Analysis of the performance of an aircraft powered by hybrid propulsion

Majka Andrzej, Muszyńska-Pałys Jagoda

Combustion Engines

2023

R. 62, nr 2

45--51

Travel is an inseparable part of human life. It is connected not only with private life but also with business life. People want to travel more, farther and faster. That is why air transport is currently one of the fastest-growing areas of passenger transport, and airlines carry more and more passengers from year to year. Due to the growing negative impact of air transport on the natural environment, research aimed at the development of technologies to reduce the negative impact of air transport is becoming more and more important. One of the possibilities for improving the situation is the use of alternative energy sources, limiting the emission of greenhouse gases into the atmosphere. The paper aimed to analyze the meaningfulness of replacing the classic power unit in a light transport aircraft with a hybrid, combustion-electric power unit. Analyzes were made with the use of simulation methods for the PZL M-28 aircraft.

Electric aircraft - present and future

Nagy Andras

Production Engineering Archives

2019

Vol. 23

36--40

In this paper, an outlook about the present of electrical aviation is given. The relatively small energy density of current battery technologies is adequate to build usable electric car, but not suitable for electric aircraft. Because of the very limited amount of energy available on-board, a couple of percent in efficiency can give significant increase in range and flight time, hence the development of more efficient propulsion system and E-motor is as important as the development of battery technologies. Current research results at the University of Dunaujvaros show, that building E-motors from amorphous materials is possible, and can easily increase the efficiency of high speed E-motors.

Analysis of the availability of aircrafts with alternative propulsions

Combustion Engines

2019

R. 58, nr 4

220--225

Global air traffic doubles every 15 years. Therefore, aviation emission grows as well. It is advisable to look for an alternative air-crafts’ propulsion for both commercial and general aviation (usually flying closer to the ground). There are many prototypes proposed by homemade projects, through companies wanting to extend their offer. There are also several more advanced constructions ready to self-set or serially produced. In the article the main topic are electric aircrafts as an example of possibility to reduce the toxic com-pounds emission. According to the analysis some of companies specializing in unmanned aircraft production, starting to expand their business with manned products. In the article, analyses of electric aircrafts different models, which are available on market and present-ed the comparisons characteristics based on e.g. cruise speed, range for every model or charging time were made and conclusions about alternative aircraft propulsions, were made.
