The single seater EB29
Following the development of the EB28 and advancing it to the EB28 edition Binder Flugmotoren- & Flugzeugbau now presents the superlative single seater for the open class.
Based on the wing of the EB28 edition with a new designed fuselage which combines optimized aerodynamics with a maximum of comfort and safety for the pilot – the self-launching high performance EB29 will set a new benchmark.
First flight from Büchig Ostheim on 10.09.2009
- EB29
in a nutshell:
- low structural weight and high possible payload in the fuselage and as water ballast in the wings allows the utmost possible spread in wing loading
- optimized for best aerodynamics the edition-wing with new winglets makes higher cruise speeds as possible as superb slow speed capabilities
- variable wing span from 28.3 to 29.3 m, allows accomodation to various weather conditions by a simple change of the wingtips
- minimized drag due to the smaller wetted surface enables improved performance in comparison to the two-seater
- comfortable handling in flight and on the ground due to the electric gear retraction, the 2-diameter main bolts for better wing assembly, the large and sprung wheel, the generous cockpit with forward hinged canopy, the optimized and ergonomically placed systems for engine operation, flaps and control system
- type certification according to CS-22, the highest safety standard for glider construction

description
fuselage:
- body shell made of fibre reinforced plastic (CFK and aramide)
- extra spacious cockpit suitable also for tall pilots
- forward swinging canopy including one sliding window with integrated ventilation scoop
- instrument panel moves upward with the canopy
- TOST-safety release (for aero tow)
- total pressure probe in tip of the fuselage nosecone
- adapter in the fin to fit TEK probe
- static pressure probes (for air speed indicator and altimeter) on both sides of the tail boom
cockpit:
- removeable bucket seat
- safety belt
- seat cushion
- ram air entrance in the nosecone of the fuselage for ventilation and defogging of the canopy
- controllable ventilation on right side of the cockpit
controls:
- rudder control pedals adjustable during flight
- control rods made of CFK
- electrically adjustable trim with the operating switch on the control stick
- automatic elevator connection
landing gear and brake:
- rubber suspended, electrically operated retractable landing gear
- hydraulic disk brake
- tail wheel
power plant:
- power plant retractable into the fuselage
- solo engine 2625/2
- tooth belt driven reduction gear (1:3)
- water cooling
- double ignition
- electrical starter
- LiMg-batteries with 16,8 V max charching voltage for improved extension and retraction as well as starting of the engine
- engine control instrument fitted to the instrument panel
- Propeller Binder BM-G1-160-R-120-1
fuel tank:
- fuselage tank ~22 ltr
antenna:
- radio antenna in rudder
wing:
- 8-part wing with boundry layer control on the lower wing surface
- wingtip with winglets for wingspan 25,3 m, 28.3 m or 29.3 m
- built using high modulous (HM) carbon fibre
- aileron and flap gaps covered with mylartape
- double panel air brakes on the upper wing surface
water ballast:
- water ballast bags in the outer wings ca. 50 ltr capacity each
- water ballast bags in the inner wings ca. 45 ltr capacity each
- water ballast tank in the fin to allow for compensation of CG-movement using water ballast in the wings
finish
- white two component plyester coat or PU-coat
To minimize the structural weight the main parts of wing and fuselage are built using vacuum suction method. This allows the utmost possible spread in wing loading.
