MAE Students Win 1st Place at the Intercollegiate Rocket Engineering Competition in Green River, Utah

The MAE team for ESRA (Experimental Sounding Rocket Association) won a 1st place overall award this year at the 4th IREC (Intercollegiate Rocket Engineering Competition) in Green River, Utah. The competition involved a team of four students who designed, built and flew an experimental sounding rocket designed to carry 10 lbs. of payload to 10,000 feet AGL. The rocket was built entirely from scratch in one of the member’s garage using cardboard mailing tubes, birch plywood and aluminum. We also built our own electronics package with a custom coded deployment sequence that worked flawlessly in controlling drogue, and main parachute deployment using a combination of three accelerometers, and a barometric pressure sensor. Although we were not the only team to design and build our own flight computer, we were the only team with enough guts to use it as our primary flight computer! we used the commercial computer only as a backup! Scoring for this competition was based on how close our apogee was to 10,000 feet, an oral, and written presentation and general knowledge of the rocket systems specific to our rocket.

We flew a payload designed to visualize flow over the nosecone. we had a clear acrylic body section that had four tufts of yarn glued on. A camera mounted in the nosecone viewed the yarn with four mirrors mounted at a 45 degree angle. the results were great! we had very little flow separation below the nose and were able to get a roll rate from the rocket by using the sun as a reference point.

The Results of our efforts: Our calculated burnout velocity of mach 0.77 was confirmed from the data Our unpowered drag estimate for the rocket was far too small, causing our calculated apogee to be much higher than the actual apogee.

The Parachute deployment sequence was flawless, using a new novel deployment device, that to our knowledge has not been tried before in the field of sounding rockets. (the ideas were borrowed heavily from skydiving parachute systems) The team members: Tim Baker – Design and fabrication Takahiro Morikawa – Aerodynamics and fabrication David Murakami – Trajectory analysis, flight software, electronics and fabrication Adam Vore – Design, fabrication and recovery system Advisors: Charely Hoult Dave McCue

CSULB student fulfills dream as NASA intern Student receives a summer internship that jump-starts her career

Anusha Prabhakar

Cal State Long Beach aerospace engineering student Anusha Prabhakar recently won the second annual American Institute of Aeronautics and Astronautics (AIAA) summer internship program. Prabhakar, a senior at CSULB, is already working at her internship and will spend eight to 10 weeks at the Ames Research Center in Moffett Field in Edwards, Calif, assisting in several NASA experiments. “Working for NASA has always been my dream and ultimate goal in advancing my aerospace career,” Prabhakar said in an e-mail. “And now that I have this wonderful once-in-a-lifetime opportunity, I hope to learn as much as I can, and this internship in turn will enable me to better understand what I would like to pursue later on in my career.” AIAA is the world’s largest technical society dedicated to supporting students pursuing a global aerospace career. They partnered with NASA to develop the new generation of aeronautical engineers.

Neal Barlow, AIAA’s vice president-elect and chair of its student activities committee, said in a press release, “NASA’s internship program will provide her with an engineering experience that only it can provide. We are pleased to be partnered with NASA and their continued efforts in developing the next generation of aerospace engineers.”

Prabhakar is the chair of AIAA at CSULB and served as the chair for the 2009 Region VI Student Conference, which was held in Long Beach. “These positions involved considerable organizing and leading a group of students to host the annual regional aerospace conference at our university,” Prabhakar said. “CALVEIN encouraged working in a team environment, and learning as much as possible not only by observing fellow students and professors work, but also helped in gaining actual hands-on experience.” The event was very successful and Eric Besnard, a professor in the mechanical and aerospace engineering department at CSULB, said in a press release, “Anusha is the type of student who will make a great manager in industry. That was apparent in her role in the AIAA student chapter and especially as the main person behind the success of the AIAA Region VI Student Conference hosted at CSULB this year.”

Prabhakar previously had an internship with The Boeing Company, where she worked on detailed drafting assignments on the center wing section of the 747B and was also a part of the C-17 Stress Analysis Group. Prabhakar is also a part of CSULB’s California Launch Vehicle Education Initiative. She went through the procedure of developing, testing and launching low-cost, liquid-propelled rockets. Prabhakar plans on graduating with a degree in aerospace engineering in spring 2010.

Besnard Receives 2009 Faculty Adviser Award from AIAA

Eric Besnard

Eric Besnard, a professor in the Mechanical and Aerospace Engineering Department at CSULB, has been named the recipient of the American Institute of Aeronautics and Astronautics (AIAA) 2009 Faculty Adviser Award.

The award is presented to the AIAA faculty adviser of a chartered student branch who, in the opinion of student branch members and the AIAA Student Activities Committee, has made outstanding contributions to his/her students in local, regional and national activities. Besnard was also selected to receive the honor due to his passion for aerospace and his ongoing efforts in encouraging students in the field through hands-on projects.

“The rewarding part about being chapter adviser for the AIAA is working with the students to help them transform ideas into an engineering system they can test,” said Besnard. “The quality engineering department at Cal State Long Beach also helps make this possible. It is very well recognized in Southern California, with graduates in demand for local aerospace companies and are very capable of competing nationally.”

Besnard, who has taught upper-division aerospace design and space systems engineering at CSULB since 1995, was presented the honor during the 47th annual AIAA Aerospace Sciences Meeting Award Banquet in Orlando. Teaching undergraduate and graduate students, Besnard’s schedule also includes senior design classes, spacecraft systems engineering, and rocket and spacecraft propulsion.

Much of the “hands-on” work Besnard has been recognized for by the AIAA is for the California Launch Vehicle Education Initiative (CALVEIN), the rocket program on campus that includes several projects involving AIAA. As head of CALVEIN, he helps students design, build and launch large rockets, each with its own unique characteristics.

“I am proud to be recognized by this premier aerospace professional organization (AIAA) for the job we do at CSULB in preparing the next generation of aerospace engineers by having them involved in hands-on projects, an approach that requires departmental commitment and resources,” said Besnard. “The IMU (inertial measurement unit) we now use on some of our test flights was purchased as part of a student project that was funded by the Los Angeles professional section of AIAA. Another project deals with the development of a wind-sensing package to be used for rocket launch operations.”

The students involved in the wind-sensing project took second place last year when they presented the work at the AIAA 2008 Region VI Student Conference at Arizona State University. Students Faisal M. Buharie and Samir Mohamed won the award in the undergraduate category for their new wind sensor, which may be used during launches to measure the prevalent wind at altitude. Oscar Mejia, another undergraduate student in aerospace engineering, presented his project titled “Trajectory Simulation for CSULB Sounding Rockets.”
