Did they manage to make copies of the engines or was performance reduced? I understand that aircraft engines were just as bleeding edge metallurgically etc. for the time back then as they are today.

The Tu-4's engines actually weren't reverse engineered things, they were developed independently (though I think they did copy the boost system). The Russians were pretty good at building giant radials.

The metallurgy thing was a much bigger deal for the airframe; the Russians didn't have some of the cutting edge stuff Boeing had access to, but they were damned if they weren't going to copy that thing rivet for rivet, so instead of modifying the design they just lowered the strength requirements, because Russia.

Even better: In the 1980s, Russian's visited a Lockheed plant and applied a sticky substance to their shoes in order to collect metal shavings on the floor to get metallurgy from.

It might have been.

EDIT: The British GAVE the Soviets 20 jet engines that they reverse engineered.

quote:

The major problems inside MI5 concern its relationship with the former Prime Minister Harold Wilson. As the Minister responsible for trade in the Attlee Government, he attempted to increase exports to the USSR. He constantly ran up against United States Government opposition towards any growth in such trade. Wilson felt that the United States used the hysteria of the cold war to prevent Britain from increasing its trade with the USSR. His was not a position that was likely to be viewed with favour in MI5. In fact, there was near hysteria in MI5 when he was sent to the USSR to negotiate the sale of 20 advanced jet engines. Wilson was only a junior Minister carrying out a Cabinet decision, but from that point on he was viewed with suspicion by MI5 officers.

The Attlee government wanted to be friendly with the Soviets and decided the best way to do this was to sell them what was at that time the world's best jet engine; during the negotiations some Russians visited the RR plant and did the "metal shavings in shoe" trick.

I'm patiently shopping around for Grumman AA1's as I finish up my Instrument Ticket and I came across this blog with some AA1A posts from the nineties

Here's a sweet post about some "Mondo lift" over the Sierra Nevada's

Steve Williams posted:

Last week I flew the orange airplane from Hayward, in the San Francisco area, down to the Los Angeles area to visit relatives. Both during the trip down and the trip back included surprising events affecting the performance of the 26-year-old two-seater.

The trip down to L.A. is quite a pain in the Trainer, because several ranges of mountains are in the way -- the largest at the end of the trip just north of L.A. The return trip is even more inconvenient. At least on the way down I have plenty of time to cruise as low as 3,000 feet, burning off fuel, before climbing over one of the passes. But on the way back I must climb immediately after departure in order to fly anywhere near directly from EMT to HWD. It is possible to first fly west to Santa Barbara and complete the whole trip home at no more than 3-4,000 feet, but it's slightly out of the way.

With just me aboard and full fuel, the orange airplane cruise-climbs fairly well below about 4,000 feet at perhaps 105 mph. From 4,000 to about 8,000 I must slow to 90 mph or less, and depending on the air I sometimes can't maintain 500 fpm. Above 8,000 I'm step climbing -- I'll level and accelerate and then gradually pull the nose up, maintaining 2-300 fpm to perhaps 80 mph, and then try to accelerate again without losing altitude. Like I said, a pain. (Remember that this is the original 108-hp engine.)

Departing last Wednesday, the winds aloft were forecast out of the north from 20 knots at 3,000 feet to over 40 knots at 9,000 feet. They seemed stronger than forecast down low. Climbing to 5,500 southeast through the Santa Clara valley, I was indicating about 100 mph, but the ground speed was often 140 knots. Pretty nice. I leveled at 5,500 and dodged the head-on Southwest jets inbound to SJC. Southwest chose such a nice color for their airplanes!

Apparently pilots and controllers were concerned about turbulence, because they kept chatting about flight conditions. My weather briefing didn't concern me -- just the usual warnings of occasional turbulence below the moon. The ride was smooth, although I was flying through patches of lift and sink.

The first surprise came at Priest VOR (ROM), 115 nm southeast of San Jose. Priest lies at 3,880 MSL, on a peak of the mountains west of California's central valley. (Those who know the orange airplane are wondering how I knew I was at Priest. Simple: I looked out the window!) I flew into another bit of lift, and trimmed the nose down a bit to maintain altitude, taking advantage of the momentary boost to gain speed. The throttle was fully open, and the RPM right around the red line. The plane continued to climb, now at 1,000 fpm. I pitched down more, and was forced to close the throttle a bit as the engine wound up. Finally, I realized that this wasn't just another little area of mild lift, but a major elevator ride, and I might as well take full advantage. "31 Lima's climbing." "Last called Oakland center, say again?" "31 Lima, we're in, um, some mondo lift here, and we're going to ride it on up." "31 Lima, roger, no traffic." I never can figure out who this Roger guy is.

I pitched up to about 2,800 RPM and gradually opened the throttle. At one point the VSI was pegged at over 2,000 fpm, but it didn't last long. I didn't look at the clock, but I believe I leveled at 7,500 after less than a minute. If the high mountains were closer, I'd have circled in the lift, as some of you have seen me do to escape the Sierra. But in this case I continued, and soon was out of the lift and into sink, pitched up to 90 mph just to hold 7,500 feet. Later, I step climbed normally to 9,500. At one point the controller advised another aircraft of the lift over Priest. As it was rather an unusual advisory, the pilot asked for clarification. Finally, the controller said, "Well, actually, it was reported as 'mondo lift.'" (Sorry, I had keyed the mic and just couldn't think of any other words at that moment.) The pilot understood. Another pilot apparently didn't. "Oakland center, where's that turbulence reported?" The controller tried to explain. Then I called back. "Oakland center, 31L, be advised the ride was smooth the whole time. It was just an area of very strong lift." That seemed to calm down the other pilots.

I flew over the mountains between New Cuyama and Santa Paula, north of Santa Barbara, and turned east toward the destination. There were a few bumps in the mountains, but nothing serious. The ground speed had stayed up over 140 knots for much of the trip. I began a 200 fpm descent just past Burbank. I've grown fond of these long, slow descents. It seems that in the two-seater one has the choice of descending normally at 500 fpm for only a few minutes, which requires pulling back the throttle to keep the propeller blades from flying off, or of descending over many miles at 200 fpm, with the engine at a more reasonable RPM. The slow descent is plenty to really get the engine spinning, even at high altitude, and to get the airspeed up to the bottom of the yellow arc around 140 mph. Between Burbank and El Monte I still had part of the tailwind, and so indicated some impressive ground speeds. The ride got progressively rougher as I descended near the mountain faces.

I usually arrive at the airport traffic area really high and fast, because there's never any problem slowing the two-seater for the arrival. Reduce power even 500 RPM, and one can slow to the white arc within seconds. Those stubby wings are great for sporty handling, but they aren't terribly efficient at generating lift. El Monte asked me to report a right base over the Santa Anita racetrack perhaps five miles northwest of the airport. I arrived there still turning red line RPM, 1,500 feet above the pattern and descending now at 1,000 fpm. I realize this isn't how your instructor taught you to politely enter the pattern, so I always make sure I'm aware of ALL of the airplanes in the pattern, and I am always prepared to get out of their way if my unusual arrival would be inconvenient for others, especially students and instructors. Many times I've had to climb above the ATA or turn away and reenter the pattern at a more sedate speed, but usually it works out. (And, no, I don't believe in shock cooling.)

I landed at El Monte, after 301 nm in 2:24, 125 knots block to block.

After a nice visit with relatives, I departed El Monte on Saturday. I couldn't raise SoCal approach, so I was forced to fly north of Burbank, again quite near the mountains. The ride wasn't bad, and after finally establishing radio contact I climbed into the Class C over San Fernando. I was at 4,500 feet over the 3,750-foot mountains west of San Fernando when it happened again. The ride stayed smooth, but the VSI started spinning. I rolled the trim wheel forward and reduced throttle. "SoCal approach, 31 Lima's climbing." "31 Lima, uh, um, say your type again?" "31 Lima, Alpha-Alpha-One." (The ATC book doesn't have AA1A.) "Okay, I see your ground speed at 135 in a climb, and I thought that's the best-performing Yankee I've ever seen." "Yeah, I wish it'd last all the way to Hayward." Another pilot chimed in: "I gotta get me one of those." The VSI was pegged, and I leveled at 6,500 after perhaps 30 seconds.

I continued westbound past Santa Barbara, and turned northwest into a mild headwind to follow the freeway to San Luis Obispo. I knew I couldn't make Hayward in a headwind without getting fuel. I didn't like the fuel situation at Santa Maria or Paso Robles when I stopped at those cities on previous trips, so SBP seemed a good place. Also, I missed last year's AYA fly-in to SBP, and this year's was rained out, so I wanted the chance to see why everybody says it's a great place to fly into.

Having cleared the high mountains, I reasoned that I might as well descend right away into lighter headwinds. I began a 200 fpm descent, winding it up to the top of the green arc. The descent lasted all the way to SBP, and I didn't pull the power until short final. SBP really is as nice as they say. Quick fuel, and a nice restaurant. From the pattern, you can see mountains, ocean, and strange, abrupt peaks within a few miles of the runways. I climbed up the freeway past the California Condor nesting sanctuary on the right and the 3,000-foot towers on the left, and leveled at 2,900 for the rest of the route home. After Paso Robles, the direct route took me away from the freeway over a striking expanse of washboard hills. Ranches dot the hills, and the grass for grazing is broken only occasionally by trees. But as the sun descended, the terrain relief became more pronounced, and I was not at all convinced a forced landing would be terribly easy, especially considering the long walk or the long, cold night that would follow. I could have climbed, but as it was I would be arriving in the Bay Area after the sun set, and the rapidly cooling air often becomes hard to see through.

I flew east of Pinnacles National Monument in the dusk, and was relieved to be able to again follow roads into Hollister at the south end of my home valley. Bay approach was cooperative for a change, and I again waved to the Southwest passengers in their little windows as they flew by in their big orange airplanes. The mountains east of San Jose disappeared into the haze and dark before long, and I descended by reference to the red lights on the tall towers and the headlights on the freeways. Hayward and San Jose ATIS called the visibility five miles. Finally, about seven miles out, the HWD PAPI appeared, and I followed the four bright red lights to land after about 3:00 in the air (not counting the stop), about 100 knots over the route.

It was a beautiful trip. I didn't manage Tiger speeds, but somehow that doesn't bother me. I'm amazed at how often lift plays a role in an airplane with so little resemblance to a glider. And there's a real feeling of accomplishment to completing a trip over mountains and broad areas of desolate terrain in the most basic aircraft.

Around the time that the Curiosity rover landed on Mars, which was also not long after the recession, there were tons of posts on Facebook from people complaining about the waste of money. "We have enough problems at home! That money should be spent HERE ON EARTH! Give it to people who'll get us JOBS!!"

(That was coincidentally about the last time I used Facebook.)

So from that bit of data, I can conclude that a large number of Americans believe that NASA has no employees, benefits no one here on Earth, and every time we launch a rocket it's filled to the brim with bundles of cash to be shot into space.

It was an interwar design meant to be a bomber and a transport, with compromises that hurt both missions. E.g., two hydraulically powered turrets in the nose and tail that were undergunned (each with a single .303) that weighed the plane down when being used for transport. Range was 880 miles unless you installed the supplemental fuel tanks in the fuselage, which meant less bombs/cargo/pax. The wing was complex, the production was relocated and by the time the first ones arrived in 1939 (4 years after their first flight), they were already obsolete. Except for one unit in England that had them for two months in 1940, all saw service in Africa. As bombers they were replaced by the Wellington in 1940, and as transports by mid 1943 by Hudson IIIs and C-47s. Not actively bad, and better than the Valentia biplane that it was intended to replace, just not up to snuff.
