Look what a CH-47 can do

Both actually. I'll let Stearman or a Phrog guy talk about dual head ops, but in general, the load on the blade has to be applied somewhere, so the next place is the blade connecting points at the hub. Not sure what the -46 or 47's use, but for -60s, they've gone to elesto-metric bearings, which are kind of a unibal/rubber band combo type device (that's my technical explaination).

One of my Det aircraft had some pretty torn up bearings when we tore it apart. My lead AD1 was telling me that it's generally due to overstressing the head while maneuvering (putting G's on the head). We both knew who the OIC who had the bird before us was, and it was agreed that that explaination made sense. Ever since then, every time I'd do a little airshow over the boat waiting for the shoes to set flight quarters, I'd usually get a glaring look from AD1 after I landed. :)

I've heard from numerous WO's that Chinook's are the best gig in the Army...whether it's true or not, eh, don't know really. What's crazy is if you pause the video when it's banking, check out all the different directions the blades are flexing forward and aft.

Ghost, It's a 53. Also, that was a CH-53A that weighed less than 30k lbs. So I wouldn't venture that todays E model can do that. I don't want to try it for sure. Rotors and flames everywhere.

Hey Ghost, we had that patch on the TR during Desert Storm. I have one on a flight jacket somewhere.

"Airshows?" Well, it depends. Speaking strictly as a small boy guy (Cruisers, frigates, destroyers), it depends on what mission is going on, what else is going on (do you need to recover quickly), how bored you are, how much of an idiot you are, and to a small extent, how cool the captain is.

There were times when the mission was as complete as it was going to get and being back at the boat a bit early or they're not quite ready for you to recover. Also, there's times when you're doing stuff right next to the boat, so it's not like you have to transit. As for being an idiot, there's cases of people outflying the aircraft and impacting things (ship, water, etc). Functional check flights are another type of flight where I would usually have time to fool around behind the boat. It's daytime, and you don't have an exact time that you know you're going to be done w/ the maintance checks, so it's a pretty short notice for the ship to recover you. You usually wait a few minutes for it to come around to give good winds. Plus the maintainers will be out on the flight deck, so they appreciate the show at times.

Okay, quick sea story that I don't remember if I've shared here. Was doing a FCF on cruise, and we finished up. Not much going on w/ the ship, mission-wise, so a lot of the smokers were out on the port side puffing away. As I'm doing pitch backs over the flight deck, my AW makes a comment about the state of the moon that morning. I tell him he's got 30 seconds to get into position while I'm turning back around. Just as long as he has his gunner's belt on. I've never seen someone get out of their vest and strip down a flight suit that fast. As we're coming around, there's a line of maintainers down on the flight deck, along w/ a H2P (and no OIC to be found, so I continue...who am I kidding, I probably would have done this even if he was out there). As we come by at about 100 feet, the AW presents butt to the onlookers. Now, I'm coming up the port side, and it's about this time I notice the Master Chief of the ship is out smoking. It's not that I worry about me getting into trouble, but he could make life difficult for the AW, so I wrap up the turn to get out of sight. Apparently it was too abrupt a turn, as the AW went flying across the cabin into a seat (away from the door). Pretty funny...at least if you were there.

The pilot flying the CH-47 is actually a British pilot. If anyone is interested in what the pilot had to say about it, visit this link http://www.runryder.com/helicopter/t116876p1/ and I can't remember exactlly but either the bottom of the third page or the top of the 4th page you can find a few posts from the chinook who accidentally found that discussion. He actually says that he flew 25 different shows with that same routine and did no damage to the tranmissions.

Come on bro, you mean you never took that pig to 90 angle of bank. If you do it right (kind of like a wing over) it puts very little stress on the airframe.

Do they still rework 53s in Pensacola? Back when I was going through VT-10 in 1983, we would watch them test 53s coming out of the NARF (or whatever they call them now). Their test pilots would occasionally loop and roll them. It was usually announced in advance at the squadron so all those able could go watch. Pretty awesome stuff.

Nope, all 53s (USMC, USN) get worked out of NADEP in Cherry Point, NC. Last time I was there, they had the USAF 53s getting SDLM'd there too. NADEP Pcola has been gone for awhile, but I still see rework parts with the PCOLA NADEP label on them, so it must not have been that long ago.
