Copieum. lots and lots of copious amounts of Copium. CH53K is a heavy lifter this is a medium lifter. Next the T700 is a family of engines one of which is the T901 with 300shp currently slated to reengine Blackhawk and Apache.
the engines slated for Valor are derived from the AE1107 already in Osprey which delivers 6,000 shp and was developed in 1986. In fact they looked at putting the AE1107 in CH47. Boeing decided to go bigger and is currently offering to put the GE T408 in it with 7,500 shp in the Chinook.
Next comparing V280 to V22 is like comparing a an IPhone 14 to a Palm pilot.

The Black Hawk is a medium lifter. Like I said it has two engines with 1,890 shp each. The V-280 Valor will have two engines with 7,000 shp each. It is no medium lifter. CH-53K will have just 50% more engine power than V-280 Valor. This is similar to difference between Merlin and NH90.
Just so that you know, the CH-53E was considered a heavy helicopter and it had three engines with 4,380 shp each. i.e. it had less engine power total than the V-280 Valor.
Good luck manufacturing 2000 of these things like they claim they will do. More like 200. And it won't replace the Black Hawk. Much like the V-22 has issues landing on anything but prepared pads, this will have much the same problem. Try to land on an unprepared surface and it will kick up so much dirt that the pilots won't even be able to see outside the windshield.
This is just a V-22 Deluxe.

V-22 Engine exhaust points down. V-280 does not. It's exhaust points parallel to the ground.
They are both tiltrotors. At best the V-280 might use more modern materials and be more mass optimized than V-22. V-280 also does not need to be optimized for naval use either. Probably. If it does not need the compact storage configuration that will likely reduce weight.
Transformational growth in US industrial capacity related to military activities is currently happening

NH90 and EH101 are both medium lifters to.
The increase in power was dictated by lessons learned in High and Hot. The US Army wants a aircraft able to operate from negative sea level to the top of the world with a full payload. That’s why so powerful.
We should all be well aware CH53E had such yet we should also remember that it was designed under a different circumstances of doctrine and technology. Particularly needs of range speed altitude and payload for an aircraft of the 1970s vs the 2020s. I mean Half a century and you still think the same exact capabilities are modern?
he is correct. This reduces the need for prepared pads which are only needed when the craft regularly uses the same landing zone due to the high heat of the engine exhaust. However It’s also common helicopters due to any number of reasons including as your other complaint applies. The effect you describe is a known brownout condition which is actually fairly common in modern helicopters. Which is why many are now sporting radar and electro optics.
Yes Both are Tiltrotors which though they have some unique aspects, are not in vertical operations much different than helicopters. V22 is a medium lifter V280 is an assault helicopter. The two were designed for different purposes. V22 is more of a cargo vehicle. It has a larger troop load and cargo hold it made trades to be navalized. V280 is designed for faster speed higher, altitudes and as an assault and potential attack platform.
Your pessimistic assessment I place a lot of doubt in as first. V280 is built on the shoulders of giants. The V280 is a second generation tiltrotor as opposed to Osprey and AW609 which are first generation Tiltrotors.
v280 takes the lessons learned and has a different design as a result. Even the known transmission issues that still plague V22 may not be present in it due to the V280s mechanism. Second this isn’t limited to the propulsion alone. It’s built on off the shelf technologies. Technology pioneered in the failure of the past.
Third as the missions of the 21st century inflict a higher emphasis on range for missions, Speed for ingress and egress, altitude for survival than existing rotorcraft offer in the military sphere. FVL program was designed specifically for this. Hence the higher hot and high requirements pushing more powerful engines, higher payloads as more systems are standardized again more powerful engines.
Next as to the scissor folding it’s possible that the production version will have it. The USMC and US Socom are both very interested in the V280 along with other US Allies for use in maritime operations. That means it has to fit aboard ships which is what the scissoring allows. If you look at V280 In profile it has the same hump like wing box and Bell has done multiple models and renders showing they intend to offer that feature. Though on the face of it the Army might not need it to a degree it would still be present as the wing would have to come off to allow shipping in the case of a disabled craft aboard C17.
The point I was trying to make is that NH-90 and Merlin are both considered medium helicopters. But Merlin has close to 50% more engine power than NH-90.
You claim CH-53K is a heavy helicopter and V-280 Valor is a medium tiltrotor. But the thing is the CH-53K, similar to those other helicopters I mentioned, has 50% more engine power than V-280. The truth is both are heavy vertical transport aircraft.
V-280 Valor has over triple the engine power of the Black Hawk. So it is certainly NOT in the same payload class.

I don't think that matters, as the V-280 is meant to have considerably more capability over the previous generation of helicopters it replaces. This is why it has a radical design departure over the Blackhawk, as the Army believes the missions and environments of the future require far greater capability.
Think about it like this: If this helicopter as successful as they hope (2000+ produced), then the performance characteristics it has will likely influence helicopter design world-wide. For example, maybe having greatly more engine power over the Blackhawk will not be seen as a big deal, and the Blackhawk and other helicopters might be viewed as outdated or very limited.
