My name is Alexander Filatov. The first version of the site contained my own projects (see Articles), library of books about development and production of aerospace engineering, and calculation of bipropellant liquid rocket engine for MosGIRD's project (some materials can be found in Knowledge Base).

At the moment the site is mostly about the amateur rocketry group from Saint-Petersburg, Russia. I am a member of the group.

Some short information about the site sections:

• Section "Our Group" contains news and future events information.
• Section "Projects" contains description of our current and old projects. If you would like to go in details, welcome to our forum (in Russian).
• In "Knowledge Base" section you can find calculation methods, reference data, and Russian laws about rocketry.
• Section "Soft" contains our own programs, used for calculation of rockets and engines. There is the list of other programs in the section Links.
• In the section "Articles" there are my articles mostly about interstellar flights, etc.
• "Links" - no comments.
