Structural design of integral tankage for advanced space transportation systems

Fully reusable launch vehicle concepts being studied for post-Shuttle era transports present major challenges for the structural design of large propellant tankage. The dominant structural elements are internal tankage for both cryogenic and non-cryogenic propellants which must operate in a broad range of thermal environments while meeting requirements for low weight and reusability. Several approaches to integral tank design are discussed and an analysis of a hot structure honeycomb sandwich tank for a circular body vehicle is presented.

Evaluation of Space Transportation System (STS) OV-102 orbiter payload bay acoustic environment

This report presents the results of a statistical analysis and evaluation performed by the Mechanical Engineering Branch (Code 731) on the payload bay internal acoustic data measured on the STS-1 through STS-4 flights. The results are used as a basis for developing the required baseline acoustic environment specification to be used in establishing design and test criteria for STS payloads and components.

Analysis of physical exercises and exercise protocols for space transportation system operation

A quantitative evaluation of the Thornton-Whitmore treadmill was made so that informed management decisions regarding the role of this treadmill in operational flight crew exercise programs could be made. Specific tasks to be completed were: The Thornton-Whitmore passive treadmill as an exercise device at one-g was evaluated. Hardware, harness and restraint systems for use with the Thornton-Whitmore treadmill in the laboratory and in Shuttle flights were established. The quantitative and qualitative performance of human subjects on the Thorton-Whitmore treadmill with forces in excess of one-g, was evaluated. The performance of human subjects on the Thornton-Whitmore treadmill in weightlessness (onboard Shuttle flights) was also determined.

Space Transportation System Mission STS-7

The second flight of Challenger was another exceptional flight in that 11 major objectives were accomplished. The TELESAT-F and PALAPA-B1 were deployed exactly on time. The SPAS-01 attached and detached operations went extremely well despite some heating problems with the SPAS. The OSTA-2 experiments for the Material Experiments Assembly and Material Wissenschaftliche Autone Unter Schwerelosigkeit were activated as planned with no indications of anomalies, and the MLR and CFES experiment packages in the middeck area were operated by the crew as planned. Ninety-six percent (56 of 58) of the assigned flight test objectives were completed. The turnaround time was accomplished in the least time to date (only 99.5 hours) and the return to KSC was completed with a total of only 5 days loss of program time.

Induced Environment Contamination Monitor (IECM), air sampler - Results from the Space Transport System (STS-2) flight

An investigation involving sampling the rapidly changing environment of the Shuttle cargo bay is considered. Four time-integrated samples and one rapid acquisition sample were collected to determine the types and quantities of contaminants present during ascent and descent of the Shuttle. The sampling times for the various bottles were controlled by valves operated by the Data Acquisition and Control System (DACS) of the IECM. Many of the observed species were found to be common solvents used in cleaning surfaces. When the actual volume sampled is taken into account, the relative mass of organics sampled during descent is about 20 percent less than during ascent.

National Space Transportation Systems Program mission report

The major activities and accomplishments of this first Spacelab mission using Orbiter vehicle 102. The significant configuration differences incorporated prior to STS-9 include the first use of the 3 substack fuel cells, the use of 5 cryo tanks sets and the addition of a galley and crew sleep stations. These differences combined with the Spacelab payload resulted in the heaviest landing weight yet flown. The problems that occurred are cited and a problem tracking list of all significant anomalies tht occurred during the mission is included. Scientific results of experiments conducted are highlighted.

Results of studies on advanced winged space transportation systems

Various winged spaceplane concepts which appear viable as the post-Shuttle generation of launch vehicles are reviewed. The designs all yield improvements in size and mass compared to the STS, provided certain emerging technologies are successfully applied. Single-stage-to-orbit (SSTO) vehicles would burn LOX/LH fuels in SSME-derived engines with two position nozzles. SSTO could be realized in either vertical or horizontal take-off configurations, but all would have 29,500 kg payload capacities and horizontal landing capabilities. Consideration is given to alternative fuels, the effects of adding air-breathing engines, various ways of attaching and deploying payloads, containing the fuels and providing thermal protection during reentry. It is found that similar technology advances are needed for all the concepts.

National space transportation systems planning

In the fall of 1984, the DOD and NASA had been asked to identify launch vehicle technologies which could be made available for use in 1995 to 2010. The results of the studies of the two groups were integrated, and a consumer report, dated December 1984, was forwarded to the President. Aspects of mission planning and analysis are discussed along with a combined mission model, future launch system requirements, a launch vehicle planning background, Shuttle derivative vehicle program options, payload modularization, launch vehicle technology implications, a new engine program for the mid-1990's. Future launch systems goals are to achieve an order of magnitude reduction in future launch cost and meet the lift requirements and launch rates. Attention is given to an advanced cryogenic engine, advanced LOX/hydrocarbon engine, advanced power systems, aerodynamics/flight mechanics, reentry/recovery systems, avionics/software, advanced manufacturing techniques, autonomous ground and mission operations, advanced structures/materials, and air breathing propulsion.
