## A system of ejection CanSat from TuCAN rocket

#### Abstract

This construction is placed in TuCAN rocket witch was designed and build in Rocket Section of Students' Space Association. TuCAN rocket have a goal of branding experiments to a small altitude. This experiments designed in CanSat standard is small construction of the size of a 330ml soda can. They are most often used as platforms in science competition or as technology testers. After reaching the maximum altitude they are thrown from the rocket decks and continue the mission alone. Most often they fall on parachutes or use a anoder recovery system and during the descent they perform a planed program of research or experiment. The described system is designed to secure CanSat during the flight to the maximum ceiling and then release them. The designed system can contain up to 8 experiments on board. Canats can have protruding elements such as antennas and a parachute that can be placed outside the body of the experiment (parachute attached to the can). The containers in which the experiments are located are closed with 2 flaps blocked by pyrotechnic bolts. After shooting the bolts, the flaps open the cargo space and a set of small stretchable rubber pushes CanSats out of the containers. The supporting structure of the system is the case made of aluminum pipe with cut out the necessary holes. It transfers loads during flight and provides a supporting frame for other components. The experiments are placed in elongated gutter containers made of bent sheet metal with welded barriers. The containers are located inside the case and are bolted to it. In the upper part of the system there is a set of pyrotechnical screws and a camera filming the throwing of CanSats. The whole structure is closed with two composite half-round flaps. All mentioned components were subjected to strength analysis. During the design, attention was paid to the ease of assembly and the availability of construction elements. The system was tested during ground tests at the Institute of Thermal Technology. These tests showed the reliability of the structure and made it possible to detect minor defects that could lead to failure of the flight mission. The TuCAN rocket took 2 flights during the Rocket Section polygonal tests. In both cases, the system worked properly, releasing all experiments. During the first firing due to failure of the rocket recovery, the ejection system was destroyed after fall. During the second flight, the slightly modified structure fell safely to the ground without destroying the components.
