ENGINES

Radial engine

  1. Most gas turbine engines are axial: the compressed air in them moves in a linear direction. In a radial turbine engine, the air moves peripherally as in a centrifuge. Although the axial turbines are used where large amounts of power are required, R. J. Mowill, Norway, says radial engines could be used at the lower end of the high-power spectrum.
  2. His company has developed a 1.600-horsepower radial engine for ships. Reliability and low maintenance costs combined with smallness of size are advantages that make the engine competitive, he says. A key factor in making it more attractive is that the firm has been able to increase the engine’s compression ratio.
  3. All of the components in the engine are designed in order to cut down maintenance problems. Sliding bearings are used, for example, to reduce friction and to cope with gyroscopic forces in heavy seas.

Ceramic turbine engine

  1. The gas turbine has been considered a challenger to the internal combustion engine in cars. Auto engineers say that one way to make it competitive is to make it out of ceramics, which would permit higher turbine operating temperatures and therefore greater efficiency and fuel savings. Such a turbine would also be cheaper.
  2. Arthur F. McLean of the Ford Motor Co. sees silicon carbide and silicon nitride as prime candidates. Although these dense, low-cost materials show great heal and corrosion resistance, one drawback is that they can be brittle. This problem can be overcome, says McLean, by unique design to support ceramic components with metal housing.
