    Little correction/precision to what I said at 04:56 - it is of course 'Down / or more accurate: Neutral position', not Up. I misspoke and didn't catch it in the edit, rather annoyed by this. Thanks go to charles and Brandano for pointing it out. (I had already pinned comment just like this one but it seems to have gotten lost - if someone finds it, return to sender!)

      Don't feel bad, it's an easy mistake to make, even for professionals. There have been cases of mechanics rigging the trim tab backwards with fatal consequences, at least one of which we know of for certain during the past 2 years (a twin).
      Excellent presentation! The Stuka was a far more technically advanced aircraft than most people realize - deutsche Technolgie!

    My grandfather was a tail gunner in a Stuka in North Africa. He was captured by the British and put in a POW camp. He and another guy beat the guard assigned to them to death with a shovel and took off across the desert. He then hitched a ride on a civilian boat to southern Italy just in time to get captured by the British again. He learned to cook and speak Italian in that 2nd POW camp. He was part of a prisoner swap late in the war and spent a few months as a crew member on a Heinkel HE-111 until the war ended. I never had the nerve to ask him who actually killed the guard. It wasn't something that he talked much about until the end of his life. I have a DVD of him talking about his war experience to a college class. I have a picture of him in his Luftwaffe uniform when he taken when he was in his late 80's. It still fit.

    Just a little comment about the "size of the target presentation speculation": If you want to hit an aircraft with AA guns, the best moments are when the aircraft is not turning. Neither horizontaly nor vertically. -> when it's going in a straight line, no matter the direction is best.
    Reason being: with AA guns you have to hold over so the plane and projectiles "meet". And with distance and speed of aircrafts the holdover is substantial. (Looks very weird if you see that the first time in real life) With an aircraft turning, the holdover is changing during the turn and no sighting system can counter that. (Or could in WW2 and even until the turn of teh last century i would say.)
    Long ago i got trained on a 3.5cm twin AA gun system. It uses weather information (wind, temp and air pressure) as well as projectile speed, laser ranging ect. and can be radar guided, uses explosive shells, fires around 1100 rounds per minute...So it is far superior to any WW2 AA gun. And still, a turning aircraft is almost impossible to properly hit.
    (We are talking about the same system that shot down RAF Sea Harriers in 82')
    When it aims for you, that is (according to my training) your best chance to hit a hostile aircraft. The aircraft has to maintain it's direction for at least a few seconds to get a proper aim, and that's the amount of time you get. (So, you get a max of a few seconds and the smallest target size the aircraft can be, but at least you don't need a holdover)
    Basically its like the "game" the germans call "Schisshase", where two cars drive towards each other until one of them gets scared and turns away. Only that here it's about who manages to first score the hit.
    One of our officers once said AAA is 23 hours and 59 minutes of extreme boredom and 1 minute of hell on earth.
    The other chance would be if it hasn't noticed you and is in "level flight" crossing your field of fire. But let's be real, that is less likely to happen.
    Yes, AAA sounds a bit suicidal (especialy considering modern weaponry). Let me just say that in my defense, most of these things i did not know (or consider) when i ticked the AAA box on the form i was given to mark on which weapon school i would want to transfer to.
    (Actually after 4 intense months of infantery training, the idea of getting transported by a truck instead of walking everywhere with up to 36kg of gear on the back was very intriguing. As was having probably a sitting job, not having to "walk, crawl, glide... into position". And as a military aircraft enthusiast i had good expectations to not need any training in identifying aircraft siluettes...
    And should i mention that i didn't pass the second stage of the "military pilot selection process" shortly prior? 🤫 )
    An to end my comment, something else that could be thought provoking: We were told to not waste ammo on leaving aircraft.
    (If it has "unloaded" already and there are targets available that have not yet, they are more important to get shot at.)

    • @BeingFireRetardant
      @BeingFireRetardant 2 года назад +11

      Well stated. 1100 35mm shells travelling 3000fps in one hairy minute is a lot of BBBRRRrrrrtttttt...
      And even then, target acquisition is tricky and momentary.
      That part alone is identical to WW2 gunnery struggles. That's how the kamikaze got through. Because making a firing solution on a diving aircraft is nearly impossible, in that making hits, or even a kill, does not negate mass x velocity physics...

The stage i didn't pass, is where (according to the head psychologist who ran this test stage) 98% of candidates at that level didn't make it. (Our airforce was/is small enough that they can be that picky) From what i learned later, i would have been dropped in the next (last) stage of medical checks anyway. One of my comrades made it to that stage and got dropped for having a light pollen allergy. I am "blessed" with that too.

    I am fairly sure that trim tabs of that style will actually work like servo tabs, deflecting in the opposite direction of the elevator. To trim the elevator up they will deflect slightly down, lightening the control force on the elevator itself. At diving speeds they can be quite effective.

    Another important design reason for the Sicherheitssteuereung is that it prevents a possible stall, when recovering from a dive. Aerodynamically it makes no difference if you stall an aircraft in a steep climb, or when pulling up from a steep dive: it's all about the relative wind and the Alpha angle.

    My uncle, who was in the karelian isthmus frontlines during summer of 1944, said that it was a sight to behold when Kuhlmey's stukas hit soviet positions, often 15-20 planes strong. He also said that the pilots were really professional and usually hit their intended targets, wich were mostly staging areas for tanks etc. Said that they often heard tank engines roaring and when stukas paid a visit, it was total silence, only black smoke from where the tanks were.

    The father of a school friend was a flight engineer in the Luftwaffe and he told me of the only time he had been in a Stuka. One had just been returned from maintenance and had to be test flown and his friend (a pilot) offered him a ride. They climbed, did some manoeuvres then his friend said "Hey Kurt! Hang on!" and then went into the dive. He said all he could see was blue unless he looked over his shoulder and then all he could see was green! Then.... they pulled out. He said all he could see was green and his lunch was about to impact on the cabin floor, walls and canopy. He never flew in a Stuka again.

    I had learned that Italian pilots using Stukas learned independently to conduct skip bombing. This is dropping a bomb at a certain speed and near horizontal angle that will skip like a stone over the water. It will hopefully strike a vessel near the water line. US pilots used this technique as well in the Pacific.

    It is my understanding that some JU87 aircraft were fitted with either a belly camera, a tail camera or even both. The usual belly camera was a Leica 250-GG "Reporter" camera taking up to 250 24 x 36mm images on a 10m film strip of standard 35mm perforated film (I have one of the earlier but very similar Leica 250-FF Reporter cameras) and with an electric motor drive. The tail camera when fitted, was a smaller and lighter Berning Robot camera, also using an electric motor drive, rather than the clockwork motor drive of the regular Robot cameras. These take 24 x 24mm images but I have not been able to ascertain the length of film in this special version of the camera. The idea was for the belly camera to assess bombing accuracy and the tail camera to assess bombing effectiveness. I have been told the Leica was switched on manually but the Robot automatically, perhaps when the pull out device, which causes the jolt, is activated. Anyone got any more information on this subject?

    4.52 Are you *sure* Chris?
    IF you deflect the trim tabs UP that would typically cause the elevators to deflect down, the nose will thenpitch down & the dive will steepen won't it?
    At circa 7min you're talking about why have a sicherhaitssteurung (now there's a word to drop into converstaion at the arifield).
    Everything you say makes sense but there's a further effect interwoven with all of it which may be another major reason to fit that system.
    If the pilot's groggy with high G on pullout maybe there will be a tendency to pull back too hard (as you say). Then, beyond stressing the airframe, there's a pretty high risk of a high speed stall too.
    And that would see the JU87 go boofing into the ground like a kayak pancaking off a drop onto water hitting flat with the underside belly.
    In other wods, the nose is horizontal, even pointing upward but momentum is taking the aeroplane down, because high angle of attack means the arirflow over the wings is a turbulent mess of a high speed stall with virtually no lift.
    (Tried to find an addy to send this to you direct Chris but can't see one)

  • @kaiwortmann6852
    @kaiwortmann6852 2 года назад

    Very nice video about dive recovery system of the Ju 87. Everybody knows it, but nobody knows how it really works. Thanks for that. I may add my humble suggestion concerning the removal of the Sicherheitssteuerung from the Ju 87 D-5 onward. The Ju 87 D-5 was delivered from the Summer of 1943 onward to the Stukageschwader. At that time tactical changes within the Ground Attack Arm (Schlachtflieger) of the Luftwaffe took place, gradually pushing the Ju 87 into to the role of a ground-attack aircraft (Schlachtflugzeug), instead of the role of a dedicated divebomber (Sturzkampfbomber). This change of role lead to a different attack mode of the Ju 87, emphasising the close air support role instead of the divebomber role. Simply put: Divebombing became less important, especially in steep dives. Maybe attacking by pushing over the wing into a dive, instead of pushing over the nose can be a factor, too. I think the revised armament and armor of the Ju 87 D-5 reflects this changes: switching from 2x MG17 to 2x MG151/20 and more armor for the pilot and engine. One further point may be the simplification of the production of the Ju 87, to get more produced: Entfeinern was the order of the day (for a description of this process see Lutz Budraß, Flugzeugindustrie und Luftrüstung in Deutschland 1918 - 1945). It would be interesting to know if other late war versions (D-7 and D-8 night ground attacker) had the Sicherheitsteuerung also removed, i would bet at least for the D-8, as this version is based on the D-5. Last but not least, it would be interesting to know if divebombers of other nations did employ a similar (or perhaps completly different) dive recovery system as the Ju 87.

    Hi Chris! Greetings from the USA.
    It's funny about the word Sicherheitssteuerung. When I saw the word on screen I thought literally "safety control" or "safety steering," which of course is not close to the very clear translation you made. You say that you made 4 words out of 1. In English, we think precisely the opposite; that Germans make one word out of many. My favorite is "Hanschuh." I look at it and see "hand shoe." A native German speaker probably just sees the one word for glove. I will never learn to speak German properly!
    Anyway... new subscriber here. Very interesting content.

    Excellent! I had no idea of the Abfangvorrichtung.
    One point and one question:
    Point: I can think of no tactical reason to change the initiator of the Abfangvorrichtung. I would not be surprised if it were the results of an economic decision. Possibly the automatic Auslöser simply cost much more than a simple electric switch on the control stick.
    Question: How long did the Abfangvorrichtung remain activated and how was it disengaged? I imagine they would design it to at least remain engaged until the AoA was above the horizon. But if the pilot was really blacked-out for so long, and the AbVoRi didn't also automatically disconsciousness
