EDWARDS AFB, Calif. Testing is underway of critical components for integration into the world's first full flow cycle hydrogen/oxygen boost engine. Recent tests of the Integrated Powerhead Demonstration project here established a technical first for the United States and mark the first advancements in boost engine technology since the space shuttle main engine was initially developed in the 1970's. The Department of Defense's Integrated Powerhead Demonstration project developed by the Air Force Research Laboratory Propulsion Directorate is ongoing at the Aerojet-Complex test facilities in Sacramento.

On June 15, 2011, the Air Force Space Command established a new vision, mission, and set of goals to ensure continued U.S. dominance in space and cyberspace mission areas. Subsequently, and in coordination with the Air Force Research Laboratory, the Space and Missile Systems Center, and the 14th and 24th Air Forces, the Air Force Space Command identified four long-term science and technology (S&T) challenges critical to meeting these goals. One of these challenges is to provide full-spectrum launch capability at dramatically lower cost, and a reusable booster system (RBS) has been proposed as an approach to meet this challenge. The Air Force Space Command asked the Aeronautics and Space Engineering Board of the National Research Council to conduct an independent review and assessment of the RBS concept prior to considering a continuation of RBS-related activities within the Air Force Research Laboratory portfolio and before initiating a more extensive RBS development program. The committee for the Reusable Booster System: Review and Assessment was formed in response to that request and charged with reviewing and assessing the criteria and assumptions used in the current RBS plans, the cost model methodologies used to fame [frame?] the RBS business case, and the technical maturity and development plans of key elements critical to RBS implementation. The committee consisted of experts not connected with current RBS activities who have significant expertise in launch vehicle design and operation, research and technology development and implementation, space system operations, and cost analysis. The committee solicited and received input on the Air Force launch requirements, the baseline RBS concept, cost models and assessment, and technology readiness. The committee also received input from industry associated with RBS concept, industry independent of the RBS concept, and propulsion system providers which is summarized in Reusable Booster System: Review and Assessment.

Since initial use in 1958 for the X-15 rocket-powered research airplane, the Rocket Engine Test Facility has proven essential for testing and servicing rocket-powered vehicles at Edwards Air Force Base. For almost two decades, several successful flight-test programs utilized the capability of this facility. The Department of Defense has recently demonstrated a renewed interest in propulsion technology development with the establishment of the National Aerospace Initiative. More recently, the National Aeronautics and Space Administration is undergoing a transformation to realign the organization, focusing on the Vision for Space Exploration. These initiatives provide a clear indication that a very capable ground-test stand at Edwards Air Force Base will be beneficial to support the testing of future access-to-space vehicles. To meet the demand of full integration testing of rocket-powered vehicles, the NASA Dryden Flight Research Center, the Air Force Flight Test Center, and the Air Force Research Laboratory have combined their resources in an effort to restore and upgrade the original X-15 Rocket Engine Test Facility to become the new Rocket Vehicle Integration Test Stand. This report describes the history of the X-15 Rocket Engine Test Facility, discusses the current status of the facility, and summarizes recent efforts to rehabilitate the facility to support potential access-to-space flight-test programs. A summary of the capabilities of the facility is presented and other important issues are discussed.

The Air Force Research Laboratory (AFRL), in order to support the Evolved Expendable Launch Vehicle (EELV) Program, recently activated a large liquid rocket engine test stand after a 25 years dormancy. Test Stand 1A, located at Edwards AFB CA, was left in a semi-abandoned condition since the early 1970's. With no definitive plans for re-activation, the facility was left to weather in the dry desert air. The objective was to provide the Air Force with the capability to test large liquid rocket engines up to 1.6 million pounds of thrust which utilize liquid oxygen for the oxidizer and either liquid hydrogen or kerosene for fuel. A high pressure hydrogen turbopump spin capability was also added to enable turbopump component development testing. This paper will review the lessons learned and observations from designing, modifying, and activating the test stand and performing the initial development activity on the new RS-68 rocket engine being developed for the Boeing Delta IV launch vehicle.

On November 16th, 2000 the culminination of an aggressive 23 month, jointly funded Integrated High-Payoff Rocket Propulsion Technology (IHPRPT) Phase I Missile Propulsion program by the Air Force Research Laboratory Propulsion Directorate and Alliant Techsystems resulted in a highly successful full-scale rocket motor demonstration. This motor contained the most new technology on any one demonstration since the Trident I (C4) 25 years ago. The full-scale test incorporated new case, propellant, nozzle, and control technologies in a 92 inch diameter, 120,000 pound class motor, and verified achievement of the Phase I program specific impulse, mass fraction, and cost goals. The technologies that were demonstrated have the potential to yield a 23% increase in payload capability at a 32 % lower cost for solid booster space lift applications are ready for transition into strategic missiles, small and large launch vehicles as stages or strap-on boosters. The IHPRPT Phase I Missile Propulsion demonstration is the first in a series of tests that are part of a three phased, government and industry coordinated effort that began in 1996 with the vision to double the propulsion capability by 2010. The Phase II programs, awarded during the past year, are part of the government/industry Technology for the Sustainment of Strategic Systems (TSSS) effort to maintain critical technology capability.

This study was undertaken in response to a request by the U.S. Air Force that the National Research Council (NRC) examine whether the technologies that underlie the concept of a hypersonic, air-launched, air-breathing, hydrocarbon-fueled missile with speeds up to Mach 81 can be demonstrated in time to be initially operational by 2015. To conduct the study, the NRC appointed the Committee on Review and Evaluation of the Air Force Hypersonic Technology Program, under the auspices of the Air Force Science and Technology Board.

The Boeing Company last week tested a state-of-the-art liquid oxygen turbopump, marking a significant step forward in the development of next-generation rocket engine technology. A team of Boeing's Rocketdyne Propulsion & Power unit, Air Force, and NASA personnel conducted the hot-fire testing at NASA's John C. Stennis Space Center (SSC) in Mississippi. This test, one of nine that have been planned, follows a related series of hot-fire tests in which a Rocketdyne-built pre-burner -- which provides oxygen-rich gasses to the oxidizer turbopump turbine drive -- went 'six for six' in that series. The Rocketdyne pre-burner was subsequently attached to the new oxidizer turbopump for its testing. Both the oxidizer turbopump and the pre-burner test series are for the Air Force Research Laboratory's (AFRL) Integrated Powerhead Demonstration (IPD). Upon completion of its hot-fire test series, the oxidizer turbopump will become part of the IPD engine system and help to provide advancement of key technologies that could find application in future Air Force rocket applications or NASA's Next Generation Launch Technology program.
