Little confused there brat


No doubt my underlying desire for Boeing to be successful, LOL, in any regard while I like the Osprey, I think the single mast contra rotating Bell Defiant is an amazing machine, that is technologically and operationally less risky, but hey, what do I know?? LOL

Bell V-280 Valor reaches 280 knots true airspeed

I won't say amazing, since its NOT! the Valor is a fixed wing, vertical take off and landing turbo prop aircraft, that's what it is, I used to fly a 1980 Mitsubishi Marquise that would cruise 250 knots easily, and the A-400 is much faster, so turbo prop fixed wing aircraft are "very fast"... the V-280 is a tilt-rotor, or just larger propellors, as such it has some technical issues and difficulties that will never characterize the Defiant, which is still a helicopter with contra-rotating rigid fixed rotor blades.. and a pusher propeller to increase VMAX....

So the Valor will NEVER be as nimble and maneuverable in the low speed regime as the Defiant, the Defiant will NEVER be as fast as the Valor....

I really question the Valor as the Army, Marines vertical lift platform, I know the Marines LOVE the Osprey, but I still think a troop helicopter for rapid insertions, still needs the Defiant's terminal maneuverability.....

At this point neither is really all up and ready. Some people have been pushing to cancel the program right now and buy V280. The problem right now for that is that V280 and Defiant lack a critical feature there final engines. Valor and Defiant are only as yet Tech demos.
Without those engines either the T900 or T901 neither form has the range of the FVL requirement.
Both have potential for use and I think the best outcome for the US DOD as a Whole is some combination of both configurations a Raider derived FVL capability set 1, perhaps a Valor based Cap 3 some true future attack platform. And a Tiltrotor based Cap 4. The fight is when the USAF and US Army start to fight over cap 5. Cap 5 was FVL Ultra which aimed to try and punch a C130J sized transport. That’s Airforce Turf and the USAF seems to want a Jet for that.
Bell to roll back V-280 funding until US Army competition

Bell plans to make no more significant investments in its V-280 Valor tiltrotor until the US Army makes a commitment to Future Vertical Lift Capability Set 1 or Capability Set 3 programmes.

After the V-280 reached its 280kt (519km/h) speed goal on 23 January, Bell believes that it sufficiently demonstrated the tiltrotor technology.

“I think our team has done everything we've asked of them to design and build a terrific aircraft. Its maneuverability is outstanding. It's been demonstrated,” said Scott Donnelly, chief executive of Bell, on an earnings call. “So at this point, look, we'll have no choice but to roll back any funding that we put into it, waiting to see what the Army is going to do, because we've done what we can do.”

The Bell V-280 Valor on its maiden flight

Bell

The Bell V-280 is a demonstrator for the US Army’s Joint Multi-Role Technology Demonstrator programme, a precursor to the service’s effort to replace its fleet of helicopters, called the Future Vertical Lift programme. The V-280 would be a contender for Capability Set 3 of the programme, which aims to replace the US Army’s fleet of Sikorsky UH-60 Black Hawk utility helicopters.

Capability Set 1 is a stated desire by the service to replace its Bell OH-58 Kiowa scout helicopters, which have been retired since 2017. Bell says it will also participate in the competition for the next generation scout helicopter, but has declined to say what its bid will look like or whether it will be based on tiltrotor technology or another concept.

Despite tapping the brakes on future investments in the V-280, Bell’s Donnelly says he is optimistic about the Future Vertical Lift programmes.

“We're certainly encouraged by the dialogue that we've had, and I think the Army has had publicly around their desire to accelerate these programs, both Cap. Set 1 and Cap. Set 3,” he says. “So, we would certainly hope to hear shortly, to start to see that those statements turn into some contracted work.”

So the Valor will NEVER be as nimble and maneuverable in the low speed regime as the Defiant, the Defiant will NEVER be as fast as the Valor....
(1)twin helicopters can be quite nimble. Thus there are no physical restrictions stoping tilt rotors from being nimble.
(2)compround rigid tilt rotors aren't just improved tilt-rotors, its more complex. Importantly, it's precisely low-speed handling of rotor blades which is being compromised for the sake of higher speed.
(3)Defiant is 'uge for its applications. It may not be obvious from its appearence, but payload volume is forward from the rotor mast. This thing dwarfs blackhawk.

So, frankly speaking, defiant, a piece of art technology-wise as it is, is a very complex pick.
And tbh, i see valor as better
