Lin Industrial is a Russian startup business that believes sending satellites into space should be less epic blastoff and more paper airplane.

Only recently entering the Skolkovo fold as a resident, the company already has a co-investor and is filing for a grant to develop ultralight rocket technology that it says will make escaping earth’s gravity child’s play.

Once it's off the drawing board, the Aldan rocket – named after a gold-flecked river in Far Eastern Siberia – will be able to shuttle microsatellites to low-earth orbit for a fraction of the current costs, which stand at around $80,000 per kilogram, the company says.

“The appearance of this kind of rocket will bring about fundamental changes in this growing market. Young companies, science institutes and universities will be able to send their own satellites into space cheaply and quickly,” says Lin Industrial chief technical officer Alexander Ilin.

Internationally the company sees stern competition from Virgin Galactic, Interorbital Systems and Rocket Lab, but looks likely to find domestic success more quickly as the only firm to service small payloads of up to 100kg.

“No one even wants to get involved in such tasks except us,” the firm’s general manager Alexey Kaltushkin says.

As technology advances, more and more companies are scaling down their satellites to cut costs. This paves the way for whole networks of micro- and nano-satellites to be established, ideal for providing mobile phone coverage in remote areas or to monitor traffic in real time, he says.

There are also myriad military uses for small satellites, making the deep-pocketed defense industry a potentially key client, Kaltushkin says.

The rocket is to use liquid oxygen and refined kerosene as propellаnts

“We are counting on cooperating with United Rocket and Space Corporation and Roskosmos in the future, of course,” he adds, referring to the government agency responsible for space activity.

Getting the business off the ground may not be as simple as the potential rockets themselves, however. Lin Industrial estimates it needs to raise at least 500 million rubles ($13.5 million) to get to the stage where it can launch a prototype rocket.

Currently, the company has completed an engineering study into the fuel delivery system and is designing the prototype.

Looks interesting... is it really using an RD-0110 engine there? Looks like it.

I do! but nobody around me wants... :shrug::lol:
Hope they'll got some good result

BTW how about to create an Orber-forum international design team for launch vehicles? :lol:

I would join it. At least if Loru also takes part for the visuals. :thumbup:

How would they be competition in the CubeSat launch market?

Virgin Galactic has plans to use something called Launcher One with their White Knight aircraft to launch small satellites. Launcher One would be carried where Space Ship 2 would normally be, and that's the extent of what I know for sure about it.

Many thanks to everyone for paying attention to our proposal. We don't give up the Aldan project currently, but we are also considering another project, called Taymyr, as well. That latter one is tailored to the requirements of the production plant which we have signed a cooperation agreement with.

This is an ordinary civilian machine-building plant (not a special "space" plant). We want to use one of their workshops to assemble modules of the Taymyr. To cut back the launch costs we are going to use pressure feeding, a MEMS gyroscopes based guidance system (our in-house design) and engines using non-cryogenic enviroinmentally friendly propellants (Peroxide + Kerosene). The structure of the tanks - coiled up, composite.

We are looking to have the engines for the Taymyr designed by Academic Department 202 ("Rocket Engines") of Moscow Aviation Instutute, because they have an experience in development of peroxide engines. We have an agreement with them.

Yes, the rocket looks a bit weird - employing simple guidance algos, but on a new hardware components, pressure feeding of propellants with a mediocre SI, but composite structure.

All that we do to dramatically cut back on the R&D time and the cost of the rocket (both development and launch expenditures). Today I'm planning a meeting with representatives from Kapustin Yar - since it's hardly suitable to launch such a rocket off any Gorky Park lawn :)

Let me guess - Angara-like modular structure?

I have a bad feeling about this. I'd be happy if you succeed, but right now I'm quite skeptical. Do they really have all the technology needed for a space rocket on a civilian plant? What about electronic components - do you have access to spaceworthy electronics? It would be sad to see another Fobos-Grunt failure.

Military polygon? Do you plan to build the whole launch installations complex for your rocket there and then leave it to military guys, or do you want to use it as your future space-port in the future? Wiki says it is only 48,4-50,7 inclination range accessible from there.

Don't get me wrong, I would be a happiest SOB here if your thing fly one day. But you can understand my feelings after all what happened last years with our spacecrafts.

As far as I understood, it's only for assembly. Since the rocket will be pretty small scale, I wouldn't expect much very specialised equipment to be neccessary to put the parts together.

I can agree partially... I don't see many reasons to be scared there, since many parts of a rocket are really build in standard workshops from early history on, but: For everything that involves peroxide or oxygen, better use some higher standards. Especially since you also need welding techniques for both, that require some more care. And when installing rocket engines, its at least recommended to have a clean air tent around the rocket thrust section.

For the electronics, you are right, its better to be safe than sorry. But you could try. If the rocket has its job done in 10 minutes and has a 2% chance of exceeding the redundancy (that you hopefully build into the guidance electronics in that time), its fine.

Sounding rockets also rarely use the extremely expensive chips, but simply conform to lower standards of radiation hardening. They must not operate for years in space.

Phobos-Grunt is just a warning, that you should not do this without proper ground testing first. A strong faith is no replacement for proper testing.

The rocket is only 14 meter long, in theory, you could transport and launch it from a truck trailer. Practically, maybe you could at least have containerized ground equipment and be flexible there, should "The Powers That Be" have other plans.

Baikonur would be far out IMHO as option, since you would need to hit the stage drop zones of the other rockets... pretty annoying to get a good performance that way.

Even using the new (and badly misorganized) spaceport at the pacific coast would be possible if you are flexible enough. The less support you need from outside and the faster you can adapt to new conditions, the better the chances are that you will not fail (that often).

Wrong guess. Unlike the makers of the Angara we don't use engine throttling and don't ignite all the modules while still on the ground. On the ground the 4 side boosters are ignited, the core module will start while already in flight. It has a high-SI high-altitude nozzle (not shown at the picture).

I have a bad feeling about this. I'd be happy if you succeed, but right now I'm quite skeptical. Do they really have all the technology needed for a space rocket on a civilian plant? What about electronic components - do you have access to spaceworthy electronics? It would be sad to see another Fobos-Grunt failure.

No, of course, no one can suddenly start building rockets from scratch. We are going to equip one of the workshops with a tank winding machine. A firm which may churn out the design is our partner now. They are winding air bottles for divers and mountaineers now.

Our rocket has a guidance system much simpler than an interplanetary probe needs. And also it should work still in the thick air where the risk of being affected by energetic charged particles is significantly lower. We already have a guidance system prototype, the only thing we need :) is to test fly it on a small rocket.

Military polygon? Do you plan to build the whole launch installations complex for your rocket there and then leave it to military guys, or do you want to use it as your future space-port in the future? Wiki says it is only 48,4-50,7 inclination range accessible from there.

We are going to use a site which the meteorologists use, not any military one. It's a fair exchange - they provide us the site, we offer them a possibility to deliver their instruments to 100 km altitude. The exclusion zones for jettisoned booster parts is a specific problem we'll touch in the course of development of the project. It's possible that our rocket might go to other inclinations as well. We also had preliminary talks with Plesetsk, but their offers are too expensive for us.
