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.

The main purpose of present article is to present the burner rig station newly developed at the Rzeszow University of Technology in Poland. The burner rig is dedicated to operate on fuels rich in hydrogen. The burner rig is able to operate with fuels with hydrogen content up to 50 volume %. A detailed description of burner rig construction is presented. Moreover a mathematical model predicting temperature distribution within the combustion chamber is presented. The obtained results showed a good insulation of burner rig construction leading to the temperature gradient from 1674℃ in the burner rig to 214℃ on steel housing.

Głównym celem niniejszego artykułu jest przedstawienie stanowiska palnikowego nowo opracowanego na Politechnice Rzeszowskiej. Palnik przeznaczony jest do pracy na paliwach bogatych w wodór. Palnik może pracować z paliwami o zawartości wodoru do 50% obj. Przedstawiono szczegółowy opis budowy stanowiska palnika. Zaprezentowano także model matematyczny przewidujący rozkład temperatury w komorze spalania. Uzyskane wyniki wykazały dobrą izolację konstrukcji palnika, co doprowadziło do powstania gradientu temperatury od 1674°C w korpusie palnika do 214°C na obudowie stalowej.
