Throttle mechanics "linear" (rail)

[GVL224]

Hello.
I present to you the new mechanics for the throttle.
The peculiarity is that the movement of the handle is straightforward.
This option has a 150mm stroke.
This indicator can be both reduced and increased using shafts of appropriate length.
The length of the required shafts is "handle stroke" + 100mm.

Very nice! Is this sort of thing meant for those with large home cockpits?

This is for those who do not like to bend the brush.
And some real aircraft have such a handle movement.
And it’s possible to do less and less length, I think that it’s optimal about 10 cm, but here it’s 15 cm, one person wrote that he wants to generally move 20 cm.

Mig-29 style - need iddle/afterburner detent.

How about this option to not to bend the wrist?

This is real, on my old mechanics there’s a boost.

It seems to me that the only "plus" of such mechanics is the volume occupied in the throttle body relative to the "linear", but more than my classic.
And the fact that the height changes is a minus.
Also, to exclude backlash on the axes, and they are obtained FOUR, you need to use bearings that will increase the mass and dimensions of both the lower and upper parts.
I do not like this option ...

Ah yes, I forgot about such examples like the MiG-29.  

 

Trying to think: did any WWII planes have such a throttle?

@GVL224, I also wanted to ask you: any possibility to design a latch that would connect the throttle lever with an adjacent lever? This was a feature, for example, of the P-47 - it allowed the pilot to move the throttle, rpm, and turbo levers at the same time, instead of having to move each individually.

Unfortunately, I still can’t make such a latch.
everything is very tiny and fragile, a reliable connection does not work, if you move one handle, then the second is slightly behind ...
Personally, I’m used to moving these levers with one hand at the same time, holding them with one hand if necessary, for this I originally made my arms as in this video.

Understood, thanks.

 

Speaking of throttle handles: are you interested in adding to your list of available handle designs? For instance, I have downloaded the original drawings for a number of P-47 throttle handles and can post them here if you would like.

Yes, of course, show it will be interesting.

Ok, this is the stuff I have on the P-47 and the P-51:

AFAIK - None, this kind of throttle is "modern".

Pardon @Sokol1, this is very interesting. I believed the FW 190 had such a throttle, but I am not sure of that. I could only tell from pictures, I've never held a real one. It looks like it, but do you have any information on that?

Hmm, don't think so. The FW 190 had no such throttle systems. If you look at the left console just a little below on the side wall, you will see that turning knob which allows

the pilot to set or change the friction strength of the throttle lever. So no.

No, Fw 190 "gashebel" has pivoting lever like most - if not all, other planes of era. 

 

Because in 190 the most part of lever is enclosed in the lateral "console", you have impression that move linearly.

 

 

I guess that the spring and lever in lower part, next to the pivot is the tactile "detent" before engage "Kurz-Leistung"  ~ "momentary performance"  (WEP).

Drawings and pictures (of reproduction) are for latter versions 190-D when the throttle are  somewhat simplified for speed up production.

Early versions are more "elegant", with the upper part of lever curved back, and inclination in the grip leaving more ergonomic for pilot hand.

In this "relic" the lower part of lever is broken.

Thank you, very interesting! Man,  so many production steps just in the lever. And material as well... 

 

...no wonder the Russians / Allies won. Production numbers. Reflects. Just compare even the pedals (Einheitspedale vs padded metal bar)..

 

Cool insight, thanks for the thorough information.

no, these potentiometers are small and will start to make noise over time.

And they are rubbish. They simply dont work for long life

Rail mechanics with a rod locking mechanism in any pre-selected travel position.

On one mechanic, you can use several racks of limiters.
