Atec 321 Faeta

This advanced, aerodynamically controlled, double-seated cantilever low-winged aircraft with 3-wheeled fixed gear construction appears with its shape and design from legendary ATEC 122 ZEPHYR type. ATEC 321 FAETA retains its elegant aerodynamical design taking advantage of using the best carbon materials and carbon composites production methods applied on its construction. Although its design, performance and spacious cockpit give the feeling of higher weight category aircraft, in fact it joins the ultralight category thanks to high quality carbon technology, which guarantees excellent strength characteristics. Maintaining high safety factors, this plane complies even with the most strict weight limits and regulations.

Completely different wing structure is the main difference between Zephyr and Faeta. Carbon structure on Faeta´s wings helps to higher performances and different flight characteristics. New wing plan form and profile enable high cruising speed on low fuel consumption and easy manoeuvrability. Faeta´s high-performance flaps enable safety flight on extremely low speed, so the pilot can enjoy a landing. Higher volume of carbon composites and sandwich constructions using Nomex honeycomp helps Faeta to keep the low weight.

Actually, the latest modification is the tank replacement into wings as to provide higher safety to the crew. When maximum volume of 100l of fuel is filled up, the aircraft can reach amazing flight range of 1600km. Extremely fast and manoeuvrable aircraft provides high comfort of spacious heated cockpit, which gives safety feeling to the crew seating side by side.

New additional small windows on both sides of fuselage provide better view and open space feeling. Lightweight, but rigid construction allows the plane to be equipped with a modern rescue parachute system.

We pay attention to our client´s comfort and satisfaction, so we offer a large range of individual interior and exterior design modifications, optional equipment and individual custom dashboard instruments layout as it corresponds with client´s wishes, needs and user´s habits. Our intention is to let our client express his creative ideas applied on his own original design and configuration of his new machine. The cockpit is possible to adjust to pilot´s figure with adjustable seats and pedals.

Because of important advantage of low fuel consumption, our aircrafts can be effectively used not only for comfortable travelling, business trips, but actually also for towing gliders. ATEC planes are very popular in pilot schools due to their easy manoeuvrability and manipulation.

Technical description

The Wing

is a reinforced shell of a carbon-fibre sandwich. The tapered backswept wing of a SM 701 airfoil along the all span. The wing spar is made of laminated hard wood. The high efficient slotted flap has been developed using latest methods of computer design engineering. All external details of wing like flap hinges, slots, Pitot tube attachement, wing tips have been shaped with respect for minimum air drag.

The Fuselage

is a carbon-fibre shell braced by composite sandwich bulkheads of carbon, NOMEX honeycomp and hardened foam. The cross-section is elliptic with pure wing fillets and a spacious cabin. The hinged perspex canopy can swing upwards and backwards. 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 Tail Unit

all composite arranged in T-shape. The tapered horizontal tail surface with an elevator is constructed in a way similar to that of a wing. The tapered vertical tail surface is a monolithic part of the fuselage shell. The rudder suspended from the last fuselage bulkhead is completely 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. The main wheels are equipped with disc brakes. The size of main tyres: 350x120 mm, while that of front tyre is 300x100 mm. All wheels have aerodynamic fairing.

The Control

Dual control of all the rudders. The ailerons, flaps and elevator are controlled through the control rods and levers, the rudder through the steel wire ropes. All the control attachments are situated within the airframe. The important checking points in the 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 fix, ground adjustable or adjustable in flight. The engine mount is welded of the first-rate-quality CrMo steel tubes.

The Fuel System

consists of the fuel tank integrated in the fuselage and the piping connection equipped with a sediment bowl and a drain plug. The pressure of the fuel is measured by a fuel-pressure gauge.

Instrumentation

consists of basic flight, engine and navigation checking instruments. The static and dynamic pressure is taken from the Pitot tube attached below the port wing.
