" GAS turbines are on their way into road transport. They can and will beat the Diesel engine in many important respects," Mr. W. E. P. Johnson, managing director of Power Jets (Research and Development), Ltd., told members of the Society of Engineers in London, on Monday.
I deny the dogma that they will he uneconomic in fuel," he said. " This dogma pre-supposes a limitation (that of bad part-load performance) which is not inherent. I expect soon to see a gas turbine yielding good efficiency at 15 per cent. to 20 per cent. on its full power and only slightly less efficiency at 100 per cent. It will be—as I expect most fairly small units will be—a centrifugal-centripetal machine.
