US Army triggers design competition for future attack reconnaissance helicopter
The U.S. Army has kicked off a major design competition for its Future Attack Reconnaissance Aircraft by releasing a request to industry on Oct. 3 to submit plans that could lead to a chance to build flyable prototypes in just a few years.

The service, in June, released a draft solicitation, that outlined its intention to get two different helicopter prototypes flying in 2023.

First flight for Defiant delayed to 2019
The Sikorsky-Boeing Defiant design will not have its first flight in 2018, following a technical issue discovered during ground tests.

Rich Koucheravy, Sikorsky director of business development for future vertical lift, and Randy Rotte, Boeing director of global‎ sales and marketing for cargo helicopters and FVL, revealed the delay in a call with reporters Wednesday.

“We are going to slip our first flight into early 2019. While it’s not necessarily, I’m sure, what a lot of folks would have liked — it’s not necessarily what we would have liked — we continue to build confidence in our configuration,” Koucheravy said.

The team initially planned for the system to fly in 2017, but that was delayed following an issue with the manufacturing of the system’s blades. (The executives said that issue has now been resolved.)

For months, the expectation had been that first flight would then come before the end of the year. But while running the power-train systems test bed — essentially, a full-scale design of the system that is bolted to the ground — engineers discovered a series of issues that caused them to hit pause on testing the program.

“We have had a couple of small things. I won’t get into the exact pieces, but it required some repairs, just some kind of mechanical repairs,” Rotte said when asked for specifics on the issue that caused the delay. “The latest ones required about two to three weeks of going back in, fixing those pieces, putting them back on the aircraft.”

“It’s nothing that requires a redesign of major components or any of those pieces. it was just, candidly, some interactions that the models perhaps didn’t all capture,” Rotte said, adding that the ground tests should restart sometime in the next week.

The Sikorsky-Boeing team wants to get 15 hours of flawless test results from the ground-based system before that first flight, and the executives indicated the first flight should happen fairly early in 2019.

Sikorsky-Boeing team rolls out Defiant ahead of first flight
The event, which took place at Sikorsky's West Palm Beach facility in Florida, marks a major milestone ahead of the first flight, which is expected in early 2019. The helicopter will first be fitted with the aerodynamic rotor hub fairings that were missing from the roll-out.
Weighing 6,000 lb (2,722 kg) and accommodating a crew of just two, the X2 was significantly smaller than the 32,000 lb (14,515 kg) and up to 18-person Defiant.

Kommt mir der Heli nur so kopflastig vor oder könnte das echt zum Problem werden?
