This book was released on 2018-06-19 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thermal vacuum facility for testing launch vehicle thermal protection systems by subjecting them to transient thermal conditions simulating re-entry aerodynamic heating is described. Re-entry heating is simulated by controlling the test specimen surface temperature and the environmental pressure in the chamber. Design requirements for simulating re-entry conditions are briefly described. A description of the thermal vacuum facility, the quartz lamp array and the control system is provided. The facility was evaluated by subjecting an 18 by 36 in. Inconel honeycomb panel to a typical re-entry pressure and surface temperature profile. For most of the test duration, the average difference between the measured and desired pressures was 1.6% of reading with a standard deviation of +/- 7.4%, while the average difference between measured and desired temperatures was 7.6% of reading with a standard deviation of +/- 6.5%. The temperature non-uniformity across the panel was 12% during the initial heating phase (t less than 500 sec.), and less than 2% during the remainder of the test.

This book was released on 1973 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a reusable space shuttle by NASA in the next decade depends in part on the design of a satisfactory thermal protection system (TPS). The booster and orbiter parts of the shuttle require TPS panels which will withstand thermoacoustic fatigue. The Langley Research Center has begun tests on early panel designs in a new acoustic fatigue facility which is capable of simulating the combined elevated temperature and acoustic environments which these panels are expected to experience. The capabilities of the facility and computer system are outlined, and problems encountered in establishing the test methods are discussed. The digital computer system which controls the acoustic and thermal test sequence and which records data from more than 20 transducers is described. Tests of a Haynes 25 TPS panel are described, and representative data from tests of the panel at 650 C are included.

This book was released on 1996-01-22 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key to opening the use of space to private enterprise and to broader public uses lies in reducing the cost of the transportation to space. More routine, affordable access to space will entail aircraft-like quick turnaround and reliable operations. Currently, the space Shuttle is the only reusable launch vehicle, and even parts of it are expendable while other parts require frequent and extensive refurbishment. NASA's highest priority new activity, the Reusable Launch Vehicle program, is directed toward developing technologies to enable a new generation of space launchers, perhaps but not necessarily with single stage to orbit capability. This book assesses whether the technology development, test and analysis programs in propulsion and materials-related technologies are properly constituted to provide the information required to support a December 1996 decision to build the X-33, a technology demonstrator vehicle; and suggest, as appropriate, necessary changes in these programs to ensure that they will support vehicle feasibility goals.

This book was released on 2018-11-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spacecraft thermal control systems are essential to provide the necessary environment for the crew and equipment to function adequately on space missions. The Ultralight Fabric Reflux Tube (UFRT) was developed by Pacific Northwest Laboratory (PNL) as a lightweight radiator concept to be used on planetary-type missions (e.g., Moon, Mars). The UFRT consists of a thin-walled tube (acting as the fluid boundary), overwrapped with a low-mass ceramic fabric (acting as the primary pressure boundary). The tubes are placed in an array in the vertical position with the evaporators at the lower end. Heat is added to the evaporators, which vaporizes the working fluid. The vapor travels to the condenser end above and cools as heat is radiated to the environment. The fluid condensed on the tube wall is then returned to the evaporator by gravity. The primary objectives for the fiscal year 1994 program included the design and fabrication of prototype UFRTs and thermal/vacuum chamber testing of these test articles. Six UFRTS, with improved titanium liners, were successfully manufactured and provided to the Johnson Space Center in July 1994. Five were tested in a thermal/vacuum chamber in September 1994. Data obtained to characterize the performance of the UFRTs under simulated lunar conditions demonstrated the design concept successfully. In addition, a trade study showed that an optimized/improved UFRT could achieve as much as a 25% mass savings in the heat rejection subsystem of future planetary-type thermal control systems.

Available in PDF, EPUB and Kindle. Book excerpt: With the advent of small satellites, including CubeSats, and their widespread use in industry and educational institutions, testing facilities are required to accommodate, in complexity, size, and cost, the miniaturisation of spacecraft. Conducting thermal-vacuum tests on Electric Propulsion Systems used in small satellites poses the limitation of needing a path for the thruster beam to safely reach its target, thus complicating the process of designing a thermal shroud that could completely enclose the thruster. This project comprised the evaluation of a TVC setup with an open thermal shroud through experimental testing and numerical analysis. Following this evaluation an improved design of a thermal shroud for testing electric thrusters was developed and validated through numerical and experimental methods. The final design produced satisfactory results, where the thermal shroud, and in turn the test satellite were able to reach desired temperatures when the satellite was dissipating low or no heat. However, as the heat dissipated from the satellite was raised the cooling performance of the thermal shroud was less effective. Nevertheless with the improved shroud design the major drawbacks of the setup were eliminated, such as a large temperature jump at the interface between the shroud and the thermal plate, and temperature range achievable was improved.
