EVA Suit
Revised : 17 Sep 2022
An EVA suit consists of the following 12 part components:
| Parts |
|---|
| counter pressure suit |
| coveralls |
| eva pads |
| eva backpack |
| eva antenna |
| eva battery |
| eva boots |
| eva gloves |
| eva helmet |
| eva radio |
| suit heating unit |
| helmet visor |
Since an EVA suit is treated as an Equipment and is subject to reliability factors.
The following type of malfunctions may happen to an EVA suit :
| Malfunctions |
|---|
| Air Leak |
| Water Leak |
| Heating Unit Failure |
| Suit Tear |
| EVA Radio Failure |
| Electrical Short |
Players may choose to speed up the production of these EVA related parts as seen fit during the simulation by elevating the need for EVA related repairs.
| Level | Pressure in kPa | Mass in kg |
|---|---|---|
| Full Tank of O2 | 66.62 | 1 |
| Target O2 | 20.7 | 0.3107 |
| Nominal O2 | 17 | 0.2552 |
| Minimum O2 | 11.94 | 0.1792 |
In a 3.9 liter system, 1 kg of O2 can create 66.62 kPa partial pressure.
To supply a partial O2 pressure of 20.7 kPa, one needs at least 0.3107 kg O2
With the minimum required O2 partial pressure of 11.94 kPa (1.732 psi), the minimum mass of O2 is 0.1792 kg.
The interior of the EVA suit's maintains a nominal pressure of O2 at 17 kPa (2.47 psi). This low pressure environment allows for more optimal use of resources and design specifications and corresponds to having just 0.2552 kg of O2 released from the tank to the interior of the EVA suit.
