US Joint Heavy Lift

[donnage99]

I know that, but in Sweetman's article, he stated to have seen the concept in a video, so I just want to see it.

"If you have a sensation at this point that someone is using mind-altering chemicals, you are not alone"
ROTFL!!!! ;D

But quad-rotors are old hat, remember how successful X-19 was in the sixties already?

True but we should also remember that the X-22A was a very successful quad tilt rotor (albeit ducted rotors), that flew for many years.

Hi,


here is Boeing Advanced Tandem Rotor Helicopter (ATRH).

I think that is a nice artist's impression of the future devolped Chinook. I found it on Google Image

I don't remember if this picture for Boeing future helicopter and VTOL aircraft was
sent before or not .

 

[yasotay]

Those are from some of the initial work Boeing did for the JMR effort.

Hi,

the Sikorsky VDTR Model concept.

Karem Aircraft concept:

 

[Rickshaw]

Fin appears to be rather under-sized.

Fin appears to be rather under-sized.

Same with Boeing ATT concept. Early ATT design even eliminates both horizontal and vertical tails altogether

 

[yasotay]

I suspect they used differential rotor thrust for primary yaw control. Only reason I can think of for such a vestigial vertical stabilizer.

Hi,

I don't know if that was just a hypothetical concept or a basis for a real design ?.

Hi,

here is a Boeing SSTOL design.

Hesham, please read what is JHL before posting stuff in this topic
http://www.secretprojects.co.uk/forum/index.php/topic,2765.msg12865.html#msg12865

What http://sagita.be has to do with FVL/JHL??

 

[hesham]

Sorry my dear Flateric,I fixed it.

Once more, read what is JHL that started in 2005!!!

OK my dear Flateric,please transfer it into a proper topic.

Going through this thread I noticed no videos although one had been posted but with a broken link. Despite program cancellation, the desire for a heavy vertical lift capacity with theater sized range still exists. Unfortunately, it would take a self funded prototype to demonstrate actual benefits before any budget/political support could be generated (as a follow on extension to Future Vertical Lift perhaps).

[jsport]

I see the enemy is dropping his forces 30 km behind the battle line with a wing of giant tilt-rotors...

The idea is a HLZ 100s of Kms and after most of the SEAD/Time Critical tgting phase is over. Smerch is aTCT TEL.

This picture of the Boeing ATRH concept is featured in Popular Mechanics.

Edit: Picture not more available at Popular Mechanics.

Looks like Eurocopter FHTH then again Boeing was initially part of the partnership .

cheers

Boeing knowing the Army well, doubted that "winged things" would be popular with the senior aviation officers or the rest of the Army. Their logic was that this was a low risk option. With JHL there were no low risk options.

@jsport - Indeed the recognition that there was a significant number of artillery means that could respond rapidly led to the "air-mechanized force" becoming a less favored capability over the fantastic amount of logistics that these platforms could move forward. Indeed the ability to move materials from port to the fight in one trip was what kept the effort alive until USAF Inc., stepped in and said it was their mission. A mission they have only done in critical circumstance (Khe Sahn as an example), not as a regular endeavor.

In fairness to the USAF (not to be mistaken for USAF Inc., that resides in leather chairs in the Pentagon), putting high value aircraft like C-17 at risk in the forward area landing in the dirt really makes no sense. C-130 however certainly could do the mission, but are also a high demand, low density platforms. Because of this low density the USAF focuses on efficient aircraft operations. The Army finds effective to be more critical to their operations. Thus JHL, then C-27J, were developed to meet the Army's desire for effective logistics. My ire with USAF Inc., is, that even being told this, they (successfully) lobbied to have those programs turned over to the USAF, and then promptly cancelled both while keeping the (Army) funding for them.

NATO needs large helios..Many folks looking past each other like a GM Board room discussing airbags that dont work.

 

[TomcatViP]

The way Nato airlift capabilities were dwarfed by the USAF fractional usage of their tactical airlift force in Kabul might surely have been an electroshock to many. After all the lullabies from Airbus, the stark reality might have dug in a bit. I hope.
