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.

  • Accord belgo-britannique pour une participation à l'Eurofighter

    Accord belgo-britannique pour une participation à l'Eurofighter

    Le groupe de défense et de sécurité britannique BAE Systems et les entreprises aéronautiques belges ont signé ce jeudi soir à Bruxelles un accord non exclusif de coopération. Il fixe les modalités de la participation de l'industrie belge au programme de l'avion de combat Eurofighter en cas de choix de cet appareil pour succéder aux F-16 vieillissants. BAE Systems et des représentants des trois associations régionales - Entreprises wallonnes de l'aéronautique (EWA), Brussels Aeronautical Group (BAG) à Bruxelles et Flemish Aerospace Group (FLAG) en Flandre se sont mis d'accord sur les modalités d'une éventuelle collaboration si le gouvernement fédéral opte pour l'Eurofighter - Typhoon, avion de chasse britannique, pour remplacer les F-16 de l'armée belge. Ce partenariat associe aussi les "clusters" qui leur sont liés, a-t-on expliqué de source industrielle en marge de la cérémonie de signature, organisée par l'ambassade du Royaume-Uni, qui promeut l'Eurofighter - Typhoon pour les Britanniques - en Belgique. Cet accord chapeaute en quelque sorte ceux déjà signés séparément par les industriels belges et les partenaires du consortium Eurofighter, rassemblant les trois principaux groupes européens du secteur - BAE Systems, Airbus Defence&Space (ASD) et Leonardo. L'accord est non-exclusif car des industriels belges ont également conclu des ententes avec le groupe américain Lockheed Martin, constructeur du chasseur furtif F-35 Lightning II, et avec le groupement français qui propose, hors d'appel d'offres, le Rafale de Dassault Aviation. Il doit servir de tremplin pour discuter de la participation de l'industrie belge à la maintenance et au soutien d'une flotte belge d'Eurofighter, au développement des capacités futures de cet appareil européen et à la définition d'une plate-forme de combat aérien future. Le gouvernement Michel souhaite acheter 34 nouveaux chasseurs, pour un montant initial de près de 3,6 milliards d'euros. https://www.lecho.be/entreprises/defense-aeronautique/accord-belgo-britannique-pour-une-participation-a-l-eurofighter/10047057.html

  • Only 20 defense firms sought $17 billion in COVID loans. Now the Trump administration is weighing a fix.

    Only 20 defense firms sought $17 billion in COVID loans. Now the Trump administration is weighing a fix.

    By: Joe Gould WASHINGTON ― Because fewer than 20 firms sought to apply for $17 billion in federal loans for Defense Department suppliers hurt by the coronavirus pandemic, the Trump administration is weighing how to broaden the eligibility requirements, a top Pentagon official said Thursday. “The challenge is that this $17 billion worth of loans comes with some fairly invasive kind of riders, and I think companies have to think very carefully about whether that makes good business sense for them,” Under Secretary of Defense for Acquisition and Sustainment Ellen Lord said at a Pentagon news conference. Treasury Secretary Steven Mnuchin, whose agency is implementing the loans, is requiring public companies seeking a share of $17 billion in coronavirus-related relief offer an equity stake to the government. “It may not be as interesting as for private companies, so that's one of the differentiators I see,” Lord said. The loans were intended for companies operating top secret facilities and with DX-rated contracts, which means the Pentagon deems them of highest national priority. “I am not sure that companies with DX-rated contracts are the ones that have the most critical needs. They have had a little less than 20 companies reach out to date,” Lord said. The Treasury Department has been in consultation with the Pentagon, and it's been open to ways the loan program could be expanded ― potentially to firms the Pentagon designates, Lord said. “So I'm hoping that early next week, between the Treasury Department and the Department of Defense, we can come back with a little bit more fidelity to the defense industrial base to better identify who might most benefit from this particular money,” Lord said. The agency had set a May 1 deadline for applications. The $17 billion tranche in the CARES Act for COVID-19 relief was widely assumed to be targeted at Boeing, which is a prime defense contractor and had indicated that it might seek assistance. However, U.S. lawmakers have said the loans are intended to span the defense supply chain, said Andrew Hunter, director of the Center for Strategic and International Studies's Defense-Industrial Initiatives Group. “I would just say the requirements under that program are pretty strict that," he said. "You have to be really in desperate need for financing and have no access to other forms of financing, you have to accept a lot of limits on how the business operates: [on] share buybacks, dividends, executive compensation. And so it's really been designed and set up as a lender of last resort to firms that really need that assistance.” https://www.defensenews.com/congress/2020/04/30/only-20-defense-firms-sought-17-billion-in-covid-loans-now-the-trump-administration-is-weighing-a-fix/
