Hi,

I saw today the Rohr 2-175 in the topic "Jet trainers without jets", and I realized that Postwar deltas flying with propellers are not well known (at least by me ;D )

So I searched a first list of these planes. Among their the main are only prototypes (we are on SecretProjects ;) ). I am interested by all the others that you can add [but more "deltas" than other flying wings and canards or similar like ML Utility MkI (1957 : 65 hp), Rutan VariViggen (1972 : 150 hp), Miller Texas Gem (1973 : 100 hp), Velocity (1985 : 160 hp ?), Miller Bohannon JM-2 (1989 : 100 hp), Wingco Atlantica (2003 : 160 or 235 hp, crash during first flight), Chudzik CC-02 (2007 : 200 hp), Velocity V-Twin (2012 : 2 x 160 hp) or Raptor Aircraft Raptor (2019 ? : 300 hp)]

I like the Baker MB-1 and the Verhees Deltas D1/2. There is Payen's spirit in these planes :)

There's also that cranked delta that only flew as an RC model that was being proposed as a military trainer somewhere here at SP. It has tandem seating. I can't remember the name of it right now.

There was also the Lohr Deltaflügler - see https://www.secretprojects.co.uk/forum/index.php/topic,17943.msg196838.html#msg196838

Thanks. I did not know this project. Too bad that it did not have the opportunity to fly.

Eric, how could you forget to mention THE postwar delta with a prop, the Payen Pa.60/61 ?
https://www.secretprojects.co.uk/forum/index.php/topic,1417.0.html

Well, ok, much too obvious to be mentioned again ... ;D

Yes, "too well known". But thank you for this reminder ;)
 
It looks like more a Delta-canard, like the Rutan VariViggen, but thanks Hesham.

This one ? (AMR XD-110A : 1969)

Yes, that's the one.

H-5A Delta Stinger was/is a high-wing, low-aspect ratio, homebuilt designed by Continental Airlines engineer Lawrence “Larry” Heuburger. It probably never flew, but the prototype was recently spotted along a dusty road in the American South-West desert.
The wing had leading edges swept about 45 degrees while trailing edges swept forward a little (ala. Mirage).
The slab-sided fuselage sat a pilot in the nose, closely followed by a passenger. The engine was mounted high, amidships with an extension shaft connecting it to a pusher propeller. The deep fuselage included a rudder below the wing. A second rudder and fin were mounted above the wing. Fixed, tricycle, landing gear with spring-steel main legs.

H-5A had a tiny, horizontal trimming surface on the nose (similar to trimming surfaces on later Dyke Deltas).
There is a thread on the H-5A on www.homebuiltairplanes.com ....... started by our buddy Hesham..
I found the same photos and a 3-view drawing on Google.

Hopefully, a more tech-savvy poster can add links to those websites.
Pleeeeeeeease?

Heuburger later helped design the OMAC high-wing, canard, business turboprop. The first OMAC prototype had a delta centre wing, with constant-chord outer wing panels. After stability testing in a NASA wind tunnel, the revised OMAC got tapered wings.
 
Thanks riggerrob

Another one (new) project :

Schiffmann Aurora Delta :

not sure that it's the better shape (OK, amphibious...) to fly ... But, nevertheless, I like the look :)

Anyone know if it flew successfully?

After further research:


June 2013 :

the SRS Aurora. The SRS stands for Sticks, Rags and Styrofoam. It is loosely based on the Dyke-Delta with the additional capability of being amphibious. To accomplish this, Designer Gary Schiffmann positioned the 300HP Wankle engine on top in a pusher configuration. Gary has been working on this aircraft since 1981. He successfully built and flew a 1/4 scale RC model in that time. He is nearly finished and is in the process of filing his FAA paperwork. Gary hopes to fly the SRS Aurora later this summer.

Well... For the moment, still no proof/photo/movie of flight (according to the article, only the 1/4 scale RC model).

Latest news has it that Bart Ver Hees is not interested in manufacturing or marketing kits for his Delta 2. The good news is that Mr. Ver Hees is seeking a business partner to CNC kits and ship them to builders. This is a good business opportunity for someone who already owns a CNC shop.

A Ver Hees Delta 3 would be nice ... since VD2 already resembles the 4-seater Dyke Delta. Dyke seats 3 passengers across a wide bench at the center-of-gravity.
However, the biggest market sector is 2-seaters optimized for hunting $100 hamburgers.

Good news ! :)

Also hopefully, why not, a Delta 3 ;)

Cecil Goddard "Delta Wing".

Very good Retrofit ! :)

Maybe Cecil Goddard was this man in Mossbank-Saskatchewan-Canada:


One of the most eye-catching exhibits centers on a small airplane that is suspended from the roof. The plane was designed, built and flown by a local farmer, Cecil Goddard. Goddard built over a dozen different aircraft and flew them all with varying degrees of success. Some of his planes have been displayed in major airports and aviation museums, others, however, crashed with Goddard in them! Amazingly, despite his somewhat shaky flight record, Goddard emerged unscathed from every crash.

I found three photos of the plane, but it's not the delta. There are two photos sets around the plane, but they are too small to see anything...

A recent E-Pay buy of negatives yielded these two prints of the Stinger H-5. Found this info on a Flickr page with color photos of the Stinger "out to pasture" in Tucumcari, NM in 2008. "The Stinger was an original design of Mr. Larry (Lawrence K) Heuberger who started construction around the early-1960s. Prior to completion the project was acquired (around 1968) by Mr. Bud Rinker (Santa Barbara, Ca) who almost certainly did some limited testing in 1970. It is a two-seat aircraft and powered by a 140hp Lycoming O-290-G engine".

Bud Rinker performed the first flight in November 1969 but the aircraft was damaged soon after during a hard landing.
