Early in the video, it is mentioned that early jets had poor "climb performance" - to be clear, the issue was that early jet engines could not throttle up and down quickly. To change from "0% thrust" to "100% thrust" took a long time - many seconds. Some very early jet engines could take more than a minute. That means making rapid throttles changes are impossible. While top speed was high, and even maneuverability was good, dogfighting often requires rapid changes in throttle, which jets were bad at. Piston engines can *VERY* rapidly change throttle settings (think about how quickly your car can go from idle to redline when you floor the pedal in neutral.) The Navy specifically wanted rapid throttle change because when coming in for a landing on an aircraft carrier, the plane needs to be at low/idle throttle, but if they miss the arrestor wire, they need to throttle up to 100% very rapidly to be able to lift off again before running off the end of the deck. Something jets of the time couldn't do - if an early carrier jet missed an arrestor wire, the pilot would eject and the plane would dump into the sea off the end of the carrier deck. The Thunderscreech's big benefit (as mentioned ~8:40) is that they could change the blade pitch to run the jet engine at one speed and change the amount of thrust it was producing by changing the propeller pitch. So it could have the speed of a jet, with the rapid-thrust-change of a propeller plane. In the late '50s, early '60s, jet engines were developed that could rapidly change throttle, allowing for full jet fighters to be more reasonable for use on carriers.

It is just one of the two coupled turboprop engines, but it is still pretty fascinating in a horrendous way. It was described as a 'mechanical nightmare' to route the power through the two driveshafts from the rear of the aircraft to the front, and then to route all that power into a single gearbox. The best I can describe it is *'janky doesn't even scratch the surface'* Oh and I almost forgot, as stated in the video, the engine itself was mechanically unreliable and failed all the time. So yea.

It is my understanding that the need for the propeller was NOT for shorter take-offs but for improved thrust-response. The jet engines of the time had very sluggish throttle response. If a landing had to be aborted it took time for the engine to increase power. Hardly ideal for a touch-and-go on a short carrier deck. The same is true when trying to adjust for sudden changes in tail vs headwind on landing approaches. Contrast this to a propeller aircraft can which can adjust thrust on-the-fly simply by changing the blade-pitch. The engine can be left at high rpm in case power is suddenly needed. Even today, turbo-props deal with micro-bursts far better than jet-airliners and generally can set down better in fast-changing wind conditions.

I suspect that most aircraft, even today, cannot take off from a carrier without a catapult...

If you go up 20 decibels, the pressure is (10)^2 times the previous pressure, or 100x. This thing was said to produce 200 decibels.

Definitly not causing more torque on the aircraft 6. 14:19 this effect did not effect WW1 rotaries more. He's completely mixing up gyroscopic torque (of the prop or engine acting as a gyro) with regular coaxial torque/reaction torque 7. 14:54 completely useless statement saying it could roll to 30°. It can roll to any attitude if it's not counteracted, there is nothing stopping it at 30° 8. 15:05 BOTH ailerons are actuated, not just one. (only one is increasing in drag, causing the yaw.)

Advanced for it's time, but obsolete before it was finished because technology was moving so fast. I think the XB-70 Valkyrie falls in this category, too.

For many years, one of the aircraft shown in these clips sat on a display pylon at the entrance to Meadows Field airport in Bakersfield, CA. Meadows' history goes back to the days of hot air balloons in the 1890s. During WWII, it was improved by the Army Air Force so they could use it as a night-flying training field. In 1944, military operations were discontinued, and the field sat idle until the mid-1950s, when it reverted to civilian use. Somewhere along the way, one of the two XF-84H Thunderscreech aircraft ended up on that display pylon, with a small motor rotating the prop at a blessedly-silent several seconds per rotation. In 1992, the Air Force bastards took it back, leaving a nondescript T-38 trainer in its place (until 2015, when the T-38 was moved to Minter Field Air Museum in nearby Shafter).

Excellent video. I enjoyed the detailed explanation of why the Thunderscreech was what it was - noise and all - and why it didn't quite work as planned. No massive computing power to help design airplanes back then. Engineers did what they could with their slide rules, but the only way to find out for sure if a design was viable was to fly it. That plus massive Cold War defense budgets gave rise to some really strange and wonderful airplanes. The Thunderscreech was surely one of the strangest.

If there’s one post-war experimental plane I totally don’t expect to be covered by Real Engineering, it’s the Thunderscreech. Between this and the Tu-95’s massive contra-rotating turboprops that could reach supersonic speeds at the tips of the blades, it’s amazing that prop engines weren’t completely forgotten despite advancements in turbojet tech. Thanks for giving an insight for essentially a flying earrape meme. Edit: After finishing this video I now have a couple of questions. - I wonder if by making the props contra-rotate to each other would not only solve the torque issue, but also make the reduction gear smaller since it now has to drive two sets of props? It would also straighten the turbulent airflow and perhaps quieten it? - Also, how’s the heat management for the Thunderscreech? From my understanding, coupled engines typically ran hotter due to heat being trapped within the system. The He-177 “Greif” was notorious for having coupled DB-603 engines that would regularly caught on fire and further making the plane harder to operate.
@bricefleckenstein96663 жыл бұрын
Error on the timeline. The Tu-95 first flight was in 1952, the Thunderscreech came LATER - and the Tu-95 was IN PRODUCTION though not enough done yet to deploy them by the time the Thunderscreech achieved it's first test flight. The Tu-95 used contra-rotating props to cure the MASSIVE torque issue that engine would have caused - and to handle it's output.

@@bricefleckenstein9666 Updated. Turns out the turboprops on the Tu-95 were of German origin, and was a solution from Kuznetsov to combat the piss poor range delivered from 50’s turbojets on the Myasischev bombers. The props were so loud that even submarines in deep waters could track the plane from miles away with SONAR. Also, the same engines would also power the Tu-114, once the largest plane in the world and also still holds the record for being the fastest propeller-driven plane to this day with a top speed of 540mph. You made me learn a lot of stuff today. Thank you.

@@Nafeels I served on USS Ranger - we had at least 2 Tu-95 (probably marine variants) overflights during Westpac 1979, so I'm quite familiar with how loud the Bear can get. It's likely we had other overflights while I was asleep, as I worked mid-shift. The Tu-114 absolute speed record for a prop-driven plane was broken in 2003 by a current turboprop business plane (576 mph) but Guiness lists the Bear itself as the fastest production prop-driven plane at 606 mph. That is an estimate however, as the actual Bear never made an official speed record attempt - but given it's a lot smaller cross section than the Tu-114 with the same propulsion, it WOULD be a good bit faster. I suspect that 606 figure would have been from the MANY radar contacts the US Navy has had with Bears over the decades.

contra rotating propellers don't do much to quieten anything, the air from one prop smacking into the other is half of the reason why they are so loud. Having the tips go supersonic and basically giving a 'drone' of continuous sonic booms does the rest.

I'm no engineer, but I think some of these problems could be eliminated or greatly reduced by two solutions. 1. Counter rotating props. Two smaller propellers rotating on the same axis but in different directions. This would eliminate the torque problem, since the two props cancel each other out. And and by the use of two props their diameter could be decreased without decreasing blade area, lowering the prop tip speed. 2. Move the transmission behind the cockpit and have 1:1 gears in the propeller end. This would decrease the driveshaft rpm and reduce vibration.

Hey great video. One small point of disagreement. Your graph on efficiency of WW2 fixed pitch propeller, I pretty sure that graph would be for a variable pitch. That's a high efficiency over a very large speed range, whereas an actual fixed pitch propeller will work pretty well over about a 100kt range, far less than the Mach 0.7 your graph showed. Fixed pitch props are really only feasible on low HP and limited flight envelope aircraft. (I'm sure you are aware of all that though)
