1. Summary of Results

The results show that perhaps the previous results may be pointing in the correct direction, a precessing gyro produces more force then a non-precessing gyro. However, until channel two data can be collected, the results are incomplete.

It seems reasonable at this point to suggest that a precessing gyro may affect the centrifugal force.

2. Introduction

These test results where done with 12" diameter gyros with a .075" thick webbing or spoke and can be seen compared to the 10" gyro in figure one (the two are compared only for show, one set is removed for testing). Note that the 12" gyros have two bearings each to improve stability.

See Initial Results for a description of the variable types.

Note: No video was taken of these test runs because the motion is the same as in the previous test results and there is not enough space on the web server.

3. Baseline Results

These results correspond to step 3 in the description and are run with the following static variables:

Gyro rotation speed: 2000RPM (if spinning)
Gyro diameter: 12"
Angle: Horizontal

Non Spinning Horizontally Held Gyros

~10lbs on Channel Two

Note: This was chosen because when channel two measures that force, a 2000RPM gyro is off it's rest and can provide an easy baseline.

4. Primary Results

The primary results consist of altering one variable at a time and each time, two separate measurements are taken.

For all the primary results, the following static variables apply:

Gyro rotation speed: 2000RPM
Gyro diameter: 12"
Angle: Horizontal
Main platform rotation speed is such that when channel one is precessing, 10lbs is the target for channel two (which is not spinning) and when channel two is precessing (as in G_2_0_05), the target for channel one is 4lbs. These targets are per the 10lbs baseline.
In the screen shots below, the pale blue, green, and red are the primary results, and the yellow (channel two), purple (channel one) and white are the baseline results measured in step 3 above.

Gyro Variable, Channel One Gyro 2000RPM - G_1_0_06

Raw Data: "C0 - G_1_0_06.txt" (Contained in "Raw Data for Gyro Variable.zip")

Gyro Variable, Channel Two Gyro 2000RPM - G_2_0_05

Note: These results are invalid because the gyro is not properly balanced and generated too much vibration.

5. Analysis

As shown in figure G_1_0_05 and G_1_0_06 when the second gyro, blue and not spinning, is generating the same centrifugal force as the baseline (yellow), the gyro under test (green) is producing more centrifugal force then the baseline (purple).

However, until the second gyro is fixed, both for balance and with a matching load cell, the results are incomplete.
