Turbopump Design and Analysis Approach for Nuclear Thermal Rockets
Turbopump Design and Analysis Approach for Nuclear Thermal Rockets Shu-cheng S. Chen1, Joseph P. Veres2, and James E. Fittje3 1NASA Glenn Research Center, Cleveland, Ohio 44135 2Chief, Compressor Branch, NASA Glenn Research Center, Cleveland, Ohio 44135 3Analex Corporation, 1100 Apollo Drive, Brook Park, Ohio 44142 1(216) 433-3585, [email protected] Abstract. A rocket propulsion system, whether it is a chemical rocket or a nuclear thermal rocket, is fairly complex in detail but rather simple in principle. Among all the interacting parts, three components stand out: they are pumps and turbines (turbopumps), and the thrust chamber. To obtain an understanding of the overall rocket propulsion system characteristics, one starts from analyzing the interactions among these three components. It is therefore of utmost importance to be able to satisfactorily characterize the turbopump, level by level, at all phases of a vehicle design cycle. Here at NASA Glenn Research Center, as the starting phase of a rocket engine design, specifically a Nuclear Thermal Rocket Engine design, we adopted the approach of using a high level system cycle analysis code (NESS) to obtain an initial analysis of the operational characteristics of a turbopump required in the propulsion system. A set of turbopump design codes (PumpDes and TurbDes) were then executed to obtain sizing and performance characteristics of the turbopump that were consistent with the mission requirements. A set of turbopump analyses codes (PUMPA and TURBA) were applied to obtain the full performance map for each of the turbopump components; a two dimensional layout of the turbopump based on these mean line analyses was also generated. -

Jp, Manager, Research & Engineering Development, Aero Engine, Space & Defense Business Area OGUCHI Hideo : Manager, Space Development Department, Aero Engine, Space & Defense Business Area NIIYAMA Kazuki : Ph. D., Manager, Space Development Department, Aero Engine, Space & Defense Business Area SHIMIYA Noriyuki : Space Development Department, Aero Engine, Space & Defense Business Area LE-9 is a new cryogenic booster engine with high performance, high reliability, and low cost, which is designed for H3 Rocket. It will be the first booster engine in the world with an expander bleed cycle. In the designing process, the performance requirements of the turbopump and other components can be concurrently evaluated by the mathematical model of the total engine system including evaluation with the simulated performance characteristic model of turbopump. This paper reports the design requirements of the LE-9 turbopump and their latest development status. Liquid oxygen 1. Introduction turbopump Liquid hydrogen The H3 rocket, intended to reduce cost and improve turbopump reliability with respect to the H-II A/B rockets currently in operation, is under development toward the launch of the first H3 test rocket in FY 2020. In rocket development, engine is an important factor determining reliability, cost, and performance, and as a new engine for the H3 rocket first stage, an LE-9 engine(1) is under development. A rocket engine uses a turbopump to raise the pressure of low-pressure propellant supplied from a tank, injects the pressurized propellant through an injector into a combustion chamber to combust it under high-temperature and high- pressure conditions. -

SSC17-X-02 Breaking (Space) Barriers for 50 Years: The Past, Present, and Future of the DoD Space Test Program Barbara Manganis Braun, Sam Myers Sims, James McLeroy The Aerospace Corporation 2155 Louisiana Blvd NE, Suite 5000, Albuquerque, NM 87110-5425; 505-846-8413 [email protected] Colonel Ben Brining USAF SMC/ADS 3548 Aberdeen Ave SE, Kirtland AFB NM 87117-5776; 505-846-8812 [email protected] ABSTRACT 2017 marks the 50th anniversary of the Department of Defense Space Test Program’s (STP) first launch. STP’s predecessor, the Space Experiments Support Program (SESP), launched its first mission in June of 1967; it used a Thor Burner II to launch an Army and a Navy satellite carrying geodesy and aurora experiments. The SESP was renamed to the Space Test Program in July 1971, and has flown over 568 experiments on over 251 missions to date. Today the STP is managed under the Air Force’s Space and Missile Systems Center (SMC) Advanced Systems and Development Directorate (SMC/AD), and continues to provide access to space for DoD-sponsored research and development missions. It relies heavily on small satellites, small launch vehicles, and innovative approaches to space access to perform its mission. INTRODUCTION Today STP continues to provide access to space for DoD-sponsored research and development missions, Since space first became a viable theater of operations relying heavily on small satellites, small launch for the Department of Defense (DoD), space technologies have developed at a rapid rate. Yet while vehicles, and innovative approaches to space access. -

Cannon NASA Marshall Space Flight Center, Huntsville, Alabama Corey Brown Aerojet-Rocketdyne, West Palm Beach, Florida 12.1 Introduction Earth to orbit launch vehicles are propelled by rocket engines and motors, both liquid and solid. This chapter will discuss liquid engines. The heart of a launch vehicle is its engine. The remainder of the vehicle (with the notable exceptions of the payload and guidance system) is an aero structure to support the propellant tanks which provide the fuel and oxidizer to feed the engine or engines. The basic principle behind a rocket engine is straightforward. The engine is a means to convert potential thermochemical energy of one or more propellants into exhaust jet kinetic energy. Fuel and oxidizer are burned in a combustion chamber where they create hot gases under high pressure. These hot gases are allowed to expand through a nozzle. The molecules of hot gas are first constricted by the throat of the nozzle (de-Laval nozzle) which forces them to accelerate; then as the nozzle flares outwards, they expand and further accelerate. It is the mass of the combustion gases times their velocity, reacting against the walls of the combustion chamber and nozzle, which produce thrust according to Newton’s third law: for every action there is an equal and opposite reaction. [1] Solid rocket motors are cheaper to manufacture and offer good values for their cost. -

Box 808, Moorpark, CA 93020-0808, USA Abstract Those who fear development of nuclear propulsion for space travel forget that considerable work on it has already been done, starting in the 1950s, and that the concept of a nuclear rocket was safely and successfully tested in the 1960s.

Strickland,2 Kenneth D. Philippart,3 and Thomas V. Giel Jr.4 Jacobs Space Exploration Group/ESSCA/NASA Marshall Space Flight Center, Huntsville, AL, 35812 USA This paper discusses the engine system design, hot-fire test history and analyses for the RS-25 Adaptation Engine test series, a major hot-fire test series supporting the Space Launch System (SLS) program. The RS-25 is an evolution of the Space Shuttle Main Engine (SSME). Since the SLS mission profile and engine operating conditions differ from that experienced by the SSME, a test program was needed to verify that SLS-unique requirements could be met by the adapted legacy engines. A series of 18 tests, including one engine acceptance test, was conducted from January 2015 to October 2017, to directly support Exploration Mission-1 (EM-1), the first flight of SLS. These tests were the first hot-firings of legacy SSME hardware since 2009. Major findings are described along with top level overview of the engine system. I.
