DUC Hélices is moving to the USA with the implementation of its first subsidiary in North America. DUC Propellers USA is located on Sebring Airport in the center of the sunshine state Florida. The company provides sales office, maintenance and repair workshop and storage. January 25, 2019 the new facilities greeted more than 200 guests during the grand opening, with welcome cocktails, french wine, buffet dinner and live concert. A expert sales and technical team is mandated by DUC for commercial deployment of innovative and strong added value products. "Opening a subsidiary in the US is obviously strategic in this country which counts the most important community of pilots in the world. All specificities of this huge market push ourselves to be present on this territory." Vincent DUQUEINE, DUC Hélices and DUC Propellers CEO said. DUC Propellers USA is the first international subsidiary opened in January 2019, following the new factory installation in Villefranche-Tarare Airport end of 2016. Beyond these two facilities, DUC owns a strong international sales network, with key professional partners. This network covers more than 100 countries and 35 aircraft manufacturers. |

The French propeller manufacturer DUC Propellers has lifted the veil on their innovation last spring at the AERO 2018 show in Friedrichshafen, by presenting a prototype of rotor for multicopteres (VTOL, flying car,...). Now, the company announced that its innovative branch dedicated to the design and the realization of helicopter and multicopter rotor is running at full speed Very large investments have been required to finance 4 years of studies for the development of the blades, the production press and the series of qualification and validation tests (form control, mechanical analysis of tensile strength/flexion/torsion, vibration tests, tests of ageing fatigue,...). The DUC Propellers company now offers catalogs products: - Complete rotor for Multicopteres (composite blades and hub Rotor head) - Helicopter blades (up to 8 m diameter) - Full anti-torque rotor (RAC blades in composite and hub). The company also proposes to study the realization of blades or complete rotor at the request of the customer. Thanks to its know-how, the DUC propellers company is becoming a key player in the manufacture of rotor, ie rotary wing. |

1) A new Hydraulic Constant Speed In-Flight Adjustable prop! Amazing weight
2) Reflight of the Certified FLAIR-2 on 180hp towing aircraft!
3) Quick Ground Adjustable prop, 1 sec. to change the pitch!
4) Rotor blade for helicopter and multicopter: DUC is now ready to produce!
5) New 5-blade carbon fiber hub! Lot of new possibility on our range.
1) Tout d’abord la société a officialisé la remise en vol de son hélice 5-pale FLAIR-2 Certifiée suite au développement et à l'approbation d'un nouveau moyeu en aluminium. Aujourd’hui, l’enquête du BEA est enfin terminée. Les examens ont montré que la nature du matériau, sa microstructure et sa dureté ne présenteraient pas d’anomalie vis-à-vis de nos spécifications. Le scénario mis en avant par le BEA est une non-conformité d’usinage dans la zone de rétention de la pale, favorisant la concentration de contraintes dans cette zone fortement chargée mécaniquement. Ces contraintes anormalement élevées ont permis l’amorçage d’une fissure de fatigue et de ce fait la rupture du moyeu.
Bien que l'ancien moyeu soit conforme et validé par les différents tests et calculs, nous avons décidé de revoir la conception de celui-ci pour éviter tout risque futur de non-conformité. Cette mise à jour du design du moyeu aluminium a été étudiée en fonction de l'ancien moyeu, en améliorant le dimensionnement grâce à différentes études de calculs par éléments finis réalisées par nos ingénieurs. Nous avons redimensionné le moyeu pour avoir une meilleure répartition de charges et nous avons augmenté les épaisseurs afin de réduire les contraintes maximales présentes auparavant. Suite à ces modifications, nous avons pu constater dans nos calculs et au travers de nos différents essais que ce nouveau moyeu avait une contrainte maximale divisée par 4 désormais, soit un nouveau coefficient de sécurité de 8. Désormais, elle prend l'appellation FLAIR-2-R. Pour le prix, celle-ci reste au même prix que l’ancienne FLAIR-2 soit 5 463€ HT.
2) Suite au succès des performances en vol de l'hélice tripale SWIRLBLACK-3 à pas variable en vol, les ingénieurs de DUC Hélices ont fait évoluer le système de variation de pas pour maintenant proposer une commande hydraulique à l'aide d'un gouverneur Jihostroj. Pour rappel, un gouverneur hydraulique permet de gérer le pas de l'hélice pour avoir un Constant Speed (régime moteur constant) lors des évolutions en vol. Une des qualités de ce nouveau système est sa plus grande réactivité lors du changement de pas. Mais son atout principal est sa faible masse à comparer de la concurrence : l'hélice tripale SWIRBLACK-3 en version hydraulique est à 6.2 kg ! La concurrence est largement placée au double pour une application identique...
Les essais de validation ayant été mené en interne sur notre aéronef d'essai, ce nouveau système va rapidement être proposé à la vente. Ce système est alors compatible à ce jour pour tous les moteurs Rotax 912, 912S/iS, 914 de Type 3, incluant le nouveau Rotax 915iS. Le prix varie entre 5 990 € et 7 200€ selon le modèle de pale associé au système hydraulique.
3) Dans la famille des hélices à pas variable, nous avons le plaisir de présenter cette année en Europe la nouvelle version "M", permettant un changement manuel de l'angle de calage des pales au sol en un éclair ! Ce système permet au pilote de faire varier le pas au sol en moins d'une seconde entre 2 vols. Ainsi, selon le type de vol prévu, l'accent pourra être mis sur les performances au décollage pour un effet STOL garanti, ou une optimisation des performances en croisière pour traverser le pays.
Cette nouvelle version s'applique aussi bien aux hélices tractives avec l'hélice FLASHBLACK-M, la SWIRBLACK-3-M ainsi qu'en propulsif avec l'hélice FLASHBLACK-2-M. Les différents prix sont dans le flyer en pièce jointe.
4) La grande nouveauté attendue par les pilotes et fabricants d’hélicoptères a enfin abouti avec la mise en service d'un nouvelle presse de fabrication conçue par DUC pour le moulage de pales de rotors d'hélicoptères permettant un moulage de pale jusqu'à 4 mètres de longueur, soit pour atteindre des rotors de 8 mètres de diamètre. Un nouveau rotor tripale de diamètre 3 mètres dédié à un aéronef multi-rotor sera d'ailleurs présenté au cours du salon AERO. L'activité Rotor est en plein boom chez DUC Hélices qui devrait au cours de cette année faire voler son 1er rotor d'hélicoptère de plus de 7 mètres de diamètre, en plus du multi-rotor de 3 mètres de diamètre. Grâce à son savoir-faire, DUC est en train de devenir un acteur incontournable dans la réalisation de Rotor.
5) Pour finir, nous présenterons également un nouveau venu dans la famille des moyeux carbones DUC : le moyeu carbone FLASH 5-pale ! Ce nouveau moyeu est dédié aux applications non certifiés, tractive comme propulsive, pour des motorisations de 135 à 180cv. Les applications ciblent sont en particulier les aéronefs STOL (décollage très court) ou machines propulsives.
Le prix est fixé à 1650 € HT.
Des versions 5-pales à réglage rapide de pas au sol et à pas variable en vol sont aussi en cours de développement. |

Nearly 20 years after its first rotation, DUC Propellers Company goes off to new horizons.
After 3 years of working, DUC Propellers received July 7, 2016 the EASA Type Certification for the 3-blade FLASH-R and 5-blade FLAIR-2. The 3-blade FLASH-R propeller allows today to equip all certified aircraft under 1200kg (2645lbs) and 160hp maximum power. Conducted by Nogaro Aviation, the STC of the DR400 re-engined with a Rotax 912iS and equipped with the FLASH-R must be obtained in the coming weeks. As for the 5-blade FLAIR-2 propeller, it has been specially developed to reduce noise on 180hp towing aircraft. The production of these propeller is now imminent, related to the finalization of the STC on Tower DR400 180hp. Note that DUC Propellers is willing to carry out more STC (Modification of certified aircraft approved by EASA) to modernize the current aircraft fleet. 3-blade FLASH-R from 4399 € and 5-blade FLAIR-2 from 7571 € (prices without VAT).
2016 marking a turning point in the evolution of DUC Propellers, a relocation project was launched in April 2016 with the primary goal to move the company on Villefranche-Tarare aerodrome to be at the heart of its business. Needless to say, this move will allow DUC Propellers to expand its premises and modernize further. The transfer is scheduled for November this year and an inauguration will be completed by next spring.
