PARIS - “Military is where the commercial business was 10 years ago,” says GE Aviation president and GEvice chairman David Joyce. With commercial now set after a decade of renewal (the CF6 replaced by the GEnx, GE90 by GE9X, CFM56 by Leap, CF34 by Passport, and the emergence of the Catalyst turboprop engine), hundreds of engineers and research and development resources are being tasked with creating future generations of military powerplants. Now that the commercial side has proved that new materials such as ceramic matrix composites and technologies such as additive manufacturing are viable, affordable and producible, the military has the confidence to lead the march into new territory.
Technologies developed for commercial engines have enabled new military capabilities; in turn, military research and development will enable even newer commercial engines decades into the future. It's a virtuous cycle, Joyce explains.
GE is on a roll: it has won the U.S. Army's ITEP competition to replace all T700 engines in Black Hawk and Apache helicopters with the ultra-fuel-efficient single-shaft ITEP next-gen helicopter engine, and it won contracts worth a billion dollars to develop its AETD three-stream adaptable fighter engine as far as demonstrating it on the ground in an F-35. Flight tests could follow, as could eventual reengining of the F-35 fleet. But in any case, GE will be ready with an engine for sixth-generation fighters.
In addition, the ubiquitous F404/F414 is being upgraded and continues to win new competitions, including the USAF's new Boeing-Saab T-X trainer and several foreign future fighter programs; the T408 turboshaft powers the new Sikorsky CH-53K King Stallion; and a team is working full time on competing to reengine the B-52 bomber. Business is growing “at really good rates” on both manned and unmanned “black” programs, says Joyce, and hybrid electric is being studied for future applications including UAVs, he adds.
He believes GE already has the enabling technologies for the next decade, “but industrializing them is a different thing.” The company has already invested “billions of dollars” in developing a manufacturing and supply chain of materials and technologies for its commercial engines, and this will continue,
“Additive manufacturing may be the most disruptive technology that I've seen in the industry in a long time,” says Joyce, “as it opens up a space for designers and for manufacturing that is on a different dimensional plane. It takes a long time to learn how to design with additive. It takes even longer to learn how to manufacture with additive at speed and high rate from a quality standpoint of view.
“We are jumping in with both feet because the results on the back end when you get it right are extraordinary,” he adds.
“It's going to pay off a whole load more in the next 20 years. This is going to be the best [real return on investment] that we've ever done.”

In response to a request from the Environmental Protection Department of Lithuania's Ministry of the Environment, EMSA is providing the country with Remotely Piloted Aircraft System (RPAS) services to assist in monitoring ship emissions, protect the marine environment and improve maritime safety. The services which began on 23 March will run for three months and will see EMSA RPAS being used to calculate the sulphur content of the fuel being used by the passing ships. Sensors on board the RPAS will measure the emissions from the exhaust plumes of vessels travelling in the main shipping lanes and when at anchorage around the Lithuanian port of Klaipeda. The sulphur content of marine fuel in this Sulphur Emission Control Area (SECA) should be no greater than 0.1%. While great interest has been shown in the emissions monitoring capability of EMSA's RPAS service, the Environmental Protection Department will also be working in collaboration with other Lithuanian authorities - including the Navy, MRCC and fisheries control services – to conduct other types of maritime surveillance missions. The aircraft being used for this service is the Schiebel CAMCOPTER® S100 and it is under contract to EMSA via a consortium led by Nordic Unmanned AS. The model is a vertical take-off and landing drone and is fitted with gas sensors and cameras covering optical and infrared spectral ranges to better detect vessel plumes and conduct maritime surveillance as required. All the information is transmitted in real-time to trained users through EMSA's RPAS Data Centre. Records of the emission measurements are encoded automatically into the THETIS-EU information sharing system. This system is operated by EMSA to assist in the enforcement of the EU sulphur directive as well as to support port inspectors when targeting vessels to be inspected. ABOUT RPAS RPAS services, offered free to all EU Member States by EMSA, have been developed to assist in ship emission monitoring and maritime surveillance operations and can operate in all seas surrounding the European Union. RPAS services can provide support to traditional coast guard functions, including search and rescue and pollution prevention and response. The services are offered to Member States individually and as part of EMSA's regional RPAS strategy, which allows multiple coast guard functions in several EU Member States to be supported by one or more RPAS services. Further expansion of RPAS regionally is planned in 2021 and 2022. ABOUT EMSA The European Maritime Safety Agency (EMSA) is a decentralised agency of the EU, based in Lisbon, Portugal. EMSA serves the EU's maritime interests for a safe, secure, green and competitive maritime sector through support for pollution prevention and response, maritime surveillance, safety and security, digitalisation and the provision of integrated maritime services, and technical assistance.
