Karem Tiltrotor A Contender For Army Utility Role

Image

When the Pentagon set out its Future Vertical Lift (FVL) strategy to develop a family of advanced rotorcraft to replace its fleets of helicopters originally designed in the 1960s and '70s, one goal was to engage non-traditional suppliers to bring more innovation into the sector.

With the inclusion of two startup companies among the four teams awarded contracts for the U.S. Army's Joint Multi-Role technology demonstration (JMR TD), the Defense Department has taken a step toward that goal. Bell Helicopter and a Sikorsky/Boeing team may still be the favorites to fly two high-speed rotorcraft demonstrators in 2017, but they face real competition from two relative unknowns.

AVX Aircraft had already declared its hand, previously unveiling the 230-kt. coaxial-rotor, ducted-fan compound helicopter it is designing for JMR. But Karem Aircraft was not confirmed as a contender until Oct. 2, when the Army announced the four cost-sharing technology investment agreements for the $217 million JMR TD Phase 1 flight demonstration.

Karem Aircraft was formed in 2000 by Abe Karem, designer of the Predator unmanned aircraft and A160 Hummingbird unmanned helicopter, to develop his optimum-speed tiltrotor (OSTR) concept. Along with the other teams, Karem now has $6.5 million and nine months to complete preliminary design of its JMR demonstrator, the TR36TD, after which the Army will select two designs to be built and flown.

Interesting, but I wonder if countries will pay for the premium of VTOL (the article states FVL whatever the hell that is http://en.wikipedia.org/wiki/Future_Vertical_Lift ) when the other options (with the exception of the Grizzly) are cheaper STOL and helo alternatives.

I guess range the load and range is better than the helo's but surely C130's, V22's, and Chinooks can cover enough ground to not make the extra expenditure necessary.

One of the contenders for the FVL that I had never seen before now.

Piasecki X-49

Looks like they went down to Home Depot, bought an industrial size floor fan and bolted it on to the back of the helicopter!!

Interesting company website. Several helicopters I had never seen before mentioned in their history.

That thing (TR75) is going to need much larger rotors or they can go ahead and drop the V from it's capabilities. I'm guessing from the three view that they want it to be able to do a full running takeoff. Forget it. Just have it do one like heavy V-22s do with the prop-rotors at 40 degrees.

Honestly, I'm surprised that the Army hasn't gotten in on the V-22 now that it's combat proven.

Piasecki X-49 was a nice "hey look what we can do" prototype, but was completely impractical as a real aircraft. Look where the wings are. Go ahead, try to unass that in a hot LZ.

I suspect the V-280 has a lock on the light utility/ UH-60 replacement.

Frank Piasecki started the company that is now Boeing Helicopters. Lots of history there.

And as a former paratrooper I can tell you I would refuse to jump out of that thing at any speed with that big ass meat grinder whirling around back there!!!! {bugeye}
