• A technology

• A technology research park that requires unusually precise voltage and amperage control for use in sensitive research systems; and • A large-scale computer server farm in need of energy security and resilience while able to harness significant amounts of the heat created during the power generation process to drive always-on steam-powered air conditioning units, thereby significantly increasing overall efficiency of the microgrid system. At Fort Carson, Colo., the Army partnered with a local energy provider to build a photovoltaic solar array on top of a closed landfill. The White Sands Missile Range project in New Mexico, awarded last December, will provide the Army with 4.44-megawatts of installed photovoltaic capacity saving 10 million kilowatt hours of electricity and $930,000 annually. When finished, the White Sands project will be the largest renewable energy projectin the Army, more than double the size of this two-megawatt array at Fort Carson (Photo: U.S. Army) 16 By sharing resources and harnessing shared assets as well as the shared need for efficient, stable and reliable energy in that specific location, a microgrid developed as a public-private partnership might yield great advantages at reasonable cost, while also helping to get the market past the ‘tipping point’ beyond which the microgrid market can finally emerge and service the growing need for electrical power that is more specifically tailored to the needs and desires of various end-users. As with any complex undertaking there will be many parties ultimately required to achieve successful outcomes. For example, the Department of Energy will need to continue to support research projects and advanced design studies on microgrids around the country, including through its Grid Modernization Initiative. And the private sector as well as an engaged citizenry are obvious and essential elements of any effective public-private partnership effort. But what is most essential at this stage seems to be an entity with the motivation to make the market potential into reality. Given its relative size as a potential market driver this important role could and should be played by the US military. Indeed, the DoD uniquely fits the bill, for it is both a major consumer of energy and has many specific installations and functions with a compelling operational need to ensure resilient access to electrical power. Microgrids will play an important role in the future of U.S. and global electrical power systems. And, as it turns out, the DoD is already the de facto market leader. As recently observed by industry insider John Carroll, “The military is the technology leader. Every utility is looking at the Department of Defense for how they are deploying microgrids.” The next practical step is for the military to shift from ‘market leader’ More on page 41

Aerojet Rocketdyne supports ULA launch of Wideband Global SATCOM spacecraft for the U.S. Military SACRAMENTO, CA, March 18, 2017 (GLOBE NEWSWIRE) – Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), played a major role in successfully launching and placing the ninth Wideband Global SATCOM (WGS-9) spacecraft into orbit for the U.S. military. The mission was launched from Cape Canaveral Air Force Station in Florida aboard a United Launch Alliance (ULA) Delta IV rocket. Aerojet Rocketdyne propulsion systems included the RS-68A booster engine, the RL10B-2 upper-stage engine, 14 helium pressurization tanks, and a 100 lbf bipropellant apogeeraising engine aboard the WGS- 9 spacecraft. “The WGS satellites provide critical communication capabilities for our nation’s warfighters,” said Aerojet Rocketdyne CEO and President Eileen Drake. “We are honored that our propulsion systems are called upon to place these critical payloads into orbit – payloads that will help protect our nation and allied forces.” Aerojet Rocketdyne’s role in the launch began when a single RS-68A engine ignited to boost the Delta IV off the pad, providing 702,000 pounds of lift-off thrust. The RS- 68A is the world’s most powerful liquid hydrogen/liquid oxygen engine. The RS-68 family of engines has now flown 35 commercial and government missions with 100 percent mission success. 17 After the upper stage separated from the launch vehicle, a single RL10B-2 upper-stage engine ignited to place the payload into orbit. The RL10B-2 delivers 24,750 pounds of thrust to power the Delta IV upper stage, using cryogenic liquid hydrogen and liquid oxygen propellants. The RL10B-2 was developed from the RL10 family of upper-stage engines, which has accumulated one of the most impressive track records of accomplishments in the history of space propulsion. More than 475 RL10 engines have supported launches over the last 50 years, playing a vital role in placing military, government and commercial satellites into orbit, and powering scientific space probes on every interplanetary mission in our solar system. ARDÉ, a subsidiary of Aerojet Rocketdyne based in New Jersey, manufactures the pressure vessels on the first and second stages of the launch vehicle. Once separated from the launch vehicle, WGS-9 will perform multiple burns on Aerojet Rocketdyne’s High Performance Apogee Thruster (HiPAT) rocket engine to complete the orbit raising from Geosynchronous Transfer Orbit to its final geosynchronous orbital position. The HiPAT rocket engine has a 100 percent mission success track record spanning over 115 missions, including all WGS spacecraft. The Boeing-built WGS satellites provide increased military communications capabilities for U.S. and More on page 41
