3 AROUND WORLD STEM AN INTERVIEW WITH A MISSION ENGINEER AT SOLAR IMPULSE. BY PAT SYLVES If you haven t heard of Solar Impulse by now, you ve probably been living under a rock or more specifically, under a rock without a smartphone. The Sweden-based aviation innovation company aims to achieve the first roundthe-world solar flight. Despite some technical setbacks, the team plans to launch their landmark flight in 206. Solar Impulse wouldn t be possible without the hard work of the many engineers, scientists and numerous STEMgineers who support the organization. We sat down with Laila Fathi, a mission engineer at Solar Impulse, to learn more about the amazing things they are accomplishing and how she piloted her own STEM career.

SOLAR IMPULSE NAME: LAILA FATHI TITLE: MISSION ENGINEER EMPLOYER: SOLAR IMPULSE MAJOR: AERONAUTICAL ENGINEERING STEM JOBS: Laila, how did you start your career at Solar Impulse?

4 SOLAR IMPULSE NAME: LAILA FATHI TITLE: MISSION ENGINEER EMPLOYER: SOLAR IMPULSE MAJOR: AERONAUTICAL ENGINEERING STEM JOBS: Laila, how did you start your career at Solar Impulse? LAILA FATHI: I began by studying meteorology at the University of Vienna. After two years of studying, I heard of the possibility to study aeronautical engineering in another city in Austria. I applied and was accepted into the program in During my studies in Austria I visited the Paris Air Show in 20, where Solar Impulse was one of the exhibitors. There I met two of the mission engineers working for Solar Impulse and immediately applied as an intern for the following year. I got the opportunity to join Solar Impulse in 202 as an intern for the Morocco mission. After finishing my studies in 204, I once again joined the team of Solar Impulse as a mission engineer for the round-the-world solar flight. SJ: What kind of career opportunities are provided at Solar Impulse? LF: There are different teams working for Solar Impulse. A technical team, located in Switzerland, focuses on building our solar powered aircraft. They include mechanical, electrical and structural engineers, as well as aerodynamic specialists. Mission Control is based out of Monaco, where mission engineers, meteorologists, mathematicians and a controller focus on mission planning and execution. In regards to the flight, we have two pilots, a logistics team, press team, media team and a ground crew operations team working hand in hand. SJ: What do you love about working with Solar Impulse? Any great memories that stick out in particular? LF: I really appreciate the spirit and the work environment of the Solar Impulse team. I like their vision of making the world a better place to live without exploiting their resources. I also really love airplanes: the aviation industry is creative, innovative and full of passion. At Solar Impulse I got the chance to combine my two passions: aviation and meteorology. Weather is paramount to flying Solar Impulse and I have the chance to learn a lot from our experienced team of meteorologists. Our Pacific flight, especially the moment when the pilot and the team decided to continue the flight from Japan to Hawaii (a 8-hour flight), was a great memory. SJ: What advice would you give to young women looking to pursue a similar career path? LF: It is important not to give yourself a border. If a girl is interested in the aviation industry, even if it s a male dominated career field, she should try and focus on her dream. Even if it gets hard, everything is possible. If you re interested in aeronautical engineering, start flying by yourself, no matter if that includes paragliding, gliding, flying model airplanes or even piloting small aircraft. This will give you a better understanding of engineering, motivate you in your studies and give you the chance to meet experienced people who are working, or used to work, in aeronautical engineering. 8 EARLY FALL 205 // STEMJOBS.COM

5 5-E CLASSROOM STEM ACTIVITY: THE AMAZING JOURNEY OF SOLAR IMPULSE Here are some ideas for how middle school teachers could use this story as a launching point for integrated STEM learning. Our activities follow the 5-E Learning Cycle Model. Part : Engage Ask students: Do you think a plane could be powered without using any fuel? What alternative forms of energy could a plane use? How fast do you think such a plane could go, and how would it need to be designed? What would it be made out of? Ask the students to imagine a plane powered entirely by the sun a star almost 93 million miles away. Does this seem like it would be possible? What would be some of the challenges that would need to be overcome? What would be some of the constraints of this type of plane compared to the planes we are used to flying? Have students watch the video about the Solar Impulse program that can be found at teacher-resources. Have students read the STEMJobs article about an interview with one of the mission engineers involved with the Solar Impulse. Ask the students: What are the different types of team members and expertise that would be needed to plan an undertaking like the Solar Impulse flight? What concepts from science, technology, engineering, and mathematics do you think these team members would need to know about? Part 2: Explore Divide students into groups of 4 and have each group member choose one aspect of the Solar Impulse mission they want to specialize in. The choices are: a. Navigation Specialist This person is responsible for researching the route the Solar Impulse is taking around the world. They must create a table that shows the distance covered by each leg of the journey, how much time the Solar Impulse took or should take to complete that leg (using historical data on average speed if necessary), and its speed for that leg. They should estimate the Solar Impulse s average speed, total distance, and total time for the whole trip. Recommended resourcescan be found at b. Flight Specialist This person is responsible for researching the relationship between lift, drag, and weight as an object glides, as well as the force of thrust, and how this relates to Newton s First Law. Their goal is to build a diagram of the forces acting on the Solar Impulse. Recommended resourcescan be found at NOTES STEMjobs.com The Amazing Journey of Solar Impulse

6 2 c. Aeronautical Designer This person is responsible for researching how the Solar Impulse was designed, and for drawing a simple scale model of the plane. They should be able to explain why certain design decisions regarding wingspan and materials were made. One way they could demonstrate these tradeoffs is by working with the flight specialist to construct several paper airplanes that illustrate key components of aerodynamics that went into the design of the Solar Impulse (e.g., large wingspan, light weight). Recommended resources can be found at d. Environmental Impact and Feasibility Specialist This person is responsible for researching whether solar powered flight is feasible for reducing the impact of humans on the earth, what challenges still need to be overcome, and whether and how the flight of the Solar Impulse is significant to our society. They should come up with a bulleted list of benefits and challenges of solar-powered flight. Recommended resources can be found at The teacher should circulate and assist student groups as they are conducting their research, encouraging them to work together and get help from each other. Part 3: Explain Have students present the results of their research to the class. Focus the class on the new information that each presentation provides, as well as on the important STEM concepts described above. Let students know that the purpose of their presentations is to get feedback and see others work so they can create a quality product in the next stage. Part 4: Elaborate Tell students they now will be extending their research in their same groups: Today, your group will be creating a poster to display at our school to inform the student body, teachers, and staff about the importance of the Solar Impulse flight. The poster will have 4 sections on it, and all group members must work together on all four parts: Part : Map of Route: The poster must include a map of the route the Solar Impulse took, with distances, speeds, and travel times. The poster can also include, if time allows, an imaginary route for the Solar Impulse created by your group, where it visits cities and locations you ve always wanted to visit. Part 2: Forces Acting on Plane: The poster must include a free body diagram that describes the different forces that act on the plane as it is in motion. Part 3: Design of Plane: The poster must include a fully labeled scale drawing or a photograph of a scale model of the Solar Impulse with a short description of why certain design decisions were made. Part 4: Feasibility: The poster must include a conclusion where you discuss why the Solar Impulse mission is important and the challenges still to be overcome. 2 STEMjobs.com The Amazing Journey of Solar Impulse

7 Part 5: Evaluate Have students individually look at each group s final posters during a gallery walk. Then have them write an entry in their science journals where they critique their own poster as well as the posters of two other groups. Specifically, they should answer: How did this poster provide important information about concepts from science, technology, engineering, and mathematics? What could have made this poster more informative and educational to its audience? NOTES 3 STEMjobs.com The Amazing Journey of Solar Impulse
