Design and Construction 2.1 Airframe 2.1.1 Wings The wings are designed with a NACA 23012 airfoil with slotflaps. The shell structure of the wing is made in GFRP/PU foam sandwich construction with CFRP reinforcements. Every 30 cm foam rips are installed. The top flange and the bottom flange of the mainspar are made in CFRP. The spar web is a sandwich structure with GFRP/PU. The wing attachement is built with two mainbolts. The cross wing forces are taken by two theareted bolts. The aileron control as well as the flap control are automatically connected. .1.2 Fuselage and Cockpit The shell structure of the fuselage is made by GFRP/PU foam sandwich construction with CFRP reinforcements. The fuselage bulkheads are build in GFRP /PU foam sandwich construction with GFRP reinforcements, The fuselage supplies an integral fuel tank. The tank is built out of a GFRP/PU foam sandwich construction and treated inside with chemical resistant resin. The canopy is made in one piece and slides backwards by opening. 2.1.3 Control surfaces The structure of the stabilizer, elevator and rudder is made of GFRP/PU foam sandwich construction with CFPR reinforcements. The spar of the elevator is an aluminium tube. 2.2 Gear The D4 FASCINATION is equipped with a direct steering nosegear. 2.2.1 Main-and Nosegear The gear of the D4 FASCINATION is retractable and driven by an electric motor. In case of an electric failure it would be released by an emergency handle and automatically downlocked. electric motor disconnection emergency unlock cable electric gear motor knee joint nosegear main gear lock emergency handle emergency lock cable push rod drive distributor unlock drive connection cable main gear locks main gear flight direction 2.2.2 Brake system control stick brake handle second whee hydraulic system brake disc steel brake cylinder 2.3 Control systems 2.3.1 Longitudial control and Lateral control Control stick 2.3.1 Longitudial control and Lateral control 2.3.3 Directional control 2.3.4 Flaps control 30° push rod right flap flight direction flap handle 0° release button 15° 2.3.5 Elevator trim trim handle connected to elevator control tube flat spring bowden cable flight direction connected to stick control tube 2.4 Power-plant 2.4.1 Engine and Auxiliary systems The D4 FASCINATION is powered by a Rotax 912 S four stroke engine. waterbox oilbox carborator fuel pump inflow hose cabin heating valve cabin heating hose watercooler engine buffles oil return stroke hose thermal protection sheet exhaust pipe battery airbox oilcooler electrical pitching propeller drive muffler 2.4.2 Propeller Available are two propeller systems: a Mühlbauer b Rospeller (see example below) flexible shaft scissors drive composite or crabon blades hub spinner bracket planetary geared motor push pull rod electrically or mechanically acuated crank 2.4.3 Fuel flow
