E-PROPS GLORIEUSE : Range of In-Flight Variable Pitch Propellers for ROTAX serie 9xx
TECHNICAL DATA
✗ 3-blade tractor propellers, in-flight variable pitch system (Constant Speed), the lighest on the market
✗ For Rotax 912, 912S, 912ULS, 912iS, 914 & 915iS engines (for Rotax 916, under development)
✗ Hydraulic actuator with electronic management: the robustness of the hydraulic actuator and the precision of the electronics
✗ For all Rotax: configuration 2 (electric and fixed pitch) and configuration 3 (hydraulic). Except for Rotax 915iS configuration 2
✗ Ultra-fast regulation: max pitch / min pitch in less than 3 seconds, without jerks or speed variations
✗ Constant Speed or Single Lever (for 912iS and 915iS)
✗ Safety stops min. pitch / max. pitch
✗ Pitch variation: max. range 16° (20° in option)
✗ Available in 8 different diameters: from 155 to 190 cm
✗ For gear-drive engines up to 157 hp
✗ Max RPM at propeller = 2.600
✗ Moment of inertia : 2.600 kg.cm² (for the 170 cm diameter)
✗ Total weight: 3-blade propeller + governor + regulator + spinner = only 4 kg
✗ Very strong : 100% carbon, very high fibers ratio, RTM Manufacturing
✗ Carbon propellers with Titanium leading edge
✗ Compliant with ASTM F2506-13. EASA CS-P coming soon.
✗ TBO = 2000 hrs

GLORIEUSE range: the lightest Constant Speed propellers in the world
GLORIEUSE and reliability:
✗ no cyclic loading on aluminium components = no cracks
✗ no bearing = no jamming
✗ no lubricant = no leakage

The design of the GLORIEUSE variable pitch propeller blade is very aesthetic, and above all it reduces the pitch control efforts. This allowed E-Props to realize a low pressure hydraulic control (2 bars), thus to lighten the whole control system, with a small cylinder (diameter 50 mm).
PRICES:
Compatible accessories:
- E-PROPS SPACERS : 38 lengths of ultra-light spacers available, from -20 mm to + 170 mm
- E-PROPS SPINNERS : 13 diameters available, from 230 mm to 380 mm.
Glorisue on Blackwing 915iS: 413 km/h !
GLORIEUSE : the best performance on Rotax engines, by far.
How is this possible ? Thanks to the characteristics of carbon fibers, to the efficient RTM manufacturing process and of course the extensive calculations and tests of Jérémie Buiatti (designer of the E-Props propellers). 5 years and 4 successive versions of Glorieuse, to achieve an outstanding range of Constant Speed propellers.
Glorieuse is flying on the following aircraft and engines to date :
... Glorieuse is currently being assembled and tested on many other aircraft (soon here)
