René Couzinet Projects

[Avimimus]

In the Trait d'Union #186 (Jul-Aug 1999) is a surprising 5-engined canard Couzinet flying boat, and the 130H flying boat amphibian.

I'm rather curious about this design. Does the issue of the magazine have any dimensions or specifications? Any other leads?

The rc 100 a three engined seaplane ? I don't know

My dear Toura,

the Couzinet RC.100 was first allocated as you mentioned,later re-allocated to what we
know about RC.100 & RC.101 three engined light transport aircraft.

 

[toura]

All my thanks my dear Hesham

Hi,

the Couzinet RC.111 was a six-seat light transport airplane Project of 1933,
appeared in three variants with different engines.

 

[patvig]

Hi,

the Couzinet RC.50 (third allocated) to a single engined all-wing experimental monoplane
Project.

And a 4th allocated would have bee a 4 engine transport aircraft: http://alain.vassel.pagesperso-orange.fr/arc.htm

 

[hesham]

No my dear Patvig,

there was two companies formed by Rene Couzinet,the firm of 1926,Societe des Avions
Rene Couzinet and its series started from RC.10 to RC.200,also had RC.1000 and RC.2000,
followed in 1937 by new establishment,the Air Couzinet,which began with AC.01,and this
one was AC.50.

Hi,

the Couzinet RC.112 was a six-seat three engined light transport Project,based
on RC.110,also designed in 1933.

 

[hesham]

Hi,

the Couzinet RC.113 was a three engined six-seat light transport monoplane Project of 1933,
powered by three 135 hp Salmson 9 NC engine.

 

[hesham]

this "Elan" aircraft was called Couzinet RC.1000 as I remember,is that right ?.

Here is a profile drawing to it.

 

[Kdmoo]

Looking to see if there might be a better photo of the short-lived Couzinet 80. Only have this one.

 

[hesham]

two projects to Rene Couzinet,the RC.261 Normandie four engined
flying boat and a twin boom seaplane powered by two engined for
transatlantic mission.

Here is a drawing and a picture to AC.261 Normandie's Model.

The No.9 & No.10 were a Projects,but with unknown designations ?.

 

[blackkite]

Arc-en-Ciel No.1 _ Couzinet 10
Main wing area: 92.75m2, wing width: 27m, engine: Three V8 Hispano-Suizas. The output of each engine was increased from 180 hp to 200-230 hp. The fuel in the wing was stored in seven tanks, for a total capacity of 6,300 liters. An engine oil tank was installed in the fuselage, and the capacity was 280 liters. A retractable radiator for the engine mounted on the wing was installed next to the engine. The retractable radiator for the engine installed on the fuselage was installed on the lower surface of the fuselage (at the position of the leading edge of the wing). The oil cooler for the engine installed on the main wing was installed at a 45-degree rotation beside the engine. The oil cooler for the engine installed on the fuselage was installed on the underside of the engine. The propeller had two blades and a spinner.
Avions René Couzinet Paris, Moteur Hispano Suiza 180 CV markings on left and right sides of fuselage.

Arc-en-Ciel No.1 bis _ Couzinet 11
The engine was replaced with a V12 Hispano-Suiza 12Lb, 600hp. Fallen on August 8, 1928.

Arc-en-Ciel No.2 _ Couzinet 28 GR
It was 17m long and 30m wide. Burned down by fire at Mourdon on February 17, 1930.
Based on the 28, 29T (passenger aircraft), 29T (transport aircraft) and 29R (long-haul aircraft) were planned, and 1/2 scale models were produced.
The 29 F2 first flew on June 4, 1932, with a 450 hp Nome Rhone engine.
The 30 F1 (transport aircraft) planned in 1930 became the Couzinet 60, and the 30R (long-haul aircraft) became the Couzinet 70.
The 30 R1 was planned for flight between Paris and New York, and initially advanced the wing engine position assuming semi-retractable wheels. The width of the radiator was 0.80m.

Hi!　couzinet 11.

arc

 

[blackkite]

Hi! Almost same scale.
Mr.Couzinet tried to realize low drag economical aircraft for long distance flight using blended vertical tail stabilizer, wing blended engine nacelle, engine nacelle integrated radiator and blending wing body. It was a very advanced concept at the day.
Couzinet 71's tail became slim and wing blended to the fuselage very well.

 

[hesham]

Also from TU magazine,

Rene Couzinet had a Trimotor floatplane Project,but no designation number for it,just profile drawing,maybe
during late 1920s ?.

Arc-en-Ciel No.3 _ Couzinet 70 No.01
Production of the aircraft started in August 1930 and was completed in August 1931. She flew three times on February 11, 1932.
The aircraft had a total fuselage length of 16.13 m, a wingspan of 30 m, a projected height of the front of the fuselage of 2.10 m, a fuselage width of 1.80 m, and four trapezoidal windows on the left and three on the right. There were windows on the doors. There were landing lights on the underside of both wings.
Because the wheels were partially retracted, the position of the wing engine was advanced 40 cm.
The wing engine thrust line was parallel to the fuselage. The propeller was made of Nome Rhone and had three metal blades. The propeller was fitted with a sharp spinner.
There were no wheel spats. Only the hub had a fairing, and "ARC-EN-CIEL" was written behind the fuselage side window. After that, there were diagonal stripes of seven colors, and there were similar stripes on the outside of the wing.
The following statement was made in front of the horizontal stabilizer on the right side of the fuselage.

Arc-en-Ciel No 3bis _ Couzinet 70 No 01
The following major renovations were carried out for the Arc-en-Ciel No3 in the summer of 1932.
1. Changed engine support frame, engine cowling, and fuel piping.
2. The engine mounted position was moved to after direction by 40 cm.
3. The thrust line of the main wing engine was made 90 degree to the main wing leading edge, and it was shifted 3 degree to the fuselage center line.
4. Engine cowling was composed of four parts. Top cowling two open and close upward,
The bottom two cowlings were hinged and closed under the exhaust pipe.
5. Spats were added to the main wheels and tailwheels.

The flight resumed at the end of September 1932, shortly after, receiving the F-AMBV registration number. On the lower surface of the fuselage
There was a code letter for Ren's Couzinet. The character color was red as well as the example of the civilian machine at that time. At the beginning of December, the three propellers made by Nomrhone were retrofitted with two metal propellers made by Shoviel. The spinner tip has become rounded. On January 5, 1933, the propeller made of Choviere was changed to another metal,
No spinner. The propeller flange of the main wing engine is rainbow color, and the fuselage engine
is painted on tricolor. The character of the vertical tail of The Ren's Couzinet was covered with a glass ball.
At the end of 1932, a test flight of 27 hours and 46 minutes was carried out.

Arc-en-Ciel No 4 _ Couzinet 70 No 01
　In preparation for flights to America, a set of changes is requested in order to
improve the aircraft's flying qualities,mainly to increase its Handling:
Fuselage was a newly made one.(Arc-en-Ciel No.3 Length 16.13m ⇒ 21.45m, increased 5.32m)

1. Extension of the fuselage
   2. Repair of wing skin
   3. The steering cable was moved under the fuselage floor. (Previously the steering cable was located on the left side of the fuselage.)
   4. Increase of rudder area
   5. Changed the fuselage engine support frame from wooden to metal
   6.Increase engine oil supply
   7. Increase the area of cooling water radiator
   8.Renovation of engine cowling with radiator change
   9.Addition of expansion tank to radiator
   10. When the engine was removed, the speed reduction gear was installed at Hispano, and when the propeller became four blades, a very large fillet was added to the wing root.
   The cabin window was rectangular and the tip was elliptical. The landing lights remain unchanged under the wing. The width of the radiator was 1.10m. (It was 0.80m at 30R). The air outlet of the engine cowling has become an armored door. The expansion tank at the top of the radiator was cut into pears in half. On the upper surface of the wing, 10 oil fillers were installed.​

FRANCE AMERIQUE DU SUD is written upper the side window. The side windows are outlined in sky blue.

The registration number F-AMBV was written behind the circular window. There is a diagonal band of 7 colors, but unlike the Arc-en-Ciel No 3, each color was not adjacent. At the tip of the wing there was a diagonal band of three colors. The registration number was written on the upper and lower surfaces of the wing.On the underside of the fuselage was written René Couzinet. Test flight resumed in December 1933. The engine was a Hispano Suiza 12Nb type and had two propellers. At this point, there was no fillet at the wing root. During this time, the tail wheel was damaged and the spats were not repaired. At the end of December, the engine was removed and Hispano installed a reduction gear, and the propeller became four blades. Subsequently, a very large fillet was attached to the wing root. Two auxiliary vertical stabilizers were added to the horizontal stabilizer. This auxiliary vertical stabilizer moved in conjunction with the rudder

Arc-en-Ciel No 5 _ Couzinet 71 No 01

The vertical tail number became now 71. The fuselage was of Arc-en-Ciel No4 and the rear part was cut down by 1.25m, giving a total length of 20.18m. The first half of the fuselage remained. The fuselage shortening was performed behind the sixth bulkhead immediately after the cabin. In February 1934 the wing and fuselage were joined. A regular size fillet was attached to the base of the wing. During this time, the reduction gear was removed from the engine and returned to the 12Nb type. The propeller was two pieces of metal, and the spinner had a rounded tip. The engine cooling air outlet remained an armored door, but its shape was changed to allow airflow to the tail and engine cooling.
Four transatlantic crossings were made with this specification. The markings were the same as for Arc-en-Ciel No4, except the 71 number.
The letter R, Couzinet was added under the engineer's window.

 

[blackkite]

Arc-en-Ciel No 6 _ Couzinet 71 No 01

After the eighth transatlantic transit, the state bought the aircraft and lent it to Air France.
The tail markings are the same, the fuselage length is unchanged at 20.18m.

Major modification
1.Radiator moved from front of engine to bottom of engine.
2,Oil cooler moved from the engine side to the nacelle under the wing.
3.The radiator of the fuselage engine is approximately 45 degree offset left.
4.The exhaust pipe of the right wing engine was the same straight pipe as before, and the left wing engine
exhaust pipes were assembled for each bank and exhausted at the leading edge of the wing.
5.The exhaust pipe of the fuselage engine, they were gathered for each bank and guided to the lower left and right of the fuselage. Three triangles behind the fuselage engine
shaped air outlet.
6.The main wheel spats have been abolished, and a small cone that covers only the rear of the tire has been installed.
7.The propeller was a metal variable pitch Hamilton standard.

The marking on the vertical tail remained unchanged. The font of the body changes.
On the side window FRANCE AMERIQUE DU SUD characters were unchanged.
Above the left and right engineer windows, Arc en Ciel, the Air France mark on the bottom.
Next to the window was the word AIR FRANCE.
The gin cowling top is painted black. This aircraft was not used on regular routes.
Take the engine after removal, the aircraft was sold for public sale and purchased by René Couzinet.
In 1942 the German army built a factory.
During the occupation, the fuselage and other parts were destroyed.



No vertical tail stabilizer in front view.

Arc-en-Ciel No 7 _ Couzinet 71 M
M represents "modification". Refurbish a previously built aircraft and use it for flight testing before mass production was done.
The big change is the same type of spats as the Couzinet 10.

Arc-en-Ciel No 8 _ Couzinet 73
This is the first mass-produced machine ordered for three aircraft. The differences from 71 are as follows.
1. Wheel spats are back.
2. The engine cowling was the same type as the 71M.
3. Like the second version of Air Couzinet 10, the windows were upside down.
4. The wing area was reduced from 99m2 to 85m2, and the wing cross section was different.
5. The engine was changed from the Hispano Suiza 12Nb type to the 12Ybrg type (880 horsepower).
6. In order to shorten the overall width, four in-wing tanks have been eliminated (4th and 5th on the left and right). The fuel tank is not made of leather
Made of aluminum. The weight of each part was reduced by 900kg. The fuel capacity reached 8,760 liters (6,350 kg).
7. The actual fuel capacity of the Couzinet 71 was limited to 5,315 kg. 73 engine
Increased power capacity and increased speed to support trans-Atlantic
There was no obstacle. Maximum speed 325km / h, cruise speed 263km / h. Range when headwind is 50km / h
The separation was 3,306 km.
