Bruce DePalma gyroscope experiment

Precesion.

@Xee2,

The gyroscope defys gravity. It leans over from it's tip over tendency, and looses it's perpendicular axis. It can't suspend itself leaning over on it's side while motionless. Bearingless magnet flywheels spin ten times faster then cheap gyroscopes, but precession can destabilize them unpredictably. I think it's just easier for them to lean over then levitate!

I finished the platform. The trellis for the hanging nylon axle guides is assembled from Tinker Toys. All I need are the nylon sleeves and the Reed switches.

The gyroscope should be spun while inside a air-tight jar, to prove it's not simply caused by the boundary layer of air moving.

I do not have a reference handy, but the gyroscope performs the same in a vacuum as it does in air (with the exception of drop experiments where air friction must be considered as with any falling object). However, there may be some effects on spinning balls that are similar to effects on spinning baseballs. In my test, there was no weight loss when the spinning gyroscope was held in place in the air, so it would be hard to argue that the presence of air was causing the weight loss.

Thanks for the link. This is a very interesting experiment. It shows that the spinning gyroscope falls slower than the box it is housed in. It also shows that the larger the precession angle is the slower the gyroscope falls. THIS IS A REAL ANTI-GRAVITY DEMONSTRATION.

Analysis

Gyroscope falls about 5 centimeters (about 2") less than box in 2 seconds. What is the difference in the acceleration of gravity on box and gyroscope?

for box

Db = distance box falls in 2 seconds = G * T^2 / 2 = 9.8 * 2^2 / 2 = about 19.6 meters (about 60 feet)
check:
acceleration of gravity on box = Gb = 2*Db / T^2 = 2*19.6 / 2^2 = 9.8 M/S^2

for gyroscope

Dg = distance gyroscope falls in 2 seconds = 19.6 - 0.05 meters = 19.55 meters

acceleratoion of gravity on gyroscope = Gg = 2*Dg / T^2 = 2*19.55 / 2^2 = 9.775 M/S^2

therefore difference in gravity for box and gyroscope is


9.8 - 9.775 = 0.0250 M/S^2

0.0250/9.8 * 100 = 0.255 %

about 2.5 parts per thousand

@ Allen Burgess

I am concerned that you may not see any loss of weight because the spinner is not free to precess. But, we shall see when you do your experiment. I am looking forward to your results.

Precesion.

Xee2,

The 1/2" neo sphere ran around the inside of the cup. I wonder if that kind of eccentric rotation is revolution? I'll try a few things. I found the old spool bifilar coil I set my speed records with.

[Allen Burgess]

Depalma experiment.

I need to rebuild the old PVC coupling with the nylon axle and ceramic bearings. The bearingless spinner is too eratic for very high speed running. The entire case can be placed sideways, so the axis of spinner rotation is horizontal and the case and power coil are allowed to precess on a pivoting stud on the scale balance. Wireless pancake reciever and power coils can be mounted on and overhead to avoid twisted power wires.

The amp meter showed zero input spinning a neo at 5k. What I noticed with the reed switch in series with the hi-voltage bifilar and precision ceramic bearings was the astonishing surge above the reed switch limit. The switch must be shorted out when it takes off under it's own steam, perhaps in resonance with the battery. I coined the term "Lenz Propulsion" to describe this coil shorted burst of acceleration. The 'Magneto Generating Effect" of the powerfull neo spinner builds such a strong flux field in the power coil, input can no longer force it's way in, while the spinner is racing ahead full speed!

I tried disconnecting the battery, and it died; Capacitor exploded. No self runner. However, this approach should satisfy Xee2's cautioning about the essential nature of precession.

I don't know how these kind of bearings are going to hold up when placed on end. I plan to search for something better. My math tells me a that a gyro spinning 100x's the speed of DePalma's, should generate 100x's the weightlessness! Precession increases as the gyro slows, and weightlessness increases directly in proportion. Powering the spinner down and sustaining maximum precessional levitation should be achievable with this setup.

The case and spinner might begin to pick up alot of speed if the spinner axis was forceably tilted to generate the precession. Adding a remote servo and tiny stepper motor would permit the case to roll. Coupled with the power adjustment, these controls should make it possible to maximize lift. The tough PVC coupling is strong enough to absorb any problem with the spinner. I attached a picture below.

The Hannebu II may have controlled the precession of the large central magnet sphere by swirling the driver satellites around in a cresting wave pattern.

I repeated my original experiment using a video camera instead of a still camera. I feel this better documents what is happening.

Spinning Gyroscope Weightloss.

So, the upright bearingless spinner should grow lighter. There's a youtube video of a horizontal spinner gaining weight I can't find! I think I'll simply mount one of my Bedini Spiral Bifilars and large spinning neo spheres on the scale balance, and check for weight loss.

"In the London Sunday Telegraph of 21 Sept. 1997, Robert Matthews reports that "a team of Japanese scientists have spun up a gyroscope to 18000 rpm and dropped it through a distance of 63 inches in vacuo. The time taken to fall this distance was 1/25000 sec. longer than when the gyroscope was not spinning, corresponding to a weight reduction of 1 part in 7000. The effect only occurred when the gyroscope was spinning anticlockwise. The fall was timed using laser beams. The team say that this is in line with earlier findings of theirs published in 1989."

quote from >> FALLING GYROSCOPE EXPERIMENT

In my experiment the gyroscope was spinning anti-clockwise when viewed from the top.

[Allen Burgess]

Experiment.

I narrowed my problem down to a dead potentiometer and fired a new Daftman Bedini SSG up with a replacement. The experiment's all set up and ready to video tape. I clocked the 1" neo sphere at over 50k inside a 1" PVC coupling (Pirate Twinbeard's) powered by the bifilar Spiral. The rapidly rotating neo sphere appears to be visably weightless at high speed inside the coupling. Why? We're looking for reasons. I should have a "Weightless Test" video uploaded by tomorrow.
