11. DESCRIPTION OF AIRPLANE AND SYSTEMS
11.1. INTRODUCTION
This section provides description and operation of the airplane and its systems. Some optional
equipment, primarily avionics, may not be described in this section. More detailed information on optional
systems and equipment are available in section 15 - Supplements.
11.2. AIRFRAME
The M-8 EAGLE aircraft is a strut high-wing monoplane of all-composite structure, with two seats side by side.
1. FUSELAGE
The fuselage is made of carbon composite. Bulkheads are bonded into integrally stiffened skin to receive
forces from the landing gear, rescue system, stabilizer, rudder, safety harnesses and wings. There are two
doors with a central-lock system mounted on flush hinges on the sides of fuselage, opening upwards.
2. WING
Sandwich-type single-spar wings are made of carbon-kevlar composite house two fuel tanks within
leading section. Wings are fitted with a slotted Fowler flaps. Wings have rectangular center section with
trapezoidal tips. MS 313 wing profile is used. Banking control by ailerons with differentiated deflection 12°
down and 17° up. With aileron deflection up, a nose rises from profile, providing favorable yawing
moment. The wing strut is made of aluminum raindrop profile.
3. HORIZONTAL TAIL UNIT
The trapezoidal horizontal tail unit consists of the stabilizer and elevator and it is fixed into the fuselage
bulkheads by pins and screws. Aerodynamically balanced elevator has electrically servo-actuated trim
tab. The elevator deflection is 19° up and 14° down.
4. VERTICAL TAIL UNIT
Trapezoidal swept vertical tail. The rudder deflection is approximately 25°.
11.3. CONTROL
Airplane control consists of ailerons, elevator and rudder. Rudder has dual cable control, ailerons are
connected in the wings by a system of rods and controlled through cables, elevator is rod-operated. Yoke
controls, rudder and nose landing gear are operated by pedals with top-mounted shafts, which greatly
improve the kinematics of controls. The flaps are driven by central actuator through a system of rods. The
actuator control is located on the center panel.
Airplane is equipped with coupled control enabling flight with two-member crew.
Pedals – pressing left pedal turns aircraft left both on the ground and in the air, and vice versa.
Hand controls – pulling the yoke backwards, towards the pilot, raises the nose of aircraft (the angle of
attack increases) and the aircraft climbs. Pushing the yoke forward dives the aircraft. Turning the yoke to
the left banks the aircraft to the left, turning the yoke to the right banks the aircraft to the right.
Engine throttle – pushing (or turning right) controller located on the middle-panel increases engine
output, and vice versa.
Brake control – moving lever backwards, in the opposite direction of taxiing, brakes the aircraft. The
parking brake is controlled by button on the panel between the seats.
