The external protective case of the Can Satellite ("Can Sat") is a structural enclosure designed in the shape of a commercial soda can.
It serves as a physical shield for internal electronics, enhances aerodynamic stability, and ensures realistic environmental conditions for experimental testing.
Primary Functions of the CanSat Protective Case
Protection Against Physical Impact
Safeguards internal electronics (e.g., main board, sensors, battery) from shocks, vibrations, and friction experienced during launch and descent.
To reduce the risk of circuit damage or wire disconnection upon landing, the case is typically made of durable materials such as metal alloys or composite structures.Compliance with Shape and Dimensional Standards
Designed to mimic the dimensions and shape of a real beverage can, ensuring compatibility with launch mechanisms and accuracy in standardized testing.Component Mounting and Alignment
Internal boards are stacked and secured within the case in a layered structure.
Anti-rotation grooves, rubber spacers, and mounting screw holes are included to keep components firmly in place during dynamic movements.Environmental Access for Sensor Operation
For sensors requiring exposure to the external environment (e.g., barometric pressure, light, or camera), custom openings are integrated into the case.
These ports are sealed with silicone rubber or EVA foam pads to provide waterproofing and dust resistance.Aerodynamic Stability
The case helps stabilize the CanSat during descent by reducing rotation and oscillation.
Proper mass distribution is essential to maintain a balanced center of gravity and predictable flight path.
Protective Case – Component Description (Based on Image Reference)
Component | Functional Description | Notes |
|---|---|---|
Circular Top and Bottom Covers | Made of metal or plastic; serve as the upper and lower structural ends of the CanSat case | Provide enclosure and structural integrity |
Internal Silicone Rubber Ring | Provides routing paths for communication antennas, sensors, and camera access to the outside | Allows environmental exposure while sealing gaps |
Vertical Support Rod (Bottom) | Acts as an internal fixture to vertically align and secure circuit boards within the case | Ensures stable stacking and internal positioning |
Summary
The CanSat protective case is more than just an outer shell—it is a critical hardware component designed to enhance the satellite’s safety, sensor operation, experimental validity, and aerodynamic stability. Its structural and functional design reflects a high level of engineering precision tailored for real-world space-related testing conditions.
