Lapátkerék

Lapátkerék is a Hungarian term that literally translates to "propeller wheel" or "propeller". It refers to a type of aircraft propeller that is designed to provide maximum lifting force while minimizing drag. Lapátkerékek are typically characterized by their large, flat blades that are arranged in a circular pattern around the hub.

The lapátkerék design has been used in various aircraft types, including trainers, cargo planes, and attackers. These propellers are known for their high efficiency and durability, making them a popular choice for aircraft operators. Lapátkerék propellers are also relatively easy to maintain and repair, as their simple design allows for straightforward replacement of individual blades.

The name "lapátkerék" is often associated with the Morane-Saulnier MS.230, a French biplane trainer that was powered by a lapátkerék propeller. This aircraft was used extensively in World War II-era training programs and was prized for its stability and maneuverability.

In modern aviation, lapátkerék propellers continue to be used in a variety of aircraft, including homebuilts, ultralights, and experimental planes. Advances in materials science have allowed for the creation of stronger, lighter, and more efficient lapátkerék designs, which provide improved performance and reduced operating costs.
