A Brief History of Anti-Submarine Warfare

By Globe Composite | Aug 9, 2018 11:48:00 AM

Submarines are once again being recognized as a key factor in maintaining a powerful military. Historically it has proved impossible for a country to keep global military status, without dominance at sea. Since World War I, it has also been impossible for surface ships to hold dominance at sea, without the use of submarines. In fact, today the use of submarines is not only pivotal to naval campaigns, but with their growing cruise and ballistic missile capabilities, subs are also an important part of any major land offensive.

Even before a conflict arises, a submarine’s ability to deploy military strength to an area without being detected is strategically invaluable. Conversely then, the ability to neutralize an opponent’s underwater force must be a primary objective. As submarines become more pivotal to military success, never before has Anti-Submarine Warfare (ASW) been more important.

The Silent Service is Listening

By Globe Composite | May 15, 2018 11:46:00 AM

While the defining aspect of the Silent Service is stealth, that is only half the story. If submarines where people, they would be described as the strong silent type, great listeners and keenly aware of those around them.  

Though an anthropomorphized submarine sounds like a very “sensitive” being, they are really more like sharks, whose sensitive ability to “hear” their environment allows them to be the ultimate underwater hunters.

The “Silent Service” becomes even quieter

By Globe Composite | Mar 8, 2018 12:02:00 PM

The defining aspect of Submarines, has always been stealth. From the first human powered submersible to the latest nuclear-powered subs, the effectiveness of these underwater vehicles is based on not being detected. Once a sub is hidden beneath the waves, its next best tactic is to remain quiet. If a submarine cannot be seen or heard, then it can’t be found, attacked and destroyed.

Is China taking the lead in submarine propulsion?

By Globe Composite | Feb 6, 2018 12:02:00 PM

A new type of technology might currently be in development by China, that could lower the acoustic signature of submarines. In a traditional submarine, a propeller is attached to a driveshaft which is turned by a large engine or hydraulic system. These types of systems rely on a great deal of machinery and moving parts, both create lots of noise in an environment where stealth rules supreme. 

In the "Silent Service", making as little noise as possible to evade detection is always the goal. To that end, a new concept in propulsion called a “Rim-Driven Propeller” or RDP (also known as a Rim-Driven Thruster or Rim-Driven Pumpjet) is being considered. An RDP removes the hub, driveshaft and gearbox from a submarine’s typical propulsion system, thereby giving the sub even greater stealth.

Using the Best Gasket Material for the U.S. Navy

By Globe Composite | Nov 15, 2017 11:42:33 AM

Finding the right gasket material for sealing critical applications can be a challenge. Before engineers can even begin to think about installing and testing a new gasket, they face the critical responsibility of selecting a material that can withstand a range of operating temperatures and pressures, harsh environmental conditions, and yet is flexible enough to achieve a proper seal without failure. It is not an easy task.

As mechanical engineers push the limits of what systems can achieve, the demands put on all component parts also increases. Traditional parts made of metal, plastic, or rubber simply cannot keep pace with the demands of modern defense or industrial applications. Even in existing applications, parts are expected to last longer and reduce replacement costs. Few other gasket applications are as critical as having fail-safe gaskets on an underwater vehicle.

Intelligent Marine Robots are Here

By Globe Composite | Nov 1, 2017 3:36:12 PM

What's cooler than robots? Intelligent underwater robots!

While high-flying drone vehicles have been in the news quite a lot this year, a new generation of stealthy underwater drones have gone through an amazing evolution. Underwater robots, also known as Unmanned Underwater Vehicles or UUVs, have been around for a while. UUVs are basically any vehicle that's able to operate underwater without a human on board. Some UUVs need a human to directly control them, and are aptly named Remotely Operated underwater Vehicles or ROVs. However, a new generation of intelligent unmanned underwater vehicles are now available. Known as Autonomous Underwater Vehicles or AUVs, and they have opened the mysteries under the sea, as no other underwater technology to date.

Meeting Performance Challenges with Composite Materials

By Globe Composite | Oct 10, 2017 5:12:54 PM

Great strides are being made introducing various composite materials for Industrial and Marine applications.  Composites are radically changing the cost/performance curve in the development of new products.

The Design Challenge

Globe Composite Solutions was recently contacted by an international company that was developing a new generation of outboard marine engines to fulfill the emerging global demand for energy-efficient engines. Their new engine required greater cooling capacity than typical outboard engines. In addition, the manufacturer was under a tight timeline to come up with a cost-effective solution. Globe Composite is well known for designing and manufacturing composite components that can withstand adverse operating conditions. Globe’s 30+ years of experience in providing components for pump applications was particularly relevant to address this challenge.

Product Showcase: Globe Impellers & Self-Lubricating Materials

By Globe Composite | Jun 4, 2015 3:00:00 PM

 

What Does Self-Lubricating Mean?

Self-lubrication by definition means that the lubricating agent must be an integral element of the original material.  The lubricating agent can't be a material added on or attached to the original material.  It can't break down and must be a part of the original material for the part's life's expectancy. One of our most popular self-lubricating products is the our Globe impeller, or the Run-Dry® Impeller
