Principles of the water rockets
       
      First we will look at the problem of propulsion. How does it all work,
      what is the thrust of a water rocket, what can be done to have a greater
      or lesser thrust, how to get a greater total impulse, all of these
      questions we will try to answer in the 
propulsion
        page.
      
      Then, it will be interesting to calculate the different parameters of the
      flight: altitude, range, peak time. This is what we will find in the page
      
"the flight"
      
      Finally, for the rocket to hold the performance that we will have
      calculated, its flight behavior will have to be as perfect as possible, in
      other words, for this rocket to be 
stable
      on its trajectory. We will therefore examine the factors that influence
      this stability and how to regulate them to have an optimal behavior. And
      to fully understand this part, the page on the basics of 
aerodynamics
      will provide some useful notions.
