RAFALE II 2016-2018 Catamaran class C THE OBJECTIVE The Rafale II project was born in the continuity of Rafale I. The objective was to design and manufacture a second class-C catamaran, in the school of higher technology and to be more efficient than the first. It was therefore necessary correct the defects of Rafale I: rework the various elements of the boat to reduce the mass, improve buoyancy, the rigidity of the hydrofoils, and rebuilding the damaged rigid wing in order to obtain a much more efficient vessel. SHELL The volume of the Rafale I hulls had been deliberately limited in order to reduce their weight as much as possible. The boat being made to fly, its flotation had been put in the background. However, to take off, the boat needed to reach a speed of at least 10 knots. At low speed, the waterline being low, the crosspieces connecting the two hulls tended to hit the waves and consequently to slow down the ship : which is problematic in an acceleration phase necessary for take-off. ​ A second problem present in many catamarans: the lack of volume at the front of the hulls. The boat then had too much of a tendency to sink, that is to say nose dive and sink into the sea and turn around. Rafale II's main mission was therefore to respond to these problems related to the buoyancy of the hulls. Significant design work has been carried out: increase the volume of the shells in order to float higher and no longer get into the oven. ​ In addition, the structure of the boat lacked rigidity according to the skippers. There was particularly too much play between the transoms and the hulls. It is known that the rigidity of a boat goes hand in hand with its ability to relaunch and accelerate. Thus, Rafale II had to be more rigid than the first prototype in order to improve its performance. ​ To answer these problems, and, always with a view to reducing the total weight of the boat, the students worked on a new design and oriented on the use of prepreg aircraft-grade carbon fiber. Heating molds have been designed in order to be able to manufacture the hulls. Which was a real step forward in materials technology, because in comparison Rafale I had been made from dry carbon fiber infused with epoxy resin. The new structure has made it possible to reduce the mass of the shells by 10% while increasing the volume and the rigidity. FOILS Although efficient, the foils of the first prototype were too heavy. They have been manufactured with resin-infused dry fiber and foam reinforcements. The foils of Rafale II had been redesigned to improve their performance and above all reduce their weight. Thus, as with the shell, the pre-impregnated fiber has summer chosen linked to a reinforcement 3D printed: which allowed a significant reduction in mass and an improvement in overall rigidity. THE WING The Rafale I wing was very heavy. The mast of its structure had been made from a lamp post to reduce costs as much as possible, while having a conical shape specific to boat masts. The club therefore had the idea of designing a new wing, more efficient and above all lighter. However, the realization of this project never came to fruition. Thus, Rafale II is still sailing today with the Rafale I wing. The competitions Unfortunately, the competition which was the real raison d'être of Rafale II, La Little Cup, disappeared in a few months, despite having existed since the 1970s. Thus, the C-class catamaran Rafale II has never been able to shine in fleet races with similar boats. However, Rafale II was still able to shine in 2 events: -Miami Foiling Week (February 2018) ​ Present at the Foiling Miami Weekend 2018, Burst It surprised sailing enthusiasts and curious passers-by with its imposing size. The catamaran respects the few rules of class C: 25 feet long, 14 feet wide, and 300 square feet of sail. These dimensions make class-C the largest coastal cruising catamarans without a cabin. Each hull displays the surprising weight of 43 kilos. During the construction of the ship, the fifteen students of the Rafale ETS team sought to save weight, gram by gram, to meet audacious objectives. Innovative techniques have been developed in order to respect the mass limits, such as the insertion of a 3D printed honeycomb core between the layers of carbon. The catamaran, however, being the only multihull on the water at the Foiling Miami weekend. It is therefore impossible to compete with someone similar. In addition, the manufacture of the foils had not been completed in time. The team was nevertheless proud to unveil for the first time on the water a prototype that had taken one year to design and one year to manufacture. So before flying it we just sailed it. Speeds of 13 knots in breeze at 15 nds have been reached without hydrofoils. The team came back from this week of sailing with the boat broken at certain points, but happy with this experience. She had worked hard every night to make the boat operational for each new day. It took an average of 3 hours of repairs for 1 hour of navigation. The team then concentrated on making the ship more reliable with a view to winning future regattas. At the same time, the club contemplated to develop its support: the manufacture of a 25-foot catamaran with hydrofoils required significant resources, and few universities were ready to embark on such a project. To tell the truth, the ETS was the only one to provide the necessary budgetary and logistical means. -Montreal Open C-Class regatta (September 2018) ​ From September 6 to 9, 2018, regulars on the shores of Lake Saint-Louis probably noticed at this time two large vertical wings looming on the horizon. The founder of the shipyard Vanguard, Steve Clark, and the Rafale student club from the École de Technologie Supérieure clashed during a friendly regatta, the Open C-Class Regata, thanks to the investment of former members. ​ Both catamarans were cut out for racing: both equipped with hydrofoils and wings rigid for propulsion. The two catamarans pulled tight tacks while pursuing each other at 22 knots in a sustained wind at 12 knots. During one of the close-hauled legs, the Rafale team recorded a speed of 33 knots. This is the first time, after three years of construction, that Rafale II was flying. ​ All the same, the game was not easy for the students: the American ship Cogito distanced himself from Rafale II at the end of each round. Poor hydrofoil adjustment prevented the latter from stabilizing its flight altitude and accelerating to the expected speeds. The ship would rise about twenty centimeters above the water and then fall back, while its American counterpart skimmed the surface during continuous flight edges. After all, the important thing is to fly and slow down as little as possible. ​ The excessive speeds obtained weakened the pivot points of the rudders and the tearing of one of them. Throughout the night, the students were busy installing a new steering support. The ship was again ready to sail the next day. Despite a few lost rounds, the overall performance of the ship has demonstrated good maneuverability and flotation (such as resistance to being buried in the oven), all in a steady wind.

APRIL SUM-UP With April, Rafale is blooming. Two months left before competition and, with the beginning of spring, the team begins to achieve of its projects and go through smallest ones: ​ 🖌 DESIGN ​ Achievements: The design of the hull of Rafale 4 is now finished with the general look confirmed and only few details remaining. Drying tests of flax fibers have been performed to study the effects of humidity in our workshop on the performance of the composite. The design loads for the structure analysis of the hull of Rafale 4 are now known and the positions of the elements (rigging, foils, wings) are chosen thanks to the DVPP previously developed and a balance analysis of the boat in different configurations. Work in progress: The finite element analysis for the hull of Rafale 4 has progressed well. Some reinforcements still need to be placed but we will soon know how the composite will be made for the different parts of the hull. A project about the design of Rafale 4 foils has been launched. More to come. Future goals: Next great step for Rafale 4 will concern the hull’s mold design and manufacturing followed by the latter’s infusion. MicrosoftTeams-image Design of the hull of R4 with Quentin MicrosoftTeams-image (1) Finite element analysis for the hull of Rafale 4 with Quentin Conception et design avec Martin et Quentin Conception et design avec Martin et Quentin MicrosoftTeams-image Design of the hull of R4 with Quentin 1/3 🛠 MANUFACTURING Achievements: The new wings made with flax fiber and thermoplastic PMMA resin are now fully infused and sanded. It took some trials and errors and a lot of time to build them since it is really complicated to place the flax fiber on the complex geometry of the wings and to apply vacuum without making critical folds for the structure. A trolley has been built to facilitate the displacements of the boat on the competition site. Work in progress: The finite element analysis for the hull of Rafale 4 has progressed well. Some reinforcements still need to be placed but we will soon know how the composite will be made for the different parts of the hull. A project about the design of Rafale 4 foils has been launched. More to come. Future goals: Next great step for Rafale 4 will concern the hull’s mold design and manufacturing followed by the latter’s infusion. R3.5 and wings R3.5 and wings Infusion of the wings with Martin and Ronan Infusion of the wings with Martin and Ronan R3.5 and wings R3.5 and wings 1/5 💻 EMBEDDED SYSTEM ​ Achievements: This month a printed circuit board has been designed and sent to be printed for the load sensors. This board acts as a sort of motherboard for the whole sensor’s electronics and facilitates its integration into the custom casing. Work in progress: The load sensors still require a few code adjustments and the assembling of the previously mentioned circuit boards, and they will be fully ready. Work is still ongoing to adjust and make the database and the data viewer software more reliable as well as integrating the wind meter into the data flow. Future goals: The long-term goals for the embedded system stay the same, in essence looking towards what the system can bring to the team for Rafale 4. As for short term goals, having a working wind meter, and splitting up the GPS module from the main hub are the more important ones, and are already in progress. pcb_load_sensors pcb_load_sensors Système embarqué avec Christophe-André Système embarqué avec Christophe-André pcb_load_sensors pcb_load_sensors 1/2 📞 COMMUNICATION ​ ​​ Achievements: Rafale celebrate its 10Th birthday on the 21st April. In the program, an overview video of all the work achieved during ten years from the Class-C catamarans to the foiling moth, a presentation of the club by our captain, talks with our guest and the highlight of the show: the unveiling of our new wrap with a teaser video. We would like to thank all the guests for coming and everyone who participated in this event. In parallel, continuous communication has been done with the March Recap and Blog Post for the competition. Work in progress: This month, a lot of work concerning the preparation and logistics for the competition are in progress thanks to our sponsors. Meeting were made with Voile Sansoucy to discuss and brainstorm the creation and manufacture of custom trampolines for our new ladders. Then, GE Hydro is helping us for the transportation of the boat to Italy. The end of design and manufacturing rhymes with the writing of the technical report required for the competition and its accompanying video summary while a huge communication media preparation is happening until June. Future goals: Preparing the team for technical and social networks competition will become the main task in the future weeks as well as teambuilding and formalizing all the logistics related to the trip with the help of some of our sponsors. 10TH RAFALE Rafale family New design for the birthday New design for the birthday 10TH RAFALE Rafale family 1/5 🧭 NAVIGATION ​ Achievements and work in progress: Since R3.5 design became fixed, the rigging team gathered to discuss, imagine, and prepare the 2023 setup. Following this, some preparations and some slicing were made to be ready to install everything on the boat when the wings are finished. Future goals: The future goal would be to install and adapt the different parts of our rigging to our new wing and to our new sail to ensure the best performance. All of that will happen in the last stages of the manufacturing phase of our project. This phase will be a great occasion to ensure knowledge transmission between beginners and experts of rigging in the team and to train the team for boat setup during SUMOTH 2023.

RAFALE I 2013-2016 Catamaran Class-C Made up of engineering students from the École de technologie supérieure de Montréal, it was in September 2013 that the Catamaran Class-C ÉTS project was launched with the aim of designing, building and sailing a state-of-the-art sailboat. The objective is ambitious: to participate as the first student team at the prestigious Little Cup of America. The team successfully rose to the challenge, taking part in the 27th Little Cup, in Geneva, Switzerland, in September 2015. Rafale's performance amazed many and attracted cameras from all over the world! Rafale ÉTS earned sixth place in the championship, the Spirit of the Hydros Foundation award, as well as the title of Sailor of the Year 2015 from the Fédération de Voile du Québec GOAL Our ambition was to compete with experienced teams. We were the only students in the circuit, the other teams being professional and sometimes having a budget of several million dollars. The hard work delivered by the members of the project allowed us to present a competitive boat to the Little Cup 2015 . We were not only the first Quebec team to participate, but also the first university team to present such a project. ​ Rafale Class-C is an impressive, innovative catamaran, mounted on hydrofoils and equipped with a rigid wing. The boat was built with a minimal budget and entirely on a volunteer basis, which greatly sets our team apart from others. Marc Farmer and Trevor Parekh, the navigation team, managed to lift the team to sixth place in Geneva. We were also named Sailor of the Year by the 2015 Sailing Federation and won the "Spirit of the Hydros Foundation" award. CLASS-C The C-Class has been around since the 1960s. It is one of the most innovative nautical categories. The boats are catamarans measuring 25 feet in length and 14 feet wide. They have the reputation of being among the fastest boats on closed circuits (“Inshore”). Thanks to the very succinct and permissive regulations, they are also at the origin of many innovations in the field of sailing, in particular the wing masts and the rigid sails which have been the symbols of the class for a very long time. Since 2011, they have also been behind the development of hydrofoils for multihulls.
