The strutless high wing created with attention to every detail. Elegant - fast - comfortable
The KR-030 Topaz is a strutless high wing.
All major airframe assemblies have a shell structure made of composites based on glass or carbon fibre. The fuselage in the form of a self-supporting shell stiffened locally with 3D material, houses a double cockpit in the front part with places next to each other.
Cockpit width 1.2 m. The shell is technologically divided into two symmetrical halves with stiffeners, and an integrated floor - trunk plate, glued in when connecting the halves.
Seats with a shell structure made of composites. Cockpit cover - a wind-up glass made of ultraviolet-resistant acrylic glass (PMMA polymethyl methacrylate), side door also made of acrylic glass (PMMA), 3 mm thick, on a composite frame.
Vertical stabilizer integral with the fuselage. Tricycle landing gear with a front wheel. The main landing gear legs self-supporting, made of composite. Main wheels braked together, front wheel controlled, coupled to the rudder. Optionally, the wheels are covered with laminated fairings.
The wing is made entirely, rectangular, mounted on four bolts. The NN-1817 profile was used for its resistance to contamination of the leading edge, with very favorable aerodynamic characteristics - tested on the PW - 5 "SMYK"glider. The wing structure is shell, sandwich, with a load-bearing girder.
Slotted flaps of shell construction, hung to the wing on outriggers, driven by the fuselage - electric, control on a joystick.
The aileron is made of carbon laminate due to the necessary high torsional stiffness, with the smallest possible mass (anti-flutter requirements) with a mass balance fixed at its end.
Classic horizontal tail with a rectangular contour, shell structure made of composites. Shell rudder. Pusher control systems.
Elevator trimmer - spring-loaded, electrically adjustable, control on the joystick
100 l fuel tanks mounted in the wings.
COCKPIT EQUIPMENT
The centrally located joystick gives a great freedom in taking up space in the cockpit. Additionally, during the flight, the pilot's hand can rest on the armrest, which is impossible in aircraft with a traditionally placed joystick or equipped with a yoke. Comfortable seats, profiled with adjustable backrest
CONTROL SYSTEMS
The control planes are powered by a system of rods and torsion tubes. Control of the elevator and ailerons via the central joystick located between the seats. Rudder control by two sets of pedals (in front of the left and right seat). Control of flaps and elevator trimmer, electric, by two sets of buttons on the joystick head. Control of main wheel brakes - with a lever on the joystick. Engine control (gas) - with levers on the sides in the aircraft cockpit.
DRIVE UNIT
Engine from the ROTAX 912 series. Fixed to the fuselage on a stainless steel tubing frame by rubber shock absorbers. Carbon composite engine covers, fastened with a Cam-lock quick coupler system.
AVIONICS
The plane is equipped with the Kanardia Nesis III cockpit glass as standard. It is a device that combines both EMS and PFD functions. It has a a touch screen with a diagonal of 8'4", which is perfectly legible even in sunlight. It has an integrated air navigation system with the ability to plan your own routes and upload previously planned sections.
It has many useful functions:
The standard equipment includes all necessary devices, such as Radio FUNKE ATR 833 Mk II, magnetic compass, inclinometer.
