Study on the optimization of power systems and aerodynamic configuration of vertical takeoff and landing unmanned aerial vehicles

Study on the optimization of power systems and aerodynamic configuration of vertical takeoff and landing unmanned aerial vehicles

Abstract

The study investigates vertical takeoff and landing (VTOL) unmanned aerial vehicles (UAVs), their configuration and powertrain schemes, as well as the efficiency of different types of power systems. A comparative analysis of electric, parallel, and hybrid power systems was performed, and mass characteristics were calculated for missions with a range of 50, 100, and 300 km. It was determined that the hybrid system provides the optimal balance between weight, fuel consumption, and flight duration. The proposed blended-wing-body configuration improves aerodynamic efficiency by 12 % in cruise mode. The use of a hybrid power system allows for a 10–15 % reduction in UAV takeoff weight and an increase in flight duration by up to 25 %. The obtained results can be applied in the design of UAVs intended for monitoring, environmental surveillance, logistics, and rescue missions in challenging conditions.

Досліджуються безпілотні літальні апарати (БПЛА) вертикального зльоту та посадки (ВЗтП), їхні компонувальні та силові схеми, а також ефективність різних типів силових установок. Виконано порівняльний аналіз електричних, паралельних і гібридних силових установок, розраховано масові характеристики для місій дальністю 50, 100 і 300 км. Визначено, що гібридна схема забезпечує оптимальний баланс між вагою, витратою палива та тривалістю польоту. Запропоноване компонування «корпус-крило» підвищує аеродинамічну якість на 12 % у крейсерському режимі. Використання гібридної силової установки дозволяє зменшити злітну масу БПЛА на 10–15 % та збільшити тривалість польоту до 25 %. Отримані результати можуть бути застосовані для проєктування БПЛА, призначених для моніторингу, екологічного нагляду, логістики та рятувальних місій у складних умовах.
