  1. "Soundtrack" to a fictional "plane crash" movie.
  2. Two more sources: -Report (P-38J, 1944) -From book "Americas hundred thousand":
  3. @KW_1979 Ok. I am not going to agree or deny now that control should be "easier". I need to collect all the materials again and think about this problem. Perhaps during work on the future P-51. I think at least the efficiency of the trims should be tweaked. Perhaps this problem too. But I cannot promise that something will be changed, I will repeat - it will be necessary to evaluate all the data again. Perhaps several problems were mixed in this topic - an increase in stick force, a loss of control due to the M number, as well as differences in aircraft with and without a "bobweight". Yes. Of course "they" don't care. It doesn't matter that they answer on the forum, they make corrections, as with the gear bay drag recently. Obviously "they" don't care.
  4. Sorry, but you are wrong. First, there is no "magic mach number" ingame, after that airpalne become "unrecoverable". And at M = 0.75, effects of compressibility begin to be noticeable, and with an increase in M they intensify. But this does not mean that after 0.75 the plane cannot be recover from dive, because this is limit and what the manual says. Further. I checked right now. I tried to recover from steep dive (dive angles 50 ... 80) at mach numbers 0.8, 0.82, 0.84 (altitudes and indicated speeds, respectively ([m] / [kph]) - 3600 / 780, 5900 / 690, 5700 / 715). Fuel - 50%, trim in neutral, throttle closed. In all cases, the aircraft exits from dive with a loss of altitude of about 2-3 kilometers. It should be noted that the loss of altitude is less than what is written in the manual. This is by the way that the leadership is "taken literally." And finally, I hope that in the future the model of the influence of compressibility on the controllability of the aircraft will be fine-tuned.
  5. I accept the argument that the gear door locks should have been fixed in the regiments. At D-15, I think this really should not have been, I will correct it.
  6. Firstly, when you diving at high speed, you should not forget about the effect of compressibility. In this case, it is not speed that matters, but the Mach number. On the left side of cockpit there is a plackard with a speed limit depending on the height. You say that the 485 mph plane is poorly controlled. So, but above 5000 feet it is forbidden speed. One of the effects of compressibility is a drop of aerodynamic control surfaces efficiency. That is why they write that it is useless to use a trimmer - with a large M number, the elevator or aileron itself loses effectiveness. Further. Suppose we have a speed of 485 miles per hour near the ground. At the same time, when 50% of fuel, we can make about 4g, and this is a lot, considering the speed, and the fact that there is no getting away from the “stiffing” of the control - for example, in the same dive report it is stated that the stick force is “relatively” light in dive. And if you reset the trimmer to neutral, it will be 5g near ground at 485 mph. And at 400 miles per hour, we have 8g on the ground level with a trimmer in neutral, and we can get even more if we help with a trimmer - 10+ g. And 400 miles per hour is also pretty much speed... And finally. It should be noted that in the 44th year there was a modification of the control system. A "bobweight" was mounted on the stick. Without its installation, indeed the stick was too light, and at the same time there was a danger of easily exceeding the overload restrictions.
  7. Thank you, friends! To see that people like the result of our work is very great!
  8. Modelsvit Tu-91, 1/72. Work in progress, rebuilding cockpit:
  9. Dive brakes and trimmers on the right side of elevator linked by hydraulic line, an there is no valves in this hydraulic line. And electrical part of dive system - electromagnet and spring in the trimmer control - "blocked" with the bomb drop system, and can be turned off only with it. Do you have any document, mentioned that dive system is can be turned off some kind?
  10. You can not turn off dive system at Ju-87. Control key (LCtrl+D by default) used at Ju-88 and Pe-2. And contact altimeter is not connected with dive system, it is used only for sound warning.
  11. In game you can dive either with and without dive brakes. If you dive without dive brakes, you can engage dive system by press LCtrl+D (same key for recover).
