CTR makes several valid points on post #155 and to add to this, Sikorsky is now wholly owned by LM, whose share price has risen impressively these past few years in-spite of major US defense spending cut-backs and is a very different beast from UTC (whose share price took a major hit following the decision to sell or spin-off Sikorsky, and has yet to recover).

What makes me smile is that for the current FVL JMR-TD Medium/Utility program, the SB-1 is a 50/50 JV with Boing () and Sikorsky (a company wholly owned by LM) and the Bell V-280 Valor has LM as a major partner.

Were it a 50/50 JV on both programs, then one would think the DoD would raise competitive pricing concerns, as one company could be seen as a win/win bidder whatever the outcome, but not knowing what value share there is on the Valor program (but likely less than 50%), then one could question whether this bidder has a preferred platform solution .

As for the S-97 Raider, I still don’t see anything else to compete with it on the JMR-Light option, so I don’t suppose either Sikorsky or LM is that worried about any lack of Raider press releases just now and logically any of the data coming out of the Raider program is being fast tracked to the Defiant platform.

The main reason for the 97 was as a demo/risk reduction for the Defiant when it was to fly in 2014. To meet the JVL schedule Defiant's design had to proceed without any 97 input. So now Lockheed has decided it is irrelevant and appears to have defunded it. Makes the Defiant program very risky compared to the V-280 which is building off of XV-15, V-22, and the 609.

The latest copy of Av Week provided a brief program update:
  • Nine flights to date (since May 2015)
  • Latest flight was performed with the gear retracted, for the first time
Meanwhile, the B-21 has appropriated its name...

Excellent, we were due for some news! I'm off to Udvar-Hazy for the X2 induction, hope to hear more in person.

There's also a football team in Oakland who may wish to have a quite word on the subject ...

Maiden flight (1.0hr): 5/22/15

4 month hiatus

Second flight (1.2hr): 9/29/15

Hiatus to accumulate 200 hours on PTSB (15-20 hr/wk) @ 32 hours 9/29/16 = 9 weeks?

7 total additional flights in 12 months

AC2
No flight time?

Sikorsky posted new video. Looks like still limited to low speed runway work after 18 months when they stated full envelope by summer 2016 in their last program delay update.

Sultan, it might be possible that they are taking a cautious approach with new tech, a caution possibly reinforced by the tragic loss of that 525 a few months ago in Texas.

@SansAnhedral Making it work to a modern spec and modern requirements is indeed reliant on new tech, and new materials, as well as making them work together effectively. Likewise, requiring "new" is the effort to scale up from the X-2. You will note that those vintage efforts each was not successfully pursued at the time. Tradeoffs, etc.

Is this really another 4+ month hiatus?

Are there MGB issues? Vibration? Are the supplier-built composite blades or flexbeams delaminating/cracking/failing?

My money is on the latter.

Approaching 2 full years since first flight, this is beyond suspicious.

Sans, what might be going on is that (with being part of LM now) the focus on design work is being directed to the next size up aircraft that is to compete with V-280 Valor. Maybe. No idea.

Lone

Your hypothesis is unlikely. The 97 has not left the airport grounds that I know of as Sikorsky would drop another video of that great achievement. After all the money spent if it was safe to fly anyone would take the opportunity to shake down the flight controls, basic design concept, or get PR. It was originally a concept demonstrator and risk reduction tool. The fact that it has done none of these points to major design issues.

Or they are just flying over the swamps of Florida using it as a risk reduction tool for SB>1. It seems likely that they haven't met their flight test goals yet (I would expect a video and announcement, too), but I suspect progress is being made and they're just radio silent.

I know the flight test programs I've been associated with never made progress as public as I would have liked, lol.

You won't find me being a huge champion of outsourcing critical dynamic components :-/

I bet if somebody at Sikorsky made a decision to do that they came from another company!

The X2 and S97 blades (and some other S97 rotor components) were designed and built at a supplier in Virginia

Built, yes. Designed, no. They did a nice job on the X2 blades. The decision to send them out did not come from a life long Sikorsky employee!
