The Engine's Contribution to Economic Short‐Haul Jet Transport

Improvements in Engine and Power Plant including Reduction in Fuel Consumption, Mechanical Design, Blade Cooling, Lower Vibration, Foreign Object Damage, Oil Consumption, and Reduction in Overhaul Life, all of which can Contribute in Significant Manner to Lower Operating Costs. Recent engine improvements to reduce operating costs are discussed, including examples of features ensuring low vibration level, low metal temperatures of hot end parts, etc. It is predicted that modern techniques will make more major components capable of lasting the whole life span of the engine, facilitating the replacement of present overhaul procedure by sectional overhaul. A possible way to reduce power plant weight is referred to. It is concluded that further advances towards higher engine performance will be accompanied by economies in many other areas of the power unit.
