IS THIS A REACTIONLESS DRIVE OR A PERPETUAL MOTION MACHINE?

@nix85:


The device in your drawing - operating as a subsystem - will produce vertical acceleration, provided the subsystem is moved side to side, in synch with its operation,  with two steps in each direction.

it is not clear what you mean by two step in each direction and in synch with its operation.

there is no need for two steps in each direction nor synching except syncthing
of two counterrotating arms but that is sure not what you meant.

keep in mind, one guy built my wider previously shown design
and it did not work. it did jump in the air but bounced back down.

(shown below)

so i narrowed the walls to reduce the y reaction.

when there is just one arm, back reaction of the spring on the side wall
is trying to rotate the frame which obviously acts to prevent forward
acceleration.

i believe if he built two so they operate in counterrotation, backtorque
would be canceled and pure upward thrust would result

[nix85]

there is no need to pull the device to the left or right.
besides what would you pull it against, the whole
point is that it is reactionless.

pull on the side wall produces back torque
which wants to rotate the frame
two arms in counterrotation cancel it

that's all

[nix85]

don't you read what i write. i said it bounced back cause of counter torque.
if counter torque is canceled it should produce pure linear thrust.

linear actuator? i'll assume you mean side walls. no, centrifugal force
is felt at the axis of rotation, of course.

"just attach the springs directly to the base, on each side" is an old abandoned idea
of mine. there is no benefit from it, you get the same counter rotation of the frame
it is essentially the same as side walls.

when frame is narrow then also back torque is less

but best combination is pulling against side walls with two arms
in counterrotation, so that back torque is canceled.

"Conservation of Momentum will cause it to slow down" no, friction will
and there is no need to add torque, this is a simple demonstration device

i thought of that and there are various ways to add torque to such system
including linear arm on offset rotor, electromagnets etc.

one good spring pull has enough energy to lift the device few meters in the air
maybe more
