##### The Orbital Mass Accelerator Engine Theory
« on: 04/07/2018 03:04 am »
Two objects equal in weight traveling on the same orbital path in the opposite directions propel each other to intersect on the opposite side of the Earth in alignment to propel again gaining altitude in orbit?

Compared to most normal artificial satellites chemical propellant is saved  but still used adjust altitude or coarse from orbital perturbation but negated by alternating magnetic fields OMA by angle?

Does an orbit exist in which orbital perturbation effects both parts in favor alignment?

I understand that in a lower orbit, when you increase speed you gain altitude - and to maintain a higher orbit you must then decrease the speed less than what the lower orbit speed was.

Can the velocity be increased, then decreased on the first pass or by 2 rings one that pushes and the other pulls while inside the OMA would the passenger it would feel a quick-lifting jerk?

Alternative or in conjunction: After the acceleration on the 1st pass the object and OMA then meet on the opposite side of the Earth on the 2nd pass to decelerate to reestablish orbit at a higher altitude?

Could they at the least maintain orbit?

Would there be any practical use of this device like kicking other nonfunctional satellites out of orbit?

Your understanding of raising you orbit is a little backwards. When you raise your altitude by increasing speed, your speed will start falling immediately until you reach the high point of your new orbit. At that point, you'll be going too slow to maintain a circular orbit at that altitude, so you'll start heading lower again and be in an ellipse until something disturbs it. All orbits are a little elliptical. There's no such thing as a perfect, circular orbit. If you tried to make one, the tiniest factor would instantly make it elliptical to some degree. To make a (mostly) circular orbit at the high point, you need to raise your speed, not decrease it.
As for your scheme of two object reacting off each other to gain orbital velocity, I've never heard of it, but can't think of any basic reason it wouldn't work. If they were equal mass, they should keep meeting up every half orbit at apogee and perigee. At 30,000 mph relative velocity, you probably won't be using a grappling hook and winch, but that's just details.
If you ever do send something up that can grab debris, the amount and direction it will change your vehicle's path will be part of the equation. If you do it right, you could use the velocity change caused by whatever you grab to send you to another target. Or toss the debris into a path that will re-enter a lot sooner and use the velocity change caused by that ejection to alter your craft's path.

Accelerating the craft by decellerating the debris so it reenters faster is a novel approach that we haven't heard a lot about yet.

The altitude is increased not by angle but by speed horizontally and then stabilized.  Coarse adjustment is done by angled acceleration. This process could be repeated to gain altitude from low to high orbit but how high of an orbit? Could the orbit include the moon? This could be used to transfer cargo from low orbit to the moon. Not saying thrusters couldn't be used only that OMA would reduce the need of them. With laser tracking and a wide birth at least cube satellites could be kept in orbit with solar power. I would not use the OMA to decelerate non functional satellites alone. To maintain OMA orbit equal in weight in satellites will both be pushed to escape velocity and slowed to fall to Earth. The OMA could intercept objects to push at an angle not only on a horizontal plain furthering chemical propulsion savings. This is all in theory of coarse and invite any critical thought.
