sound radar is back ... naaaaaaah!

[TomcatViP]

I hve read it quite a couple of time. Might be in a Vought or Corsair story or reading some F4U7 pilot memoir (that version saw extensive service with the French Navy postwar)

Never read in any account thast it was the prop. I've always read it was the oil coolers. I know it makes the sound in level flight because I've heard it at Chino

. Let me know if you can give me a specific book. Thanks

Seriously, it is one of the worst bugs IMHO.

A cheap attempt a humor by me! Sorry!



About the F4U - I've read about the oil coolers causing the noise.

Concerning the current use of open cockpit (I presume in order to increase the benefits of sound radar as it works right now in the game): Actually I think with open cockpit it should be even less possible to hear other planes than with closed cockpit (where it is already impossible to hear one). Opening the cockpit not only would create more drag but also would reduce the smooth surface of the plane and creating buffeting. Together with the now more audible wind sounds from normal wind buffeting will increase the wind noise to another level which should actually increase the sound level beyond that obtained by simply removing a sound shield.

Up until I got my monitor calibration correct I was using open cockpit to improve dot visibility. It was harder to see through the canopy.

Since the last patch the wind noise make it unplesant to fly with the cockpit open for any length of time, though you do get better range of head movement with it open.

Can't say I've noticed the whine of the 109 with the cockpit open since the patch, Will listen out for it tonight!

Cheers!

I must admit I fly with the cockpit open because it gives a better rear view. I know its not realistic at high speed but its there and others will be using it, well on refllection not the 109 pilots! Johnny Johnson often wrote that he cleared his 6 by looking in his mirror and using 'coarse rudder' to swing the a/c left and right. Now if we had a decent mirror at decent resolution........ At the moment our ability to see a 109 on our 6 is too limited by the lack of a good mirror so I don't have any qualms about having the canopy open.

What's needed is a good mirror, then perhaps serious head buffet if beyond the limit of the canopy (or perhaps head restriction to cockpit-closed range?) above certain airspeeds. Say 150mph? Higher? It should be possible to open the cockpit and look around at lower speeds.

btw I have sat in a Spifire cockpit and it is possible to see about half of the tailplane by stretching the neck. Also there was a straps adjustment lever allowing the pilot more room to move (but you wouldn't in combat) and described here including a picture of a pilot with his head out of the cockpit but harness (loosely?) fastened:
http://spitfiresite.com/2010/04/the-...-spitfire.html

The seat belts used on the Spitfire and other British aircraft of the era are often being referred to as the Sutton Harness.
The Sutton harness commonly used during the initial to mid-war period consisted of four straps about 2” wide that had a row of grommets spaced about 1and 1/2 ” apart.
The shoulder straps of the harness were attached at a single point to a transverse cable which was attached by brackets bolted to the ends of the fuselage longerons behind the pilot’s head/shoulders. The length of the cable provided a degree of shock absorption upon impact. Also, the wire could be slackened by means of a lever in the cockpit to permit the pilot to lean forwards.

I hve read nearly a thousand of aero books. 80% of wich are not with me at present time. Are you torturing me wih that request ?

Looking at your vid, you can hear the whispering once only the plane did pass in front the observer (the cameraman) and not before. This means tht the whine is affected by mach hence the most probable prop related effect (if the LE was mach effected all the wing would be )

I will stand firm on that (no ego related - just logics)

Aces likes you shld lead others with exemplary behavior.

I confirm. But essentially that was meant to protect yourself behind the armored front glass panel (the only one protected glass surface). Don't forget that the seating position in those fighters were pretty much the same as we use today in front of our computer. It's perfectly natural to lean frwd to aim or (if we had too !) look above your shlder. The only restriction being the volume available bellow the hood.

Why sorry? I've laughed at it ... I just forgot a couple of smileys

Ouch!

Give me a proper mirror and I will
Modify the canopy-open effect and I'll have to!

Seriously, I'm not looking for an advantage, I'm looking to offset the lack of the mirror which atm is a disadvantage. The IL-2 mirror wasn't great but I could at least yaw the aircraft and see if there was something behind me.
