel ducts

The one thing that I had difficulty showing on the image above is that all of the engines are facing away from the center fuel tank.  This means that the overall thrust is zero as all of the engines will be providing thrust towards the center of mass.

What is great about that is that more than one set of 8 engines can be attached.  Fit as many sets of those engines as possible so that the engines will burn through the fuel that much quicker.

Last thing to do is to make sure there is a fuel duct from your ship's final stage of fuel and attach that to the center fuel tank of this fuel burner module above.  This will show you a quicker version of your fuel consumption and how the fuel is being consumed over time.



It is unknown at the time of this design whether this will actually work.  Theoretically the design is sound, but I do not know if the center fuel tank will be able to handle the thrust from the engines.
  When this has been actually tested, I will need to update this post with the results.
