Less Weight = GO FAST

On November 7th 2019 The SAWE San Diego Chapter partnered with San Diego State University’s Formula SAE (Society of Automotive Engineers) team Aztec Racing to host an university outreach event. SAWE San Diego President Brian Wang gave a presentation on an overview of mass properties engineering and the SAWE while students were treated to pizza and refreshments provided by the chapter. The event was a huge success and was received well by a packed room of enthusiastic engineers that are pursuing degrees ranging from mechanical, aerospace, electrical, biomedical, and many more! After the presentation a Q&A session was held where students and chapter members were heavily engaged discussing topics ranging from career experience to how can Aztec Racing be more weight conscience in their 2020 design. Following, SAWE San Diego presented Aztec Racing with a hard copy of The SAWE Weight Engineers Handbook to add to their library and also encouraged students to join SAWE to receive the many benefits provided for free! Finally a generous tour of Aztec Racing’s garage shop was conducted by President Dani Phan and Chief Engineer Austin Hoang. Many questions were asked from how can the team validate the 2020 car’s weight, CG and inertia while chapter members were able to discuss possible solutions. The SAWE San Diego Chapter is currently in discussions on formally supporting Aztec Racing in an advisory role.

Aztec Racing Formula SAE Team is a 501(c)3 non-profit student-run organization at San Diego State University.  Formula SAE is an international collegiate design competition focused on a student designed and manufactured open wheel race car. Every year the team is tasked with raising funds to design, build, test, and compete nationally against competing collegiate teams.

LA Chapter Meeting & SAWE Training Success Story

On October 23rd, the LA chapter met at Don Ramon’s In Huntington Beach to hear Doug Fisher give an encore presentation of his SAWE international talk of paper #3729, Application of SAWE Course “Developing Basic Parametric Methods” To Nacelle Weight Estimating. After enjoying the delicious Mexican food and some business about how great the upcoming conference will be (but, hey, that’s another blog post), Doug started his presentation after some minor technical difficulties.

Doug began by explaining what his approach to weight estimating before he took Andy Walker’s Developing Basic Parametric Methods class. He would plot his variables, he would get his equations, but he would not know how realistic or precise the information is. Andy’s parametric class gave Doug the knowledge to not only find a parametric relationship between variables, but the statistical tools to extract whether a relationship is real or coincidence and the uncertainty in his mass estimates. As Doug explained in his paper, “Providing a weight number is not enough. A justification of the weight estimate, backed up by a sound methodology that created that estimate, is critical in the understanding of risks associated with committing to the weight estimate.” Now Doug has the numbers and backup he can take to management. As Andy Walker remarked about Doug’s experiences, “it (SAWE training classes) means we’re having a direct, measurable, and positive impact on the decision-making process.”

Happy Veteran’s Day!

Today is Veterans Day in the US.  Every Veterans Day I call my brother and tell him he’s still my favorite veteran.  He served as a US Navy pilot for many years, flying the Lockheed P-3C Orion all around the world, mostly out over the ocean on long endurance missions.  His interest in aviation is a big reason for my interest in it as well.

On behalf of SAWE, I want to thank all former and current military personnel for serving your country.

This special group of patriots to their country are high end users that push products we support to their limits while putting their lives on the line.  Mass properties engineers’ humble role in ensuring safe, efficient, and reliable operations of these products helps them do their job. Whether military or commercial, this role applies to all products we support throughout industries worldwide.  

SAWE has a continuing responsibility to a worldwide community of end users to ensure mass properties engineering has the best resources available to do their jobs.

SAWE Houston Offshore Workshop 2020

The Houston chapter of SAWE and the Offshore Industry Committee invite you to attend HOW 2020. The Houston Offshore Workshop will focus on maturing working drafts of two SAWE Recommended Practices on Weight Reporting and In-Service Weight Control, Mass Properties Engineering Handbook chapter for the Offshore and the critical concepts needed to be a Certified Offshore Mass Properties Engineer by SAWE. The event will be held at Fluor conference facilities at their corporate offices in Sugar Land (20 miles Southwest of Houston), Texas, in March. We invite all Weight or Mass Properties Engineers, Students, Exhibitors, Class Societies, Government regulators to attend the meeting. The meeting fees will just cover meals and will be free to University students, since we appreciate the time you will spend supporting our development efforts. We welcome volunteers to help with the technical content and planning the work shop. Contact a Houston chapter officer or the Offshore Industry Committee chair. Further details will follow on the SAWE.org webpage and through this Blog system.

Group Office: File Locking and Version Control

Group Office has proven itself to be immensely useful to me, for chapter activities, for document development and as a source of some of the more obscure or perhaps just time pertinent material. (If you’re running a conference you’ll really appreciate it !) One thing not commonly shown is how to have a configuration controlled document, edited sequentially by a group of people. There is a locking feature used to maintain control while you are editing the document. Along with the file version viewing capability, document editions are maintained as properties of the single document name to keep your group office space nice and tidy. See: Group Office Landing Page and scroll down to “File Locking and Version Control”

Successful Conference Planning Meeting in Hamburg

The European Chapter host committee has selected an excellent venue for SAWE’s 79th International Conference. We’re very excited to share the charm, ambiance, and hospitality of the Privathotel Lindtner at the conference next May. It’s a beautiful facility, has great meeting room accommodations, and the food is amazing.

The Executive Committee was represented on site by President-John Hargrave, Executive Director-Bill Boze, and Senior VP-Errol Oguzhan. In addition VP Technical-Robert Zimmerman, VP Internet-Greg Ray, Executive VP-Clint Stephenson, and Financial Chairman-Fred Brown supported via Zoom Telecom.

This meeting was held Saturday, Sep 28th at the conference hotel site. It was a full day of event planning, facilities tour, schedule coordination, and budget planning. It was hard work, but the result is a fantastic SAWE Conference experience for you next May. Make your plans now to attend and follow the announcements on SAWE.org for more details.

On Monday Bill, Errol, and John were invited by Kim Mittler to address the Airbus mass properties group about SAWE.  The meeting was a great opportunity to meet additional mass properties engineers and to discuss benefits and activities of SAWE membership.

SAWE using ZOOM for online meetings. And you can too!

As some might have become aware, SAWE is now using a conferencing app called Zoom. We’re encouraging everyone to use this for SAWE meetings over Join.me or any other service. SAWE has purchased a pro license with 2 host accounts that will allow unlimited time and up to 100 people in an online meeting. Bill Boze is the main admin for this and can assign host role as needed.

However you don’t need to depend on Bill to schedule meetings or ask to host a meeting. There is a free version open to everyone with all the same features as the pro license, except the meeting length is limited to 40 minutes. The work around for this is to plan back to back meetings if you expect to need more time. If you want to hold a 1 on 1 meeting to screen share something, there is no time limit. If you have a need to host a recurring meeting for SAWE business, contact Bill to get something scheduled.

Go to zoom.com to try it out and sign up for an account. We did some testing before making the switch from Join.me and found that Zoom will work behind most company firewalls. There is a downloadable Zoom app for computer and mobile devices that will provide the best full-featured experience. If you can’t get the app installed the web based version should also work without issues.

I’m attaching some notes that Bill compiled on using Zoom. Some of these notes apply only to the advance features on the Pro license but still good to look thru. Give this tool a try and leave any feedback you might have in the comments.

SAWE Academic Liaisons

At the last Society of Allied Weight Engineers Board of Directors meeting, Dr. Donna S. Gerren, our VP SAWE Academic Affairs, proposed SAWE establish Faculty Liaisons with university and college professors. The rationale for doing so were:

• We are still very weak in our position to gain a foothold with the college community. The reasons are many but the first and foremost is that our discipline is not recognized at the college level. This must be addressed. We continually touch on it but in reality, have made little progress.

• Creating a Liaison position may be the first step in getting some help from within the colleges to assist in moving forward toward the creation of curriculum that can be introduced as an elective course in Mass Properties.

• We need specific short- and long-term goals laid out to convince a college professor to spend a little more of the precious free time at hand in assisting SAWE. WE need to convince a candidate the endeavor is worth the effort.

Therefore, as approved by the Board of Directors, SAWE will focus this year and beyond on developing and sustaining our relationships with Academia. In order to do so, we need the active participation from you, our local SAWE chapters.

SAWE requests:

 Each Chapter provide a name and corresponding email address of a chapter member that would act as a representative of the SAWE to the University Academic Liaison in order to support the interface between Industry and Academia.

Dr. Gerren and SAWE Academic Committee is in the process of contacting and soliciting focal points within Universities to secure Faculty Liaisons. Once these liaisons are established, nearby SAWE chapters will communicate through their respective Faculty Liaison with e-mail announcements, flyers, or any other form of communication events happening within their nearby local SAWE Chapter. The SAWE Academic Committee will be responsible for informing Faculty Liaisons of SAWE activities including SAWE regional and international events, including training opportunities and eventually Mass Properties Certification opportunities.

Please consider becoming a chapter representative of the SAWE with the University Academic Liaison.  If interested, please coordinate position availability with your chapter leadership and provide your contact information to Dr. Gerren at Donna.Gerren@colorado.edu.

As Dr. Gerren stated to the Board of Directors, “We must get universities involved”.

Sincerely,

Clint Stephenson

Standards Public Review

RP A-7, Management and Control for Military Aircraft, is in the public draft review stage and is posted in the Standards Public Review page. This document provides the means for establishing a system of mass properties management and control during the development, follow-on development, and throughout the life cycle of military aircraft programs. The Review period for RP A-7 ends November 7, 2019.

RP M-4, Supplier Weight Control for the Marine Industry, is also in the public draft review stage and is posted to the Standards Public Review page. This Recommended Practice (RP) is intended for use by vessel Designers/Builders and the marine supplier community. For the Designer/Builder, it outlines an effective methodology for involving marine industry suppliers in the shipyard’s comprehensive weight control plan. For the supplier of shipboard equipment, it provides a framework of what the shipyard needs in terms of mass properties input to effectively manage the overall mass properties of the vessel. It is hoped that this RP will help establish the foundation for a productive vessel Designer/Builder – marine supplier working relationship. The review period for RP M-4 ends October 26, 2019.

Impromptu Conference Finance and Training Meeting

Fred Brown, Conference Budget Coordinator; Errol Oguzhan, Senior VP; Bill Boze, Executive Director

While Errol was in town for other work, an impromptu meeting at O’Conner Brewing in Norfolk, VA was held to discuss Conference Finance and Training. Executive Director, Senior VP and Conference Budget Coordinator attending.

Don’t hesitate to reach out to local chapters while you are in town on work! Whether you meet up with one person or just happen to be in town for a chapter event, this is a great opportunity to network! It is always great getting to be with SAWE members outside of the International Conference as well.
