Description

Fighter shooting coordinator principle presentation device

Technical Field

The utility model relates to the technical field of demonstration teaching aids, in particular to a device for demonstrating the principle of a shooting coordinator of a fighter plane.

Background

The simulation demonstration is an important teaching means for the museum to simulate and reproduce the principles of certain devices and enhance the intuitive and perceptual knowledge of visitors. Specifically: for objective reasons, museums cannot graphically describe some important phenomena occurring when devices are operated, and watching principle videos lacks substitution feeling. Therefore, simulation demonstration can simulate and reproduce some important phenomena, concepts and definitions when the device operates through a simulation model, and is introduced by combining with language, so that the device is convenient to display.

The aircraft shooting coordinator can enable an aircraft-mounted gun of an aircraft to act in coordination with an aircraft propeller when the aircraft gun is in a gun-starting state, so that ejection of a bullet onto the propeller blade is avoided, and the bullet is ejected from a gap of the rotating blade. Specifically, when the blade of the aircraft propeller and the gun barrel of the airborne machine gun form a straight line, the airborne machine gun can automatically stop shooting, and then the blade can be prevented from being impacted by a bullet.

However, since visitors are typically ordinary persons, lacking in experience of actually operating an aircraft, knowledge of an aircraft shooting coordinator remains mainly at a theoretical level. And the traditional museum exhibits, the visitors see or hear video animation or theoretical explanation, and the action of the plane shooting coordinator is difficult to intuitively know and perceive.

Therefore, how to design a simple, feasible, convenient and easy-to-use airplane shooting coordinator principle demonstration device with visual demonstration effect has important significance.
