rahtilentokone

Rahtilentokone, also known as a glider, is an aircraft that does not have an engine or other means of propulsion. Instead, it relies on the forces of lift, weight, thrust, and drag to stay airborne. Gliders are typically launched by being towed behind a powered aircraft, or by being winched up to a certain altitude. Once airborne, the pilot uses the wind and their skill to control the glider's flight path.

Gliders are used for recreational flying, as well as for competitive purposes. They are also used for scientific research, such as studying atmospheric conditions and measuring air pollution. Gliders are typically made of lightweight materials, such as aluminum or composite materials, to minimize weight and maximize lift.

There are several types of gliders, including sailplanes, which are designed for long-distance flight, and acrobatic gliders, which are designed for performing aerial maneuvers. Gliders are also used for paragliding and hang gliding, which are recreational activities that involve flying a lightweight, flexible wing.

Gliders are an important part of aviation history, and they continue to be used today for a variety of purposes. They are a testament to the principles of flight and the skill of the pilot.
