Bf 109 Slats?

[83_Gen_Jeroen]

21. Fixed abrupt blackouts that pilots of Bf 109 experienced when using flaps while the slats are out;

 

 

That was in the diary today.

 

Did not even know the Bf had slats.

 

Is that like Leading Edge Flaps?

 

Can they be set in controls?

 

Hope someone knows.

Leading edge flaps.

 

Automatic/operated by air pressure or magic or something so no controls.

Slat is a small extention of the outer part of the leading edge used in some fighter designs in the '30s and '40s to enhance low speed handling and agility and make stall characteristics more gentle. They can either be fixed in place (which is usually only used as a stop-gap solution as it severely affects performance at higher speeds) or be automatically deployable (meaning they are spring loaded to extend themselves automatically at a critical angle of attack) Under normal flying conditions automatic slats (which are found on the 109s and the La-5 in BoS) are retracted and form a normal part of the leading edge of the wing. If the airflow over the wing reaches a critical angle of attack, the slats will deploy allowing the wing to continue generating lift at a point, where it would normally be stalled. Ideally the slats will deploy simulatneous for both wings, but in certain situations one slat can deploy without the other doing so, which is dangerous, since the two wings now have markedly different stall characteristics, meaning a spin is almost certain if one wing stalls. 

 

Note, that the slats do not deploy at certain air speeds but are controlled by angle of attack. It's perfectly posible to get the slats to deploy at well over the designated stall speed of the aircraft.

Thx for reply.

Thx for reply.

Most modern airliners use slats for the same purpose, as well as STOL aircraft like the Storch and Zenith 701

The Bf109 was designed with small wings which allowed it to reach very high speeds but just by themselves would not have been ble to achieve good manouverability and would have been dangerously unstable on landing.

Slats keep the laminar flow over the wing even at very high angles of attack, basically don't allow the wing to stall.

This means that the Bf109  is, despite the small wings, a very good turner, since it doesn't really stall in turns. This also meanst that it shows no tendency to flat spin.

I would say, the Slats are what makes the 109, fast AND manouverable.

It is also a lot more neutral in a Dive.

It's a bit cool, the 109. Obviously not as cool as the Spitfire, but even so...

Well, I'm of the opposite opinion. Basically the 109 was a Fast Airplane made to turn well too, the Spitfire is a manouverable airplane that was made to go fast and manouverability suffered.

The Bf109 has more tricks than the Spitfire in my opinion,

-Fully automated engine controls in 1 lever, when the others still had at least 3

-Electric prop pitch control, when most others had Fixed, selectible, Hydraulic and Pneumatic controlled props which were heavier and more prone to damage

-Fuel injection, when others were carburetted

-Hydrocoupled High Altitude Blower, when the others had mechanically driven ones the Pilot had to shift manually, extremely good high altitude Performance.

-Inverted V12 which was more resistant to Ground Fire and offered a number of Comfort Advantages.

-Engine Cannon, which was more precise and didn't throw off aim as much. Allowed for much larger cannons (30mm Mk108)

-Large Capacity, Bomber based Engine for low Grade fuel and still high power output.

-Simple, small, slatted wings, the most simple, light weight wing of the War, easy to produce and replace.

-Super Leightweight Construction fuselage built from two Semi Monocoques, extremely robust

-Fully Adjustable Horitzontal Stabilizer, when others used simple tab trimmers.

 

And Goddamn, the 605 just sounds absolutely Badass, and it's quick as all hell. Only the Mustang could beat it in a straight line and none could keep up in a climb.

I wasn't being entirely serious. Because of my nationality, I'm genetically determined to love the Spitfire above all things always and forever. But despite this, I am getting to like the 109, paticularly the G2 that we have in game. It seems to do everything well.

 

But for badassery, I'll take the Merlin over the 605 any day of the week!

As a point of (pedantic) detail, there are no springs in Handley Page automatic slats (what the 109 had).

I bet the spit downed some 109s on beauty... you can't shoot at something so good looking without hesitating for a moment :D

I did not know that. By which mechanism were they deployed then?

The Slats do not have springs. In fact, the mechanics were to check the slats free movement on the Ground, in that they would remain in any position and move without any effort. They were purely actuated by aerodynamic forces.

 

I find this very soothing, towards 9 minutes they show slats.

uargs. that clipped wing looks as if the spit would have tried to fly through a too small canyon:P ugly!
