Spacelab cost reduction alternatives study. Volume 3: Crew training task analysis

The on-orbit phase of flight was analyzed to identify the functions that had to be performed to meet flight objectives. The functions identified were combined into a top-level functional flow diagram (3.0 On-Orbit Operations). Each function, in turn, was analyzed to determine the major activities necessary to perform the function. The activities and activity sequences were presented in second level functional flow diagrams. Each major activity was further analyzed to define the operator tasks that are performed to accomplish that activity. Training analysis worksheets were used to document the analysis of each function down to the task level and provide training requirements data for each task. For Vol. 1, see N76-24315.

Evaluation of textiles proposed for spacecraft crew apparel

Textiles proposed for spacecraft wearing apparel were tested for possible primary irritancy and allergenicity using guinea pigs and human subjects. The materials submitted for testing were: (1) blue, loosely knit fabric of a copolymer of chlorotrifluoroethylene and ethylene (CTFE), (2) a white fabric, 100% cotton double knit, treated with fire retardant Tetrakis (hydroxymethyl) phosphonium hydroxide/ammonia, and (3) a gold colored polyimide fabric. There were no adverse reactions to any of the fabrics.

Protection of crews of spacecraft and space stations

A survey is presented of research on life support for astronauts in emergency situations during flight. Depressurization of the spacecraft cabin, fire, and failure of air regeneration and conditioning systems of manned compartments are among the emergencies considered.

Feasibility study of automatic control of crew comfort in the shuttle Extravehicular Mobility Unit

Computer simulation is used to demonstrate that crewman comfort can be assured by using automatic control of the inlet temperature of the coolant into the liquid cooled garment when input to the controller consists of measurements of the garment inlet temperature and the garment outlet temperature difference. Subsequent tests using a facsimile of the control logic developed in the computer program confirmed the feasibility of such a design scheme.

Skylab 4 crew observations

Comments on food, exercise, scheduling, medical training, the effect of fluid shift, and vestibular phenomena are briefly reported. A ballistocardiographic effect of around 60 beats per minute was observed several times for the whole Skylab cluster. Also experienced were light flashes that were well correlated with the South Atlantic anomaly.

Skylab 2 crew observations and summary

Signs and symptoms experienced during weightlessness ranged from a sensation of fullness in the head to a strange body posture and the sensation of fluid drainage out of the legs. There was no vestibular sense of the upright whatsoever unless the crewmember happened to look at the earth; motion sickness was not a clinical problem. The ability to maintain physical fitness through exercise and the caloric demand remained just about the same as they do on the ground after initial adjustment.

Analysis of the Skylab flight crew health stabilization program

Isolation periods were established prior to launch as well as postflight in order to reduce the number of infectious illness contacts between crewmen. The most frequently reported illness contacts were upper respiratory infections. Enteric illnesses represented the next most common illness, but these were relatively rare compared to upper respiratory infections.

Basic results of the medical research conducted during the flight of two crews on the Salyut-5 orbital station

The study of the effect of space factors, especially weightlessness, on man, taking into account prophylactic measures and devices to counteract that effect was part of the program for two flights on the Salyut 5 orbital station. Information from the equipment on board was transmitted telemetrically including: an electrocardiogram; a sphygmogram of carotid and femoral arteries; a kinetocardiogram; a tacho-oscillogram of the humeral artery, perimetric oscillations of the femur, venous pulse and pressure in the jugular veins, vital capacity of the lungs, respiration rate and lung ventilation. Stress factors, metabolism, biological and bacteriological and other tests were included. A comparison was made between these data and pre- and postflight test result.

Methods for microbiological and immunological studies of space flight crews

Systematic laboratory procedures compiled as an outgrowth of a joint U.S./U.S.S.R. microbiological-immunological experiment performed during the Apollo-Soyuz Test Project space flight are presented. Included are mutually compatible methods for the identification of aerobic and microaerophilic bacteria, yeast and yeastlike microorganisms, and filamentous fungi; methods for the bacteriophage typing of Staphylococcus aureus; and methods for determining the sensitivity of S. aureus to antibiotics. Immunological methods using blood and immunological and biochemical methods using salivary parotid fluid are also described. Formulas for media and laboratory reagents used are listed.

Salyut-6--Soyuz-29: Our commentary, the crew and the station

A newspaper article written by an assistant flight director which stresses the importance of cosmonaut training is presented. The preliminary stage of training is discussed, and the training of a crewmaker on a real spacecraft is briefly covered. The success in training foreign cosmonauts by Soviets is also discussed. The author feels that training is even more important today than it was seven or eight years ago because of the increased complexity of the experiments and the length of time a cosmonaut spends in space now.

Advanced crew station concepts, displays, and input/output technology for civil aircraft of the future

Current efforts on a new Cockpit Avionics Research program are described. The major thrusts of the program presented include: a comparative analysis of advanced display media and development of promising selected media, development of flight display generation techniques, and identification and development of promising I/O technology. In addition, the advanced integrated display concepts described include a 'tunnel in the sky' display and a traffic situation display with associated keyboard. Finally, the Cockpit Avionics Research program is summarized, future research plans are presented, and the need for an expanded program is discussed.

The crew activity planning system bus interface unit

The hardware and software designs used to implement a high speed parallel communications interface to the MITRE 307.2 kilobit/second serial bus communications system are described. The primary topic is the development of the bus interface unit.

The morale climate of the crew (from observations of a submarine doctor)

Personnel interrelationships as affected by sociopsychological compatibility are examined. Practical examples are cited. The principle of complementary temperaments is explored. Stress is laid upon the need for creating conditions that will permit personnel to deal with compatibility problems during the prevoyage preparation period and especially during the confining conditions of a long voyage.
