Design and Construction of Radio-Controlled Glider with Renewable Energy Capabilities

Abstract

Thermal columns are a meteorological phenomenon which is frequently used by birds to rise without requiring wing power. Imitating this behaviour with an aircraft can utilize this lift to provide energy for the electrical components of the system. In this study, a radio-controlled glider with a built-in wind turbine and generator was designed and constructed. The generator is intended to provide renewable energy during glides, especially when thermal columns are harnessed. The glider was constructed using composite materials, which combine a high level of strength together with light-weight, improving energy efficiency. Turbine design was implemented using a duct-fan model which increases air flow to the generator. Test flight measurements indicate efficient battery recharging can be obtained during glides. The system may be implemented in manned or unmanned gliders, for agricultural, civil, or security uses, such as unmanned surveillance airplanes.
