In one of my previous post I have considered drag. But now I have finishedthe work on the lift force. So here it is.Computing the lift vector and lift force on a rocket wasn't so easy. Wingswill be easier within this regard. Well, I didn't found any lift data for arocket nor could I use the lift data from some wings straight. But from myknowledge about the behavior of the lifting force on some airfoils I havederived a lifting model for a rocket. It's sort of a full lifting model givinga lift coefficient over the entire sphere (any attitude of the rocket). Thisis way more advanced than general lift data for some airfoils, which are justtwo-dimensional in a given sense. That is to say, for an airfoil, using such2d data is meaningless if the airfoil yaws around itself or the airfoil istraveling lateral with its wingtip being the, well, leading edge. This won'twork. However, as long as the main air comes over the leading edge, one canuse many of the known lift data for airfoils. However, I wanted to make thelift force for a rocket fully three-dimensional. Since this will give me thosenice swirling patterns induced by the action of the lift- and drag forceworking in conjunction on the surface of a rocket while the rocket undergoessome strong changes in direction.The following two animations demonstrate the working of the lift force.What we can see here are two rockets both pitched at 1/1000 degrees at lift-off. The rocket on the left will experience both lift (green) and drag (red)applied at the center of pressure (blue), while the one to the right will onlyexperience drag. Upon reaching maximum height both rockets will start to fall.The rocket to the left turns over somewhat earlier because the lift force aswell as the drag force are pushing on the rocket. But this lift force ismissing on the rocket to the right, which turns over solely due to the dragforce. One can also see that the lift force essentially stabilizes the rocketaround its flight path faster than without it -- and without any interactionfrom the outside (flight control).This animation shows the same rockets but now pitched at 6 degrees. Onecan see that the rocket with lift and drag rotates into a better angle leadingto a longer distance of travel.
