J'avais commencé les infos sur le prototype RAIDER sur le fil petit nouveau http://www.air-defense.net/forum/topic/6395-ptit-nouveau-sur-le-marché/?p=799546, voire sur celui l'hybride ici http://www.air-defense.net/forum/topic/6312-hybride-dhelicopt%C3%A8re-et-davion/page-26#entry808755

Sikorsky S-97 Raider Specification & Technical Data

Posted by: Marvin Diaz October 4, 2014 0 0 Views

 
 

In mid-2008, Sikorsky unveiled a revolutionary technology demonstrator. They called it the X2. Just two years later, the very same aircraft was performing unbelievable maneuvers and had unofficially dethroned the Westland Lynx to become the world’s fastest rotorcraft.

 

The secret behind the X2’s speed and agility was the presence of a set of composite, four bladed, coaxial rotors. Though this area demanded a high level of expertise, Sikorsky had been working on this specific area for decades on different rotorcraft, starting with the X-69 followed by the UH-60 Black Hawk and the RAH-66 Comanche.

 

What the coaxial rotors meant was that a separate tail rotor was not required. This freed up some real estate on the tail for the addition of the pusher propeller. The pusher propeller produced a considerable amount of thrust and played a major role in increasing the top speed of the rotorcraft. A single LHTEC T800 LHT 801 turbo shaft engine powered both the coaxial rotor blades as well as the six bladed pusher propeller.

Sikorsky unveiled two S-97 prototypes at its facility in West Palm Beach, Florida on October 2nd. “Sikorsky will begin ground testing shortly and is on track for first flight this year,” Sikorsky’s Advanced Military Program Director Steve Engerbretson said. “The entire flight program will take about a year to complete.”

There is good reason for Sikorsky to finish flight-testing of the S-97 as soon as possible. The Stratford based company and its partners have privately funded the entire S-97 program. Therefore, they intend on offering the S-97 to the US Army as a replacement for the OH-58 Kiowa Warrior, a helicopter that dates back to the Vietnam War era, as part of the Armed Aerial Scout program (AAS).

 

The OH-58 Kiowa Warrior was primarily an observation or “scout” helicopter, also capable of fulfilling the light attack role. Due to its small size and ability to get in and out of sticky situations without so much as breaking a sweat, Special Forces operators preferred it. The S-97 Raider seems to be ideally suited for this role, as it not only lives up to, but also improves upon the characteristics of the OH-58 Kiowa Warrior.

 

With a top speed of almost 220 knots, heavy armament, high power to weight ratio and the ability to carry up to 6 personnel, the advantages of the S-97 are as clear as day. However, if the last couple of years have taught us anything, it is not to be over reliant on technology.

“If it’s not broken, don’t fix it”. It will be interesting to see if the S-97 Raider will be able to achieve what the V-22 and the F-35 as of yet, have not.

En complément du Tweet de Philippe ci-dessus, un autre article (de Defensa.com) faisant suite à l'annonce du début de tests au sol du S97 Raider, et surtout une autre ch'tite photo du bébé publiée par Sikorsky

Sikorsky termine l’assemblage du second « Raider » !

554744630.jpg

West Palm Beach, Floride, Sikorsky Aircraft Corp a annoncé le début de l'assemblage final du second prototype de l’hélicoptère S-97 « Raider » de développement.

 

 En collaboration avec ses fournisseurs de l'industrie, Sikorsky développe deux prototypes du « Raider » dans le but de démontrer les nouvelles capacités révolutionnaires en ce qui concerne la maniabilité et la vitesse de vol.  Le «Raider» est basé sur la technologie du X-2 développé par Sikorsky à la fin des années 2000. Le démonstrateur X-2 est une plate-forme de 5’000 livres, alors que le «Raider» est d'environ 11’000  livres et permettra d’emporter jusqu’à six soldats en mode assaut. En mode reconnaissance, cet espace pourrait être utilisé pour l'équipement supplémentaire ou des munitions avec 2 pilotes et réservoirs de carburant auxiliaire. Outre, sa vitesse maximale presque deux fois supérieure, à 250 nœuds, le S-97 sera plus manœuvrable et aura une signature acoustique plus faible qu’un hélicoptère standard.

Ce n'est pas que j'ai des actions chez Sikorsky, mais je trouve cette vidéo promotionnelle géniale et super bien faite : on y voit toute la gamme des appareils qui pourraient potentiellement être dérivés de la "X2 Technology", y compris à la fin des magnifiques drones rapides de reco/attaque !

Ce n'est pas sa vitesse maximale, c'est une étape dans ses tests 

Le X3 a pris 8 mois pour atteindre 232 noeuds.

Le S-97 a pris 3 ans et 4 mois (40 mois!) pour atteindre 200 noeuds.

Cherchez l'erreur...

Mais il est possible que le S-97 soit vendu à des forces armées.

Faux frère !  Tu donnes combien d'année au S-97 pour arriver dans les forces en question ?  Et puis nous, on est les meilleurs ! Voilà c'est dit !    C'est simple !   Allez on t'aime bien !
