Laminar flow wing

Who was the first to employ the laminar flow wing? I was watching "Wings of the Luftwaffe" and the show was on German guided and unguided "missiles." The V1 and the Henschel Hs 293 appear to have laminar flow wings, was this prior to the P51 and P63?

Don't forget that the B-24 used that wing design before the Mustang and any of those rockets came into being.

The B-24 has a Davis wing, not a laminar flow wing.

The Davis wing could actually be considered a laminar flow wing as it would exhibit laminar flow over 60% of the wing's chord although it was not designed as such. The P-51 is thought to be the first aircraft designed with a laminar flow airfoil. Laminar flow is more of a characteristic more than a specific design.

That is correct. The airfoil chosen for the Mustang is a laminar flow design but in practice on the aircraft this was not always true due to inconsistencies in the production process. True laminar flow demands a very slick surface that was not always achieveable with riveted aluminum construction unless "aerodynamic filler" (i.e. Bondo) was used.

I love that term "aerodynamic Filler". Laughed my a** off when I was told that no aircraft has bondo. It's aeroodynamic filler!

But there is a BIG difference! :shock:

you need to put the FAA PMA sticker under the 104

12V DC 60A Delco -Remy generator for your restored 1958 Chevy APACHE 1/2 ton pickup- $75.00 @ any auto parts store

12V DC 60A Delco-Remy generator for restored 1958 PIPER FLYCHASER, $ 750.00. The differences? The 'approved' generator has bigger gage brush wires installed, that are identical to the marine application Delco-Remy for a boat, marine applications also excessively high priced because it's 'a marine application'. :wink:

And an AEROSTAR 601 and LEARJET have around 300 lbs of 'aerodynamic filler'' on them. How much do you suppose is on a G-V? :roll:

First plane ever to have laminar flow wing is one US racer plane from 1923. This construction also incorporate integrated flaps and leading edge, similar to later F-104 design. All plane was of the laminated veener construction and from my point of view most advanced project ever built and flew but much more in front of its time.

FYI-

The Lear factory stopped using filler about 20 years ago, I've never seen filler on a Gulfstream.
