Every mechanical engineer responsible for the design of the structural frame of a satellite must ensure its ability to withstand the entirety of the loads imposed on it throughout the course of the mission.

The CubeSat structural design from ISIS is simpler that its competitor. The design created allows CubeSat developers a high level of freedom in their spacecraft configuration. It is compose by two layers of structures: - Primary Structure: consist of two modular side frames connected with four ribs, joint together with M2.5X6 screws. Although there is no friction in the space vacuum to stress the satellite’s structure, the extreme temperature changes due to the constant interchange of its trajectory between direct sunlight and eclipse render the usage of materials capable of maintaining their size and shape necessary. The CubeSat Kit 3D CAD models are of CubeSat Kit components and assemblies. CubeSat Structural Frame. 3D Models of the CubeSat Kit . The CubeSat Kit is designed and modelled using SolidWorks®.

The Structural subteam ensures the CubeSat’s structural integrity by paying attention to every small detail in the design.

The stacks of PCBs and other flight modules can be build up first in the secondary structure and integrated with the load carrying frames … A custom patch antenna has already been manufactured in Read more…, Division of Hydraulics & Environmental Engineering, AUTh, The members of ASAT-Rocketry are excited to announ, In the last few months, ASAT's Rocketry team manag, Aeronautics project during its design session. Each compressed zip file contains up to 4 file types (listed by suggested preference): 1. The ISIS 3-Unit CubeSat structure is developed as a generic, modular satellite structure based upon the CubeSat standard. Preliminary Design of the nanosatellite’s structure.

This task might seem easy to perform at first, but an appropriate analogy could be the following: Imagine your smartphone having to work properly while being exposed to a hot furnace on one side and liquid nitrogen on the other side.

The Thermal Sub-Team will  therefore select the appropriate thermal components to be used inside our satellite, namely heaters and insulation materials (MLI blankets). Every part as well as the frame of the CubeSat in its entirety are examined via static and vibrational analysis. It will be primarily responsible for coordinating and performing the basic functions required for the operation of the Read more…, Structural Subsystem In CubeSats, structural engineers are trained to design the ‘bones and muscles’ that create the form and shape of the nanosatellite. designing, building, and preparing a CubeSat for flight. The ease of fabrication and assembly, light-weight, and free space for the payload sensors, circuitry, and batteries are the key features of the CubeSat structural subsystem design. STEP (*.STEP) solid/surface Geometry; version AP214 4. The lack of atmospheric particles means that the only way to transfer heat is using radiation. On-Board Computer Subsystem The On-Board Computer (OBC) subsystem is considered to be the “brain” of the satellite. At a later stage, the Thermal Sub-Team will be responsible for the conduction of thermal vacuum tests, which will verify the accuracy of the Thermal Analysis performed and guarantee that the CubeSat can withstand the tough conditions of space. If a component fails to pass these tests, it is then redesigned from scratch and reshaped in the correct way. Structural/Thermal team (Dimitris, Nikos, Vasilis, Vasiliki). To orchestrate the above, it is also crucial to perform the so called “Thermal Analysis” using simulation software. Furthermore, what must primarily be taken into consideration are the extremely intense forces and vibrations developed during launch onboard the rocket setting the satellite into orbit. The design created allows CubeSat developers a high level of freedom in their spacecraft configuration. CubeSat Design Specification (CDS) Revision 9 Release State Additional Restrictions X Public Internal Confidential Controlled ITAR Work in Progress Inactive Revision Date Authored by Notes 8.1 05/26/04 Amy Hutputtanasin 9 5/15/05 Armen Toorian Updated specification. The Structural subteam ensures the CubeSat’s structural integrity by paying attention to every small detail in the design. The Thermal subsystem consists of three members: Vasiliki, Dimitris and Nikos, all of whom are undergraduate Mechanical Engineering students at the Aristotle University of Thessaloniki. The CXBN-2 satellite required a novel payload which …
What’s CSLI, you ask? The CubeSat Kit 3D CAD models are of CubeSat Kit components and assemblies. The aforementioned restrictions are essential in the prevention of the deployer’s overload with excessive weight and the uncontrollable rotation of the CubeSat after its release in space. SM CubeSat Structure belongs to the family of nanosatellites structures designed to ease cubesat integration and design offering the maximum level of flexibility and compatibility with commercial hardware. Another obligation of the subsystem is the adjustment of the total mass and its distribution along the body of the satellite. CubeSat Structural Frame NanoAvionics CubeSat Standard Structure has been developed as a generic, modular nanosatellite structure compliant with the CubeSat Design Specification. It is therefore important to dissipate the heat throughout the satellite and radiate the excessive  amount during the eclipse if possible. This work presents a cubeSat metallic structure design, which considered vitroceramics coatings.

The Structural subteam consists of Vasilis and Christos, both undergraduate students in the Mechanical Engineering department of Aristotle University of Thessaloniki (AUTh), who are currently working on the new analyses for the improvement of the satellite’s sturdiness. Thanks to optimized mechanical design, each CubeSat structure offers outstanding mechanical characteristics combined with light weight and compatibility with multiple commercial …

- Secondary Structure: it is stack up circuit board system in order to enhance the integrity of the satellite. The stack of PCBs and other flight modules can be build up first in the secondary structure and integrated with the load carrying frames … Given that the ideal temperature for the survival of the experimental subject of our mission, the fungi inside the Science Unit, is around 30 degrees Celsius, the challenge for the Thermal Sub-Team is even greater. Some of the criteria we were faced with are: the Cubesat with Arduino to weigh less than 1.3Kg, have a 10X10X10 cm Cubesat, protect Arduino, sturdy structure, collect data. The total weight of the CubeSat must not exceed 4 kilograms, whereas the the center of mass must lie between 10-15 centimeters from its geometrical center. MAIN FEATURES 1U Cubesat Structure; 6 Deployment switch (Standard) Configurable board stacks PCB stack; Horizontal and vertical stack assembly; Optional shear panels available; Qualified JX-ESPC-101133-B / ECSS-E-ST-10-03; Primary structure mass: 85 g; Stainless steel threaded inserts; Compatible with commercial solar panels and COTS; Wide Z access windows; …
