Pogo in Liquid Fueled Rocket Motors The pogo phenomenon, or fuel pump inlet pressure fluctuation/ cavitation due to tuning feed line resonant frequencies was a major concern in the early space program. Pump tests showed that as inlet pressures were reduced toward cavitation, the pump started acting as an amplifier, causing large oscillations in the thrust chamber pressure. As the rocket engine thrust develops, liquid propellant is cyclically forced into the turbopump. This fluctuating fluid pressure is converted into an unintended and variable increase in engine thrust, with the net effect being longitudinal axis vibration that could result in spacecraft structural failure. -

LUNAR NETWORK TRACKING ARCHITECTURE for LUNAR FLIGHT Shane B
LUNAR NETWORK TRACKING ARCHITECTURE FOR LUNAR FLIGHT Shane B. Robinson∗ A trade study was conducted with the objective of comparing and contrasting the radiometric naviga- tion performance provided by various architectures of lunar-based navigations assets. Architectures considered consist of a compliment of two beacons located on the lunar surface, and two orbiting bea- cons that provide range and range-rate measurements to the user. Configurations of these assets include both coplanar and linked constellations of frozen elliptic orbiters and halo orbiters. Each architecture was studied during the lunar-approach, lunar-orbit, and landing phases of a South Pole lunar sortie mis- sion. Navigation filter performance was evaluated on the basis of filter convergence latency, and the steady state uncertainty in the navigation solution. The sensitivity of the filter solution to Earth-based tracking augmentation and availability of range measurements was also studied. Filter performance was examined during the build up of the lunar-based navigation system by exploring different combi- nations of orbiting and surface-based assets. 1 INTRODUCTION The objective of the work outlined in this document is to conduct a parametric trade intended to evaluate some proposed constellations of moon-orbiting navigation and communication beacons. These orbiting beacons are intended to support the lunar missions of NASA’s Constellation program. This study is sponsored by the flight performance systems integration group at JPL (FPSIG), whose work is funded by the NASA Constellation program office. The work outlined in this report will focus on investigating lunar network aided navigation performance during near lunar phases of baseline missions proposed by the Constellation program. -
NASA: Issues for Authorization, Appropriations, and Oversight in the 113Th Congress
NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Daniel Morgan Specialist in Science and Technology Policy July 11, 2013 Congressional Research Service 7-5700 www.crs.gov R43144 CRS Report for Congress Prepared for Members and Committees of Congress NASA: Issues for Authorization, Appropriations, and Oversight in the 113th Congress Summary Spaceflight fascinates and inspires many Americans, but in a time of constrained federal budgets, it must compete with a multitude of other national priorities. As the 113th Congress conducts oversight and considers authorization and appropriations legislation for the National Aeronautics and Space Administration (NASA), an overarching question is how NASA should move forward within budget constraints. The National Aeronautics and Space Administration Authorization Act of 2010 (P.L. 111-267) set a new direction for NASA’s human spaceflight programs. For access to low Earth orbit, including the International Space Station (ISS), it confirmed NASA’s plans to develop a commercial space transportation capability for both cargo and astronauts. The first commercial cargo flight for ISS resupply was conducted in May 2012. Pending the planned availability of commercial crew transportation in 2017, NASA is paying Russia to carry U.S. astronauts to and from the ISS on Soyuz spacecraft. Issues for Congress include the cost, schedule, and safety of future commercial crew services, as well as the need for alternatives if commercial providers do not succeed. For human exploration beyond Earth orbit, the 2010 NASA authorization act mandated development of the Orion Multipurpose Crew Vehicle and the Space Launch System (SLS) rocket to launch Orion into space. -
