РАСЧЕТ ДАЛЬНОСТИ ПОЛЕТА ЭЛЕКТРИЧЕСКОГО САМОЛЕТА

Abstract

A large number of leading aircraft and engine companies are showing increasing interest in developing projects that re-duce the negative impact of aviation on the environment. One of the promising areas is the electrification of aircraft at different levels: from individual engine systems to fully electric power supply of the aircraft. To determine the possibility of using electric technologies, a method for calculating the flight range of an electric aircraft has been developed, it is based on the calculation of the required power for the rotation of the propeller, which creates the necessary thrust for flight during the entire flight cycle. Calculations were carried out on the examples of two aircraft: the fully electric Eviation Alice aircraft and the short-haul passen-ger aircraft IL-114-300. The methodology can be considered reliable, for the Eviation Alice aircraft the flight range and reserve flight time declared by the developer were confirmed. However, at the current stage of technology development, it is impossible to create a fully electric power plant for a short-haul passenger aircraft that will provide the required parameters, like the IL-114-300 aircraft with rechargeable batteries. To create an electric power plant for a passenger aircraft, it is necessary to increase the specific energy consumption by more than 3 times compared to modern indicators.
