Let's say we have an aircraft with a typical wing configuration that consists of primary wings at the center of the aircraft, a pair of horizontal stabilizers fitted with elevators at the tail and a vertical stabilizer with a rudder at the tail. In negative angle of attack, lift points down. In positive angle of attack, lift points up from the aircraft. When a wing's angle of attack changes, its lift changes. If anyone's interested, long-winded answer below:Īctually wait before i can say anything else, let's set some stuff straight firstĪn aircraft is kept flying and in motion by two main forces: thrust and liftĬontrol surfaces work by modifying the lift of the wing.Īll aircraft turn by increasing or decreasing their angle of attack (this is the difference between the aircraft's path of motion and its orientation). Sorry for making so many edits btw im still figuring this out myself. The turning will vary across aircraft, though for most conventional fixed-wing designs the effect won't be pronounced unless those additional vertical wings rival the size of the primary wings or you add engines or something. *Adding an inverted rudder on that wing helps with the turning. That way, when you yaw, the angle of attack for the vertical wings changes the lift to point in the opposite direction of the rudder's yaw, and allow you to turn. A simple, lightweight solution would simply be to add two a small vertical rudderless symmetrical wing near in front of the center of mass, one at the top and one at the bottom. I think yaw is represented pretty well in this game to be honestĮdit: oh dammit i'm dense i wrote a whole bunch of stuff without directly answering the main questionĪnyways OP, your aircraft isn't going to turn by yawing unless you add something else at a different point along the longitudinal axis *in front of the CoM of your aircraft to provide a force in the opposite direction of the force generated by your rudder.
