of focus is put on the “elderly nature” of certain types of
aircraft in the various fleets in branches of the U.S. armed forces.
The Air Force has been working for years to get a replacement for the
aging fleet of tanker
aircraft and is hard at work on the F-35 program despite
continued setbacks.While the Air Force is getting its
replacement aircraft, some other branches of the armed forces like
the Army are not as well funded and are not seeing their fleets of
aging aircraft being replaced with new designs. Specifically the
fleet of helicopters in the Army's fleet need to be addressed, and
replacements need to be designed according to the
that while the Army is buying new rotorcraft such as the Apache and
the Blackhawk helicopters, those designs are from the 1970's. Modern
conflicts in Afghanistan and other countries have highlighted the
shortcomings of these aircraft have highlighted the need for modern
replacements. The Army has tried to replace its Apache attack
helicopter previously with the Comanche,
but the project was cancelled.The Army is now working with
other branches of the U.S. military to develop
a Joint Multi-Role (JMR) technology demonstrator aircraft modeled
on the Joint Advanced Strike Technology program that ultimately led
to the design and development of the F-35. The industry is excited by
the proposal of a new rotorcraft design, but worries that the program
may be underfunded as other programs to replace aging helicopters
have been. The aviation industry has formed a consortium called the
Vertical Lift Consortium that brings together large and small
companies with academia to help jointly design future
rotorcraft.Ned Chase from Amrdec said, "We’re funded
to build two clean-sheet aircraft that may or may not be the same
configuration."The Army is counting on its own funding
for the program and is counting on other research agencies like DARPA
and NASA bringing funding to the program as well. Amrdec director of
aviation Jim Snider said, "We plan to build two demonstrators,
but we’d like to have enough money to build three."Ultimately,
the aircraft design that the JMR comes up with would have to be
scalable in size and performance to replace all of the Army
helicopters that serve various mission roles like scouting, attack,
utility, and cargo and be appropriate for other branches of the
military that use helicopters as well. The rotorcraft designs would
have to scale as small as the OH-58D Kiowa Warrior armed scout and as
large as a replacement for the CH-47 Chinook helicopter. Performance
targets for the program include a speed of at least 170 knots and an
unrefueled operational radius of 294 miles at 6,000 feet in 95F
hot-and-high conditions. The aircraft would need to be able to loiter
on station for 30 minutes in cargo and utility configurations and up
to 120 minutes in attack and reconnaissance roles.So far,
initial studies have been finished and second phase configurations
analysis has started. The solicitation of industry trade studies were
to begin in fiscal 2011, but were delayed. The plan calls for
configuration studies in 2011 to 2013 with a flight demonstrator
around 2020 followed by a 5-year development plan leading to the new
helicopter entering service in 2026.

quote: Tail rotor (and assembly) getting hit was the largest source of helicopter loss for ARMY in Vietnam.
quote: LOL- the Marines haven't been the "first" to do anything since they landed in Somalia, and reporters were already there to film them. Vietnam: Army 1st Cav, Grenada: Army Rangers, Panama: Army Rangers, 82nd Airborne, and some SEALs, Gulf War: Army 101st Airborne, Afghanistan: Army Rangers, Iraq: Army & Marines, but Army pushed into Baghdad first. Semper Fi = late to the party. You'd get there faster if you took an aircraft instead of a boat.
quote: ou know, I know its a tad unrealistic - but I'd like to see new rotary aircraft based loosely on the vehicles seen in Avatar.That is, vectorable rotary lift engines in nacelle's. That, combined with some technologies found in the air-vectored pitch/attitude controls found on NOTAR concept rotary aircraft as well as in Harrier designs.
quote: The Avatar rotary-wing aircraft designs were absurd.
quote: Yes, because insanely complex, high-stress mechanical joints and a larger one-hit-kill target volume are fantastic ideas for low-altitude, low-speed combat aircraft.
quote: There you are in America, looking at future helicopter designs, whilst in the UK we can't even agree that we need them
quote: NASA bringing funding to the program as well
quote: Aeronautics research has been shortchanged by NASA for years.
quote: NASA did not provide that much support to the 787 program (how much money/research did they pony up, compared to the total development cost of that program?). The R&D cost of that one program is several times NASA's entire aeronautics budget.
quote: You should learn a little more about the state of the A&D industry before you go making simplistic, and inaccurate, statements
quote: Sorry WHAT!?!?Where do you think a lot of the grant money and research programs to build the knowledgebase used on the 787 airframe and engines came from?
quote: 1. Other companies involved in space exploration will not be so willing to fund joint research efforts as the corresponding monetary returns are much less than commercial aerospace.
quote: 2. NASA only provide for fundamental research in aeronautics; whereas they have to design, build, fly and maintain space vehicles.
quote: In general, most of space exploration is not a commercial enterprise, much as aeronautical research is not a commercial enterprise (which you yourself admit). So by your own argument, space research at NASA and aeronautical research at NASA are similar.
