Embodiment Construction

[0023] refer to figure 1 , a secondary water rocket that utilizes air resistance to separate, consisting of a primary rocket body 6, a secondary rocket body 2, a secondary fairing 1 that is arranged on the secondary rocket body 2, a primary umbrella compartment 4, and a The separation control wing 17 at the bottom of the first-stage rocket body 6 and the separation controller 5 connecting the first-stage rocket body 6 and the second-stage rocket body 2 are composed of two pressure-resistant soda bottles. The connecting pipe 3 is connected, and the separation control wing 17 is a pair of labor-saving levers. The lever is connected with the hanging code 20 on the separation controller 5 through a steel wire rope 18, and one end of the separation control wing 17 is connected with the steel wire fixed on the first-stage arrow body 6. Circle 19 buckles, and rotates around it, is respectively provided with parachute in secondary fairing 1 and primary umbrella storehouse 4.

Abstract

The invention discloses a novel two-stage water rocket capable of being separated by air friction. The two-stage water rocket capable of being separated by the air friction comprises a one-stage rocket body, a two-stage rocket body, a parachute and a launch frame. The two-stage water rocket capable of being separated by the air friction is characterized in that the one-stage rocket body and the two-stage rocket body are connected through a separating controller, a separating control wing is arranged at the bottom of the one-stage rocket body, the separating control wing is fixedly connected with a hanging stack on the separating controller through a steer wire rope. A shackle switch, a barometer and a directional guide rail are arranged additionally on the launch frame. A manner of external force controlling trigger and separation is used, air friction which is impacted on the separating control wing in the accelerated rising process of a first stage water rocket is used skillfully for controlling the separation, and thrust of the one-stage rocket body is used fully, and an air pressure difference between the one-stage rocket body and the two-stage rocket body is small. Controllability and safety can be improved. The shackle switch is used for controlling the water rocket to launch, and a gas tube is prolonged. The barometer, the directional guide rail, the parachute and the like are installed. The controllability and the safety of the water rocket can be improved. The two-stage water rocket capable of being separated by the air friction is simple in structure, convenient to operate, safe, environment-friendly and stable in performance.

Description

technical field [0001] The invention relates to a water rocket, in particular to an external force control type two-stage water rocket which utilizes air resistance to control strong force with weak force. Background technique [0002] The water rocket is an environmentally friendly rocket simulator aircraft that uses common plastic bottles (such as Coke bottles) as materials, uses Newton's third law (action force and reaction force) as the principle, and uses air pressure and water as power. [0003] Water rocket launch is an extracurricular science and technology activity that simulates the rocket launch process. The activity process is exciting but also very safe. It is a comprehensive and practical science popularization activity that is entertaining, high-tech, and popular among young people. [0004] The existing two-stage water rocket utilizes separators between adjacent two-stage rocket bodies and internal water vapor releasing devices to carry out two-stage separati...
