Quick question about stall horns?

[Kazaa]

Did WW2 planes really have them?

The spit was reputedly prone to over wing noise as stall approached. Some folk replace the stall sound wave file with a buffet sound

Did WW2 planes really have them?

For what it's worth, I have WWII Training Videos of both the P-47 Razorback (I think it's a C) and the F4U-1(A?) and when both videos discuss stall charactersitics, neither of them mentions a stall horn, even when listing warning signs before a stall. Also, when the aircraft is filmed during a stall, I believe an in-cockpit clip is shown, and no stall horn is heard, though engine noise can account for that. However, from this, no I do not believe the average aircraft had a stall horn.

No. Nor did they have G-Meters. But they DID have hands on actual sticks mechanically connected to actual controls surfaces giving tactile sensations,  and actual butts in actual seats. So something must be done to compensate.  Remember, even with compensations, sims are still harder to fly than airplanes.

Kazaa in a real plane when the stall starts at the wing root you can "Feel" the airflow breaking up, becoming turbulent.
Both in the stick, and in the seat of your pants.

AH as a sim has all too few clues as to our planes behavior as it is.
So I totally agree with what BnZs said.  With no real world feedback, compensations have to be made.

Most airplanes exhibit some buffet that is felt by the pilot.  This is caused by the start of air flow separation over the wing root hitting the tail surfaces.  Here is a video showing the buffet on a Mustang.  In the Mustang it starts as a light buzz of the stick and gets more pronounced as you get closer to the stall.  In the B-17 it shakes...I'm talking knock your false teeth out shake.

Some aircraft dating to WWII, usually transports, were fitted with "stall shakers". Stall shakers are little more than vibrators installed to shake the yoke. These were switched on using simple paddle airflow switch mounted on the wing's upper surface, close to the leading edge. When the angle of attack reaches the point where airflow to the switch is disturbed or significantly reduced, there is insufficient aero loading on the switch paddle to keep the contacts open. When the contacts close, power is supplied to the vibrator. C-54s were fitted with a stall shaker system as were some Grumman amphibians.

Thanks guys.

There were no stall warning horns on any WW2 aircraft, only 'undercarriage not down' audible warnings. The Spitfire and Hurricane's operated when the throttle was closed to less than 1/3 open with the mainwheels still up, which drove the pilots nuts whenever they chopped the throttle to descend or slow down, so they disabled the device, leading to the loss of quite a number of aircraft when their drivers forgot to both reactivate the warning horn and select 'undercarriage down', hoho.

Hello Kazaa
Like some of the fellaz mentioned the planes would give a sign that it was about to stall.From what I have read and as Tilt mentioned the Spitfire was good for giving warning signs that it was about to stall.This enabled the pilots to push it to the edge with a certain amount of safety.On the other hand I have read of some planes that would give little or no warning and would just stall out when pushed over the limit.Those guys obviously had to be more careful how hard they pushed theyre aircraft especially when they were at very low altitude.The stall horn in AH is one of the substitutes for those warnings.

Well , that's good to know ...

In the movie "Battle of Britain" there is a scene where the pilot forgets to put the UC down. He got warned with a flare.
This actually happened to a pilot I knew. Same there, fire the Very-gun

Re gear not down. Lavochkins had a red pin that was pushed out (proud of) the wing when the gear was down. It was activated by a cam off the gear hinge point. The pilot had to look out across each wing to see if that gear was fully down or not. Cockpit indicators merely stated whether the gear down activators (hydraulics) were under pressure or not.

That's cool--I love simple solutions to complicated problems
