All moving tail plate interaction on an aerodynamic characteristic of the rocket plane in tailless configuration

The paper presents results of a numerical investigation for a rocket plane which is designed to suborbital space tourism flights. The vehicle is designed in a tailless configuration. The main goal of the research was to find an influence of the all moving tail (AMT)on rocket plane’s dynamic stability. The investigation was done for low and high angles of attack and subsonic speed. Moreover analysis was carried out for altitude equal 15 kilometres. CFD calculations were conducted by Panukl and MGAERO software. The dynamic stability analysis was performed by SDSA package. The analysis included evaluation motion mode as: Dutch roll, short period, roll, spiral and roll-spiral according to MIL regulation. The configuration of the rocket plane which fulfilled all required conditions of the dynamic stability criterion defined by MIL was obtained.
