What do you mean Rich? This test(s) were conducted last year.

You don't think the moon landing was faked, do you?

Post by: Sean McEntee on July 08, 2014, 06:24:17 PM: I dont know about the BIGGEST UAS in the inventory. Wingspan is only a hair longer then the Grey Eagle at 60ft. Its probably the HEAVIEST with a GTOW of 45,000 lbs.

I've been wondering how long it was going to take before the Navy got onboard (no pun intended) with operating UAS off of carriers. Youtube "Shadow UAS landing". RQ-7B "Shadow" has been using an arresting hook/gear system for short field and tactical landings since it was fielded in 2001, and the RQ-5/MQ-5 "Hunter" since 1991. Still boggles my mind when I watch a computer put a Shadow (which, bear in mind is only 400lbs) on the centerline in an 20kts direct crosswind.

I am interested, however in how the added challenge of a pitching carrier deck was overcome.
Title: Maybe the largest drone ?????????????
Post by: Robert Zambelli on July 08, 2014, 07:02:06 PM: We might want to rethink large drones. I’m pretty sure that this one, the Global Hawk, has them all beat.
I can be somewhat proud of this craft in that I engineered and designed the entire drive system for the phased array scanning radar. It’s a gear reduction system with a total backlash specification of .5 milliradian.
•   Length: 47.6 ft (14.5 m)
•   Wingspan: 130.9 ft (39.9 m)
•   Height: 15.3 ft (4.7 m)
•   Empty weight: 14,950 lb (6,781 kg)
•   Gross weight: 32,250 lb (14,628 kg)
•   Powerplant: 1 × Rolls-Royce F137-RR-100 turbofan engine, 7,600 lbf (34 kN) thrust
Performance
•   Cruise speed: 357 mph (310 kn; 575 km/h)
•   Range: 8,700 mi (7,560 nmi; 14,001 km)
•   Endurance: 28 hours
•   Service ceiling: 60,000 ft (18,288 m)

ps - Steve Fitton, you saw part of the drive.

I am sure it has ACL and it calls the ball on its own. The ball is a mirror on a gyro with a light reflecting off it. So its not to hard to envision ACL (Automatic carrier landing) on this plane. F14's had this in the 70tys. Perfect guide slope is 3 degrees and that is hard to maintain in 15 foot swells by eye. Even though many pilots do this on a daily basis. They figure that you only have seventeen seconds to line up and hit the box. Not much time for corrections.

While I might have over spoke on the largest this is a fighter plane that's unmanned. Should give the competition a good run.

Sean, the Navy has been working on them since the '90s, though perhaps not making too much noise about it. An engineer friend of mind was in on the first efforts and shared some of those early projects.

Another good friend and aero engineer, flying buddy in our high school days in the '50s, just retired from advanced research projects at Northrop Grumman. He tells some pretty funny stories about pushing projects along and was very involved in the UAS lineage for several of his last years.

Post by: 55chevr on July 09, 2014, 06:05:45 AM: The Navy developed a drone helicopter in the 50-s with Gyrodyne. It was for anti submarine detection. The carrier launch and recovery is interesting. Plus this is a stealth design.
Title: Re: Us largest drone
Post by: Paul Smith on July 09, 2014, 07:04:02 AM: I guess the "biggest drone" doesn't include B-17 drones in WWII.

The thing that makes me wonder is all the people standing around in the jet blast area and the confidence they have in the landing of the headless horseman.

Live by the chip.
Die by the chip.

Post by: FLOYD CARTER on July 09, 2014, 01:04:26 PM: I sailed San Diego to Honolulu two times on USS Kitty Hawk as civilian contractor. I watched night flight ops from a side catwalk (the sailors let me do it, even though it wasn't allowed). Night ops with those fire-breathing jets is something not to be forgotten.

F.C.

Title: Re: Us largest drone
Post by: Bob Reeves on July 09, 2014, 06:05:06 PM: My unforgettable was the night a VA-212 pilot flying an A4 came in too low and hit the ramp. Front half tumbled down the deck on fire, back half landed in the fantail on fire. A carrier flight deck is not a fun place to be at night.

If your head is not on a swivel you could be blown overboard, hit with a 100 mph tool box, walk into a prop, get sucked up a by a jet engine or hit with a arresting wire. All this is happening while battling a head wind that could blow you overboard and add into the mix night ops where its so dark out you cant see the hand in front of your face. I guess its safe. That's why everyone has his place and you better be within a foot of that spot. This all happens in 12 hour shifts.

This reminds me of the old Cleveland flying field that was right next to the end of the runway at Hopkins. We camped there many times. They would advertise as "the only contest with 747's as alarm clocks." The planes would start rolling out around 6:00AM as I recall.
