Scheurer Swiss supports the focus project «Daedalus» of ETH Zurich with its engineering know-how and networks the project team with partner companies.

The engineering company Scheurer Swiss GmbH, known for its many years of expertise with fibre composite technologies, is supporting ETH Zurich’s «Daedalus» project as a sponsor with its engineering expertise and is networking the project team with the right companies to produce the third generation of the hybrid rocket motor for this year’s ARIS «Piccard» rocket.

ETH focus project "Daedalus": Six ETH students develop the ARIS hybrid rocket motor for the "Piccard" rocket.

Six ETH students are developing this year’s ARIS hybrid rocket motor for the “Piccard” rocket as part of the “Daedalus” focus project.

Six space-loving ETH students are pursuing the concept with the goal of using the hybrid rocket motor to reach an altitude of 30,000 feet (about 9,150 meters) and win this year’s largest academic rocket engineering competition in the world, the Spaceport America Cup, as well as the first university rocket launch competition in Europe, EuRoc. Its hybrid rocket engine has just successfully completed static field testing and is ready for the first hybrid flight in ARIS history.

Development of the third generation of the ARIS hybrid rocket engine

The «Daedalus» focus project supported by Scheurer Swiss is part of ARIS – «Academic Spaceflight Initiative Switzerland» – which was founded in 2017 by students at ETH Zurich to promote spaceflight in Switzerland. Together, budding engineers, scientists and economists have since been developing systems for aerospace with the goal of advancing humanity by developing systems for space.

As part of ARIS, the «Daedalus» focus project is designing a third-generation hybrid rocket engine, which will be incorporated into this year’s ARIS «Piccard» rocket. What is special about the way a hybrid rocket engine works is the combination of a solid fuel with a liquid oxidizer. The coexistence of the two different aggregate states until immediately before ignition results in a high level of safety, as unintentional ignition can be largely prevented.

With the aid of the hybrid engine, the ARIS “Piccard” rocket is to reach an altitude of over 9,000 meters.

With the help of this engine, the rocket is expected to reach an altitude of 30,000 feet (about 9,150 meters), leading the six-member «Daedalus» development team of mechanical engineering students from ETH Zurich to victory at the world’s largest academic rocket competition, the Spaceport America Cup in New Mexico, and at the first university rocket launch competition in Europe, EuRoc in Portugal, in 2021.

First hybrid flight in ARIS history

The project kicked off in September 2020, and after the concept and design phase, which was supported by valuable input from industry and research experts, the final design of the hybrid rocket motor was already in place by December 2020.

ETH focus project "Daedalus": Integration of the hybrid engine into the ARIS "Piccard" rocket.

For the challenging integration of the engine into the “Piccard” rocket, the “Daedalus” team collaborated with experts in lightweight construction, including Scheurer Swiss.

The major challenge of the project is the integration of the engine into the «Piccard» rocket, as this places high demands on the design of the engine. For this reason, the six-member project team worked closely with experts in lightweight construction. «To achieve our ambitious goals, we depend on competent industrial partners in the field of fibre composite technology. Scheurer Swiss, with its many years of experience in high-performance composite engineering, was ideally suited for collaboration in our eyes,» emphasizes project manager and media spokesman, Aaron Ehrat.

The ETH “Daedalus” team agrees: the data collected during the two-month extensive static test campaign show that the hybrid engine is ready for its flight in the “Piccard” rocket.

After an extensive two-month test campaign, during which the performance of the engine in the rocket was tested, the «Daedalus» project team at ETH Zurich has completed the static tests on its hybrid rocket engine with great promise: «The course of the entire test campaign was extremely successful and the data collected shows that we are ready for the flight of our engine in the rocket.», says Adrian Fuhrer, Hybrid Rocket Engineer, and adds: «The great support that Scheurer Swiss provided us, especially at the beginning of the project, in the field of composite engineering and the networking with other competent partners for lightweight construction and fibre composite technology, was very valuable for us and made the project possible in the first place.»

Scheurer Swiss CEO, Dominik Scheurer, praises, «ETH Zurich’s focus project «Daedalus» exemplifies how highly efficient technical systems with great potential for success can be developed with the use of fibre composite materials and lightweight construction technologies. We congratulate the «Daedalus» team on the successful test series and are pleased that we were able to support the team with our engineering expertise and network it with our partner companies in a target-oriented manner. Now it’s time to keep our fingers crossed for the maiden flight of the «Piccard» rocket in July!»

Scheurer Swiss supports the focus project “Rowesys” – Robotic Weeding System – of ETH Zurich with its engineering know-how and supplies 3D-printed carbon-reinforced robot components.

The engineering company Scheurer Swiss GmbH, known for its many years of expertise with fibre composite technologies, is supporting the “Rowesys” – Robotic Weeding System – project of ETH Zurich as a gold sponsor with its engineering expertise and is printing carbon-reinforced 3D components for the agricultural robot on behalf of the team. With this concept, ten motivated ETH students are pursuing the goal of developing a sustainable alternative for the use of herbicides in agriculture. Their autonomous agricultural robot for weed removal has just gone into practical testing.

Carbon-reinforced material revolutionizes agriculture

“Rosie”, the unprecedented autonomous agricultural robot, was developed by ETH students in collaboration with Scheurer Swiss as a gold sponsor and is expected to replace pesticides in the future.

The ETH Zurich focus project “Rowesys”, supported by Scheurer Swiss, impressively demonstrates how damage to people and the environment can be minimised with the help of digitalisation and smart technology. With this goal in mind, ten motivated ETH students, supported by eight expert coaches and sponsors, have been working on the development of the “Rowesys” agricultural robot since last September.
The underlying concept is based on mechanical weed killing. The result is a functional prototype for sugar beet fields, because these require a relatively high use of herbicides. “Rowesys” already meets the requirements of an autonomous agricultural robot in terms of efficiency, reliability, autonomy, safety and user-friendliness to a large extent. Not least thanks to the use of cost-efficient carbon-reinforced material from the 3D printer, which, in addition to the monetary benefits, also offers practically unlimited design possibilities.

For example, the agricultural robot has been equipped with wafer-thin carbon-reinforced plastic slats that are backed by LEDs to indicate the robot status at all times.

Another filigree component in turn serves as an interface between the aluminium chassis and the robot’s electronics. The unusual shape of the connector is designed in such a way that not a single gram of superfluous material is used, so as not to weigh down the robot unnecessarily. At the same time, the component must be ultra-stable to hold the connection.

“Only with the technology of carbon-reinforced 3D printing is it even possible to produce such a precisely fitting, filigree and yet stable component.

The carbon reinforced 3D printing technology recommended by Scheurer Swiss is the perfect solution in terms of lightweight construction, design flexibility and stability as well as manufacturing time and production costs.

We supported the Rowesys team with our know-how in the field of fibre composite technologies in an advisory capacity and operationally incorporated our many years of expertise from the development of highly efficient composite components for motor sports into the development and 3D printing of the carbon-reinforced components for the agricultural robot,” explains Dominik Scheurer, CEO of Scheurer Swiss GmbH.

The agricultural robot is to replace pesticides

The agricultural robot pulls small ploughs through the soil, which destroy the weeds between the rows of plants by pulling the roots to the surface from the ground where the weeds dry up. The robot drives autonomously through the rows, detects the end of the field with the help of the built-in cameras and switches to the next untilled row. This process is repeated until the end of the field is reached.

The “Rowesys” project at ETH Zurich, which is supported by Scheurer Swiss, impressively demonstrates how damage to people and the environment can be minimized with the help of digitalization and smart technology.

The practical test has shown that with “Rowesys” both the use of herbicides and the pollution of groundwater, air and produced goods can be massively reduced. “What motivated me about this project, apart from the relevance of what I learned and the chance to gain practical experience in teamwork, was the sustainability of herbicide-free sugar beet cultivation. Because up to now, there has been no investment in more sustainable production in this area of agriculture,” says Nico Burger, Software & Controls Team Rowesys.
“The focus project “Rowesys” is an example of how digitisation and the use of innovative materials can produce efficient and intelligent technical achievements. We congratulate the Rowesys team on their success and are pleased that we were able to support the team with our expertise in an advisory and operational capacity right up to the practical test”, Scheurer announced.
