Unpowered miniature aircraft, typically constructed from lightweight materials like balsa wood, tissue paper, and plastic, are launched into the air without any external control system. Their flight paths are determined by inherent design characteristics, including wing shape, dihedral angle, and weight distribution, as well as environmental factors like wind currents and thermals. A classic example is a simple glider launched by hand.
These models offer a tangible connection to the principles of aerodynamics and flight. Building and launching them provides a hands-on learning experience, fostering an understanding of how design choices influence flight behavior. Historically, such models played a crucial role in the development of aviation, serving as early testbeds for innovative designs and concepts. They continue to be valued for recreational enjoyment and educational purposes, offering a readily accessible entry point into the world of flight.
