Mantiss - variable Z thrust and lift

8,548 Synthex4060  7.1 years ago

Another experiment with exotic controls.

Like inverted gull wings but don't feel comfortable with wings to close to the ground ? Look no more, this is the plane you need. As engines are brought down for cruise flight, the wings are brought backwards to compensate (partly) for the pitch variation.
Wings up (VTOL to 0) will give you roll stability and pitch maneuverability, while wings down (VTOL back) will give you pitch stability and roll maneuverability.
-AG1 : extra lights
-AG8 : variable wing positioning

EDIT : I did further testing with a proper controler. New conclusions :
-1 The system as little advantage on take off since full thrust with high CoT offsets the CoL forward extra pitch up. On landing though, since you use little to no thrust, you can make use of it to do very low speed landings.
-2 You can cruise with the wings low, but make a very quick dive by pitching forward and lifting the wings at the wame time. Do the opposite to recover from the induced stall.
