doright Posted August 24, 2014 Share Posted August 24, 2014 (edited) Total pitch angle of the stick is 20 ° ,and 15° in the roll axis ... Deadman have you any way to tell stick travel from control surface neutral position for real A10? Roll is probably symmetric but likely there is considerably more aft stick travel then forward starting from a neutral stick position.

Dropship Pilot Posted August 24, 2014 Share Posted August 24, 2014 (edited) Hans, the label of the Sensotec transducer says: Model A281-02 RANGE 0 TO 1000 LBS EXC +/- 12 VDC OUTPUT +/-10 VDC So, I'm quite sure these are force sensors to determine the forces acting on the stick. Similar models are still in production (see page 79 or LO-5 of this document: http://www.fedtec.com.tw/files/sensortec2006_catalog.pdf ). 1000 lbs seems overkill at first sight. However, if you consider the lever ratio of the stick you'll get about a 10:1 reduction of the force at the end of the stick. A 100lbs maximum stick force sounds plausible (to simulate a blocked linkage for example). The position of the stick is determined by the resolver that is mounted onto the torque motor. Not the most direct way to do this, but there shouldn't be much backlash in the linkage system (or the A-10 wouldn't fly ;o).

Deadman Posted August 24, 2014 Author Share Posted August 24, 2014 (edited) DSP thanks for your thoughts I did misspeak on what i was planing on using the 21BRCX-500-H7A brush less resolvers are planed on being used the pdf with them is attached to post 548 http://forums.eagle.ru/showpost.php?p=1916386&postcount=548 I have picked up a power supply for the pitch and roll motors but nothing has been connected yet. Once the credit card is payed off I can get a new computer and some control cards and wiring will start Edited September 7, 2014 by Deadman https://www.shapeways.com/shops/a-10c-warthog-supplies https://forum.dcs.world/topic/133818-deadmans-cockpit-base-plans/#comment-133824 CNCs and Laser engravers are great but they can't do squat with out a precise set of plans.

agrasyuk Posted August 25, 2014 Share Posted August 25, 2014 possibly but I am not sure why you need that information.The drawings I have made all ready have the base mount for the stick modified to mount a TM warthog stick base in to.

Deadman Posted August 25, 2014 Author Share Posted August 25, 2014 My trainer will still use its real stick and the rod connectors to the torque motors. Because you guys can not afford the parts in my trainer many are not available to the public at a reasonable cost. I am modifying the plans for a build that does not require a CNC or any high dollar components.One of the main modification is to the stick mount so it holds a warthog stick base. Builders then can add stick extensions and any springs to give them a realistic hight and feal to the stick. I have had severil form member over to the house and they all have said that sitting in the pit is totally different than what they have at home with their pits. these plans will be for the hard core builder that wants to build the pit once and not rebuild year after year. https://www.shapeways.com/shops/a-10c-warthog-supplies https://forum.dcs.world/topic/133818-deadmans-cockpit-base-plans/#comment-133824 CNCs and Laser engravers are great but they can't do squat with out a precise set of plans.

I'm not limiting myself to the Warthog it still may be workable though. I just find equal forward and aft stick throws unrealistic. But more importantly since it reduces the aft travel it has the effect of reducing sensitivity of stick movement. Why use up half your angular resolution on a range of motion you rarely use?

Deadman Posted August 26, 2014 Author Share Posted August 26, 2014 (edited) Hi I think you have misunderstood my post. I only gave the total travel of the pitch 20 degrees and the total of the roll at 15 degrees . I never stated the pitch throw was equal off of center or neutral position witch it is not. So your point is well taken but unnecessary. Total pitch angle of the stick is 20 ° ,and 15° in the roll axis measurements were taken off of the stick shaker as it is a cylinder on the stick providing a constant surface on both axis of movement.

So your point is well taken but unnecessary. Sorry, sometimes I forget that the multiplicity of topics in a thread can make it hard on a OP to know which topic your referencing. I should have quoted my original question: Deadman have you any way to tell stick travel from control surface neutral position for real A10? Roll is probably symmetric but likely there is considerably more aft stick travel then forward starting from a neutral stick position. Just out of curiosity I looked up the rigging (erection) manual on the P51. Process was roughly put elevator in neutral position, tension cables, move stick so top is 2 inch from instrument panel, set fwd stop, adjust linkage so elevator is 20deg down, move elevator up to 30deg, set aft stop. So neutral and aft stick displacements are just what you end up with to get desired elevator travel, no set in stone figure. Not to say, however, that there isn't some calculated positions shown on engineering drawings. (edit) More interesting info. On P38 control column neutral was 5.75deg fwd of vertical. Fwd movement 9.25deg, aft 24.75 deg from neutral. Aileron control was a whopping 144deg left and 144deg right on the wheel. Wonder what the process is on the A10?

Deadman Posted August 26, 2014 Author Share Posted August 26, 2014 So then your asking me to measure the angle of of forward and aft movement of the stick from an estimated neutral position. there are no control surfaces to actually tell when the stick is in that neutral position. If I understand I still don't understand the importance of the information. https://www.shapeways.com/shops/a-10c-warthog-supplies https://forum.dcs.world/topic/133818-deadmans-cockpit-base-plans/#comment-133824 CNCs and Laser engravers are great but they can't do squat with out a precise set of plans.

If I understand I still don't understand the importance of the information. Yep, that's it exactly. (edit) Well kind of exactly, there maybe rig pin holes in the system that will tell you neutral. Not extremely important, I was just contemplating a home brewed floor mounted control system, sensor and USB micro-controller. Meaning I'm not limited by what joysticks manufacturers do (but am limited by Windows DirectInput and USB HID requirements). I just realized my phone has an inclinometer on it, so maybe next airshow I'll pay some pretty girl to distract the pilot while I lean in and take some quick measurements.

Deadman Posted September 8, 2014 Author Share Posted September 8, 2014 (edited) For the switch it is a potentiometer with an off positions that has an audible click when turning it in to the on and dimming position. I don't have the model number with me at work. As far as wiring it would depend on the type of IO cards you have. But it would appear that you would wire the on off switch part to a switch connection on a card and the potentiometer to the appropriate section for it depending on the card.

Hempstead Posted September 9, 2014 Share Posted September 9, 2014 Here's how the original's Flood light works see the picture, you can do the same, similar to DM says for the Flood light. The original flood light electronic is a variable AC transformer with a off position built in but that's irrelevant to us. In the picture, from the left to the right. 1. Pot (made in Mexico. ;-), 2. a aluminum disk with a drilled hole and a pin to create the click at "off" position (no electronics here). 3. an aluminum disk with a flat notch and a microswitch to trigger the off signal, 4. another aluminum disk with a flat notch and a microswitch to trigger the T Storm signal.
