ATK propulsion, composite and spacecraft technologies supported the successful launch of a United Launch Alliance (ULA) Delta IV rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station, Florida, US.
This rocket carried a Wideband Global SATCOM satellite (WGS-6) into orbit for the US Air Force.
WGS-6 is the sixth satellite delivered by prime contractor Boeing as part of the WGS system that provides flexible, high-capacity communications for the nation's warfighters. WGS is the Department of Defence's highest capacity communications satellite providing high data rate and long-haul communications for soldiers, sailors, Marines and airmen worldwide.
"ATK is proud to leverage our engineering and manufacturing expertise to support the Delta IV launch vehicle and WGS-6 satellite," said Blake Larson, President of ATK Aerospace Group. "We are deeply committed to delivering affordable innovation that will help the war-fighters."
ATK claim that this was the fourth time the Delta IV medium-plus rocket featured four ATK 60-inch diameter Graphite Epoxy Motors (GEM-60). The 53-foot-long motors were mounted in pairs on opposing sides of the rocket, with one fixed and one vectorable nozzle per side. They burned for 90 seconds and provided more than 1.1million pounds of thrust to assist delivery of the WGS-6 satellite to its determined orbit. The composite cases, nose cones and aeroskirts for the GEM motors were fabricated at ATK's Clearfield, Utah, US facility. The solid rocket motors were produced at ATK's Magna, Utah, US facility. ATK has manufactured 58 GEM-60 boosters for the Delta IV launch vehicle since the initial flight in 2002.
For the Delta IV medium-plus launch vehicle itself, ATK supplied nine key composite structures, including:
The nozzle for Delta IV's RS-68 engine was designed and manufactured at ATK's Promontory, Utah, US facility. The Aerojet Rocketdyne-built RS-68 is the largest hydrogen-fuelled engine in the world. ATK also designed and produced the nozzle's thermal protection material, which is capable of shielding the nozzle from the extreme heat of launch when external temperatures can exceed 4,000 degrees Fahrenheit.
ATK also provided the propellant tank for the Delta IV upper stage roll control system. The tank was manufactured at ATK's Commerce, California, US facility.
Coriolis Composites has been selected by the National Institute for Aviation Research (NIAR) at Wichita State University (WSU), US, to provide a thermoplastics capable Automated Fibre Placement (AFP) system.
Boeing and Thermwood have employed additive manufacturing technology to produce a large, single-piece tool for the 777X programme. The project is demonstrating that additive manufacturing is ready to produce production quality tooling for the aerospace industry.
Innovators and industry pioneers will gather to discuss the latest applications of graphene nanotubes at the Nanoaugmented Materials Industry Summit (NAUM) 2018 in Shanghai, China, on 31 October. Visitors will also be able to see an on-site demonstration of the production of nanoaugmented products with real industrial equipment.
