And Planning sailboat , o simply one glider , it is a fixed -wing aerodine (a heavier aircraft than the air), with large wings, normally lacking motor [ first ] . Its support and translation forces come only from the resulting general aerodynamics, as well as those of the other gliders such as paragers and Delta wings. Sharing with them the practice of free flight, this type of aircraft is used in the sport of flight to candle (or volvelism), although it has also been used for other purposes, such as military or research.

Characteristics [ To edit ]

Zugvogel III at Aalen-elchingen, Germany.

A feature is its high distance relationship traveled in the lost height (planning ratio). This feature makes this family of aircraft the most efficient way to fly. This is achieved by opposing minimal resistance to a given support force; That is why they have long and thin wings, and a narrow and aerodynamic fuselage. These properties facilitate ascent thanks to ascending air currents (thermal or dynamic).

There are crew and not crew or radiocontrolled; real size and scale aeromodelos; There are flexible fabric wing (paragliding) or wings of rigid or semi -flexible structures (glider sailboat and delta wing). They are used for the practice of free flight.

Enlarging the image, the instrumentation can be observed in detail.

Although many gliders do not have a motor, there are some who occasionally use them, the so -called motoplaneadores o simply Motor planners . Today, high -performance planters manufacturers frequently offer an option as optional, along with a retraible propeller that can be used to provide flight support. Some are even able to take off by their own means. In other models, the propeller cannot be retracted but the engine can be stopped after takeoff.

Ineling systems [ To edit ]

In flight The procedure is called by which the “take off” glider, which is usually not possible by its own means. The two most frequently used methods are by plane towing or by lathe.

For the trailer, a monomotor light plane is normally used. The tugboat leads to the planner to the desired place and height, where the planner’s pilot unhook the tow rope. To the rope a weaker element is frequently added to ensure that sudden loads do not harm the tugboat.

During the trailer, the planner’s pilot must be maintained in one of two positions behind the tugboat: below the turbulence generated by the tugboat or above it; The latter is the most common. A less used variant is the simultaneous trailer of two gliders by a tugboat, using a shorter rope for the glider that is in the upper position.

In this case, an engine on land mounted on a mobile device normally, pulls a large length cable at which the glider is hooked. The takeoff is very fast and with a high climbing angle; The disengagement is done automatically, for safety, since the towing hook in the glider is different from the trailer plane.
