Bell Helicopter's Hybrid Tandem Rotor (HTR) concept

[straighttailpilot]

trying to steal some ideas off of  Sikorsky??? haha.

[wellerocks]

man that's one bad idea.

[frankensteinmoneymac]

so....its not a tilt rotor, where the rotor tilts approx 95 degrees, for horizontal and vertical flight.....instead its a "HYBRID TANDEM" rotor.....which means it tilts only 25 degrees......

allrighty then....so....WHY is 25 degrees preferable to 95?!?! seriously just kind of wondering what the concept is here.

@frankensteinmoneymac

I believe they are more concern about how many seconds lost for transformation from heli mode to plane mode. With only 25 degrees angle this aircraft could evade groundfire much faster compared to the original osprey.

[frankensteinmoneymac]

@deestilo OK, well that makes sense I guess....but doesn't that just sort of beg the question of why an Osprey couldn't just tilt its rotors 25 degrees instead of 95 in such a situation as this? Even if its not set up to do that, it would seem a pretty minor modification to make the motor that moves the rotors do this.

@frankensteinmoneymac One possibility is the speed of transition from VTOL to forward flight. Another is structural: it's probably much easier to make tilt-wing system with less than 30 degrees of tilt, compared to 90+ degrees, due to the mechanical stresses and tolerances. Finally, efficiency. This system doesn't have to tilt its rotors to make them work for VTOL, but you have to tilt a wing's AOA over 10 degrees to get high lift, high-drag effects.

unstead of tilting rotars, it has an independant swashplate system for eatch blade, right?

[shaftster2001]

Now this is almost a direct copy of a soviet concept.

Ha!

So this is where James Cameron stole his Avatar helicopter idea from.

@3A7C not exacly, it come more from a real Osprey. Check this out;)

@3A7C

Halo!

[choralbird]

Note the jet nozzles on the wings. And the tiltWING design. It's neither a tiltwing nor tiltrotor; the rotor seems to be able to tilt independently from the wing. Add in possibly tiltjet and you have two sources of lift and thrust, plus torque control. If it works it would have some amazing manoeuverability.

[peepeevagi]

What's wrong with the Osprey now? It's an utter flying death trap, yeah, but will a fancy schmancy cabin and less powerfull engines fix it?

[MrDrumpy]

Have you also take some shots of the AH-6S Phoenix mockup at the convention?

[Cozzi0]

we alerdy have similar tiltrotors take the MV-22 opsprey for example and btw tilrotors arent that effective they use older outdadted tecnology and they are unpredictable sometimes

[BTR74]

You're both wrong...

NH90 FTW!! :D haha

Cool helo concept, tooo bad it won't likely leave the drawing board...the coolest ones never do

sikorsky "uh 60 black hawk" is the best helicopter in the world ! ...is the only ...is the king !

[odst121]

BAH! LIES

Iroquois "UH-1 huey" is the best helicopter in the world ! ...is the only ...is the king !
