Leanchers

Leanchers, also known as lean-to launchers, are a type of small, portable catapult designed to launch small projectiles, typically model rockets or other lightweight objects. They are often used in educational settings to teach principles of physics, engineering, and aerodynamics. Leanchers are typically made of lightweight materials such as aluminum or plastic, and they operate on the principle of a lever arm, where a small force applied to a long arm can generate a large force at the other end.

The design of a leancher usually consists of a base, a lever arm, and a release mechanism. The base provides stability and support, while the lever arm allows the user to apply force to the projectile. The release mechanism is typically a spring-loaded system that stores energy and then releases it to launch the projectile. Leanchers can be manually operated or powered by a motor, depending on the design and intended use.

Leanchers are popular among hobbyists, educators, and enthusiasts due to their simplicity, affordability, and educational value. They can be used to launch a variety of projectiles, including model rockets, small balls, or even small animals in controlled environments. However, it is important to note that the use of leanchers should always be done with caution and under proper supervision, as they can generate significant force and may pose a risk to users and bystanders if not handled correctly.
