A final year undergraduate project based on the conceptual design of a new twin-engine trainer aircraft named MKTS-7 has been carried out at the Hindusthan Institute of Technology. The new aircraft design performed is based on the idea to build a 4-seat high wing aircraft with two light engines (Rotax 912, usually used for ultralight aircrafts) and to enter the market with a twin-engine aircraft with the same weight of a single engine aircraft. The present paper shows all main criteria for the

The specification data are initially collected from the existing twin engine Italian aircraft, Tecnam P2006T. An aircraft aerodynamic investigation has been performed, especially to estimate the drag of the vehicle, both theoretically and experimentally (through wind-tunnel tests of a 1:100 scaled 3D printed model). Further, this paper focuses on the importance and application of the 3D printing technology and the ease of testing at the early stages of design. All tests and research activities are focused on the evaluation of aircraft geometric layout, aerodynamics and in particular on the estimation of the total drag value.
