Abstract

PURPOSE:To twist a blade for a jet engine and alter its pitch angle by forming the blade by material having an expansion coefficient varying upon change of its temparature and heating the blade by heating means. CONSTITUTION:A bimetal 6 is formed by adhering materials 3, 3' having different temperature coefficients to a blade 2 having hollow portion 1 in twisted state, and fixed to inner and outer peripheral ends 4 and 6. A bimetal 6' formed by adhering the same materials in oppositely twisted state is mounted in parallel, and a heater 7 insulated only from the bimetal 6' is wound thereon. The heater 7 is energized from an APU or the like through the shaft of the blade 2. According to this configuration the bimetal 6' can be heated by the heater 7 to thus displace it to thereby control the pitch angle of the blade 2 to thus reliably control it without any consumable part.
