Main problems of the Russian Orlan-M space suit utilization for EVAs on the ISS.
In the recent years the Russian Orlan-M space suits have been improved as applied to their operational requirements for the ISS. A special attention is paid to enhancement of EVA crew efficiency and safety. The paper considers the main problems regarding specific features of the Russian space suit operation in the ISS, and analyses measures on their solution. In particular, the problems associated with the following are considered: enhancement of the anthropometric range for the EVA crewmembers; use of some US EMU elements and unified NASA equipment elements; Orlan-M operation support in the wide range of the ISS thermal conditions; use of Simplified Aid For Extravehicular activity Rescue (SAFER) designed as a self-rescue device, which will be used for an EVA crewmember return in the event that he (she) breaks away inadvertently from the ISS surface. The paper states the main space suit differences with reference to solution of the above problems. The paper presents briefly the design of space suit arms developed for crewmembers with small anthropometric parameters, as well as peculiarities and test results for the gloves with enhanced thermal protection. Measures on further space suit development with the purpose to improve its performances are considered.
