I need help with the style conventions of Lunarpedia. I am out of practice in contributing for Lunarpedia and if someone could tell me what is needed to meet the ordinary style expected, I would appreciate that.
For the recycling of rocket exhaust from a rocket launched through a tube there would be some difficulty is testing the concept on Earth. To prevent damage to the wall of the tube at the launch of the rocket, the rocket could be launched from a mobile launch platform accelerated in much the same way that fighter aircraft are accelerated. This could give the rocket a velocity of 67 meters per second at the time of launch thus spreading the erosive effect of the exhaust out over a larger area of the tube wall. This would also provide the ullage thrust necessary for the bubble in the fuel tank to be toward the front of the rocket and the fuel to be next to the fuel pump inlet. Also it provides the first 4 percent of mission delta v. However this does not work in reverse with the rocket decelerating to a stop and landing in a tube as would be necessary if one were performing a test on Earth and wanted to preserve the test rocket for another run.
The use of a larger tube for the tube landing area in the model test with T intersecting tube sections allowing the exhaust to dissipate into a larger area might serve the purpose of a model test or the purpose of an operational variant for which it is necessary to eject orbit bound cargo immediately after the rocket exits the acceleration tube with the rocket proceeding to a deceleration tube.
