ASNE is the leading professional engineering society for engineers, scientists and allied professionals who conceive, design, develop, test, construct, outfit, operate and maintain complex naval and maritime ships, submarines and aircraft and their associated systems and subsystems.  ASNE also serves the educators who train the professionals, researchers who develop related technology, and students who are preparing for the profession.  Society activities provide support for the U.S. Navy; U.S. Coast Guard; U.S. Marine Corps; U.S. Merchant Marine and U.S. Army.

ASNE is the seventh oldest technical society in the United States.  It was founded in 1888 by a group of naval engineering pioneers, most of them officers of the U.S. Navy's Engineering Corps, who sought a unified approach to their profession in order to make the most of new advances in technology. The purposes of ASNE are:           

  • to advance the knowledge and practice of naval engineering in public and private applications and operations,
  • to enhance the professionalism and well-being of members, and
  • to promote naval engineering as a career field.

For 125 years, the Society’s objectives have been strengthened and preserved to meet the changing needs of a time-honored profession. Today ASNE conducts a variety of technical meetings and symposia, publishes the highly regarded Naval Engineers Journal and a number of other technical proceedings and publications, and fosters professional development and technical information exchange through technical committees, local section activities and cooperative efforts with government organizations and other professional societies.

The Society's annual meeting, ASNE Day, is typically held in February of each year in the Washington, DC, area. The meeting features major addresses by high level industry and government leaders and panel discussions by leading members of the profession.  It also includes presentation and discussion of technical papers on a variety of timely naval engineering topics, presentation of the Society's prestigious annual awards and a large exposition with government and industry exhibits covering the full spectrum of naval engineering technology. ASNE Day is highlighted by the Society’s annual Honors Gala, attended by hundreds of executives and senior managers from both government and industry.

Our website is designed to not only serve our members, but also to support scholars, students and others interested in the varied field of naval engineering.  We welcome your suggestions on ways we can improve your experience.

Breaking down the question: 

  1. What do you know that "pushes" objects? By "push" we mean change the direction, speed, and acceleration of something else.
  2. How would you move something that weighs 8 pounds (like a gallon of milk)? How about something that weighs 100 pounds (like a lawnmower)? What is the same? What is different?
  3. What does an engine do? How do you know?

Research time! There are no bad guesses, just questions to research. Take 1 minute to write down a hypothesis about how ships move in the water. Then, answer these three questions:

4.  What topics would you research to prove or disprove your hypothesis?

This video is six minutes long, and has a lot of information. You may need to watch it 2-3 times, and you definitely should take notes. It introduces many of the words that engineers use when they are designing ships to float. We put some guiding questions below the video.

Guiding Questions

What type of energy is converted into mechanical energy?

What does the slider-crank mechanism do?

"IC engine" is short for "internal combustion engine." Where does the combustion occur?

What fuel is used in the uncontrolled spontaneous combustion?

What pushes the piston downward?

What creates the engine's exhaust?

Final task. Sketch a diesel engine and connect it to a propeller.

This video uses a mechanics perspective to show different components of the diesel engine. You are probably familiar with gasoline-powered cars. This video shows how diesel engines (used in automobiles and ships) are slightly different.


Guiding Questions

How does a gasoline engine ignite the air-fuel mixture? How does the ignition occur in diesel engines?

Which engine depends on compressing fuel to create a spontaneously combustion?

What does the throttle valve do in a gasoline engine?

How do you increase the power generated by a diesel engine?

Use this animation to answer the application questions below.

Application Questions

What does the red arrow represent?

What pushes the piston down?

What energy starts the diesel piston?

What converts the mechanical energy of the piston into the mechanical energy of the drive shaft?

Use the FLEET game and the bobsledding video below to answer the application questions below.


Application Questions

Complete the Speed Test in FLEET. What part of your Speed Test is like the beginning of the bobsled run?

How does gravity affect the bobsled? How does gravity affect your ship in FLEET?

What could you do in FLEET to simulate how the bobsled moves when everyone is in the bobsled?
