Aerodynamic brakes are also cable controlled, in combination with springs. to establish a detailed database that allows the evaluation of numerical techniques. Ailerons and elevator are operated via rods, equipped with swiveling joint ends. helicopter is that the change in relative angle. The instrument panel of the plane is equipped with the following instruments: airspeed indicator, combined electronic altimeter/variometer, compass and bank indicator. Horizontal tail surfaces have similar construction as the wing and use modified Wortmann FX-71-L-150/30 airfoil.Ĭontrols and instrumentation. The brake is operated via a cycle brake lever, mounted on the control stick. The main wheel is fitted with a disk brake. Adjustable pilot’s seat is equipped with 4-point safety belts.įixed undercarriage consists of the main unsprung wheel (outer radius 400mm) and uncontrollable tail wheel (outer radius 140mm). The cockpit is ventilated via ventilation outlets, located on the instrument panel. The cockpit is equipped with aerodynamic brakes lever (left side), rope release control ("T" shaped handle on the instrument panel) and trim handle. In Heliciel, performance of calculated or measured profiles are stored as database containing the CL (lift coefficient), Cd (drag coefficient), Cm (moment. There is a ventilation window on the side of the canopy. Ribs are utilized as wings, struts, undercarriage wheel and rescue system mountings.Ĭockpit (closed type) is covered by a one-piece canopy made from a splinter-proof polycarbonate (Makrolon). Wing is fixed to the fuselage by mountings located on the wing beam and on the trailing edge section.įuselage, including the tail fin, is formed from a fiberglass monocoque. Wooden construction ailerons are also covered by a polyester fabric. On the upper part of the wing are located hinged aerodynamic brakes. Creation of a civil helicopter, airfoil and turboshaft database with technical and economical information in order to facilitate the preliminary design stage using a. Polyester fabric covers trailing part of the wing. Leading edge of the wing is covered by plywood and forms a torsion box. Front part of the ribs is made from expanded polystyrene. Integration with Airfoil Investigation Database Over 1500 different real-life airfoils with data included Interpolation of additional. Basic element of the construction is a plywood, box section beam and ribs made from spruce scantlings. Wing is based on the SM701 airfoil, trapezoidal outer part is modified into FX-60-126.
