Update #41

Building a railroad to orbit for you!

HyperV Technologies Corp.'s first Kickstarter project, the E3P-1 thruster, addressed reducing the cost, and increasing the efficiency and the utility of in-orbit spacecraft propulsion. Our next Kickstarter project will also address reducing cost and increasing both the utility and efficiency of space transportation. However, this next project will focus on a different segment of what is potentially a revolutionary new space transportation infrastructure. Like the early railroads that opened many of the world’s frontiers, our next project could transform access to space by dramatically reducing the cost and increasing launch opportunities.

We are very excited to make this first announcement to all of you, our backers, that HyperV Technologies Corp. has agreed to take over the development of a novel mechanical mass launch device called the Slingatron. Our plan is to incrementally grow the capabilities of this transformative space launch technology, with the goal of providing low cost, high volume commercial space launch services.

With the majority of the launch equipment remaining on the ground, the Slingatron is essentially fully reusable, highly reliable, and, like a train, can provide regularly scheduled low cost transportation.

So what the heck is a Slingatron?

The Slingatron is an earth based mechanical hypervelocity mass accelerator, which theoretically can be built large enough to launch a steady stream of payloads into orbit and beyond. These payloads could range in size from tiny cubesat class satellites to multi-ton payload containers.

To date three Slingatron demonstrator machines have been built. Here is a video of the one-meter diameter Mark II machine in operation: https://www.youtube.com/watch?v=qZi2vQ86Q0A

The Slingatron launch track is a spiral tube mounted on top of a modular high RPM gyrating platform. A video of the Slingatron basic function can be seen here: https://www.youtube.com/watch?v=HHnQnb9mmco During launch, the payload, or launch, module is released into the track at the center of the spiral. Once placed onto the gyrating track, the launch module becomes phase-locked with the hula-hoop-like gyration of the platform. The strong gyrating centripetal force of the track causes the payload module to rapidly accelerate. The payload module effectively thinks it is constantly accelerating down an incline under a high gravity. This rapid acceleration is then tremendously amplified as the launch module is forced to stay in synchronization with the powerful gyration force as it travels farther out into the ever-widening spiral track. The unique mechanical action of the Slingatron accelerates the module to launch velocities of many km/s as it exits the spiral track of the Slingatron.

See the bottom of this post for image: Design concept for a large Slingatron capable of placing small payloads into earth orbit.

Slingatron orbital launch sequence:

a. Payloads are attached to small rocket motor upperstages to form the launch module and then stacked in a launch rack feeding into the center of the Slingatron spiral track.
b. The Slingatron track is then accelerated up to the required gyration rate of tens of gyrations per second.
c. Each launch module is then released in sequence into the center of the Slingatron spiral at the beginning of its specified launch window.
d. The centripetal force of the gyrating Slingatron acts on and accelerates the launch module out into the Slingatron track.
e. As the launch module travels farther out in the spiral track it accelerates rapidly, staying in phase with the strong centripetal force gyrations acting on the launch module.
f. The launch module exits the Slingatron at a high velocity. A specially designed nosecone prevents the launch module from burning up during its brief but very hot flight through the dense part of the atmosphere.
g. Once the launch module reaches the desired altitude in its trajectory the upperstage rocket motor fires to circularize the orbit of the payload or satellite.
h. Payload modules delivering fuel or water instead of a free flying satellite are retrieved by a space tug and delivered to an orbital depot.

You may be wondering how the Electric Pulsed Plasma Propulsion technology fits in with the proposed Slingatron development effort. In our last thruster update I mentioned that we are now studying the use of a non-gaseous propellant that is completely inert, non-toxic, and requires no high-pressure propellant tanks or valves. This inert propellant is the perfect bulk cargo for an orbital Slingatron mass launcher. Therefore, the thruster technology is actually a component that fits into the top tier of this new space transportation infrastructure.

To give you an idea of the Slingatron’s launch potential here are a few examples of missions it could support*:

1. Low cost, on demand and fully reusable sub-orbital payload launches.
2. On orbit refueling of reusable launch vehicles to increase their payload launch capacity and performance.
3. Low cost rapid deployment of a low cost global satellite based internet.
4. Refueling of robotic spacecraft in a large-scale effort to remove and or recycle orbital debris.
5. Resupply of manned platforms and fueling of large interplanetary spacecraft.
6. Delivery of structures and raw material for large scale space based construction and manufacturing.
7. Sustained intercept and destruction of large, late-detected, earth threatening asteroids and comets.
8. Clean safe impact fusion energy becomes possible for velocities above about 20 km/s.

*We would like to hear your suggestions on potential Slingatron missions that would improve life both on and off earth.

Here are some expected advantages and disadvantages of the Slingatron:

Advantages:

1. Dramatic reduction of launch costs per pound.
2. On-demand launch capability
3. Rapid serial launch capability.
4. Slingatron can be built using existing technology and materials.
5. Energy efficient and extremely low launch emissions.
6. Modular construction enables low cost launch performance growth.

Disadvantages: (There is always a catch!)

1. All payloads will be subjected to a load of ~10,000-30,000 times earth gravity (g) during launch.*
2. Humans absolutely cannot be launched in a Slingatron.
3. Satellites, all avionics, and upperstages will have to be g-hardened. This will limit the complexity of satellites launched by the Slingatron.
4. The nosecone of the launch module will be subject to extreme heating during launch.

Why Kickstarter?

We want to use Kickstarter to create a global user base of people who are interested in, involved in, and some day use the Slingatron, for the benefit of earth. Your backer funds will be used to develop and test a modular scalable Slingatron to help us better understand the technical challenges and costs which lay ahead in the development of a large orbital launch machine.

Finally, we are very excited about this project and the prospect of your involvement in this effort to build what will essentially be the first ever analog for a railroad to orbit, which can open the frontier of space.

We would love to hear any comments that you may have on our proposed project.

Update #40

Continued Thruster Development

Hi Folks,

I just wanted to give you an update on our continued work developing
the electric pulsed plasma propulsion (E3P) technology beyond the
successful conclusion of our first Kickstarter project.

We have identified a unique new approach to using a non-gaseous
propellant, which maintains the same high Isp and thrust of argon or
xenon gas propellants in our thruster. This new propellant approach
provides the E3P thruster technology with the following advantages:

1) The non-gaseous propellant is completely inert and non-toxic, and
requires no high-pressure propellant tanks which can explode, or valves
which can fail. Given that the propellant is inert and non-toxic, it is
an ideal candidate technology for safe use with, and storage aboard,
manned platforms and on cubesats.

2) This thruster technology could enable interplanetary missions on
cubesat spacecraft as small as 6U (briefcase size spacecraft) and with similarly
low cost.

3) It is scalable up to large spacecraft in the kilowatt power range.

4) It can be throttled for fine maneuvering of the spacecraft.

5) Both the thruster technology and propellant are mechanically robust.

6) It has high thrust per unit area, taking up less space on the rear
of the spacecraft.

We are actively working on our next Kickstarter project which will be a
very cool space technology and which will be a complete surprise! We
think you are going to be very excited by its potential. We plan to launch
this next project in about a month from now, so stay tuned for further details from us!

Best,

Chris Faranetta
