Analysis of the performance of an aircraft powered by hybrid propulsion

Abstract

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.

Analysis of simulated dynamic loads of a ship propulsion system of a non-conventional power system

“…On the plus side, fuel cells have a much higher energy density and high energy efficiency than batteries. Given these advantages, fuel cells themselves as well as hybrid systems have a promising future in marine applications [21,22,23]. One example of a hybrid system is the use of a PEMFC cell in a propulsion system in which an electrochemical battery can be recharged from a fuel cell (Fig.…”

Exhaust emissions from a jet engine powered by sustainable aviation fuel calculated at various cruising altitudes

“…Aviation organizations have been trying to solve the problem of growing CO 2 emissions from the aviation sector for years. Greenhouse gases are not the only pollutants emitted by aircrafts, there are also pollutants such as nitrogen oxides, carbon monoxide, hydrocarbon, sulfur oxides, particulate matter and others [12,18]. There are many solutions to reduce the impact of the aviation sector on the environment, for example, the development of electric propulsion, changes in the construction of the engines to reduce noise, more sustainable flight routes, and more ecological taxiing [7].…”
