Two-seat Multipurpose Light Aircraft Sigma-4
Russian >>
the town of Zhukovsky, Russia
Description
Center engine mounted on high wing ensures good viewing capabilities and convenient cockpit entrance, minimum variation of center of gravity position with different loads, decreases probable propeller damage during landings/ takes-off onto/ from unpaved aerodromes, especially with ski- equipped or float-type landing gear. It also shortens take-off run (Aircraft Performance) due to the good air flow around the flaps.
The modular design of the plane ensures easy change of the plane modification according to customer’s wish.
The main frame of the plane is made of metal; the outer skin of the cockpit and wing is made of three-layer fiber-glass plastic.
The basic version of the plane is equipped with a two-seat cockpit, whose large-area wind screen ensures almost all-round surveillance. The cockpit width is 1.22 m, the crew members sit side by side. The control is dual. The pedals can be adjusted to the pilot’s height. The luggage compartment, which is behind the seat backs, can hold up to 80 kilos of cargo. The seat backs are removable and foldable, which enables to place a long-measuring cargo (up to 2,5 m) in the cockpit. The spring-type landing gear (with the steerable front wheel) is equipped with the main wheel brake.
The plane can be completed with a fast-acting plane-and-crew parachute rescuing system and other additional equipment to the customer’s choice. With the wing and horizontal tail detached the plane can be towed by a passenger car. The assembly time after such towing is 15 minutes.
The simplicity of design, good thrust-to-weight ratio and controllability will leave you with a pleasant impression of the plane.
The plane is designed in compliance with European standards JAR VLA.
