¶ Onboarding Information
¶ Chalmers Aerospace Society for Advanced Rocketry
This page will take you through all the information you need for your journey with CAESAR to become a rocket engineer. First, you need to set up all the tools and infrastructure that we use.
¶ About CAESAR
CAESAR is a non-profit organization. The organization is governed by a board that is elected at our general meeting each spring.
¶ Team handbook
If you need information about the society, how to access resources or your membership, you can find answers in the Team Handbook.
¶ Expectations and meetings
The entire team meets twice a week, on Mondays and Wednesdays at 17.30, to work together. We have booked SB3-L110 and have a space in Armeringshallen to work in.
More educational meetings will be offered as needed. This may involve going over CAD or theoretical concepts.
You are expected to attend meetings and contribute work outside of them. Collaboration with your teammates is encouraged even outside of regular meetings.
¶ You are responsible for doing your assigned work
If you have taken on greater responsibility, for example, a task with a critical deadline, it is important that you inform your sub-team if you realize that you will not be able to meet it or if other problems arise. The same applies if you want to take a break or leave the team. You need to notify your sub-team so that they can reallocate the work effectively. Otherwise, we will not be able to reach our goal and see our rocket fly.
¶ Help CAESAR grow
As part of the team, we’d love your help in driving CAESAR’s growth and expanding our outreach through events such as career fairs.
¶ CAESAR and T-RAX membership
You have to renew your membership in CAESAR every new academic year. You also need to become a member of T-RAX as soon as possible to get access to the Fuse spaces. It will cost you 100 kr, and the information regarding this can be found in the link below.
¶ Tools
¶ Communication
We use Teams for communication, so it's important that you check in regularly so you don't miss anything.
For communication, tasks, and sharing general files and research papers, we use Microsoft Teams. It is important that you check Teams regularly to avoid missing important information.
Please respond to messages – even a simple thumbs up or thumbs down helps a lot!
You will be invited via your student email to a team called "Student.CAESAR", a chat called "CAESAR", and a chat for your specific sub-team. If you have not been invited or have any issues, contact a team leader.
The Team is used for sharing files and pictures, getting assigned and viewing your tasks via the To Do tool, and accessing meeting protocols. The chats are used for online meetings, general announcements, and communication.
Microsoft SharePoint is another way we use to access and work with the Team's files, if you prefer it.
¶ CAD
For CAD and 3D modeling we use Autodesk fusion. We use this to share all the CAD for the rocket and anything surrounding the project, organized into folders for each sub-team. You will be invited to this folder via your student email. You will need to get a license via Chalmers and download fusion on your computer if you don't already have it. You can get it via the link below.
¶ Rocket design
Our current rocket design is a hybrid rocket using paraffin wax as solid fuel and nitrous oxide as a liquid oxidizer, designed to reach an altitude of 3 km. The combustion chamber and oxidizer tank are built into the aluminium tube at the bottom, with 3D-printed plastic making up the top of the fuselage. The fins will be passive, and no explosives can be used for any task on the rocket due to Swedish laws and regulations.
It will carry a payload consisting of four PocketSats, with a total mass of 1 kg. The rocket's flight computer will have GPS, altitude sensors, pressure sensors, and wireless communication with the ground. It will also control the parachute ejection parachute ejection and the throttle.
The parachute is a two-stage recovery system, with a drag chute deployed soon after apogee to provide a controlled descent. The main parachute is then deployed shortly before touchdown to reduce the landing speed to a safe level while ensuring that the rocket does not drift too far from the launch site. Below is a picture showing all the major parts of the rocket.
¶ Team specific information
Here you can find specific information for each team. You should read the page for your specific team.
¶ Learning materials
If you feel unsure about any physical or technical details, or just want to learn more about rockets, we have a page below where you can find plenty of resources:
If you still have questions, don't be scared to contact a team leader or a previous member of the team. We are here to learn. We have worked on this project for a long time, and even though we don't know everything, we know a lot. If the person you ask doesn't know the answer, they may be able to point you towards someone who does.
