Silnik magnetoelektryczny do pompy paliwa rakietowego kriogenicznego systemu napędowego o małej sile ciągu

The paper presents problems investigated by Mikroma in the project "In Space Propulsion", re-alized within 7' Framework Programme of the European Union. The investigation concerns elaboration of an electric motor to propulsion of a fuel pump in the new concept of cryogenic rocket propulsion with smali thrust force. The problems connected with elaboration of the motor suited to work in cryogenic conditions arę discussed. Chosen results of investigations of the influence of cryogenic temperaturę on the properties of motor manufacturing materials arę shown. Moreover, results of laboratory tests of built prototype motors arę presented.
