Dynamics model and simulation optimization analysis of single stage water rocket
The initial launch parameters of water rocket have a significant impact on its flight performance, such as speed and altitude. In this paper, the dynamic equation in the form of parameter increment was obtained through the force analysis of the ascending section of a single stage water rocket, which can effectively reduce the complexity of the numerical calculation program. The numerical calculation of water rocket flight speed, altitude and other parameters was carried out, and the optimization design direction of three parameters of nozzle diameter, initial water loading and initial pressure was proposed. The results indicate that reducing the nozzle diameter will increase the duration of the propulsion phase and affect the maximum speed and height that the rocket body can reach during the propulsion phase. There is an optimal volume ratio of 0.50 for water loading to achieve the highest flight altitude. As the initial pressure increases, the maximum flight altitude linearly increases with a pattern of 0.0767 m/kPa, while the duration of the propulsion phase will decrease with the increase of the initial pressure. The analysis in this paper provides an important reference for the scheme design and structural optimization of water rocket missions.

期刊介绍:
Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics.
Results in Physics welcomes three types of papers:
1. Full research papers
2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as:
- Data and/or a plot plus a description
- Description of a new method or instrumentation
- Negative results
- Concept or design study
3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
