    Thank you for that. When my son was 6 (he was born in 95) he came crying to me and said “Daddy I don’t want to go to war. I don’t want to get drafted”. Almost killed me that my son had to even think about it. I did my best to convince him he had absolutely nothing to worry about. It’s a crime that the government sent sons like mine to die for absolutely nothing. They’ve been sending kids to die every since without any victories or reasons for it but a lot of people made a lot of money doing it. Our soldiers deserve to enjoy those spoils of war and I wish I knew how to make it happen for them.

    Beautiful restoration and glad to see a UH-34 still flying. Having grown up a few miles from MCAS(H) Tustin, it was a common sight to see pilots on training flights in H-34s, along with CH-46s and 53s that were based there. I will never forget my first air show at MCAS El Toro in 1966 when the Marines staged a mass helicopter assault demonstration with lots of H-34s, 46s and Huey gunships. I wouldn't be surprised if this particular H-34 had been overhead at one time or another during its USMC days. Keep on flying!

For me, the ultimate H-34s will always be those flown by VNAF 219th Squadron - the legendary "KINGBEES." 'Kingbees come now', and they always did or died trying.

Once went back and got another bird then returned to be shot to hell. We pulled left seater out dead, gunner was hit in leg and right seater had femoral artery cut. I was first up and all i saw was blood in the floor board about an inch deep. Never did find out how those guys did after they went out on choppers. We loved those guys for saving our bacon a few times.

    @Hoy Sum The engine is a Wright R-1820-84D of 1525 hp. This type also propels B-17 Flying Fortresses and proved its reliability many times during WW II. But the bombers are equipped with turbo chargers to keep their power at high altitudes whereas super chargers are used for these helicopters. That's why a B-17 in flight sounds smooth and sonorously while the S-58s/H-34s roar and rattle like most aero radials with open pipes do.

A German aircraft that was stationed very close to where I was stationed while in Germany My aircraft was converted from the H 34 to a S58E I named it EGOR and flew it nearly 20 years We crop dusted with it in California , fought wildland fires for about 10 seasons , flew it to Alaska and unloaded fishing tenders in dillingham Alaska , built power-line towers With it at Talkeetna Alaska , flew fuel with it to gold mines near Fairbanks , hauled houses with it near Dall Creek , which was above the Artic circle in the winter , recovered 28 wrecked aircraft with it near dillingham , then flew it back to California where we made some really powerful Reno Air Race modifications to its CR R 1820 84D engine giving it aprox 2000 hp then fought wildland fires with it for several more seasons This was the most reliable aircraft that always brought us home safely no mater the weather or conditions I hope to find it some day and restore it back to its pristine condition that I kept it in Dave Mahrt.

    framerate is not the issue. blades bend because of the way the sensor on the video camera "scans". this camera is no doubt using a CMOS sensor. each frame of video is scanned from top to bottom. by the time the bottom region is scanned vs the top of the sensor the blade is in a different location. this causes the bending distortion. the effect is call "rolling shutter". older CCD sensor cameras have a "global shutter". each frame is captured in one global snapshot leaving natural visual results.

    Super & Rudolph, A radial engine has it's cyliderscylinders arranged in a circle around the crank shaft. Any piston engine is also a reciprocating engine. And, if you ignore the transmission and blade clutch, gear boxes, and U-joints, the UH34d tail rotor is connected directly to the engine. If I remember my specs correctly the tail rotor is spinning eight times as fast as the main rotor.

    I think the smoke comes from burning excess engine oil that's collected in the cylinders (not so much as to cause hydraulic lock, of course). So if the engine hasn't been sitting too long since its last run, as in this case (it was leaving after just having visited a school), there's not going to be much oil to burn and create smoke.

    It sounds as though when it is spooling up, there are pauses in engine speed as though he was shifting gears. Is there a transmission with multiple gears to shift through like on a car in this model of helo?

    Not a transmission between the engine and rotor, but clutch, you have to drop the engine RPM to engage the clutch, also when you do a magneto check on the engine it will also sound like that.

    Transmission with fluid torque converter. First stage pilot revs the engine then turns on oil feed pump to the torque converter as the converter couples you hear the engine load down and the rotor begins turning. Second stage engine revs to maximum while converter continues to speed up rotor.. Then oil feed pump is switched off and engine rpm down to high idle, as the converter drains out a direct clutch is applied the 'gear shift' noise heard, engine revs are then increased as needed for ground idle or flight. These design engineers were brilliant.

  • @colindhowell

    @colindhowell

    2 жыл бұрын

    Yup, the engine-rotor clutch has a hydraulic coupling like an automatic transmission, but it doesn't have different gear speeds. There is only a single "gear ratio" between the engine and rotor (about 11.3 to 1, I think), but the nature of the clutch allows their relative speeds to vary. Once the engine and rotor speeds are in the correct ratio, the hydraulic coupling has a mechanical "lockup" which engages to provide a direct mechanical connection, for more efficient operation. The clutch also has a freewheeling feature so that it will automatically disengage if the engine speed drops below a certain point, allowing the rotor to freewheel if the engine fails. This is needed to allow a safe emergency landing via "autorotation", in which the rotor keeps spinning and the helicopter's forward speed and height are used to give the rotor enough energy to slow and safely cushion the landing.
