The article discusses the initial study of the two-seat jet trainer with high manoeuvrability. The study included the concept of structural layout of the aircraft, as well as the development of its aerodynamics. The mail aim was to ensure the correct airplane characteristics (in particular control efficiency and dynamic properties) in the wide range of angles of attack. Another challenge was to ensure adequate aerodynamic characteristics at high transonic speed range. The geometry of the aircraft has been developed using CAD system (Simens NX). Initial aerodynamic study and aerodynamic design of the plane were performed using both: the low speed wind tunnel tests performed at Warsaw University of Technology using six-component internal balance and computational work performed using ANSYS CFX computer system. The first was used mainly to check characteristics at high angles of attack. Modifications of the wind tunnel model geometry at this stage were performed using the plastic mass (plasticine), or replacing some components of the model. An important problem with such approach was the lack of a precise definition of the revised geometry in the CAD system. Computational study was performed mainly to check high-speed characteristics. The final geometry of the modified wind tunnel model generally meets the requirements.
