This project is based on the revolutionary, new aircraft engine, the Rotax 912S. This engine is specifically designed to incorporate the latest technologies developed by the automotive industry. The Rotax 912S is FAR 33 certified and is currently the only aircraft engine approved to utilize automotive fuel, giving it a significant edge over standard GA engines. Some of the benefits include: Reduced frontal area and better power-to-weight ratio, lower fuel consumption lower propeller rpm resulting in higher efficiency and lower acoustic profile, and stable cylinder head temperatures due to liquid cooling.
To date, this modern aircraft power plant has been used successfully in two-seat aircraft, its relatively low power capacity (rated at 73 kW/100 hp) making it a popular choice in the aviation industry. It has become increasingly evident, therefore, that a potential market exists for a fourseat aircraft powered by two of these Rotax engines, with very little weight disadvantage. The result is the P2006T. This twin-engine formula offers higher safety and lower operating costs than its single engine counterparts. Extensive research for this project has proven that the light twin-engine aircraft will have a lower standard empty weight than comparable single engine four-seat aircraft in the 180 hp or 200 hp class.
The Tecnam P2006T also offers better performance, greater cabin comfort and, due to its unique ability to use automotive fuel, much lower operating costs. For the sake of comparison, the Lycoming 0-360-A1A 180 hp weighs 146kg and has a frontal area of 0.4 m2, while the Rotax 912S (with the same accessories) weighs only 64 kg and has a reduced frontal area of just 0.15 m2. The Lycoming generates its maximum power of 2700 rpm at the propeller and the Rotax at 2400 rpm.
The Tecnam P2006T's empty weight is the lowest among its direct competitors, while the payload is higher. This can be attributed to the high structural and systems efficiency and because of the excellent weight-to-power ratio of the Rotax engine.
The wing-mounted engines relieve the aerodynamic load on the wing with a consequently lighter structure. The remarkable propulsive efficiency of the Tecnam P2006T is attributable to the low propeller rotating speed and the low engine drag. These, together with a streamlined fuselage, result in uncommonly efficient aerodynamics.
The Tecnam P2006T clearly boasts the highest ceiling and climb speed among its competitors. From an operating point of view, the following points are worth considering: The option to use automotive fuel as well as AVGAS allows Tecnam P2006T operators to dramatically reduce direct costs, making it possible to fly in regional or remote areas where AVGAS is difficult to find or prohibitively expensive. The dependable twin-engine configuration of the Tecnam P2006T allows it to be flown over long distances and in areas where ground facilities are poor.
