When I google searched it there's a link on Yahoo answers that says because their APU generators aren't strong enough and their aircrafts' airconditioners draw too much power from the engines. Is that why Russian/Soviet aircraft need to have a fan in the cockpit?
Besides those fans don't have covers around their blades! Doesn't that pose a threat to the flight crew?

Yeah, and also why are their cockpit panels always painted turquoise, AND why do all Russian aircraft from fighters to transports have their wheel hubs painted olive drab green? I think we should be told!

We had those fans on L410 and they were sufficient and caused less clogged noses and soar throats than air conditioning with apu on other types.
Blades are made of rubber, you can easily stop them even with a finger.
I seriously think I just creamed my pants without any influence from any outside variables.

Quoting s5daw (Reply 1): I have seen a fan in an Antonov An2, but modern jets, really?

They Russians believed it reduced fatigue & kept the crew Alert

I think it has more to do whether the cockpit was equipped with gasper vents or not. In the pictures with fans, I didn't see any gasper vents but I saw them in photos of the more modern planes without fans.
Quoting Ptrjong (Reply 7): I guess it never occurred to the topic starter it might simply be a good idea.
The OP never said it was a bad idea. He is just asking a question.

Thank you. Yes, I was just asking a question.
And thanks for all the input too. I just thought it's ironic that while the massive jet engines' fan blades are pushing the aircraft forward, there are tiny lil fans that's blowing at almost the opposite direction in the flight deck.

That is an interesting trade.
The fan is a simple installation that only require electricity as opposed to ducting and stuff in a gasper air.
How are the equipment in the cockpit cooled? Draw through or blow-by? If it's draw through then the gasper air would require a separate ducting system.
Of course, with the fans you may have higher failure rate/maintenance issue depending or how reliable those fans are . . . but I guess you can still dispatch if one of those fail

So if you put in on the conveyor belt, and have the fans blowing over the pigeons in the back, you won't take off?

On the KC-135 we have at least 5 fans on the flight deck. They all have cages around them of course! There is no air conditioning system for use on the ground so they're a requirement for a warm day. You want pictures?

Well, wouldn't they be blowing the same direction as the big fans on the wings?
In this case they will of course be providing additional thrust, which is necessary for some of the under-powered Russian aircraft. Obviously 5 fans are required for a fully loaded KC-135, because it's heavier.
They are usually the type that can rotate at least 180 degrees, so you often see the pilots quickly turn them in the opposite direction upon landing, especially if the engines do not have thrust reversers.
Basic stuff really.
