Stuka Auto Pilot
« on: March 03, 2010, 04:54:19 PM »
I was on a few nights ago just goofing off in the Ju87 (Stuka).  I was practicing dive bombing in it (With the sound pack I have I am addicted to the siren noise when I dive in the stuka).  In one of my dives I could not pull out soon enough and of course crashed.  I had the dive brakes deployed but still picked up enough speed to not be able to pull out.  Which caused me to remember that historically the Stuka had an auto pilot that pulled it out of a dive at around 1500 ft or so and kept the plane from crashing if the G's caused the pilot to black out.  Is this feature replicated in the Stuka we have?  If so then I must have done something to cause it to not deploy (i.e. hit my controls or soemthing)?  If it is not replicated would it be possible to include in the game?  If it is modeled into the stuka then I assume I am startign my dive from to high of an altitude and can fix that by starting the dive at lower alt.  Anyways I was just curious and will continue to use the Stuka when the fancy hits me.

As far as I remember, the Askania system just trimmed the aircraft to recover from the dive. Considering we already have auto trim, it would be redundant.

Trying to break the sound barrier?  :P

Had to get up over 500 (IIRC) to break off my remaining gear after a red guy removed the first one.  Still had no problem pulling out at that speed.  Maybe you're just pulling back too hard.

Could be guys.  I was just wondering if it was me doing something or the lack of doing something in the dive.

Thanks

BigKev, what sound pack do you have that has a siren for the stuka? I've been looking for one forever!

Try pulling back on the stick and repeatedly tapping or holding the "K" key to help with high speed dive pull-outs. The "K" key is manual "up" trim for the elevators.

Make sure that you're trimmed properly, improper trim can negate the pull up effect of the dive flap.  Also, CT can also have a negative impact on it.

Try the new Ranger sound pack i think it has a good stuka file.

Just did some reading on Stuka dive bombing in Capt. Eric Brown's Wings of the Luftwaffe.  Interestingly enough, opening dive brakes were what began the dive.

Quote
The check list jfor preparing the Ju 87D to enter the dive was as follows:
Landing flaps at cruise position
Elevator trim at cruise position
Rudder trim at cruise position
Airscrew pitch set at cruise
Contact altimeter switched on
Contact altimeter set to release altitude
Supercharger set at automatic
Throttle pulled right back
Cooler flaps closed
Dive brakes opened
This last action made the aircraft nose over into the dive under the influence of the pull-out mechanism which was actuated by the opening of the dive brakes which also actuated the safety pilot control.

Quote
As speed built up, the nose of the Ju 87 was used as the aiming mark.  The elevators were moderatly light in the initial stages of the dive but they heavied up considerably as speed built up.  Any alterations of azimuth to keep the aiming mark on teh target could be made accurately by use of the ailerons.  These also heavied up as speed increased but always remained very effective. Use of elevator or rudder trimmers in a dive or pull-out was stricly forbidden.  During the dive it was necessary to watch the signal light on the contact altimeter, and when it came on, the knob on the control column was depressed to initiate the automatic pull-out at 6g, a 1,475-ft (450m) height margin being required to complete the maneuver.  The automatic pull-out mechanism had a high reputation for reliability, but in the event of failure the pull-out could be effected by judicious use of the elevator trimmer to override the safety pilot control.

The sequence of events on selecting the dive brakes was most interesting.  On extension of the brakes, red indicators protruded from each wing upper surface.  This action automatically brought into play the safety pilot control and the dive recovery mechanism.  The object of the latter was to return the elevator trimmer flaps to their normal position after release of the bomb, thus initiating pull-out from the dive which had been started by the elevator trim being brought into action to nose the aircraft over.  The safety pilot control was a restriction introduced into the control column movement whereby this was limited by means of hydraulic pressure to a pull of only 5 deg from the neutral position, thus obviating excessive g loads in pulling-out.  In an emergency this restriction could be overridden to give a 13 deg movement. Once the aircraft had its nose safely pointed above the horizon from the pull-out, the dive brakes were retracted, the airscrew pitch set to takeoff/climb ant the throttle opened up to 1.15 atas of boost, although in condidtons of enemy flak it was recommended that the full 1.35 atas be used.  The radiator flaps were then opened.
