Aerojet Rocketdyne Supports Inaugural Standard Missile-3 Block IB Guided Missile Aegis Ashore Launch

Aerojet Rocketdyne announced that its propulsion systems successfully contributed to the intercept of a virtual target during the first test of Raytheon's Standard Missile-3 (SM-3) Block IB guided missile from the Aegis Ashore weapon system. The successful test was conducted at the Pacific Missile Range Facility in Kauai, Hawaii, to demonstrate the safe launch and fly-out capability of the SM-3 Block IB guided missile. The land-based system uses the same SM-3 missile deployed on Aegis Ballistic Missile Defense cruisers and destroyers today, defending against short-to-intermediate range ballistic missile threats in the mid-course phase of flight. During the non-intercept test, Aerojet Rocketdyne's booster and dual-thrust rocket motor provided the first- and second-stage propulsion for the SM-3 Block IB guided missile, while Aerojet Rocketdyne's innovative Throttling Divert and Attitude Control System (TDACS) maneuvered the kinetic warhead to impact a virtual target. This important test provided an opportunity to gather atmospheric heating conditions in the lowest TDACS ejection scenario conducted to date.

Aerojet Rocketdyne to Provide Upper-Stage Propulsion for Revolutionary Eagles Launch System

Aerojet Rocketdyne has received a contract from Stratolaunch Systems Corporation (SSC) to provide six RL10C-1 production engines, with an option to provide an additional six RL10C-1 production engines at a later date, for the third stage of a revolutionary commercial air-launch system. The inaugural launch of Thunderbolt, the air-launch vehicle designed and developed for SSC, is scheduled for 2018. The design concept for The Eagles Launch System involves the launch of an unmanned rocket dubbed Thunderbolt, carrying a commercial or government payload from beneath the fuselage of a giant carrier aircraft. According to the concept, the carrier aircraft will be powered by six Boeing 747 class jet engines and have a wingspan greater than the length of a football field. Upon reaching a prescribed altitude, the rocket will be dropped from the aircraft, at which point two stages of solid rocket boosters will fire and propel the rocket skyward. Once the solid rocket boosters are expended, two Aerojet Rocketdyne RL10C-1 engines will ignite to ultimately place the satellite into proper orbit. The RL10C-1 is a liquid-fuel cryogenic rocket engine designed and developed from the RL10 family of upper-stage engines, which have accumulated one of the most impressive lists of accomplishments in the history of space propulsion. The RL10 has helped place numerous military, government and commercial satellites into orbit over the last five decades, and powered scientific space-probe missions to nearly every planet in its solar system. This new application for the RL10 family opens a new era within a commercial venture that will again be a platform for demonstrated reliability and mission success.

Aerojet Rocketdyne and Dynetics Announce Strategic Partnership for Advanced Aerospace Technologies and Systems

Aerojet Rocketdyne and Dynetics are announcing a strategic partnership in Huntsville, Ala., to enhance collaboration in aerospace technologies and systems. Based on marked success supporting NASA's Space Launch System (SLS) Advanced Booster Engineering Demonstration and/or Risk Reduction (ABEDRR) program, AR and Dynetics plan to expand the existing partnership to include: high-temperature, lightweight materials; next generation additive manufacturing technologies; in-space propulsion systems and high performance booster rocket engine systems. Since 2012, the Dynetics-led team has executed on NASA's SLS ABEDRR contract to reduce risks for advanced boosters that could help meet SLS' future capability needs. The team has successfully manufactured its first two full-scale, 18-foot diameter cryogenic tank barrels. The team also made recent progress in its effort to create more affordable propulsion systems. In less than four months after the contract award, the team, working closely with NASA's Marshall Space Flight Center, successfully resurrected the world's most powerful rocket engine ever flown -- the F-1 that powered the Saturn V rocket -- and test fired its 30,000 pounds-force gas generator in Huntsville, Ala. Modern instruments on the test stand measured performance properties to allow engineers a starting point for creating a new generation of affordable advanced booster propulsion systems.
