Water Rocket Veering Off? Is it the Launcher, Operator or Laws of Physics?

This brief video touches on centrifugal force, inertia, water volume, and the effects these variables and laws of physics have on launching water rockets. There are numerous variables that need to be accounted for and controlled for optimum success. Water volume is a major player when it comes to water rocketry, but it can be a hinderance or a help depending on how it is implemented. The video covers 4 scenarios yielding varying results depending on water volume and other factors. Watch this video to take your water rocketry to the next level when you understand the affects that some laws of physics have on launching. Advance to the topic of interest via the menu below:

Keeping it pointing straight up and allowing the water to stop moving are petty effective. I encountered 'wobbly' flight when shooting at an angle as a wave starts up inside the rocket. You can predict the flight characteristics of a particular amount of water against such things as rocket weight, pressure and so on by using a water rocket computer model - online computer models will run in your web browser and you can either change the values of things like rocket mass, mass of water, pressure and so on manually or you can get the water rocket computer model to run itself automatically to optimise your chose value pairs (say rocket mass and water, optimised for maximum flight time).

Спасибо. Полет таких ракет зависит от объёма бутылки, количества воды, давления, и диаметра сопла. Мои ракеты объёмом 0.5 литра летают при стартовом давлении 10-12атмосфер намного лучше. Смотрите и учитесь.
