Design and Development of Sohaidas Bio-payload Recovery Cansat

In this paper, the detailed design and fabrication ofSohaidas cansat which has a bio-payload recoverymission and the interaction between its subsystems andtheir functions are explained. In this mission the payloadis an uncooked egg that must be healthy during themission. This cansat has two segments, payload andcarrier segments. This two segments must separate fromeach other when the cansat height reduced to ۱۰۰ metersfrom the earth's surface. We introduces a new reliableand fast release mechanism in this cansat. It can alsogather the information such as content of O۲ and CO, thevelocity and acceleration in three axis, pressure, andtemperature in payload segment. Inside of carriersegment it has been placed the telecommunicationsubsystem, C&DH۱, release mechanism and a GPSmodule. A camera is placed in carrier for taking photoand video from the egg to monitor its healthy and arecovery subsystem is applied in each section to controlthe velocity of descending which should be less than ۵m/s. A memory card is installed in carrier segment tosave any data before transferring the data to the groundstation. Finally, the results of experiments prove theeffectiveness of the design of the new releasemechanism, the container which is made of compositematerials for payload and the payload segments.
