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.

AGV Robots Disrupt the Material Handling World

By Globe Composite | Jan 11, 2018 11:43:00 AM

Automatic Guided Vehicles (AGVs) have been disrupting the Material Handling world. Now that the power of these smart mobile robots has been unleashed, each year brings new advances that are radically changing the industry. New research predicts that "Mobile robotics in material handling and logistics will become a $75bn market by 2027. It will then more than double by 2038" (Business Insider). From smart Autonomous Mobile Robots (AMRs) that move materials around a facility, to warehouse shelves that bring themselves to packers and shippers, to swarms of airport baggage AGCs (Automated Guided Carts), Material Handling is heading for more changes in 2018 than ever before.

2018 News Year's Resolution - Drive Underwater!

By Globe Composite | Dec 12, 2017 11:14:07 AM

As 2017 draws to a close, you might be wondering what amazing new technology the next year will bring. Well, there is already something fresh in 2018 for you to try: a surprising new type of underwater vehicle that will allow almost anyone to experience driving underwater in a safe and immersive environment, while still being able to feel the water and sea life around you. Imagine hopping into a car and driving under the sea among tropical fish, natural reefs, or even around a simulated Lost City of Atlantis. This newly developed car will be available in 2018 and will let people share underwater experiences together that were once only available to those with Scuba training.

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.

Airport Security Health Concerns

By Globe Composite | Oct 26, 2017 4:28:12 PM

The use of hand-held wands for individual screening, walk-through metal detectors, full-body scanners, and baggage X-ray machines, are familiar to anyone who has flown on an airplane in the past decade. Modern airports use these security devices to keep travelers safe from external threats, but how safe are the methods they use? Do modern airport security methods pose a health concern? The following is an overview of current security screening technologies, how they work, and what sort of health issues they might cause.

Quickly and Safely Clearing Conveyor Jams

By Globe Composite | Oct 18, 2017 7:45:32 AM

With packages of all sizes, shapes, and weights moving along your conveyor system daily, "log jams" are bound to occur. Often employees have to resort to "makeshift" jam break poles, or whatever is within arm's reach, to unjam conveyors. Unfortunately, when employees use these sorts of bent metal makeshift conveyor jam-up tools, safety issues or product damage can often result. Whether your company moves hundreds (or millions) of products each day, product damage or downtime due to these package jams can mean the difference between success and failure for your operation.

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.

Three Tools to Safely Clear Conveyors Jams

By Globe Composite | Aug 9, 2017 11:21:36 AM

Whether your company moves thousands or millions of packages, operational inefficiencies, product damage or downtime can mean the difference between success and failure.

Globe's engineering team noticed that distribution centers were using bent metal makeshift tools to unjam packages on conveyor systems. Sometimes the bent metal ends were welded or fastened and the sharp edges of the tool punctured the package or damaged the product. These makeshift tools aren’t easy to repair, causes product damage and are not safe for package handlers or employees.

Composite Conveyors Eliminate Metallic Interference & Increases RFID Readability

By Globe Composite | May 23, 2017 8:57:06 AM


Did you know that 72% of retailers plan to upgrade their supply chain with real-time visibility enabled by automation, sensors and analytics? And, 70% of
these retailers are planning to provide item-level RFID tracking technology. Additionally, the International Air Transport Association (IATA) shared results of a study finding that RFID can reduce the number of mishandled bags globally up to 25 percent by 2022.  

Delta Airlines, for example,  is already using RFID technology at 84 airports. 
So, what does this mean for future of material handling at parcel & distribution centers, as well as airports?
