Machine-Gun Synchronization Gear
★Exhibit Content: Popular science on the working principle of an aircraft machine gun synchronizer ★Interaction: Electromechanical interactive experience ★Operation: 1. Adjust the knob to control the propeller speed (0-1500rpm); 2. Press the trigger button to simulate machine gun firing; 3. Switch between "Deflector Plate Mode" and "Synchronizer Mode" to observe the difference in the probability of bullets hitting the propeller blades under the two schemes; 4. Observe the linkage between the propeller blades and the machine gun to intuitively understand how the synchronizer ensures that bullets are safely fired through the gaps between the blades. ★Exhibit Description: The exhibit consists of an enlarged Fokker E propeller, a machine gun model, a synchronizer mechanical transmission structure, a transparent protective cover, and an interactive control area. It is a recommended exhibit from the PopsciCat Exhibit Store. The exhibit uses a desktop integrated cabinet, with a high-strength transparent protective panel added on the outside, fully displaying the mechanical transmission mechanism in front of the audience. Visitors can freely adjust the rotation speed of the propeller through the panel knob, with an adjustment range of 0 to 1500rpm; pressing the trigger button triggers the simulated machine gun firing, using laser or LED light effects to simulate the bullet trajectory. The exhibit provides two working modes for comparative demonstration. In the deflector plate mode, there is no synchronization control, simulating the early aircraft scheme, and there is a risk of bullets hitting the propeller blades; in the synchronizer mode, it relies on a cam-linkage mechanism. When the propeller blade rotates to block the muzzle position, the machine gun stops firing, and only when the blade rotates to a gap position does the machine gun trigger firing. ★Scientific Principle: This exhibit restores the classic working principle of the aircraft machine gun synchronizer during World War I. Early propeller aircraft directly mounted machine guns on the nose. When bullets were fired, they could easily hit the high-speed rotating wooden propeller, causing blade damage, aircraft destruction, and seriously threatening the pilot's life. The firing synchronizer relies on a mechanical linkage mechanism composed of cams and connecting rods to transmit the rotation position signal of the propeller to the machine gun bolt, achieving precise synchronization of the firing timing. Only when the gap between the blades rotates in front of the muzzle

Only when the gap between the blades rotates in front of the muzzle is the machine gun allowed to fire bullets; when the blade body rotates in front of the muzzle, the firing mechanism is locked and will not fire.
