Counter-Flow Air Rocket Principle Demonstrator
★Exhibit Content: Principle demonstration of opposed air rocket ★Interaction: Electromechanical interaction ★Operation: Press the pressurizing lever up and down multiple times to pressurize the pressure vessel; observe the pressure gauge reading on the tabletop; when the set pressure value is reached, press the yellow launch button to launch the rocket model. ★Exhibit Description: The exhibit consists of a display stand, manual pressurizing lever, pressure gauge, pressure vessel, high-transparency acrylic protective tube, rocket model, high-pressure solenoid valve, and electrical control box. It is a recommended exhibit from the KexMall exhibit mall. Visitors manually repeatedly press the pressurizing lever to continuously inject air into the pressure vessel for energy storage, while observing the real-time pressure value changes on the pressure gauge; when the pressure reaches the preset threshold, press the launch button, and the compressed air inside the vessel is instantly released, generating a powerful thrust that propels the rocket model rapidly upward along the acrylic protective tube. Visitors can intuitively watch the complete dynamic process of rocket launch and immersively experience the mechanical phenomenon of rocket launch. It is suitable for primary and secondary schools and science museums to carry out mechanics-themed science education. The safety protection structure can prevent the rocket from ejecting and causing injury. ★Scientific Principle: This exhibit relies on Newton's third law, namely the law of action and reaction, to simulate the rocket propulsion principle. Compressed air is ejected backward, exerting an equal and opposite forward reaction force on the rocket model, which is the thrust for the rocket to lift off. Real rockets also rely on this principle in the vacuum environment of space, without the need for an air medium. The exhibit uses compressed air to simulate jet propulsion, helping visitors understand the physical laws of rocket lift-off and correcting the misconception that rockets rely on air to lift them.
