1.4 Descriptive data

The "Arcus M" is a two-seat, high-performance powered sailplane, constructed from

fiber reinforced plastic (FRP), featuring camber-changing flaps and a T-tail (with

fixed horizontal stabilizer and elevator).

Wing

The four piece wing including winglets has 4 distinct trapezoidal sections.

On the innermost section of each wing, the leading edge sweeps slightly forward,

then from the second section on, the wing tapers more and more aft. The flaps

span evenly along the entire length of the wing and simultaneously serve as

ailerons. The ‘Schempp-Hirth’ style airbrakes have 3 panels and rise from the

upper wing surface.

The water tanks are integrated in the wing and can hold approx. 185 Litres

(48.9 US Gal., 40.7 IMP Gal.).

The wing skin is a CFRP foam sandwich, the wing spar caps are made from carbon

fibre rovings and the spar shear web is a GFRP foam sandwich.

Fuselage

The cockpit is comfortable and features two tandem seats. The one-piece canopy

hinges sideways and opens to the right. For high energy absorption the cockpit

region is constructed as an aramid/carbon fibre laminate, which is reinforced by a

steel tube transverse frame and a double skin on the sides with integrated canopy

coaming frame and seat pan mounting flanges. The aft fuselage section is a pure

carbon fibre (non-sandwich) shell of high strength, stiffened by CFRP-sandwich

bulkheads and webs. The main wheel is retractable with shock absorber struts and

features a hydraulic disc brake. The nose wheel (if installed) and tail wheel (or skid)

are fixed.

Horizontal tailplane

The horizontal tailplane consists of a fixed stabilizer with elevator.

The stabilizer is a GFRP/foam-sandwich construction with CFRP-reinforcements,

the elevator halves are a pure CFRP/GFRP shell.

The spring trim is gradually adjustable by a lever resting against a threaded rod.

Vertical tail

The fin and rudder are constructed as a GFRP/foam-sandwich.

Optionally a water ballast trim tank with a capacity of 11 Litres (2.9 US Gal.,

2.4 IMP Gal.) is provided in the fin.

Controls

All controls are automatically hooked up when the Arcus M is rigged.

SCHEMPP-HIRTH FLUGZEUGBAU GmbH., KIRCHHEIM/TECK

Arcus M FLIGHT MANUAL

Power plant

The „Arcus M“ was developed from the non-self-launching powered sailplane

model “Arcus T” by integrating a more powerful engine and a larger propeller.

The “Arcus M” is powered by an liquid-cooled 50 kW (68 HP) SOLO engine

- type 2625-02i - having a programmable fuel injection.

The power plant is housed in the fuselage aft of the wing, and an electrical spindle

drive pivots it such that the propeller pylon extends from the engine bay.

To stop the power plant, turn off the ignition and reduce the airspeed. After turning

off the ignition, the retraction process is conducted automatically by the engine

control unit MCU II.

With the engine control unit MCU II apart from the ignition switch, the RPM

indicator, the fuel valve and the throttle control no more controls have to be

considered. The fuel level in the control unit is displayed in LITERS.

In its appearance the “Arcus M” differs from the model “Arcus T” only by having

longer doors covering the engine compartment.

Flight characteristics and performances are identical with those of a correspon-

dingly loaded “Arcus T” (by means of water ballast).
