A plane that has no motor is a glider.
Understanding Gliders
Gliders are a type of aircraft designed to fly without the use of an engine. Instead of relying on a motor for propulsion, they utilize natural forces to stay airborne and navigate through the air. According to information, "Gliders are airplanes without engines. They derive thrust technically as a resultant force of Gravity and weight."
How Gliders Work:
- Lift: Gliders use their wing shape to generate lift as air flows over them.
- Gravity and Weight: Gliders technically derive thrust from a resultant force of gravity and weight.
- Soaring: Skilled glider pilots can stay aloft for extended periods by finding and utilizing rising air currents, such as thermals or ridge lift.
- Launch: Gliders are typically launched into the air by being towed behind a powered aircraft or by using a winch system.
Examples of Gliders:
- Sailplanes (High-performance gliders used for soaring competitions).
- Hang gliders (Foot-launched gliders).
- Paragliders (Similar to hang gliders but with a fabric wing).
Key Characteristics of Gliders:
| Feature | Description |
|---|---|
| Engine | None |
| Propulsion | Relies on lift, gravity, and weight instead of engine power |
| Launch Method | Towed by aircraft, winch, or foot-launched |
| Purpose | Recreation, competition, or research |
In summary, a glider is the type of aircraft that perfectly fits the description of a plane without a motor.
