This book was released on 2016 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research effort sought to examine the performance potential of a dual-expander cycle liquid oxygen-hydrogen engine with a conventional bell nozzle geometry. The analysis was performed using the NASA Numerical Propulsion System Simulation (NPSS) software to develop a full steady-state model of the engine concept. Validation for the theoretical engine model was completed using the same methodology to build a steady-state model of an RL10A-3-3A single expander cycle rocket engine with corroborating data from a similar modeling project performed at the NASA Glenn Research Center. Previous research performed at NASA and the Air Force Institute of Technology (AFIT) has identified the potential of dual-expander cycle technology to specifically improve the efficiency and capability of upper-stage liquid rocket engines. Dual-expander cycles also eliminate critical failure modes and design limitations present for single-expander cycle engines. This research seeks to identify potential LOX Expander Cycle (LEC) engine designs that exceed the performance of the current state of the art RL10B-2 engine flown on Centaur upper-stages. Results of this research found that the LEC engine concept achieved a 21.2% increase in engine thrust with a decrease in engine length and diameter of 52.0% and 15.8% respectively compared to the RL10B-2 engine. A 5.89% increase in vacuum specific impulse was also observed. The implications of these results could lead to significant launch cost savings and replacement of aging expander cycle technology in the rocket propulsion industry. In order to fully validate the results of this research, more knowledge is required regarding the heat transfer characteristics of supercritical oxygen for rocket thrust chamber cooling. Future work in this topic will focus on experimental LOX heat transfer research and model optimization to improve heat transfer estimations in the baseline model developed in this research and further explore the optimal performance potential and limitations of the LEC engine.

This book was released on 2018-06-30 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Expander Test Bed (AETB) is a key element in NASA's Space Chemical Engine Technology Program for development and demonstration of expander cycle oxygen/hydrogen engine and advanced component technologies applicable to space engines as well as launch vehicle upper stage engines. The AETB will be used to validate the high pressure expander cycle concept, study system interactions, and conduct studies of advanced mission focused components and new health monitoring techniques in an engine system environment. The split expander cycle AETB will operate at combustion chamber pressures up to 1200 psia with propellant flow rates equivalent to 20,000 lbf vacuum thrust. Mitchell, J. P.

Book excerpt: The Air Force Research Laboratory and Pratt & Whitney have teamed to demonstrate an advanced expander cycle engine. Scheduled to be the first of the Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program engine demonstrators, it is scheduled to be tested in late 2000. The expander cycle offers low cost, high thrust to weight and a highly reliable engine ideally suited for upper stages and some future military spaceplane concepts. This technology program will push the performance envelope of existing expanders to higher thrust. Throughout design and manufacture, new methods have been adopted which will increase reliability and reduce component fabrication times.
