sailplane

Definition of Sailplane

A sailplane is a type of unpowered fixed-wing aircraft that is capable of maintaining prolonged flight without the use of an engine. Also known as a glider, this aircraft relies solely on natural thermals and air currents for its propulsion.

Unlike a traditional motorized airplane, a sailplane is designed with an elongated and slender fuselage, which allows it to glide smoothly through the air with minimal resistance. It has a large set of wings that span across the length of the aircraft and provide lift, and a tail section that helps with maneuverability.

Sailplanes are typically launched using a tow rope or winch, or by being released from a high altitude. Once in the air, the pilot must use their knowledge of the surrounding air currents to maintain altitude and maneuver the sailplane.

Sailplanes are often used for recreational purposes, such as soaring and gliding competitions, but they also have practical applications. They can be used for meteorological research or to perform aerial reconnaissance without detection.

Overall, sailplanes are a remarkable example of engineering ingenuity, providing a way for pilots to soar through the air without the need for an engine.
