"IBM Mobile Room Lends Flexibility to Apollo Saturn Unit Fabrication."

"Methods for cleaning electronic components and subassemblies."
In describing the cleaning of electronic components and subassemblies, it must be taken into consideration that each part to be cleaned presents an individual problem. The method of cleaning must be tailored to the type of part to be cleaned as well as to the type of soil to be removed. This paper reviews some of the methods used in cleaning electronic arts, particularly printed circuits, as well as other critical hardware which is used in support of electronic assemblies. Some of the methods covered include the use of abrasives, acids, solvents and alkalies, and the employment of these in combination with ultrasonic and other automatic systems. The clean room in use at IBM Huntsville is described briefly, along with the solutions and solvents used in cleaning electronic and supporting parts. Cleanliness- requirements for the area and the materials, together with procedures for meeting them give added emphasis to the critical nature of today's contamination control programs. The paper concludes with a summary of the cleaning procedures and the cleanroom benefits to be obtained by using present day technologies to improve them. -

"The instrumentation of space vehicle in connection with the successful Saturn flight tests."
Presented on September 21, 1962, at the Eleventh Tagung Der Deutchen Raketen - Gesellschaft, Koblenz, West Germany. Instrumentation sf the Saturn space vehicle represents a considerable effort during the development phase, for proper design evaluatian of this new configuration, its propulsion system, and its structure and control characteristics, an unprecedented number of measurements are required to be carried onboard and to be recovered, These measurements are expected to work properly and to furnish the design engineer with information that is not available by ground testing, -
"Altitude Simulation in Saturn SIV Space Testing."
This paper was presented to the Society of Automotive Engineers. The abstract reads, "The Douglas Aircraft Company has been involved in testing the Saturn SIV stage at the Sacramento Test Center for the past two years. The propulsion system for the SIV stage consists of six (6) Pratt & Whitney Aircraft Company rocket engines which are designed specifically for high altitude start and operation. During static firing tests of this engine at sea level, a steam jet ejector in combination with a diffuser, are used to simulate altitude conditions. The intent of this paper is to examine the performance of this altitude simulation system, and to discuss problems encountered in making it operational." -

"IU/S-IVB Forward Skirt Orbital and Translunar Thermal Analyses."
This report determines the maximum and minimum solar and terrestrial thermal energy incident and absorbed by Saturn IB/V vehicles in earth orbit and translunar travel. The influence' of this external energy on the Instrument Unit Thermal Conditioning System performance, and consequently its adequacy to maintain the electronic packages at acceptable temperature limits is ascertained. Conclusions are: a) Methanol/water coolant temperature will deviate from 111 specifications only during translunar cold flights. However, adequate thermal conditioning of the electronic equipment would still be maintained. b) Instrument Unit missions exceeding 6 1/2 hours, or electronic packages heat dissipation magnitudes lower than 3 kw or higher than 8.5 kw, should be reviewed to ascertain thermal compatibility. -
"Saturn V ground winds program."
The concept on Saturn V was to "budget" an amount for the dynamic portion of the wind load as a factor on the steady state drag. Wind tunnel tests paralleled the development and fabrication phases. The results indicated that the system was unable to withstand the design winds; thus, a decision was made to implement a viscous damper "fix" on the facility vehicle at the Kennedy Space Center. Damping tests in the Vertical Assembly Building (VAB) will have been completed and response tests on the pad will be in progress at the time of this symposium. This paper will present the history and status of this program to date. -

"Furnace Brazing of Liquid Rocket Thrust Chambers."
Brazing as a technique for joining metal parts has been utilized for centuries. Industry, however, has only begun to use it on a wide scale in the last twenty years. The rapid growth of brazing has been a result of consumer and military demands Tor products of lighter weight, less expense, and higher performance. Today, brazing is one of the most widely used fabrication techniques in the production of liquid rockets, gas turbines, refrigerator and other types of heat exchangers, automobile parts, vacuum tubes, and many nuclear products. -

"Sensitivity of rocket engine stability to propellant feed system dynamics."
Because of the increased reliability required of rocket systems in their more recently assigned missions, previously acceptable design features must be reappraised ad refined. In the region of rocket engine system stability, the probles is centered in two areas, the combustor and the propellant feed system The principal interest of this paper lies in the coupling that occurs between the feed system and combustion dynamics, often termed a "buzzing" instability then the dymics are characterized by periodic pressure oscillations in the range of 200 to 1000 cps appearing in the combustion chamber and' the feed system. -
"The reliability of the all-up concept."
Prepared for George C. Marshall Space Flight Center, Huntsville, Alabama under contract NAS8-11087. Publication No. 294-02-12-440.

Marshall Space Flight Center (MSFC) requested ARINC Research Corporation to make a brief study of the reliability aspects of the All-Up concept. Under the requirements of Task 294-02 of Contract NAS8-11087, the study included a comparison between the reliability of the first Saturn V vehicle if All-Up, and its reliability with dummy upper stages. -
"Test procedure validation by computer simulation."
Digital computer simulation of the Saturn I Instrument Unit electrical networks was accomplished using the Discrete Network Simulation programs. The schematics were analyzed and a logic model prepared which consisted of a series of Boolean equations. The test procedures, which are written in the Acceptance, Test, or Launch Language (ATOLL), consist of a sequential set of computer instructions for the RCA llOA checkout computer to control the operation of the electrical networks. The procedures also contain the predicted results for each operation. The driving functions for the simulation of the model are generated from the ATOLL test tape by the Input Generator Program. The time sequenced operation of the networks is indicatedby the output from the simulation program in addition to the number of times each component in the system changes state. The results of the simulation are compared to the test procedure predictions on the ATOLL tape by the Comparator Program and any differences are listed. The Comparator Program also lists any component which did not change state at least once. -
