I can see this work as a strategic/ slight tactical transport, however how it should replace the Blackhawk and Apache in the real tactical role, requiring very low level manoevering, quick stops, fast insertions and extractions..... well let's just say I am curious how it performs in this part of the flight envelope.... that it can fly far and fast is nice, but is only a part of the required performance I guess. |

I concur. My friends from the 609 program are the same engineers that oversaw the V-280 system installations, and they followed the same bird strike survivability design requirements as for an FAA certified aircraft.

...but would buying both not be the best option for the US Army? Common engines (I think?), potentially commonality in avionics, but different platforms for different missions. Not to mention, keeping the ability to manufacture military helicopters alive in two rather than one organisation (accepting that each involves multiple players). The SB1 looks like a much better replacement for the Apache than the V280, but on the other hand, the V280 looks very good as a Blackhawk replacement... |

Good point about the AW609. Looking at the picture below shows that area of the AW609 to be fairly well protected from impacts with the nacelle tilted vertical.

"Well protected" perhaps from prying eyes only. In the event of a birdstrike, the thin fiberglass nacelle fairings might well as be made of a wet paper bag. They will do nothing to attenuate the energy.

Bell V-280 Valor Achieves First Flight - Bell Helicopter (news) Bell V-280 Valor Achieves First Flight Amarillo, Texas (December 18, 2017) – Bell Helicopter, a Textron Inc. (NYSE: TXT) company, today announced that its V-280 Valor has achieved first flight. The V-280 Valor is a next-generation tiltrotor that is designed to provide unmatched agility, speed, range and payload capabilities at an affordable cost. This milestone represents exceptional progress on the V-280 development program and brings Bell Helicopter one step closer to creating the next generation of vertical lift aircraft for the U.S. military. “This is an exciting time for Bell Helicopter, and I could not be more proud of the progress we have made with first flight of the Bell V-280,” says Mitch Snyder, President & CEO for Bell Helicopter. “First flight demonstrates our commitment to supporting Department of Defense leadership’s modernization priorities and acquisition reform initiatives. The Valor is designed to revolutionize vertical lift for the U.S. Army and represents a transformational aircraft for all the challenging missions our armed forces are asked to undertake. “We are thrilled to share in this success of the V-280 first flight with Team Valor,” added Snyder. “The V-280 intends to completely transform what is possible for the military when it comes to battle planning and forward operations.” The Bell V-280 Valor program is part of the Joint Multi Role Technology Demonstrator (JMR-TD) initiative. The JMR-TD program is the science and technology precursor to the Department of Defense's Future Vertical Lift program. The V-280 program brings together the engineering resources and industrial capabilities of Bell Helicopter, Lockheed Martin, GE, Moog, IAI, TRU Simulation & Training, Astronics, Eaton, GKN Aerospace, Lord, Meggitt and Spirit AeroSystems—collectively referred to as Team Valor. The Bell V-280 Valor is postured to provide the U.S. Army with the highest levels of maturity and technical readiness. The aircraft is designed to provide the best value in procurement, operations and support, and force structure, while delivering desired leap-ahead performance capabilities with increased maintainability, reliability and affordability to the DoD. With twice the speed and range of conventional helicopters, the Valor is designed to offer maneuver commanders unmatched operational agility to self-deploy and perform a multitude of vertical lift missions currently unachievable in one aircraft. The Bell V-280 is a combat force multiplier with superior performance, payload, survivability, and reliability to give the warfighter the decisive advantage. |
Wow! Congrats team Bell!

Program Update Video
At this rate Bell will have completed airspeed envelope expansion before SB even runs the replacement for the crashed S-97. Impressive progress in only 5 months. |
First public flight demo
https://www.defensenews.com/land/201...c-flight-demo/ Interesting factoid noticed in this article In cruise mode during the demonstration, the aircraft showed it has a much lower acoustic signature than a V-22. |
V-280 Valor Retracts Landing Gear
While not as exciting as the SB>1 registering a tail number with the FAA, the V-280 achieved gear up flight last week. Clearing the path to 280 Kt cruise speed.

V-280 flights are showing up FR24 now it looks like Today had a 1:45 flight @ ~11,500ft flight getting up to 259kt GS, not bad |
Ferry flight rumored for tomorrow the 18th. |
|
Good video of V280 demonstration flight in Arlington
https://www.star-telegram.com/news/l...220650710.html |
Much quieter than the S-97 in the flyby. No obnoxious tail fan noise. Like the 609 the engine is the main noise in airplane mode. |
One year anniversary

It is a very impressive looking machine - and Bell has done very well in getting this far this quickly.
But I wonder about that full width glass panel - and the DAS system - is that going to be on initial models, or planned for later or only Spec Ops variants? Couldn't see any standby steam gauges - maybe they were out of shot. These machines aren't going to be cossetted JSFs on carriers or airbases - they'll be dropping troops and operators in the dust and be worked very hard. Having sat in a few RAAF Blackhawk RH seats (on the ground) and ridden in RNZAF UH-1Hs over the years - serviceable but battered and worn instruments and hardware were the norm. Let's hope they build those sensors and panels tough. A map with a bullet through it is still a map... |
Maybe it's just me but I don't get it. The Osprey has a great record for killing folks and a horrible record for safety and we want to follow that path for development? Nothing wrong with improving what we have, this is not an improvement but it is taking a step backwards.

The V22 has not been much in the news lately for any accidents even though it seems to be flown fairly extensively, even at high profile events such as Fleet Week here in NYC. Perhaps the design concept has shaken down sufficiently and is now achieving promise. |

Today, the V-22 has a better safety record than all other military helicopters and is the preferred method of transport for special ops and VIPs. |
Low Speed Goals Met
From AvWeek: Bell has achieved Level 1 handling qualities with the V-280 Valor, demonstrating that the advanced tiltrotor has low-speed agility that matches or betters that of the Sikorsky UH-60 Black Hawk ... |
Bell posted this video of the V-280 performing Level 1 handling quality flight testing. Impressive considering the size of aircraft. Especially in light that the Blackhawk does not achieve full Level 1 performance. |
Increased V-280 Activity
Been a lot of activity in last few weeks with much of it apparently being demos and training. Rapid takeoff with high bank angle turn into pattern looks awesome, but most impressive is the high speed low altitude airplane mode pass over the Bell hangers. Apparently a big demo to the Army brass going on right now. Anyone know if this wraps the program as they have exceeded all program goals with nothing left to prove? |

As to your post: the Bell PR office is looking for new copy, I guess. The aircraft is performing well, so hyperbole seems unnecessary. |
Sultan, you are slipping, it's nearly a year since you put 5h1t on Sikorsky on this thread.
Lift your act, or Bell will stop paying you royalties. |

AC The FVL program that covers the V-280 and SB-1 started in 2013 and was originally scheduled to end in September 2019. The V-280 basically met all of the program milestones. The SB-1 apparently still has not progressed much beyond hover. The latest Marine RFI has scheduled a Nov - Jan response window with the requirements being derived from the original program’s results. It is not the fault of Bell that Sikorsky has nothing from its SB-1 effort. As the program was originally scheduled to end in Sept and the requirements for the production version have been defined it seemed logical that the 280 would rap up with a big demo to program stake holders (like flown today). |

in his defense, Defiant hasn’t publicly done anything in half a year... so nothing new to crap on.
This is all before they even approach the real colossal hurdle, which is the vibration outside of static hover. The Defiant program is an unmitigated disaster to date. |
Sans, Any idea if the transmission problem is directly related to the ABC concept? Simplistic analysis would say as you grow an ABC in size the rotor moments (which are already in the extreme on smaller versions) go up significantly while Xmsn case stiffness goes down. At some point the mast bearings can’t handle the loads or deflections become so high the case breaks or gear alignment is impacted. Or is it they just can’t manufacture gearboxes like on the CH-53K? |

In other news, it appears the V-280 is going to be flying at the Fort Worth Alliance Air Show in 2 weeks. https://cimg3.ibsrv.net/gimg/pprune....9e637d6708.jpg |
Bell’s best V-280 video yet. |

Another View
Flyby at 12:00. Was worried they aborted when they returned to the flight test center immediately after takeoff, but they were just returning to meet up with their chase jet before departing to the show. Imagine needing a jet trainer/attack jet to keep up with a rotorcraft. What does Sikorsky use? A Cessna 172? https://m.youtube.com/watch?v=u4jvQzx2CZY&t=685s#fauxfullscreen |
It's an impressive looking machine.
I wonder if they'll start hanging weapons off it...? |
The V-280 flew more over the past 4 days than the Defiant has flown in its existence
