Parallel modular flexible power device for water rocket

Abstract

The invention relates to a parallel modular flexible power device for a water rocket. The parallel modular flexible power device comprises a nose cone part (1), an interstage part (2), an empennage part (3) and a power part (4), the nose cone part (1), the interstage part (2) and the empennage part (3) are coaxially and detachably connected in sequence; the power part (4) is detachably connected with the empennage part (3); at least one interstage part (2) is arranged; a parachute device (11) is arranged in the head cone part (1); and one or more power parts (4) are connected in parallel. The water rocket device is light in weight, sufficient in power, simple in structure, convenient to assemble and disassemble and high in reliability.

Description

technical field [0001] The invention relates to the technical field of model water rockets, in particular to a parallel modular flexible power device for water rockets. Background technique [0002] The production of water rocket is mainly divided into three parts: arrow body, nose cone and tail. The rocket body is the main part of the water rocket, mostly made of carbonated beverage bottles. The basic shape of the water rocket is maintained, and the interior is connected to form a cavity, which stores an appropriate amount of water and high-pressure gas as flight power. The nose cone is located at the front of the rocket body and acts as a fairing, which is mostly a conical rubber part to maintain the good aerodynamic shape of the water rocket. The tail is located at the tail of the arrow body and is mostly cut from cardboard or thin wood to maintain overall balance and stable posture. [0003] The working principle of the water rocket is as follows: the cavity of the ro...

AI Technical Summary

Problems solved by technology

If the arrow body is bent, it will be difficult to rise vertically during launch, causing problems such as trajectory deflection and low flight height; if the arrow body has gaps and poor airtightness, water will flow out or high-pressure gas will leak, resulting in insufficient power and flight. The altitude is low and the flight time is short; if the surface of the rocket body is not smooth and flat, it will be difficult to fix the nose cone and tail on the surface, resulting in uncoordinated overall structure, instability and loss of control

Moreover, the water rockets produced in this way have poor adaptability, single application scenarios and purposes, and the same structure and type of water rockets need to be repeatedly produced in various specifications to meet different needs.

Moreover, the rocket body made by connecting through the carbonated beverage bottle is easy to be damaged, and the number of repeated use is low, which greatly increases the time and labor cost of the handmade water rocket model.
