Technical details

The Wing

is a reinforced shell of a carbon-fibre sandwich. The tapered backswept wing of an angle of 5,5° with SM 701 airfoil along the all span. The wing spar is made of laminated hard wood saturated with synthetic resin. The high efficient slotted flaps have been developed using latest methods of computer design engineering. Flaps control can be mechanical or electrical. All construction details of wing like flap hinges, slots, Pitot tube attachement and wing tips have been shaped with respect to minimum air drag.

The Fuselage

is a carbon-fibre shell braced with composite sandwich bulkheads of carbon, NOMEX honeycomp and hardened foam. The engine which is in the front part of the fuselage is separated by the firewall, to which the engine mount and the steerable nosewheel are attached. The cross-section is elliptic with pure wing fillets and a spacious cabin.

The Tail Unit

is all composite T-shaped construction which consists of tapered horizontal tail with fix stabilizer and elevator. Elevator trim can be mechanical or electrical. The tapered vertical tail is a monolithic part of the fuselage shell. The rudder suspended to the last fuselage bulkhead is completely made of composites.

The Landing Gear

is a fixed three-wheeled construction with a steerable nose wheel. The main gear is constructed as a pair of leaf springs of composites. The front leg is made of composites and metal tubes suspended with rubber spring. The main wheels are equipped with hydraulic disc brakes. Electronic main wheels size is 350x120 mm, front wheel size is 300x100 mm. Aerodynamic fairings are installed on all wheels.

The Control

Dual control of all the rudders. The ailerons, flaps and elevator are controlled by control rods and levers, the rudder is controlled by steel wire ropes. All control attachments are situated as to not interfere with the airframe. The important checking points in wings are equipped with inspection holes with a perspex covering.

The Engine

of standard option is ROTAX 912 UL 80 HP or ROTAX 912 ULS 100 HP that drives a FITI three or two blade propeller which can be fix, ground adjustable or adjustable in flight. The engine mount is welded of the first-rate-quality CrMo thin-walled steel tubes.

The Fuel System

consists of 70 litres fuel tank integrated in the fuselage or double tanks inbuilt in wings with a fuel capacity of up to 100 litres (2 x max.50l). The piping connection is equipped with a sediment bowl and a drain plug. The fuel supply is assured by two independent circuits and pumps. The fuel pressure is monitored by fuel-pressure gauge.

Instrumentation

enables a wide range of alternative individual solutions as by wish of client. We can offer basic analog instrumentation same as the most sofisticated electronic systems for flight and engine run monitoring and navigation. The plane can be optionally equipped also with position recorder, automatic pilot, various types of radios, transponders, ELT transmitters etc...The static and dynamic pressure is taken from the Pitot tube installed on bottom part of the left wing.

Cabin and canopy

Cabin is equipped with effective air ventilation, optional heating and canopy demisting fans. The hinged perspex canopy can swing upwards and backwards. Electrical blocking system on canopy lock disables to start-up the engine if the canopy is not closed well. Mechanical blocking system prevents from canopy self-opening during the flight. The basic version of canopy is colourless, optionally tinted in different colours. Whole cockpit can be upholstered with various types of fabrics and colours. Seats are adjustable. Pedals are possible to adapt in 3 possitions to the measure of pilot.
