The International Rocket Engineering Competition (IREC)
is held every June, sponsored by

the Experimental Sounding
Rocket Association (ESRA), now called the Spaceport America Cup

Слайд 3

“In general, student teams competing in the IREC must design, build,

and launch a rocket carrying no less than 8.8 lb of payload to a target apogee either 10,000 ft or 30,000 ft above ground level (AGL).”

The Spaceport America Cup (IREC)

This year, the competition runs from 16 June to 20 June 2020

Слайд 4

“Encourage participants to create payloads that accomplish a relevant function and

provide useful learning opportunities.”

The Space Dynamics Laboratory (SDL) Payload Challenge

Слайд 5

The competition
After your team decides to participate, then you must decide

on what rocket design to use…this is not an easy choice, since, generally, there are no kits that are this size and will go to that altitude.

Слайд 6

The competition
Throughout the year, the IREC judging committee requires lengthy technical

reports, which makes sense, since you are sending a heavy object very high at a very fast speed.

This year, IREC is using
the HeroX platform

Слайд 7

The competition
Using a simulation program (RockSim), your team must show the

rocket’s flight characteristics, including max altitude.

Слайд 8

The competition
During April and May, the club tests the airframe, decoupling

system, onboard computer and payload in a series of test launches at the Washington Aerospace Club’s Mansfield site.
We will not be able to use this site this year, so we will most likely use the Oregon Rocketry Club’s (OROC) Brothers, Oregon site.

Слайд 9

The competition
In the weekend after final exams in June, we drive

the completed rocket and team members about 2200 km southeast to the New Mexico desert. This distance is similar to the distance from Blagoveshchensk to Shanghai.

Слайд 10

The first day of the competition is the judging of the

rockets: this is held at the Las Cruces Convention Center, and lasts all day.

The competition

Слайд 11

The competition
The remainder of the week is spent at the launch

site near Spaceport America. Teams set up a “camp” with their own tents and tables and vehicles. Temperatures range from 5°C at night to 40°C in mid-afternoon.

Слайд 12

The competition
There are a lot of teams competing, and launch times

are precious.

Слайд 13

The competition
And many things that worked in lab stop working!

Слайд 14

The competition
But it’s all worth it when it launches…

2019 Project Ranginui
Dimensions: 2.67 m long, 15.2 cm outer diameter

Слайд 20

2019 Project Ranginui
Single-stage, solid-motor (M2500), apogee separation via electronically-triggered black powder

discharge, payloads also ejected by electronically-triggered black powder discharge

Слайд 21

2019 Project Ranginui
Two parachutes: the drogue (apogee deploy) and the main

(300 m deploy), both with a back-up system.
GPS monitors altitude, with real-time telemetry sent to a base station laptop in camp.

Слайд 22

2019 Project Ranginui
Detail of the electronics bay (“e-bay”): secured with eye

bolts on either side. The electronics is secured to the “sled” (right), and is shielded from the separation black powder charges (top and bottom)

Слайд 23

The payload
section
The payload will be approximately 4 u in volume, with

the “front” (coupler-side) 3 u reserved for the Amur State payload.

Слайд 24

The payload section
The NSC payload is an autonomous glider with a

preset spiral descent pattern

Слайд 25

2019 Project Ranginui
The first day, at the Las Cruces
Convention Center, the

present-
ation went well. People liked the
idea behind the АмГУ payload.

Слайд 26

2019 Project Ranginui
The result was less positive than we had hoped.

When we arrived in New Mexico, we had still not tested the parachute
deployment system. So we had to do that in someone’s backyard.

Слайд 27

2019 Project Ranginui
By the time we
were ready to
launch, the desert
winds

had
started, and all
launches were
cancelled.
Ranginui never
left the launch-
pad.

= 7.0 kg
=

4.0 kg

= 24.6 kg

Therefore, this year, we decided
to simplify the project that we
could finish building and testing
in Seattle by May. So we will make
a single-stage rocket and use a
single M1850W motor
(impulse = 7658.6 Ns) to
achieve 10,000 feet altitude
with a single “dummy” payload
— or maybe yours!
