This book was released on 2015 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The testing of solid and liquid rocket propulsion systems in a confined test facility often produces explosive or flammable gases which must be safely handled. Often inert gases such as nitrogen are used to lower the molar fraction of oxygen to low enough levels to minimize the probability of an explosion or deflagration. For this thesis, the chemical composition of these rocket exhaust gases mixed with air were used to determine the flammability limits of the gas mixture. Using the ideal gas law and the conservation of mass, the exhaust gas composition and gas properties such as pressure, temperature, volume and mole fractions inside the test facility were calculated. This exhaust gas composition along with La Chatelier's law was applied to an air-free basis for calculating the flammability limits of the rocket exhaust gas in air. Using Test Driven Development and Object Oriented Programming, a computer program using the Python programming language was created with a Graphical User Interface (GUI) to automate these calculations. This program was validated using existing analytical techniques developed at the Arnold Engineering Development Complex (AEDC). The results from the Python program agree well, a maximum of 1.4% difference, with the validated AEDC techniques.

This book was released on 2018-10-26 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Solid Rocket Motor Witness Test was undertaken to examine the potential for using thermal infrared imagery as a tool for monitoring static tests of solid rocket motors. The project consisted of several parts: data acquisition, data analysis, and interpretation. For data acquisition, thermal infrared data were obtained of the DM-9 test of the Space Shuttle Solid Rocket Motor on December 23, 1987, at Thiokol, Inc. test facility near Brigham City, Utah. The data analysis portion consisted of processing the video tapes of the test to produce values of temperature at representative test points on the rocket motor surface as the motor cooled down following the test. Interpretation included formulation of a numerical model and evaluation of some of the conditions of the motor which could be extracted from the data. These parameters included estimates of the insulation remaining following the tests and the thickness of the charred layer of insulation at the end of the test. Also visible was a temperature signature of the star grain pattern in the forward motor segment. Welch, Christopher S. Unspecified Center NAS1-18347; RTOP 505-63-01-17

Download or read book Some Experimental Tests to Change the Total Volume And or Molecular Weight of Rocket Engine Exhaust Gas in an Altitude Test Facility written by A. J. Zazzi and published by . This book was released on 1971 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation was conducted mainly to determine the possibility of burning fuel-rich combustible exhaust gas mixtures by the injection of either gaseous oxygen or gaseous carbon dioxide into the exhaust stream. The burning of the combustibles, especially hydrogen, results in a large volume decrease when the hot gas in cooled. The reaction of the oxygen or carbon dioxide with combustible products (hydrogen rich in this test) was possible, as evidenced by the results of the chemical analysis of the exhaust products. The possibility of generating an electrostatic field along the viscous mixing boundary between two gases was studied using argon, helium, and stream jets at different energy levels. An electrostatic field along the viscous mixing boundary between two gases (one being steam) was produced in an ungrounded installation; even with only a steam jet in an ungrounded installation, an electrostatic field was generated.

Available in PDF, EPUB and Kindle. Book excerpt: The necessity for experimental verification of rocket-engine performance at altitude or near-space conditions has long been recognized in the aerospace industry. Recent spacecraft rocket-engine research and development trends toward higher area ratios, advanced nozzle concepts, and nonequilibrium flow conside ations have made altitude simulation a requirement of development pro- grams. Recause the need for information regarding the capabilities and char- acteristics of altitude test facilities that are suitable for l%id-rocket%- engine operation was recognized, this survey was compiled with the help of representatives of industry and government agencies;% % INTROPUCTION The advent of upper-stage and spacecraft engine-vehicle development pro- grams along with the need for more rigorous performance and reliability data justified the construction of a number of altitude test facilities. The test capabilities of these facilities range from small attitude-control engines to large upper-stage engines. The altitude-simulating systems include simple diffusers coupled to the engine nozzle exit (fig. 1), steam ejector coupled to the engine-driven diffuser (fig. 2), and pumped environmental chambers coupled to a diffuser or ejector system for use during engine firing (fig. 3). Several techniques for vacuum generation exist. In addition to the conventional sys- tems of mechanical pumps and steam boilers for stem% ejectors, there are semi- portable liquid-propellant-driven steam generators.

Available in PDF, EPUB and Kindle. Book excerpt: The J-5 test cell at Arnold Engineering Development Center (AEDC) is the only national facility for testing large solid-propellant rocket motors at simulated flight-altitude conditions. However, the cell was not sited to meet the quantity-distance criteria required for testing motors containing propellant equivalent to 20,000 lb of TNT. This motor and other motors containing similar propellant amounts were being tested in J-5 using explosives safety waivers since no other facility is available in which to test them. Safety personnel concerned with the serious potential hazards for other unique test capabilities at AEDC funded a study to examine the distribution of debris and define the hazard at the J-5 test cell resulting from accidental detonation of rocket motors containing propellant equivalent to 20,000 and 30,000 lb of TNT. While the study was in progress, an actual mishap occurred during a test of one of the motors being examined in the study. The estimated sequence of events during the mishap and the distribution of motor, test cell, and building debris after the accident as compared with predicted debris arcs are presented in this paper.
