Wilhelm Schult flying wings

[sienar]

"Wilhelm F. Schult was born in Winthrop, Massachusetts in 1895. He studied mathematics and engineering at Massachusetts Institute of Technology. In 1927, he moved to San Diego and began work for Ryan Aeronautical Company and other companies. In the 1930s, he began to do independent research in the design of flying wing aircraft. He built scale models and tested them in flight and in wind tunnels."

Great find Sienar.

My dear Jemiba,

the Wilhelm F. Schult was a well known designer,is that suitable to put it here or
Early Aircraft Projects section,specially after I found this link about him,(just question),
and here it's;

DONE !

Very interesting.
Many thanks, Sienar!

From the archives link above (Thank you Hesham!), we have the followings models:
Model S-1: Sail plane,
Model S-2: High Speed Low Wing Monoplane
Model S-5: Schult XP 800
Model S-6: Flying Wing Pursuit with Allison 1000 to 1600 H.P. ,
Model S-11: Flying Wing Pursuit with Allison 2400 H.P. motor
Model S-12: Heavy Bomber with 4 P & W Twin Wasp motors, 4000 H.P. ,
Model S-13: Heavy Bomber with 6 motors, total:19800 H.P
Model S-26
Model S-28: Six passenger transport
Model S-30: Target flying wing
Model S-32: VSTOL flying wing tilt-wing type
Model S-34: Single place sail plane (1968)
Model S-35: Sail plane,

Without model number indicated:
24 passenger flying wing (1939)
Flying wing interceptor (1946)
Pursuit or convoy escort, (1935)

Strange: Model S-13 looks quite similar to the Consolidated 1942 Flying Wing bomber project (here-under -Extract from "Les bombardiers americains 1917-1946_Fana HS n°58)
Has ever W. Schult worked for Consolidated?


What a pity San Diego is so far away from my place

Wow,I never thought like this,thank you my dear Retrofit.

A nice bit of logical sleuthing there, Retrofit.

As a matter of fact, Schult DID work for Consolidated during the B-36 development stages. As such, based on the research I've done to date for a future book title, I believe he was largely responsible for the flying wing alternate design for this project. I have quite a bit on the flying wing project, but have a friend digging through documents and photos for more info on this. I'm a HUGE fan of flying wings. I was responsible for the ERTL/AMT kits of the B-35, for which I also have a gigantic amount of stuff. One of the sheets in my collection turned out to be the ordinates for the wing from tip-to-tip, resulting in an extremely accurate kit shape.

I should have quite a bit more on Schult's flying wings before I'm done with this particular phase of research.

Good Info my dear Alan.

Someone asked about Consolidated's consideration of a flying wing as an alternative to its B-36 design...the report is dated May 8, 1942.

Better quality version of the art (from APR V2N3).

Sorry - meant to add some data to go with the image. The report ("Heavy Bomber Flying Wing, 6 Eng," Rpt. No. ZP-XM-001, dtd 5-8-42) includes a letter (H. A. Sutton to I. M. Laddon) which notes "on the basis of the figures only, the Flying Wing looks very promising...The big unsolved problem in this type of airplane is the one of providing adequate control." Sutton said that a model was under construction for tests in the Cal-Tech wind tunnel. Whether the tests actually occurred is unknown.

Here are some comparison data from the report; both designs used the "X-Wasp" engine, later P&W R-4360:

XB-36 (as of May 42) Flying Wing Design

Wingspan: 230' 288'
Length: 163' 78'
Gross Wt: 267,246 lbs 237,800 lbs
Max Range: 10,000 mi 10,000 mi
Max Speed: 378 mph 394 mph

Seems you have a copy of the report. Did it have a three-view?

Yes. Here 'tis:

We can recognize many airplanes here.

Indeed Hesham, on the above photos we have:
Schult S-06 (photos #4 & 8)
Schult S-11 (Photos #1 & 3)
Schult S-25 (Photos #2 & 9)
Schult S-13 & S-11 (Photo #3)

More on Wilhelm Schult (1895-1979):
Studied aerodynamics and aeronautical at Massachusets Institute of Technology. Worked at Ryan Aircraft Company in 1927. Also between 1927 and his retirement in 1960, he worked for other aircraft manufacturers in Southern California including Lockheed and Northrop.

List of his projects (knowned to me):

S-01 1933 4 passengers high-wing cabin monoplane
S-02 1934 Experimental racer monoplane
S-05 1935 XP800 pursuit airplane
S-06 1939 Flying wing Allison engine
S-11 1940 Flying wing military single seat
S-12 1940 BWB Blended wing body bomber 4 x engines / XB-36 alternative
S-13 1941 Flying wing bomber 6 x engines
S-25 1946 Flying wing interceptor jet engine
S-26 1947 Flying wing racer
S-27 1949 Flying wing 24 passengers 2 x turboprops
S-28 1955 conventional low wing 6 passenger transport
S-30 1958 Flying wing drone
S-32 1959 Reconnaissance tilt-wing flying wing
S-33 1963 New version of S-13 / XB36 alternative
S-34 1968 Flying wing sailplane

A lot of questions remains:
We know from Alan's post that Schult did work for Consolidated on the XB-36 Alternative. But there is a big gap in his projects numbering between his S-13 dated 1941 and his S-25 dated 1946: Was Wilhelm also involved in other Consolidated/Convair flying wing or tailless aircraft projects of that period such as the 4-engine bomber or the twin-engine maritine patrol land-based twin-engine aircraft, both studied in 1943.
The dates & nature of Schult's works at Lockheed and Northrop.
Project number (S-xx) of Hesham's photo #6
Information on missing project numbers in the list.

And a personal one: How to contact CalTech archives Dept?

Thanks in advance for any clue!

Many thanks my dear vRetrofit,

and maybe S-5 was intended to this competition;

Wilhelm (Bill) Schult (1895-1979) was a lifetime advocate of the "Flying Wing". His aviation career started in 1927 at Ryan Aircraft Company in San Diego, CA as an aeronautical engineer and designer. Mr. Schult worked in aviation until his retirement in 1960. During his career he never lost...

Oh my God,amazing and brilliant my dear Rolf,

and if someone can clear or make these drawings more obvious ?.

 

[sienar]

There are some additional pictures, and higher resolution versions of the SADM photos, on Alamy; https://www.alamy.com/stock-photo-wilhelm-bill-schult-collection-photo-15896856029-o-77341044.html

I noticed something interesting in this one. The rightmost aircraft looks near identical to Art Chesters "Swee Pea" Midget Racer, right down to the unusual kinked landing gear. Did Schult have something to do with that aircraft? Chester was living in San Diego during the 1940s.

From the link,and after your permission my dear Rolf,

also if can someone collects the pieces.

Before anyone misunderstands me, those pictures are not mine and I did not upload them at the SDASM Flickr website.

Schultz S-1 high-wing monoplane reminds us of the contemporary (Canadian-built) Noordyn Norseman, which was the best bush plane of its day (1930s). How did the two airplanes compare in performance?
Sadly, blueprints are too badly faded to read numbers.
Does anyone know the empty weight of S-1?
... gross weight?
... horsepower?
... payload?
... take-off distance?
... climb rate?
... cruise speed?
... range?

You can download a higher resolution version of most of the pics/drawings on flickr. I had to downscale this to make it small enough to upload here.
