Unpowered miniature plane, sometimes constructed from light-weight supplies like balsa wooden, tissue paper, and plastic, are launched into the air with none exterior management system. Their flight paths are decided by inherent design traits, together with wing form, dihedral angle, and weight distribution, in addition to environmental elements like wind currents and thermals. A basic instance is an easy glider launched by hand.
These fashions supply a tangible connection to the rules of aerodynamics and flight. Constructing and launching them offers a hands-on studying expertise, fostering an understanding of how design selections affect flight conduct. Traditionally, such fashions performed a vital function within the improvement of aviation, serving as early testbeds for progressive designs and ideas. They proceed to be valued for leisure enjoyment and academic functions, providing a readily accessible entry level into the world of flight.
