| Abstract: |
| Special requirements of environmental control system on helicopter were stated. Two kinds of simplified air cycle refrigeration systems that can be applied were described. The working principles of the simplified low-pressure dewater system and the high-pressure dewater system were discussed. Finally the performances were calculated and analyzed. The results show that the refrigeration capacities of these two systems are 4.13kW and 5.56kW respectively. Injected high-pressure dewater system can fully use the bleeds to gain more refrigeration capacity and has less weight relatively. |
