AT -6

The AT-6 is an aircraft designed by Tomasz Antoniewski as a Three Surfaces Aircraft (TSA) unconventional configuration. AT-6 was designed as part of the project UDA-POIG.01.04.00-14-260/11-00 named: "Development of assumptions and creation of a new generation TSA hybrid airplane prototype". The company AT-P Aviation Sp. z o.o. commissioned the Warsaw University of Technology to analyse the stability of the designed aircraft. As a result of the analyses, the configuration was changed (Fig. 1) in order to improve the lateral characteristics of the aircraft, in particular Dutch roll characteristics (Fig. 2).
