Design and analysis of a new variable incidence wing and ruddervator mechanisms for UAVs

In scope of this study, a new special design of wing and ruddervator mechanisms are developed in order to take off and land UAVs from navy carriers with short runway. The angle of attack of wing of the UAV is gradually increased during take-off and landing in order to enhance the generated lift by wings. The design of these mechanisms are performed within "fail-safe design mentality" as these mechanism are Category-A class structures of UAVs. In order not to change the static stability of UAV while angle of attack of wing changes, it is mandatory to keep neutral point position unchanged, to ensure this, ruddervator angle of attack is also changed. It is aimed to shorten the take-off distance of aircraft by changing flight mechanics characteristics of UAV by dint of special mechanism design of wing and ruddervator.
