THE ADVANCED ULTRALIGHT: HIGH WING AND RETRACTABLE GEAR

The incomparable flying qualities of the high wing configuration and the low drag benefits of the retractable gear. Weight, Power and Costs at Ultralight rate with an aerodynamic efficiency and performances better than general aviation aeroplane. Speed, Range and Comfort running toward luxury level. Compliance with airworthiness requirements, BFU, JAR-VLA, RAI-VEL. Metallic main structure with anticorrosive surface treatments. Engine Rotax 912 S 100 hp. The wingspan is about one meter shorter than the P92-S aircraft for improving its turbulence behaviour due to its faster typical speeds. The increased wing load, affecting the flap down speed requirement, is balanced by an improved bottom hinged slot-flap system which results in an almost Fowler flap efficiency retaining a very simple actuation mechanism. The fuselage of the P92 2000 RG has been completely redesigned, still maintaining the slender fairing between cabin and vertical fin. The internal cabin is now 4 cm larger than the previous aircraft (the internal max width is 120 cm) with rounded bottom fuselage allowing the necessary room for housing the main landing gear and improving the aerodynamics of fuselage itself. Like the previous aircraft, a steel truss structure is used for the cabin (high resistance for crash-landing emergencies) and light aluminium alloy for the tail cone.

The main landing gear is made by two supporting beams hinged around the end of two composite leaf springs housed inside the fuselage. This arrangement still allows, in a retractable gear, the use of the spring leaf for the landing shock absorption, preserving therefore all this advantage (simplicity, reliability, and maintainability). The main legs are simply rotated by two pneumatic actuators. The front wheel is integrated with a high efficient oleo-pneumatic shock absorber. The steering and the braking system are unchanged. When the landing gear is down the torque-arms are mechanically blocked, preventing the rotation unless driven by the actuators. An electrical compressor gives the necessary pressure to the pneumatic system headed up by two spherical tanks. One tank gives the necessary compressed air in case of system failure. In any case the gravity assures the extension of the landing gear . The panel indicators (up-and-locked, down-and-locked) comply with FAR requirement The instrument panel, wider than the P92-S, allows the most complete set of instruments and radio communication and navigation systems. The right side of the instrument panel has been rotated a few degrees to facilitate its reading from the pilot's seat
