Design of a Composite Structure of a Cube Satellite from the Aspect of Heat Transfer and Distribution And Thermal Stresses in GEO Orbit using Genetic Algorithm
, M.Sc. Thesis Sharif University of Technology ; Abedian, Ali (Supervisor)
Abstract
This project aims to design and optimize the structure of a thermal observation cubesat utilizing a multi-component carbon-silicon carbide matrix composite material with a 40% volume fraction for both the frame and panels. The employment of this material results in a 23% weight reduction compared to aluminum, which can be utilized to enhance the satellite's payload capacity. The target orbit for the satellite is GEO, which is approximately 36,000 kilometers from Earth. These satellites are positioned in the sky such that their orbital period matches the Earth's rotation, causing them to revolve around the Earth once every 24 hours, effectively making them appear stationary from a specific...
Redesign and Analysis of Deployment Mechanism for an Antenna on a CubeSat
, M.Sc. Thesis Sharif University of Technology ; Alasty, Aria (Supervisor) ; Vossoughi, Gholamreza (Supervisor) ; Talaeizadeh, Amin (Co-Supervisor)
Abstract
The use of deployable antennas has grown significantly in space systems due to their capability to be stowed within launch vehicles and achieve high gain. These mechanisms must feature low structural complexity, low mass, a large effective aperture, compact stowed dimensions, and sufficient strength and stiffness to prevent frequency resonance during launch and withstand stresses imposed by the launcher. This research aims to design a deployable mechanism capable of forming the parabolic surface of the antenna with higher precision and simplicity while meeting launcher requirements. After reviewing existing mechanisms and deriving mission and space requirements, the antenna design...
