Overview
In the history of saturation diving Czechoslovakia occupied the third position in nineteen sixties after France and the USA. The record dive of the Permon project (102 h in 25m depth) was made in 1967.
The Hydronaut Project connecting the saturation stay with a simulation in outer space was published in 2010. A living module is being completed and the health and psychical state of five divers was completed, while three of them are to stay in the depth for 7 days. The limit of the mission depth is related to the risk of cumulative oxygen lung toxicity. In conditions of breathing air, the module may be maximally immersed to 20 m below surface. In view of the dissolved gases in tissues, maximum change of depth in the 10 m range must be observed for the way out of the module. The final decompression could last about 35 h with 12 stops graduated by 1.5 m.
A final goal of the Hydronaut Project is to investigate the effect of stress load during the stay in a closed, isolated, limited and dangerous environment. The authors are planning introduce a course of special physical and psychological preparation, which will make use of the knowledge of the saturation diving as well as from the analogous space studies. The main ambition of the project is to contribute its knowledge and experience to the area of European pilot spaceflights.
