Jim -----Original Message----- From: owner-rocket-list-server@matronics.com [mailto:owner-rocket-list-server@matronics.com] On Behalf Of Boyd Braem Subject: Re: Rocket-List: 2 blade --> Rocket-List message posted by: Boyd Braem <bcbraem@comcast.net> I apologize, but I get 2800 rpm not 2350. GPS ground track speed is usually between 180 and 220 kts (if I'm trying to conserve fuel at 11,500/10,500) ). I've had it up to 293 mph (+10% for Vd max--in a shallow dive). Usuall cruise setting up here are 19 MAP and 2100 rpm (I have a ram air inlet to the Bendix injection box)--that's about 55% power (170 hp) Have a nice Christmas. Boyd.

Unfortunately, it has a 4" prop extension and Hartzell recommends not to exceed 4 Gs or do "frequent gyroscopic maneuvers".

But, the "tow truck"--actually, that's how I got my first training jumps in the Navy--it was so incredibly stupid--but we had to run behind a pick-up truck out in the boonies untill the 'chute caught enough wind to inflate and start going up. Then we pulled the D-ring when we thought we were at 500". The guy in front of me (alphabetically) landed hard and broke his ankle--so, all these people were rushing over to him as I was coming down--what a joyous experience.

    Subject: 2 blade
    --> Rocket-List message posted by: "Jim Stone" <jrstone@insightbb.com> Thanks Boyd, 4 g's should be enough but I hat to have it as a limit. I pulled 5gs once while flying Mark Fredrick's so 4gs will become a limit so to speak. I wonder if the J twist has the same limit?

    Subject: Re: dead stick F-4
    --> Rocket-List message posted by: Morocketman@aol.com Do Not Archive I was thrown back to 1969 when you asked about dead stick landings in the F-4. Had my old F-100 cruising along at FL310 when my wingman just passed me. I said, "What the h#%& does he think he is doing?" Then I noticed that he had deployed his speed brake, and was still passing me. About that time I said, "What the h#%& is wrong with my Slick and Shiny Super Saber?" Then engine instruments ever-so-slowly started to unwind, and my answer came ever-so-slowly to my fuddled brain, you have just FLAMED OUT! Fortunately, I was very close to a friendly Air Force Base, and arrived directly overhead at about 20,000 feet. Our Flame Out Landing Procedure was a 360 degree circle in which the "SLED" was supposed to lose 10,000 ft. (In tests the F-100 was found capable of descending faster than a grand piano with the lid strapped shut.) In my quick survey of the problem, I realized that I had a practice flame out pattern in me, to be followed by the real one. Below 15,000' the thing was supposed to relight anyway. So I tried one at 20,000', and low and behold it fired up. The wingman then made the comment of the day, suggesting that I continue the flame out pattern "just in case." Long story short, the thing flamed out and re-fired four more times accompanied by very bad noises. At 2,500' on the base leg I announced that another BURP by this J-57, and this bird was going on alone. I raised the ejection trigger guard on the seat, and continued to a 230 knot final approach (198 knots would have been normal). Landing was normal, albeit exciting, a little aero-braking and I got a good chute at 178knots, then crossed the barrier with 1,500' remaining at about 80 knots, and stopped just before the end of the runway. The engine ran for about 1 more minute, and then puked it's insides out in the de-arm area. I did not know they had so many turbine blades in there. Cause was center main bearing failure. One final note, which I DID KNOW all along, the Ram Air Turbine is inside the intake duct on the Hun, and when you flare, the air stops, the R.A.T. stops, and you stop controlling the airplane without hydraulic pressure. The Dash One strictly prohibits engine out landings! Fortunately, mine was running when I needed it. Thanks for listening to an "old fart fighter pilot" reminisce! Let's not do anymore dead stick landings, Les Featherston DO NOT ARCHIVE

    Subject: Re: 2 blade
    From: Boyd Braem <bcbraem@comcast.net>
    --> Rocket-List message posted by: Boyd Braem <bcbraem@comcast.net> The g-limit is caused by the prop extension, not the blades. When I was younger (what a phrase!) I could do 8 g before my vision started to grey-out. At the moment, by body is perfectly happy with 4 and you can do just about anything (maneuver-wise) at 4 g--non-competition, that is. Actually, my "things to do list" has a note to call Hartzell and ask if I can substitute the J blade for my D blade. I upgraded my prop hub, last year in accordance with the AD. Boyd. I think Mark has (had?) the same prop on his Rocket--I haven't seen his plane for a while, so I'm not sure if he's upgraded. do not archive On Sunday, December 7, 2003, at 03:03 PM, Jim Stone wrote: > --> Rocket-List message posted by: "Jim Stone" <jrstone@insightbb.com> > > Thanks Boyd, > 4 g's should be enough but I hat to have it as a limit.

    Subject: Need Vacuum Gyro Horizon
    --> Rocket-List message posted by: Morocketman@aol.com Hey all you Rocketeers out there, with everyone installing Dynon D-10's does anyone have a vacuum gyro horizon for sale. I would really like one with the vacuum warning flag built into the instrument, but will consider any units available. New, Used, Rebuilt, Repairable! By the way, I really like my D-10, but going IFR (not light IFR) without both electrical and vacuum horizons scares me. Please reply off the list! Thanks, Les Featherston 417-466-4663 DO NOT ARCHIVE
