Dornier Do 29 STOL Light Aircraft

Caravellarella · 30 May 2011

Dear Boys and Girls, here is part of an article in French about the Dornier Do-29 V1 STOL light aircraft prototype which was apparently based on the nazi Focke-Achgelis FA 269 "project" of 1941. The rest of the article (edited-out) is about the Dornier Do-27 & Do-28 light aircraft......

The article comes from the 14th May 1960 issue of Les Ailes......

Thank you very much for sharing Terry!

Will it be possible to have higher resolution of the 3V and the propulsion system of this Do-29?

Dear Retrofit, it isn't a matter of increasing the resolution. Les Ailes was a weekly newspaper with a low print and paper quality. Each page is larger than A3, 43cm by 30cm; so the issue is trying to fit the articles into a document that will meet this website's requirements on size. The original resolution of Les Ailes is quite poor and please remember that I am constrained by dealing with oxidised and perished newsprint that is 50 - 70 years old......

Hi folks,
in the December 2011 issue of the French Magazine "Le fana de l'aviation" there is a very interesting article about the STOL aircraft Do 29. The article also has a company artist concept picture showing the Do 28C, a proposed (eight-seat?[1]) version with two Turbomeca Astazou II turboprops. Dornier used the fuselage of the Do 29 V2 for the Do-28C mockup.

By the way, the DO-29 was NOT based on the FA-269. Claudius Dornier had the idea of tilt-engines/props as early as 1921. (see patent drawings)

Caravellarella,

I am very much interested in the Do.29 and can't seem to find any good information on it's characteristics anywhere in my books. I am interested in particular in it's STOL performance (wing loading, stall speed, empty weight, takeoff gross weight, etc..). As you mentioned previously, the article is pretty hard to read. Could i bother you with a larger scan of the characteristics table or any other valuable performance point?

Thanks!

Avimimus · 29 November 2011

I'd think that the handling characteristics and pilot impressions would be quite interesting to hear about.

luedo34 · 30 November 2011

Well, my English is far from being perfect, but I will try to translate what I´ve got about the Do 29.
All in all, the plane was a disappoinment. A report from December 1959 states the following
Max. Speed: 230 km/h (planned were 330 km/h)
Landing speed: 70 km/h (planned 25 km/h)
Take off after 80 m (25 m were planned), 45 m for landing (again, 25 m were planned) .
After prototype V2 had an accident on 5th July 1962, the aicraft was written off.
Even though testing continued with prototype V1 until summer 1963, no further development took place.

AeroFranz · 30 November 2011

Landing speed certainly seems high for a STOL vehicle. No wonder you're mentioning disappointment! I have very fractioned and unverified pieces of information from a couple of websites that mention the Do.29 once flew as slow as 24 km/h. That's more in line with STOL performance, but I don't know how accurate the claim was

Jemiba · 1 December 2011

AFAIK, the Do 29 wasn't actually tested to its limits, because up to the end of this program,
there were problems with the propeller control. At first Hartzell props were used, later those
from Ratier, but problems remained at high prop angles.

AeroFranz · 2 December 2011

Interesting. Reminds me of the troubles the Ryan VZ-3 run into. It couldn't really hover in ground effect, so it was a failure as a VTOL. However it had very useful STOL performance. I would be curious to know what kind of performance goals the designers had set with the props at 90 degrees, and what they were able to achieve with the props at 60.

Jemiba · 3 April 2012

Eureka ! It was there, it still is there and I've actually seen it some years ago! Wasn't sure anymore,
as I couldn't find a clue, not even on the website of the "Luftwaffenmuseum Gatow" (airforce museum Gatow).
But someone else took a photo several years ago and now the Do 29 is stowed in a hangar there, that usually
isn't open to te public. Maybe I can make a visit in September, as then those "secret" exhibits are shown, too.

richard · 3 April 2012

I have seen it at Gatow too , but , I believe it is now at Dornier Museum Friedrichshafen... Or perhaps back to Berlin ?

Jemiba · 3 April 2012

Just had a look at the museums website (didn't this for quite a while ... :

), which is renewed and
lists the Do 29 as an exhibit now ( see http://www.luftwaffenmuseum.com/index.php?option=com_content&task=view&id=70&Itemid=178 )

And another photo even shows in in the new hangar, so it should stay in good condition for quite
a while now. Great news at close quarters. How could I miss that !

Hi,

day after day,I discover that Messier site is right,and many aircraft and designations we still
don't know it,the Dornier P.331 was early draft for Dornier Do.29 STOL aircraft.

Dornier Do 29, not D29.

Dornier D29 vtol concept of 1958

Much more than just a "concept", actually a flying prototype.

There is already a topic here with several photos and even scan of French-language articles:

If you have quotable data to back it up, you may want to correct the wikipedia entry at http://en.wikipedia.org/wiki/Dornier_Do_29 which states "was highly suuccessful"

gery · 22 May 2015

thanks jemiba....curious....it's look very efficient and powerfull...

I had taken these photos in the Dornier Museum in Friedrichshafen in 2010 - hope they are of use here:

The Model for Dornier Do.29 or P.331.

Hi, for fun I've started working on a computer model of this aircraft (I wanted to see what it would feel like to fly in X-plane).

I was wondering if anyone knows of a good source for references regarding the flight control system? More detailed dimensions, flap deflections would help etc.

It also looks like the ailerons are split (i.e. it has four ailerons - maybe some type of drag rudder arrangement)? Reliable information would help.
