Have you ever wondered how boomerangs fly? John Vassberg has. One of Boeing’s top aerodynamicists, Vassberg was at CSULB Friday to deliver one his most popular lectures—one that delves into the aerodynamic capabilities of a hunting tool developed by Aboriginal Australians thousands of years ago.
“It’s turned out to be a cult classic,” said Vassberg, who has given the talk in Paris and Brussels and at Caltech and University of Southern California. “Maybe I’ll teach you something so you’ll have something to do over the weekend,” he told faculty and students at the Spring Technical Seminar.
Boeing Technical Fellow John Vassberg will discuss the aerodynamic characteristics and flight dynamics of boomerangs at the Spring Technical Seminar at noon on Friday, Feb. 23 in the Niggli Conference Center (ECS-312). Students and faculty are invited to attend.
Dr. Vassberg will explain how blade theory can be used to expand upon a basic aerodynamic model developed in the 1960s. The new aerodynamic model is coupled with a gyroscope model for rudimentary analyses. The approach has generated significant findings regarding the radius of a boomerang’s circular flight path, the required inclination angle of its axis-of-rotation, its trim state, as well as its dynamic stability. These discoveries provide a basic understanding of how the interplay between aerodynamic forces and moments, and gyroscopic precession combine to return the boomerang to its rightful owner by way of a circular flight path.

The Long Beach State University College of Engineering has been selected as part of a $2 million statewide consortium to conduct transportation research and workforce development under Senate Bill 1 (SB 1).
If you’d like to send a private Valentine to that special someone this month, Spatial Digital Systems can help.
The Agoura Hills-based company has come up with a technique to embed your message within a separate, innocuous message to shield it from prying eyes. Donald Chang, Spatial Digital Systems’ CEO and President, demonstrated the technique before faculty and students at the IEEE Systems’ Council’s IEEE Distinguished Lecture Friday.
Each year, Long Beach Ballet Artistic Director David Wilcox tries to add some new crowd pleaser to his production of “The Nutcracker”—be it a flying sleigh, a white stallion, on-stage pyrotechnics, or a tree growing before your eyes.
This year, for the company’s 35th annual production of the popular Christmas classic, the extra pizzazz will be supplied by a box created by a team of students led by Long Beach State Mechanical Engineering Associate Professor Chris Beyer.
While an undergraduate at UCLA, Edward Sanchez gravitated toward research. His skill recently shone through at the IEEE 2017 North American Power Symposium (NAPS), where he won a Best Paper Award.
The paper, “Model Predictive Energy Scheduling for a Building Microgrid,” details how to design a control system to coordinate the micropower sources and utility grid demand of a proposed building microgrid. The research is part of a $2.5 million California Energy Commission project to turn the Engineering & Computer Science Building into a Smart Building.

The Long Beach State Department of Computer Engineering and Computer Science this semester will be launching a Colloquium Series to provide a forum for industry best practices and to make research more tangible for students.
Each semester, there will be 4-5 talks by invited speakers from academia and industry, said CECS Assistant Professor Birgit Penzenstadler.
Computer science isn’t just about sitting around staring at code. In Birgit Penzenstadler’s Sustainability Lab, a group of computer science seniors are using technology to help grow vegetables.
All summer long, Ruben Marin, Marinela Sanchez, Jason Plojo, and Lam Tran have been tending their tomato, basil, lettuce, and carrot plants in a lab in VEC, using an Arduino and moisture sensors to develop water-saving techniques. Continue reading “Programming Sustainable Growth”
Reducing emissions from gas grills and pasta cookers. Finding a cost-effective method to detect methane leaks in residential walls. Developing a tool that can return compressed pipes to their original shape.
These were some of the technical problems that students tackled as part of the CSULB College of Engineering’s partnership program with the Southern California Gas Co. (SoCalGas).
“This is a win-win opportunity,” said Hal Snyder, SoCalGas Vice President of Human Resources, Diversity, and Inclusion “Students obtain practical experience, and you’re actually working on things that can help our company.”
The four-year-old CSULB program is led by Rodger R. Schwecke, SoCalGas Senior Vice President of Gas Transmission and Storage. Schwecke, a 1983 B.S. in chemical engineering graduate, said, “It’s great to see these bright engineering students take an idea from concept to physical demonstration, with supporting test data to show results. Ideas such as addressing the ovality of plastic pipe prior to connections, that can turn into commercially viable applications to help our business.” Continue reading “Southern California Gas Company Teams Show Off Senior Projects”
