Coheteros

Coheteros Association

Are you looking to anticipate the space future of Seville? Gain experience in the field of experimental space coheteria? Feel the roar of rocket engines or witness shocking throws? So this is your association.

In Coheteros there are many large projects, which position them as a reference association in Andalusia. They have the ability to design, develop, manufacture, rehearse and launch their prototypes of experimental space pitchers thanks to their more than 15 years of experience in the sector. In fact, its main objective is to extend knowledge beyond the theory, put into practice the knowledge acquired during university studies and materialize all this in real projects capable of fulfilling the established mission.

Although chemical fuels are used in coheteros in the rocket engines, what really moves them is passion, illusion and union. All its members, although with different tastes, disciplines or hobbies, share the same illusion for space pitchers and the technology inherent in them.

Likewise, certain members of the Association are former students of the University of Seville with real experience in the sector, which allows to use work methodologies typical of the business world, experience based on experience, develop complex and reliable tools, but above all to establish a direct route between the university and the labor world, and open the doors to those members of coheteros who wish to devote themselves to the space sector, which will undoubtedly suffer a boom scale.

Another of the purposes pursued by this association is the participation in Euroc (European Rocketry Challenge) The first European competition of experimental pitchers in which teams from the main European universities meet. To do this, Coheteros works to adapt their current pitchers for employment in said competition.

Finally, Coheteros is within the Seville Space Forum, a group of public, private entities and associations that seek to extend the passion for space in Seville. For this, many activities related to this area are proposed annually. In particular, Coheteros performs bank trials, general dissemination talks and more specific and experimental coheteria workshops among others.

Goals

Extend knowledge about space modeling, experimental pitchers and all its subsystems. To achieve this, Coheteros is immersed in all associated engineering facets: propellants, design, engineering, recovery systems, electronics, aerodynamic design, etc. Always with the aim of using the least possible number of cots and betting on the engineering and design of the equipment.

Another objective of the Association is to participate in the EUROC competition and demonstrate the capacities of the designed experimental pitchers, guaranteeing that CMPLE with the objectives and mission of the competition.

However, the main objective of Coheteros is to create a united team that shares the illusion and passion for the world of rocket, as well as preparing all its members for the world of work, getting them to become professionals in the sector, taking advantage of the theoretical basis that are taught in the university and merging them with real experience in ambitious projects of great size.

Organization

Coheteros is organized in 9 work areas:

- Systems Engineering: Area responsible for the management of the requirements, as well as the conceptual design of much of the pitcher's systems.

- Propulsion: Design of the propulsive, ignition systems, propellants employees and geometries of the grains.

- Structures: Area responsible for guaranteeing structural integrity The pitcher, interfaces and subsystems during any operation of the pitcher included in the flight envelope

- Guided, navigation and control: It takes care of all the engineering behind the actions of the pitchers, maneuvers, management of the sensors and the rejection of disturbances in flight. It is also the area responsible for developing the flight simulator of the pitchers and predicting their behavior

- Electronics and Telematics: It is responsible for the development of all electronic on -board systems to obtain flight data through sensor selection, tracking, loose recovery subsystem commands, video record, power supply, acting subsystems, etc.

- Software: In this area, the entire generation of codes used in the projects is included: on -board codes for the pitchers, states machine management, graphic interfaces for visualization of telemetry data, bank tests or test support. Its main function is to ensure that the work carried out by CNG is implemented in electronics developed by the electronics and telematics area

- Aerodynamics: area in charge of aerodynamic design of all the surfaces of the pitcher, optimization and generation of semi -time and CFD aerodynamic models to use them in the flight simulator. They are also in charge of aspects such as stability, maneuverability or design of recovery subsystems.

- Design: It is responsible for making the design and assembly of all subsystems, components or elements that make up the pitchers. They are also responsible for providing the rest of areas of geometric and mass models of the pitcher, essential for their activities.

- Manufacture and tests: This area encompasses all previous areas and it establishes all activities related to manufacturing, testing, tests and tests to guarantee the proper functioning of the systems developed.

Projects

- Betelgeuse: Experilizable Experimental Rocket of solid propellant with the ability to reach 600 m of passive apogee and stabilization.

- Naos: Experimental solid propellant rocket with the ability to ascend to almost 3 km of apogee, passive stabilization and that has various subsystems (release and recovery subsystem, video record on board, flight data, tracking and telemetry data)

- Naos Evo: evolution of Naos that incorporates new and more robust subsystems, as well as an innovative active control subsystem that will allow rejecting disturbances during the flight.

- 10 km Apogeo pitcher : This is the most ambitious project carried out by Coheteros and that aims to position the University of Seville as the first in Spain to achieve the manufacture of an experimental university rocket of solid propellant with 10 km apogee (stratospheric). To do this, all technologies developed in NAOS EVO will be used.

Security measures

To guarantee the safety of its members and operations, in Coheteros they strive to mark clear security protocols and up to date with all the necessary permits to carry out all the activities that may have a certain level of risk. Among these measures are:

- Work protocols and manipulation of flammable substances

- Petition of launch permits (Notam) and transportation

- Civil Liability Insurance

- Safety, manufacturing and manipulation courses

- Experts in each subject with previous experience that look for the safety of the team

- Organization, role of roles, checklists and specific tasks both in bank trials and launches

- Association's legal support
