Simulation Research of Aircraft Piston Engine Rotax 912

Performance simulation of a spark ignited free-piston engine

Free-piston engines are under investigation by a number of research groups worldwide due to potential fuel efficiency and engine emissions advantages. The free-piston engine generator, in which a linear electric generator is fixed to the mover to produce electric power, has been proposed as an alternative prime mover for hybrid-electric vehicles. This paper investigates the performance of a spa...

Aircraft Piston Engine Fault Detection Based on Uniformity of Cylinder Head, Exhaust Gas and Turbochargers Temperatures

Piston engines are effective solution for providing general aviation aircrafts with a small power at acceptable operating and maintenance costs. However, they lack the reliability of turbine engines. Graphic engine monitors may increase operational reliability of piston engines by providing necessary data for the proper engine operation and maintenance. They display and record numerous engine p...

Causes and Trends in Maintenance-Related Accidents in FAA-Certified Single Engine Piston Aircraft

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR P...

Analysis of Piston of Two Stroke Engine

Due to the inherent nature of combustion in the Cylinder of a Conventional Internal combustion engine, stress variation as well as a certain temperature distribution sets up in the entire piston. Analysis of piston is required because of its shape and it is subjected to both structural and thermal loads. In the present study, piston of a two stroke spark ignition internal combustion engine havi...
