Definitions

  • This latter is constructed of an electrically conducting metal alloy of SME known type such as a beta aluminium bronze, and is able to expand on temperature increase of the engine 2 to selectively assume a plurality of predetermined shapes, depending on its instantaneous temperature.
  • the element 20 can lengthen progressively in the direction of the helix axis as its temperature increases beyond ambient.
