I'm trying to figure out how to fly a VTOL I saw on TV. I figured out how the controls work, and how it generates lift and thrust, but I need to have something to practice actually moving the controls in, that won't kill me if I screw up.
The A/C has 4 lift pods with vectorable lift and thrust, with simple vane controls to change the direction of the lift/thrust vector. The lift changes as a square proportion to the input power with horizontal thrust varying directly with input power. Also the vanes can change an additional 50% of the thrust into lift at any power setting, with the remaining 50% still effective as horizontal thrust in relation to the longitudinal axis of the A/C. How would I model this? The center of the pods is located about.75 meters from the centerline, with the front pods about 1 meter from the CG and the rear pods about 1.25 meters from the CG. Would I need some kind of polar moment about all 3 axis to account for inertia? What about aerodynamic damping? As the A/C rotates on the yaw axis the vertical tail will create a counter force to the rotation that would vary as the square of rotational velocity, as an example. Help! -- Opus My gas is up to $1.99 a burrito, and I'm only getting 20 miles to the burrito. _______________________________________________ Flightgear-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/flightgear-users
