Year of Astronautics

Yes, GDJ, it is specially designed for fins material based on рhenolic, good strength , low density, manufacturability.

 

Seems to work well. I may try this once I get tired of Basswood.

 

Basswood good material, but requires skill for the best result. My way easier.

 

Easier in what way? I'm curious to know.

 

Production method does not require skill and experience in working with wood, in the production is iron works.

 

I see. Do you use hydraulic shears and other metal cutting tools for the phenolic?

 

... in the final form of the fins are not processed, only edge.

 

High-altitude rockets in two stages.

 

Those look really nice! How do you ignite the upper stages?

 

Good question, Qquake2k, thank you. Critical cross-section of the nozzle HELIUM-10 0.95 mm, internal igniter at a distance of 14 mm from the end of the motor. At the upper stage used motors without any additional technical improvements. That is, the motors can be interchanged. It's easier for me to show it in the pictures, than try to tell you about it. System of ignition works with any type of propellant charge, end burning or channel, complete unification.

 

I would love to see more photos.

 

Photo with some of the events "indoors", popularization and propaganda in the "one bottle". Photo made before the Process started, then a few hours fuss, no time to shoot ...

 

Congratulations to All with the Anniversary of the beginning of the Space Era of Mankind!

Rocketeers in Moscow celebrate the anniversary in their own way. Preparation and training launch of rocket

As they say in the good movies: "five years have passed...", unfortunately, the weather is not getting better, but rockets are launched regardless of this. Many different events happened. I will continue to tell for all about my rocketry experience. My English has not improved, I ask for understanding as much as possible.

 

I'll keep the timeline.

 

April 12, 2014, the anniversary of the flight of Gagarin, this time at VDNH was a big reconstruction, our launch pad moved into the courtyard of the House of Culture.

Preparation for rocket launches.

 

Ready for launch.

 

Rockets in the sky!

 

The launch weight of the rocket is about 40 grams. Trust curve of motor following.

 

The launch crew

 

Grandfather of all MLRS systems. ''Katusha'' and Studebaker.

 

It's half-scale, look for the truck..

 

This is lovely stuff, thanks for sharing!

Any chance you could take a pic of the motor that goes with that thrustcurve?

And the flames on the later ones look more yellow, different motor I presume?

 

Yes, different motors and different solid propellant formulation. Model rocket motors tend to be a strong compromise for manufacturability and low cost, as a consequence of this low case pressure. Different color of the flames is the effect of solid propellant components for sustainable combustion and a certain burning rate.

 

I'll inform you, a little patience please.

 

B Big rockets have the same thing.

 

May 2013, Student festival " May's take off". Moscow, Tushino airfield.

 

Look through the" keyhole " inside the rocket 9м17м (AT-2 SWATTER)

 

July 27 took part in the youth Forum "I am a citizen of the Moscow region."
