| 7 | The Thermal Testing test is directed by the test leader Christiaan van Ommeren. The thermal testing | ||
| 8 | contains different sections. Firstly the head and cold resistance of the suit are tested. Also tests with | ||
| 9 | the open PLSS (portable life support system) are being taken. Furthermore tests with physical | ||
| 10 | exercises have to be done by the analog astronaut (wearing the suit) under different circumstances. | ||
| 11 | The temperatures of the range between -110° and +35° Celsius. Potential hazards within the tests are | ||
| 12 | condensation, cracking due to thermal contraction/expansion, under-cooling and fire. The thermal | ||
| 13 | test involves seven Subtests (A-G). | ||
| 14 | |||
| 15 | **Subtest A: **The PLSS is tested at a temperature of -10° Celsius (both, open and closed). The | ||
| 16 | temperature of the helmet and the PLSS are checked. As well as the communication system and the | ||
| 17 | sensor functionality. The minimal needed fan speed is measured. Subtest A has a duration of approx. | ||
| 18 | 8 minutes. | ||
| 19 | |||
| 20 | **Subtest B: **Same procedure as in Subtest A except the temperature is set to -50° Celsius. Subtest B | ||
| 21 | has a duration of approx. 8 minutes. | ||
| 22 | |||
| 23 | **Subtest C: **Same procedure as in Subtest A except the temperature is set to -110° Celsius. Subtest C | ||
| 24 | has a duration of approx. 8 minutes. | ||
| 25 | |||
| 26 | **Subtest D: **This test serves to the warm up the suit again for the Analog Astronaut. From -110° | ||
| 27 | Celsius the suit is first transported to -50° then to -10° Celsius and finally out of the chambers (20° | ||
| 28 | Celsius, room temperature). Also this test is used to evaluate possible micro fractures on the visor, | ||
| 29 | metals or textile tissues. Furthermore the communication system and the sensor functionality are | ||
| 30 | checked. This test has a duration of approx. 47 minutes. | ||
| 31 | |||
| 32 | **Subtest E:** This test contains physical exercises of the Analog Astronaut at a temperature of 25° | ||
| 33 | Celsius. Such as low energy (standing), medium energy (walking) and high energy (pick up something | ||
| 34 | and put it back and repeat). During the test, helmet temperature and humidity are checked | ||
| 35 | continuously. This test has a duration of approx. 19 minutes. | ||
| 36 | |||
| 37 | **Subtest F:** Same procedure as in Subtest E except the temperature is set to 30° Celsius. Physical | ||
| 38 | exercises such as low energy (standing), medium energy (walking) and high energy (pick up | ||
| 39 | something and put it back and repeat). During the test, helmet temperature and humidity are | ||
| 40 | checked continuously. This test has a duration of approx. 19 minutes. | ||
| 41 | |||
| 42 | **Subtest G:** Same procedure as in Subtest E except the temperature is set to 35° Celsius. Physical | ||
| 43 | exercises such as low energy (standing), medium energy (walking) and high energy (pick up | ||
| 44 | something and put it back and repeat). During the test, helmet temperature and humidity are | ||
| 45 | checked continuously. This test has a duration of approx. 19 minutes. |
