Engine Development

Exciting developments have occurred over the past two years in the technological status and production aspects of Stratified Charge Rotary Engines. A program is currently underway for the development, certification and production of a 400 HP aircraft engine in early 1990. The joint program is being conducted by John Deere’s Rotary Engine Division and AVCO Lycoming Williamsport Division. The engine will offer to the General Aviation community Jet-A fuel capability at substantial cost savings, improved altitude capability and lower fuel consumption over turbine power plants. Application to fixed wing and rotary wing aircraft are planned. Other stratified charge rotary engine development work in progress involves ground power units, airborne APU’s, shipboard gensets and vehicular engines, supported by Deere production capabilities and DOD interests. Technology enablement efforts by NASA, aimed at highly advanced output and efficiency are in progress leading toward revolutionary engine capability for aircraft and other applications.

Substantial progress has been made over the past two years in the technological status and production aspects of Stratified Charge Rotary Engines, a new propulsion technology for aircraft of the 1990’s. A 400 HP aircraft engine, designed in cooperation with Avco-Lycoming (during late 1986) is currently undergoing testing at John Deere’s Rotary Engine Division. Current status and design features are reported in this paper and related to overall research and technology enablement efforts toward several families of advanced liquid cooled, turbocharged and intercooled engines over a wide power range for commercial general aviation. Capabilities for high altitude, long endurance, military unmanned aircraft missions are examined. Application to fixed and rotary wing aircraft are planned.

Alternative Power

This paper describes different types of engine used for transportation purposes. Some of the more interesting developments in spark ignition and diesel engines are outlined, but the paper is mainly a review of some of the alternative power plants that have been studied over the past 40 years. These include vapour cycle engines, free-piston engines, compound engines, Stirling engines, gas turbines, stratified charge engines, the catalytic engine, rotary engines and two-stroke spark ignition engines. The paper concludes by discussing possible future developments for some of these alternative engines.

Youth Training

The authors present a detailed case study of the evolution of apprenticeships in German banking over the past two decades to analyze why employers continue to be willing to invest in these programs that provide workers with transferable skills. They explain employers' motivation in terms of two “logics.” Some considerations stemming from the logic of consequences, such as recruitment cost savings and enhanced workplace flexibility, encourage retention of the apprenticeship system. On balance, however, the cost calculus that is at the heart of the logic of consequences would, if unopposed, encourage head-hunting for apprentices trained by other firms, eventually undermining the system. The countervailing logic of appropriateness, however, discourages defections from the system by fostering trust among employers, encouraging new firms to participate in the system, supporting the strong reputational effect associated with training, and creating mechanisms with which banks can have a hand in keeping the system efficient.

Human Factors Research

When General Aviation (GA) pilots encounter unexpected weather hazards in-flight, the results are typically deadly. It is unsurprising that the National Transportation Safety Board repeatedly lists weather related factors in GA flight operations as an unsolved aviation safety challenge. Solving this problem requires multidisciplinary perspectives. Fortunately, in the past several years innovative laboratory research and industry products have become available. This panel discussion brings together Human Factors and Ergonomics researchers and practitioners to discuss and describe the current work and future directions to avoid weather related accidents in GA.
