The Society of Allied Weight Engineers (SAWE) goals are to promote mass properties engineering as a specialized discipline and to provide a means for those interested in mass properties engineering to work together to further their professional goals. Since its inception in 1939, the SAWE has grown to include 22 chapters located in the United States, Brazil, Canada, Central Europe, India, and the United Kingdom and has members from over 22 countries. The Society promotes technical interchange between its members through international and regional conferences, the Weight Engineering Journal, specialized training, technical papers and a growing number of professional publications.

Scholarship Application Deadline extended to April 30, 2017.

Each year the Society of Allied Weight Engineers, Inc. sponsors the SAWE Scholarship Program.

Applicants must be children* or grandchildren (age 25 and under) of members of the SAWE worldwide who have a minimum of one year of membership as of the application deadline date. Children of deceased members are also eligible.

*For purposes of this program, children are defined as natural and legally adopted children or stepchildren of members.

Applicants must be high school seniors or graduates who plan to enroll or students who are already enrolled in a full-time undergraduate course of study at an accredited four- year college or university.

We are running very short of cover photographs for the cover of Weight Engineering, the Journal of the SAWE.

We have used aircraft photos on the last three issues and need to have some variety, i.e., ships, rockets, satellites, ground vehicles, etc.

Each photo should be accompanied by a short (one paragraph) write-up to go on the Table of Contents page. If you wish, a longer article on the subject of the photograph can be sent to be used in the Journal.

We will consider all contributions. Thanks for your help.

The Society of Allied Weight Engineers (SAWE) provides opportunities to connect with engineers and industry professionals from large and small companies from around the world. SAWE conferences and technical publications support a wide range of industries including aerospace, defense, government, marine, automotive, airline and other related industries. The SAWE is focused on:

  • Providing a means for those interested in mass properties engineering to work together to further their professional goals.
  • Promoting recognition of mass properties engineering as a specialized discipline in the entire spectrum of professional engineering.
  • Serving as a medium for the exchange of current mass properties related techniques and state of the art improvements in the profession.
  • Promoting the design and manufacture of optimum weight equipment, development of new materials, and improvements in the state of the art.
  • Encouraging members to promote continuous improvement in the interrelations between mass properties engineers for mutual benefit.
  • Publicly recognizing any person or organization that significantly enhances the professionalism of the Society or develops new technology that improves the state of the art of mass properties engineering efficiencies.
  • Promoting the inclusion of mass properties engineering in the curriculum of study in institutions of higher learning.
  • Providing training for those working in the field of Mass Properties.
