Irbis LSA Basic model
Description
Aircraft for category LSA
Aircraft designed for tourism, operation in flight schools and rentals. The main criteria in the aircraft’s desing were the comfort of the crew, easy control of the aircraft, high safety and quality craftmanship. With an extra width of 1.25 m and a natural seating position, the cockpit provides comfort even during long flights. All controls are ergonomically designed and easily accessible from both seats, requiring minimal attention during operation.
The excellent landing gear allows operation from less quality surfaces. With engine Rotax 912 ULS (100Hp), the aircraft can be operated on shorter airports. Due to its excellent flight characteristics, it is also suitable for aviation training. The aircraft is ready for the installation of a towing device for glider towing.
Construction
The aircraft’s structure is all-metal. The highest quality materials are used such as aircraft alloy 6061 or steel ASI 4130. The entire control system is equipped with ball bearings.
The fuselage, wings and tail surfaces are half-shell construction. The wing is equipped with a flap and an aileron.
The lang gear is in a tailwheel configuration.
The steering is of the yoke type or controlled by a "stick" control, which, however, compromises comfort during boarding.
Comfort in the aircraft is ensured by a spacious cabin with a width of 1.25 meters, adjustable seats with the option of electric adjustment and sophisticated layout of all controls, tested on our previous projects.
The reliable Rotax 912 engine, equipped with a rocket rescue system, ensures a high level of reliability and safety for the aircraft.
The aircraft Irbis has fuel tanks of 80 liters located in the wings.
