An experimental composite-construction aircraft, developed in 2011 by Edward Marganski, MSc Eng., to test a new control system known as the “Marganski winglet”.
This solution, patented in 2009, is a modification of the canard configuration (with the stabilizer placed ahead of the wing), eliminating its drawbacks while retaining its advantages. The winglet is freely suspended on an axis perpendicular to the aircraft’s plane of symmetry and equipped with flaps on the trailing edge, connected to the control stick.
Deflecting the flap generates a moment that deflects the entire control surface, as in the case of an elevator trim tab, but in a way that allows normal control. As a result, the angle of attack of the winglet is independent of the aircraft’s position relative to the incoming airflow, ensuring that balance and longitudinal controllability are maintained throughout the entire range of usable angles of attack of the main wing.
Malgosia II was first flown in Mielec by Jaroslaw Rozwod in May 2014. The initial flights were performed with conventional controls and a freely suspended front stabilizer, while subsequent flights used only the front stabilizer.
