    I liked this instructional video.
    My Father while in the Army designed and tested missiles at White Sands base. My sister has all of his written calculations/descriptions/designs. I like watching him putz with a small bicycle tire having welded rods on the center of the spoke array so he can hold onto it when he got the electric grinder/tool sharpener going at around 3400 rpm and placed the tire to it and got the tire spinning so fast he could hardly handle the dynamics of the spinning wheel in his hands. I watched him make his observations as he tried/forced to tilt the wheel in any direction. he was my teacher and inspiration for inventing. For a winter project we built a gyro copter,aluminum frame and a wooden 3 ply rotor/no motor required. springtime came along and he took it out of the barn and with a strong nylon rope attached it to the copter and the other end tied it to a stake in the ground. being 8 years old at the time, I sat in the chair of the copter..the wind started to pick up and the rotor(not knowing of the rotor brake)began to rotate faster and faster. I did not want to jump off it fearing the blade would kill me..so I went airborne and the first to fly it(sort of). I screamed for dad and he ran out of the house. being about 15 ft in the air he could only give me instructions. I got hold of the steering column, he said push forward slowly ..I did and landed perfectly,he jumped on and knew how to brake the rotors speed. Man what a ride,.he smiled at me and said " I really wanted to be the first and only person to fly it,.but now you have that honor" he was not mad,.but all the more determined to test fly it for himself. Obviously my weight was less and why i went airborne. A week later he and a few friends took it to a large prairie. they attached a long tow rope from copter to truck, dad put on a cheap helmet and harnessed himself in the seat and gave the order to go. the truck traveled about a quarter mile and dad released the guide rope..straight up he went,.then down,.then sideways,.then stabilized his flight. airborne for the better of twenty minutes flying around i could see a grin so big on his face looking though my boy scout binoculars. he eyed a long empty stretch of country road and began his decent and made a perfect landing. When it was all over his friends nicknamed him Gyro Jack. and ya know..he never flew anything else before and the only knowledge of flying the copter came from reading over and over the flying instructions and what to expect and how to counter any problems. he was a cool dad, I am proud of him . Sorry I just had to tell a story here. hope you had fun reading it.

    I used to work at a place that made gyros , part of the calibration procedure was to let them run for a week . This was called caging the gyro . You could watch several gyros spinning when I arrived at work the gyros would be flat perfectly . When I left work they all were about180 degrees pointing straight up . The gyros had NOT moved it was the earth that moved . Blew me away when I saw it happen .

      Good point here. Maybe somebody can explain how you can steer with gyro control without the earths curvature and rotation screwing you up ?

    • @robertlong2531
      @robertlong2531 5 лет назад +9

      Just done a bit of googling, think I can answer my own Q. with a crude solution. Earth rotation compensation - earth rotates 15 deg./hr anti clockwise, therefore if say time of flight 1 hour, simply aim rocket up to 15 deg to left of target (if target is due south). Earth curvature compensation - correct gyro with an air pressure reading altimeter.

    This is the first time I've seen a demonstration of the concept of active control using the broom, that I recall. Perhaps it was the way you succinctly made the the mechanics crystal clear. Absolutely nailed it.

    Excellent presentation. And thank you for not flooding the video with rock music, techno music or multiple frame snap- backs or constant close ups of you ( not dismissing you, but many RUclips presenters are trying to promote their personal image rather than present the information ). Your presentation brilliant for showing it is a gyro in a gimbal with instrumentation on the gimbal providing the guidance data - that is what many explanations skip (or don't know or can't explain). Thank you. I have spent many hours watching your videos on rockets. Now on to your astronomy vids . . .

    Worked in Marine navigation and used to rebuild spinning mass Gyrocompass's by full overhaul , cleaning , dynamic balancing the rotor and then reassembly with new parts ,balancing the gyro itself then running it up and while it precessed and stabilized , checked it over 4 hrs of runup , adding weights as required ... then afterwards test runup and check of the Gyrosphere balances by using a swing table , interesting work .

      Hi there. That's right, Ford's German subsidiary Ford-Werke made various contributions to Germany's war effort, trucks, as you say, and parts of the V2 rocket. We need to remember that after 1939 and the outbreak of hostilities, the company was only related to Ford by name - the American HQ had no say in the company's direction. Ford-Werke also used slave labour even before the USA entered the war. Using enslaved people was a commercial decision and was not forced on them by the Nazi government. Thanks for posting.

  • @stefanrichter9162
    @stefanrichter9162 5 лет назад +3

    I read the book from Walter Dornberger (he was the director in Peenemünde) about the engineering struggles of the V2. He told that the giroscopic correction system was to slow in its reactions to mantain the correct orientation of the A4 during liftoff. So they designed an inertial movement detector , aka an accelerometer in two directions , to steer the rocket during liftoff. An accelerometer reacts in the same moment when the orientation change starts , where the giroscopes react when the when the orientation has already changed.

      I worked for 23 years at a steel mill. In the 1970's I was helping a guy with a heavy German accent move boxes. He was in charge of the office storeroom. At lunch break, he saw I was reading a science fiction paperback and asked if I would like to read a book about the V2 rocket. Of course I said yes. It was Dornberger's book. It was inscribed by Dornberger to the office supply manager. Apparently they were friends. If I recall, the manager's name was Otto Heinz Kuhn.

      @vitaliytsupruk2047 7 лет назад

      can you please explain this? It seems like the curvature of the Earth would cause the gyro to be inaccurate.

    • @As_A________Commenter
      @As_A________Commenter 2 года назад

      @@vitaliytsupruk2047 The curvature of the earth does not affect the accuracy of the gyro, because wherever the airplane is, it is essentially at the “top” of the world. The attitude (orientation) of the airplane is always relative to it’s exact position. This is why the gyro is even more important at higher altitudes, because the artificial horizon it displays is more accurate than the actual horizon, which is skewed by the curvature of the earth.
      Altitude is maintained by seeking a constant air pressure, so even as an airplane travels across the globe, it’s attitude orientation remains constant, and the altitude is adjusted by maintaining a height at a constant air pressure.

  • @deezynar

    That's a very good question. I'd guess it had a timer between the gyroscopes & the control surfaces that had preset control angles that it implemented at the correct time in the flight. Otherwise the gyros would either guide the rocket continuously straight up, or start it turning before it cleared the launch equipment.

    Hi, Reduce the friction of the bearings. Improve the rotor by making it heavier and making sure it's very well balanced. But the best/simplest way with a toy gyroscope is to wind the cord carefully onto the spindle so that each turn of cord is neatly on the spindle - and when it's covered, run the rest of the cord neatly back on top of first layer and so on. Basically, avoid allowing the cord to simply wind onto itself. This way the pull will impart maximum RPM for any given pull force. KR RJD

    I noticed this little fault too, it's actually called the 'Pendulum rocket fallacy'. On the pyro rockets it's just the aerodynamic drag effect reducing the instability (not negating it entirely) sending it into a gravity turn trajectory. Maybe it's just the term 'counterbalancing' that is not correct and causing the confusion (and introducing the pendulum fallacy). Nice video though, love seeing the actual original rocket parts.

    In the video he makes a gimbal for a toy gyroscope. He uses a cool metal strip from a roll that has regularly spaced hole so he can use screws and bolts to assemble it.
    He shows gyros from a V2 and from a "Soviet era SA75" surface to air missile.
    There's some V2 launch footage including one where the rocket engine is making just enough thrust to keep it suspended above the launch site.

    A professor of mine told a story about a science teachers' meeting. One participant had prepared a suitcase with gyro inside. Arriving at the conference hotel, he spun up the gyro, signed in and the let the bell boy help him with the suitcase. Coming to the corridor corner, the bell boy was amazed how the suit case did not want to make the 90 degree turn. Well, after this story the professor lifted a box from behind the stand, grabbed a string handle and pulled it heavily. Then he demonstrated with that box how the mentioned suitcase had behaved at the hotel. I believe everybody in the audience enjoyed this kind of teaching as much as I did.

    @notmenotme614 2 года назад +1

    As the rocket moves around, pitching rolling and yawing. The gimbals always rotate themselves to keep the spinning gyro aligned or pointing to the same spot in 3D space. Imagine the gyro stays perfectly still and the rest of the rocket is rotating around the gyro, with the gimbals as the pivots.
    As the gyro stays still, the potentiometers measure how much the gimbals have deflected as the rocket pitches, rolls and yaws. There for the electronics know the rocket has moved -2 degrees in pitch and sends a signal to the vanes to move +2 degrees in pitch, until it’s back to 0 degrees.
