Simple method for testing the Fluid Space Drive principle (adequate for testing other propulsion proposals)
For a quick read you can skip the yellow (not indispensable) and the blue (calculations) text boxes.
††††††††††† The objective of this experiment is to determine if a propeller enclosed in an airtight box can exert a force that pushes (propels) the box from the inside, and the magnitude of that force.
††††††††††† The method to be used is hanging the airtight box from the celling by four cords, comparing the position of the box at rest (propellers not activated) with the position of the box when propellers are activated (displacement) (Fig 1).
††††††††††††††††††††††††††††††††††† Fig 1
††††††††††††††††††††††††††††††††††††††††† Fig 2
For the experiment you will need:
An airtight box to put the mechanism to be tested.
A motorized propeller(s) on a pedestal with R/C unit to turn propellers on/off (optional)
Two lightweight supporting beams (Fig 2)
Description of the airtight test box.
Although we have seen a simple cardboard test box can be used (see here) we recommend the following design for consistent results that can be compared with ours (if you desire)
The box has the following dimensions (Fig 2)
Height 1 meter.
Length 1.4 meters.
Width 1 meter.
Plus rounded rear and forward end with a 0.5 meter radius
Description of the motorized propeller(s) on a pedestal assembly.
††††††††††††††††† Fig 4
Fig 4 illustrates a pedestal attached to a base, the pedestal has two Lego motors and propellers (Fig 5), one of the propellers is counter rotating.
Also illustrated is a toy R/C car used to turn the propellers on/off remotely (you can use Arduinos or other system)
The propellers can be constructed using an old PC power supply fan (1) with a Lego wheel (2) glued in it (Fig 5).
Cardboard cut outs (3) were attached to the power supply fan to increase size (Fig 5).
The resulting propeller was attached to a Lego Motor and installed on a pedestal inside the box (Fig 6).
So what can we expect? (Results)
Illustrated in Fig 7 is the position of the elements when the airtight box is at rest (propellers turned off), a pointer attached to the box is positioned at 0, when the propellers are turned on, if there is a force pushing inside the box the pointer will move to a position of 2 or 3 mm and stay in that position for as long as the propellers are turning, when power is switched off the box will swing to -2 or -3 mm and oscillate until it comes to a full stop (at rest)
28.4 millinewtons is equivalent the power generated by todayís low end Ion thruster, they presently range from 28 to 250 millinewtons.
But we must remember that Ion thrusters are a mature technology, by that I mean that thousands and thousands of research and engineering hours have been invested, as has been billions of dollars.
The Fluid Space Drive is optioning similar results using only a few dollars of materials.
Also as the Fluid Space Drive does NOT expel any type of mass (no even ions) it can continue acceleration for as long as a power source is available propelling spacecraft further an faster than ever before.
