“Look, what a jetpack I have!” - “Ha, look what a rocket I have!” (Notes from the rocket building championship)

In the
Summary:

Tracks
Competitions were held on three tracks.
- "Water rockets" - for students aged 10-14.
- “Solid fuel rockets” - age of participants is 14-17 years.
- Open Skies for student teams preparing for international competitions (flight up to 10,000 meters).
Water rockets
From Soviet childhood, when plastic bags were still washed and dried on clothespins, and tin cans of forfeit and beer were elite collectible luxury items, I remember just such a thing:

And then plastic bottles appeared and the golden era of water rockets came.

Punk style rocket.

One of the largest water missiles in the world.

Foreign championships have been held for a long time and quite fun

Even NASA has water rocket manuals :

How was it with us
Age of participant: 10-14 years.
First stage . It was necessary to design and build a water missile with an
electronic on-board system and a rescue mechanism based on the designer (Arduino).
Second stage . It is necessary to design and build a rocket without a designer (own development) with an electronic on-board system and a rescue mechanism. There are no design restrictions. The task is to achieve maximum height.
Correspondence tour and video reports:
Solid rocket
First step . It is necessary to design and build a rocket with a launch weight up to 1150 with an electronic control system and rescue mechanism based on the Arduino designer .
Second stage . Design and build a rocket of its own design (without using a designer) with an electronic control system and rescue mechanism.
* In the second stage are allowed teams that have passed the first stage, or student teams.
We fly here on these engines:

TTX RD-100
Solid propellant engine for models of rockets RD1-100-7 will lift the rocket to an unattainable height! The rocket-modellers' dream of a powerful rocket engine competing with Western counterparts came true.
Russia joins the US space race again! The model RD1-100-7 rocket engine is much more powerful than the Soviet MRD. Now Russian rocket-modellers can safely boast of spectacular launches in front of their Western counterparts.
This engine for rocket models continues the well-established RD1 line. Special production technologies and high-precision surface area calculations have significantly increased engine power.
The new rocket engine is designed primarily for experienced rocket models.
RESTRICTION ON AGE

Channel length 195 mm
Weight 200 g
Thrust impulse total 100-110 N ∙ s
Maximum thrust 120 N
Average thrust 50 N
Charge burning time 2 s
Moderator burning time 7 s.

TTX RD-300
The solid propellant engine for the RD1-300-0 rocket models will lift the rocket to an unattainable height! The rocket-modellers' dream of a powerful rocket engine competing with Western counterparts came true.
Russia joins the US space race again! The RD1-300-0 model rocket engine to overtake and overtake, and we did it. The most powerful engine that can be ordered only from us.
RESTRICTION ON AGE
From 16 years!
TECHNICAL CHARACTERISTIC
Maximum thrust 330 N
Average thrust 180 N
Charge burning time 2.5 s
Burning time of the moderator - no.
CONDITIONS AND RULES OF OPERATION
To store in a dry place at a temperature from -20 to +30 ˚С.
Ignition with a specialized electric fuse (supplied).
Insert the igniter all the way to a depth of 36 mm.
While the engine is running, it is at a distance of at least 10 m. It is
strictly forbidden to modify the engine.

Here's how the engine works:
And here is a crazy experiment with a solid rocket engine:
Open sky
Student teams preparing for IREC international competitions
Design and construction of a rocket for flights at altitudes from 3,000 to 10,000 meters with 1.5 kg payload on board.
Rocket launch cost including engine: 24,000 rubles.


This is how the international championship in America goes.
The Intercollegiate Rocket Engineering Competition has been held since 2006.

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 by specifying the “Master” category. But start at your own expense. The cost of solid fuel engines is from 5,000 to 35,000 rubles.
News from the fields

Flocks of schoolchildren with supervisors arrived and began to get junk out of such boxes.
And collect your rockets.

Scotch tape, whatman paper, a plastic bottle ...

... and a bit of arduino - the rocket is ready.
But these guys are definitely doing Ilona Mask:




And the girls.
The first test launches at the airport



It was raining and a water rocket.



“Knowing the path and going through it is not the same thing.”
Collision with reality has benefited many rocketers. Someone finally understood why a parachute was needed.
Finalization of missiles before the final

The 3D printer prints for a long time ... you can think about past years ... about all ten ...

A workshop on RimWorld is still printing a fairing on a 3D printer:
- Where is your dog?
- Here, she died.
“Why did she die?”
- That's why she died, I buried here.

All and sundry joked about "Space J".
Second run to the airport and final launches

A team of girls, one of them is 10 years old. Waiting for their turn.

Contacts for remote start.

The pilot is trying to escape from the rocket.

Red button.

Launch control panel.

Take care of your baby.

"Missile with the wrong formulas." Try to tune the electronics before starting, although it is raining.

You need to come to the start with a fully assembled rocket, but as always.

Is it exactly?

Vzhzhzhzhuuuuh!

And then the rockets began to land ...

The original design of the hull. But if you didn’t release the parachute - krants.

Sometimes he released the parachute, but it didn’t open - also krants.

And again.

And again.

In one of the landing rockets, we actually found an earthworm.
Behind the scenes were search teams that ran around the swamp and dug fairings, climbed birch trees for the payload. There were those who successfully took off and landed, but who cares?

It was fun and inspiring.
I hope that the rockets will fly to the Moon and Mars, and not to the neighboring continents.
The most important thing

Lunch at the airport.

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