  Honeywell and U.S. Army to demo next-generation T55 engine for Chinook helicopters

  Honeywell has entered into an agreement with the U.S. Army to demonstrate and fly its upgraded T55 engine on the heavy-lift, twin-engine Chinook helicopter. The new 6,000-horespower engine is 25% more powerful and consumes 10% less fuel than the current T55. New modifications also make the next-generation T55 easier to maintain with lower operating costs and increased readiness for the warfighter. The new T55-GA-714C engine is specifically designed for next-generation military operators, and will improve the Chinook helicopter's ability to lift troops and heavy cargo for the U.S. Army and National Guard. Because the engine is based closely on the T55 version currently in use, almost no airframe changes are required — the same intake, exhaust and engine airframe mounts are used. This provides the Army and National Guard with a major engine improvement without the need to retrain their maintenance and operational staff. The design improvement will be demonstrated as part of the Cooperation Research and Development Agreement process with the U.S. Army. The engine upgrade can be incorporated either by modifying existing engines at overhaul in the U.S. fleet or with new production engines. "Honeywell has spent years designing and developing the T55-GA-714C engine as part of our commitment to push the T55's power beyond the needs of the Chinook helicopter," said Dave Marinick, president, Engines and Power Systems, Honeywell Aerospace. "For 60 years, we've powered the world's most premier heavy-lift helicopter, and this latest improvement increases performance while saving important program dollars and maintenance hours as well as increasing mission readiness. We are proud of our legacy on the Chinook helicopter, and we are committed to continuously improve the T55 engine." The installation and demonstration of the advanced T55 engine will take place on a CH-47F Chinook at Fort Eustis in Newport News, Virginia, under the supervision of the U.S. Army Combat Capabilities Development Command Aviation & Missile Center. The demonstration will show the ease of installation and prove out the engine's new compressor design that brings additional performance and reduces fuel burn. After that, Honeywell will complete the final qualification process for the new engine design. Honeywell first delivered the T55 engine to the U.S. Army in 1961 at 2,050 shaft horsepower on the CH-47A helicopter. Since that time, the engine's power has nearly tripled to 6,000 shaft horsepower. Each performance increase on the T55 is accompanied by reduced fuel burn, increased reliability and decreased maintenance hours. The T55 engine is the world leader in powering heavy lift helicopters. Over 900 CH-47 helicopters are operated today by various militaries around the world.

  ANALYSIS | Trump's NATO comments aren't cause for panic — but they should be taken seriously, experts warn | CBC News

  There was a "keep calm and carry on" atmosphere outside the House of Commons on Monday as a political storm blew up over Donald Trump's threat to encourage Russia “to do whatever the hell they want” to NATO members he thinks aren't paying their fair share of the cost of collective defence.

  Armed with a new Arctic strategy, the Air Force seeks increased connectivity in the region

  By: Valerie Insinna WASHINGTON — With commerce, travel and international competition in the Arctic region on the rise, the Department of the Air Force will prioritize making investments that will enable greater connectivity among U.S. military assets, the Air Force's top general said July 21. “Missile warning, space capabilities, air capabilities, how you marry up fifth generation and fourth generation [fighter jets]. It's more the case as we look at the future of warfare that data will be the currency that we operate on,” said Air Force Gen. Dave Goldfein at a roll out of the department's new Arctic strategy hosted by the Atlantic Council. “It's access to data, its manipulation at the speed of relevance. ... How we build the networks that we can operate seamlessly on is where you're going to see most of our investment,” he said. In the new strategy, the U.S. Air Force and Space Force commit to enhancing its northernmost missile defense capabilities, exploring new surveillance and communications technologies and updating its dilapidated infrastructure in the region. But the strategy doesn't provide specifics on how much the service is willing to spend to make its goals a reality, and Goldfein, Air Force Secretary Barbara Barrett and Chief of Space Operations Gen. John Raymond on Tuesday didn't provide much clarity on whether the department's strategic goals will turn into actionable investments. Although the U.S. Navy has a major interest in the region's waterways, the Department of the Air Force maintains the military's largest presence in the Arctic, making up 80 percent of the Defense Department's funding efforts in the region. “We've always valued the Arctic and recognized the importance of its geostrategic location,” Barrett said. However, she added that Russia's recent build-up in region, including “a network of offensive air assets and coastal missile systems,” has led the department to be more aware of the need to recapitalize its own technology in the Arctic. Meanwhile, China — which is not technically an Arctic nation — is attempting to insert itself in the region's affairs as part of its “One Belt, One Road” initiative. That country seeks access to “rare earth minerals, hydrocarbons, and fisheries,” according to the strategy, and has pursued strategic investments that would enhance its air and sea transportation options, such as a failed plan to build an airport in Greenland. The strategy lays out several goals that could result in greater investments in areas like command, control, communications, intelligence, surveillance and reconnaissance (C3ISR), space operations and missile defense. It also states that the Air Force and Space Force will work with the other services on an Arctic communications roadmaps that explores current and emerging technologies that could expand connectivity to military forces in the region. It will also work with the joint force on developing data links and ensuring satellite coverage. For missile defense, the strategy states an interest in “continuing to work with Canada to identify materiel and non-materiel solutions to the North Warning System” and updating the missile defense surveillance system in the Northern tier. The Space Force will “develop new technologies and modernize existing assets in the Arctic necessary to ensure access to and freedom to operate in space,” the strategy states, though it does not explain what types of capabilities will be necessary. It will also develop capabilities that can better predict the weather and environmental disturbances. U.S. Air and Space Force operations in the Arctic will have to become more agile, and could involve “expanded fixed bases, unoccupied airfields, or portable radar systems.” But even though the strategy also recognizes the difficulty of moving to a more modular way of operations given the complex nature of supplying installations in remote areas that may be almost completely inaccessible during the winter months, it provides few answers on what a more disaggregated approach to Arctic operations could look like. The department needs to advocate for additional funding to modernize Air Force and Space Force installations in the region, which include major air bases in Alaska like Joint Base Elmendorf-Richardson, Thule Air Base in Greenland, and remote radar sites that make up the North Warning System, the strategy said. “To survive in the region, materials need to meet standards including: high thermal efficiency; long-term durability; tolerance to repeated freeze and thaw cycles; and resistance to permafrost degradation. Infrastructure in many austere locations, like Thule, Greenland, has deteriorated due to extreme environmental factors,” it said. https://www.defensenews.com/air/2020/07/21/armed-with-a-new-arctic-strategy-the-air-force-seeks-increased-connectivity-in-the-region/
