Indications for Increased Cosmic Radiation in the Interplanetary Space
A simple connection was experimentally found between the amplitudes of world-wide variations of cosmic ray intensity and the dependence of this intensity on geomagnetic latitude. It turns out that these variations can be interpreted as changes of an elect

Zusammenfassung - Resume
Flight Experiments about Human Reactions to Accelerations which are Followed or Preceded by Weightlessness. During the launching phase of manned space or orbital
flight, any subject will be exposed to rather high accelerative forces. After burn-out the subject will recover from this stress not in a normal G field, but in the weightless state. On the other hand, the re-entry decelerations will act on a subject who has been exposed for extended periods to weightlessness. The author conducted flight experiments in jet aircraft, which simulated these "Pre-weightlessness" and "Post-weightlessness" accelerations. By pull-outs and tight diving spirals, subjects were exposed to positive accelerations of up to 6.5 G for periods of as much as one minute, which produced in several cases a marked "black-out". This acceleration stress was preceded or followed by KEPLERian subgravity trajectories. It was shown that these alternations of acceleration and the weightless state decrease the acceleration tolerance of the subject and the efficiency of the physiological recovery mechanisms. The implications for planning of manned space flight are, first, that thrust values and re-entry profiles must take the lower acceleration-tolerance into consideration, and second, that adequate G protection must be designed for the pilot, to prevent dangerous effects of unavoidable high accelerations.
