In an abandoned Soviet camp near Kaluga with the name "Millennium Falcon", the first All-Russian rocket-building championship took place. I also asked for it, because a jetpack is closer to missiles than to aviation. Yes, and look at 10 year olds who assemble a really working contraption from scotch tape, drawing paper and a plastic bottle, and a little older comrades shoot a rocket at 400 meters - it's worth it.
Summary:
Tracks
Competitions were held on three tracks.
- "Water rockets" - for schoolchildren 10-14 years old.
- "Solid propellant rockets" - the age of participants is 14-17 years old.
- "Open Sky" for student teams preparing for international competitions (flight up to 10 meters).
water rockets
From my Soviet childhood, when plastic bags were still washed and dried on clothespins, and cans of fanta and beer were elite collectible luxury items, I remember this thing:
And then there were plastic bottles and the golden age of water rockets.
Punk style rocket.
One of the world's largest water rockets.

How was it with us
Participant age: 10-14 years old
First stage. It was necessary to design and build a water rocket with
electronic on-board system and rescue mechanism based on (Arduino).
The second stage. It is necessary to design and build a rocket without a designer (of our own design) with an electronic on-board system and a rescue mechanism. There are no design restrictions. Task - reaching the maximum height.

solid rockets
First stage. It is necessary to design and build a rocket with a launch weight of up to 1150 g. with an electronic control system and a rescue mechanism based on arduino.
The second stage. Design and build a rocket of your own design (without using a designer) with an electronic control system and a rescue mechanism.
*Teams that have passed the first stage or student teams are allowed to the second stage.
We fly on these engines:
TTX RD-100Solid propellant engine for rocket models RD1-100-7 will lift the rocket to an unattainable height! The dream of rocket modellers about a powerful MRD that competes with Western counterparts has come true.
Russia is back in the space race with the US! The model rocket engine RD1-100-7 is much more powerful than the Soviet MRDs. Now Russian rocket modellers can safely brag about spectacular launches in front of their Western colleagues.
This engine for rocket models continues the well-established RD1 line. Special manufacturing techniques and high-precision calculation of the surface area have significantly increased engine power.
The new rocket engine is designed primarily for experienced rocket modellers.

TERMS AND CONDITIONS OF OPERATION
Store in a dry place at temperatures from -20 to +30 ˚С.
Ignition is carried out with a specialized electric fuse (supplied).
Insert the fuse to the stop to a depth of 36 mm.
Keep at least 10 m away while the engine is running.
Modification of the engine is strictly prohibited.

Student teams preparing for international IREC competitions
Design and construction of a rocket for flights to an altitude of 3 to 000 meters with a 10 kg payload on board.
The cost of launching a rocket, taking into account the engine: 24 rubles.
This is how the international championship is held in America.

Beginning in 2017, ESRA's Intercollegiate Rocket Engineering Competition (IREC) became the flagship activity of a new annual event called the Spaceport America Cup (SA Cup).
Out-of-competition participation "Master"
If you are suddenly over 23 years old and want to build rockets, then you can register a team on any of the tracks, indicating the category "Master". But launches at your own expense. The cost of solid propellant engines is from 5000 to 35 rubles.
News from the fields
Flocks of schoolchildren with scientific supervisors arrived and began to get junk out of such boxes.
And collect your rockets.
Scotch, whatman paper, plastic bottle ...
... and some arduino - the rocket is ready.
But these guys will definitely do Elon Musk:
And girls.
First test launches at the airport
It was raining and a water rocket.
“Knowing the path and walking it are not the same thing.”
The collision with reality has benefited many rocket scientists. Someone finally understood why a parachute is needed.
Refinement of missiles before the final
A 3D printer prints for a long time ... you can think about the past years ... about all ten ...
Master class on RimWorld while the fairing is being printed on a 3D printer:
- Where is your dog?
- Well, she's dead.
- Why did she die?
- That's because of whom she died, I buried here.
All and sundry joked about "Space Y".
Second run to the airfield and final launches
A team of girls, one of them is 10 years old. They are waiting for their turn.
Contacts for remote start.
The pilot tries to escape from the rocket.
Red button.
Launch control panel.
Take care of your baby.
"Rocket with wrong formulas". They are trying to adjust the electronics before the start, although it is raining.
You need to come to the start with a fully assembled rocket, but as always.
Is it right?
Vzhzhzhzhuuuu!
And then the rockets started to land...
Original body design. But if they didn’t release a parachute - cranks.
Sometimes the parachute was released, but it did not open - also krants.
And again.
And again.
In one of the rockets that landed, we actually found an earthworm.
Behind the scenes were search teams that ran through the swamp and dug fairings, climbed birch trees for a payload. There were those who successfully took off and landed, but who cares?
It was fun and inspiring.
I hope that rockets will fly to the Moon and Mars, and not neighboring continents.
The most important thing
Lunch at the airport.

PS
A rocket got stuck on a tree, a parachute got tangled, and everyone began to call me together because I have a jetpack. But I still don’t know how to fly, but I can tie the apparatus to the bars:
