Launching rockets 2
In the previous post I talked about the mathematical model. Is that viable?
No.
Parts:
Vacuum: To produce the vacuum needed a turbomolecular pump, chosen by producing high vacuum (0.00133 Pascal) and speed of work (3500 L / s) is used.
Column pitcher: Where the vacuum occurs and the load is.
Charge: To prevent excessive friction and wear against the walls of the pitcher column, the optimal way to load a sphere.
Top cover: When the air (almost empty) in column pitcher is contracted by the ascent of the rocket, this produces a force to the upper end. The superior being not mechanically closed, close opens when the pressure equals the atmospheric column, releasing the rocket.
1- Air
The fluid pressure in the column is atmospheric air.
2 Water:
Non-gaseous fluids exhibit advantage produce higher pressure and thus improved acceleration rocket.
There is still a major drawback: great friction present to the column and thus the potential energy throughout the column having lost as heat.
You have to get that water flow can reach escape velocity, and that is only possible through the Leiderfrost effect. The water to be on a surface with significantly higher boiling point than this temperature, produces a “cushion” of air which drastically reduces friction.
Quick Results:
From the theoretical models I have seen the project could accelerate a rocket to escape velocity (12 km/s). Despite the technical simplicity of the air pressure column, this was not able to accelerate enough; Where a column of 1000 meters high and 113 kPa (atmospheric pressure at -1000 meters) the rocket only get a maximum speed of 1.3 km / sec; Not enough to escape velocity.
Quite the contrary with pressure column using water from a dam as the Leidenfrost effect reduced by friction (column pitcher warming up to over 100 degrees Celsius), was able to accelerate a load of 1000 kg to 13.5 Km / s. Thus achieving escape velocity of 12km / s. This is possible thanks to the immense pressure of the water 56 million Pa to 1000 meters deep (pure water). We also noticed that the same water could be used to power the pump turbomelcular to produce a vacuum.
