Project EULER

ARIS’ first supersonic rocket

Flying to 30’000ft and enduring supersonic speeds for the first time, ARIS’s third rocket EULER paves the way for flying a self-developed hybrid rocket engine and sets another milestone towards flying student-built hardware in orbit.

Field of Studies

The sounding rocket EULER
Spaceport America Cup 2020

In June 2020, ARIS will send a student team to New Mexico, USA , to compete at the Spaceport America Cup for the third time. Building on the successes of Project Tell and Project HEIDI, Project EULER will develop and build a sounding rocket to reach an apogee of 30’000ft with a commercial off-the-shelf motor and bring the whole system safely back to ground. To fly to new heights, they will need to reach for the strongest solid rocket motors that are commercially available and design a system that withstands supersonic speeds.

The team consists of over 37 highly motivated students from ETH Zürich, ZHAW, HSLU, FHNW, EPFL and the HSR. Over the duration of approximately one year they will apply classroom knowledge, and acquire new skills to design creative solutions for the demanding challenges ahead of them.

Mission Objectives

Reach 30’000 ft.

ARIS strives to imporve and progress every year. Therefore, EULER wants to reach 30’000 ft. this year, something no project at ARIS has done before. A giant but doable leap!

First Place in 30k Category. 

Only reaching 30’000 ft. has never won someone an award. Therefore, appart from reaching the desired altitude we want to win the 30k category of the Spaceport America Cup.

Win Payload Challenge.

An ARIS Alumini will construct a special payload as part of his Master Theses. Having that payload on board wants us to win that category!

Origin of Project Name

Members voted democratically for the project name EULER. But what’s behind the name and who does it honor?

With the project name EULER we want to express our admiration for Leonhard EULER (15 April 1707 – 18 September 1783) who was a Swiss mathematician. He had two numbers named after him: the important Euler’s number in calculus „e“, approximately equal to 2.71828, and the Euler–Mascheroni constant γ (gamma) sometimes referred to as just “Euler’s constant”, approximately equal to 0.57721.
