CURTISS PART 2
See Curtiss part 1

From Appendix 10: We found new illustrations of this brand's engines. Sharper and in some cases new to the author.

"Curtiss C-6"

"Curtiss C-6"(AEHS)

-The Curtiss C-6 was a redesign of Kirkham (from the K-6) for Curtiss .

"Curtiss R-600, Challenger"

“Curtiss R-1454” (AEHS)

"Two CD-12s with two carburetor assemblies"

-In the two previous photos we also noted that the CD-12 has a crown on a small wheel and an electric starter (as in cars).

-In the upper photo we see the anchor brackets of this electric motor uncovered. The CD-12 is mentioned in the main text without further information.

"New photo of a Conqueror with direct power output"

"Curtiss Conqueror with gear GV"

-The reference for the geared version was "GV-1550"

"The Conqueror GV-1550 seen from the other side"

-The next one was the "Super-Conqueror GV-1570 also geared, ie SGV-1570"

"Geared Super-Conqueror, SGV"

-We can also see that the two magnetos are on top of the gearbox.

"Better view of the magneto situation"

"New picture of the Curtiss D-12"

“Curtiss D-12-F” (AEHS)

"Recovered photos of a V-1400"

-This V-1400 is mentioned in the main text without photo.

"Supercharged version of the Super Conqueror"

-In the side view we see a mechanical supercharger of important dimensions, Dominant on the engine architecture.

"Super Conqueror SV-1570"

“Super Conqueror SGV-1570” (AEHS)

-The SGV-1570 had supercharger and  gearbox with superimposed gears. This is difficult to observe in the photo because the propeller shaft coincides with ducts in the front.

"Curtiss V-12, marine"

-See exhausts combined with water heaters - for services - and supplies.

"The Little Known IS-470 Crusader"

-It has six inverted in-line cylinders and is air cooled. It is destined for light and training aircraft, etc.

"Two more photos of the IS-470" (AEHS)

"Curtiss H-1640 Chieftain"

-Unpublished photo of the Chieftain from behind with its carburetor and intake ducts running in pairs between two Vs of each two inline twin cylinders. The other spaces between V's are for the exhaust outlet, in pair as well. The engine is air cooled.

"Chieftain H-2120, water cooled"

-With the same architecture for the two chieftains, the "small one" was air cooled and the "big one" water cooled. Each two-cylinder row had its camshaft at the cylinder head. A total of twelve cylinders in both engines.

“H-2120, side view” (AEHS)

-We located more engine material of Glenn Curtiss. First the 2 in V Note that the cylinders are used for the four-cylinder inline engine.

"Curtiss 2V, the A-2"

"The 2V on a tricycle"

“The four-cylinder Curtiss and an application"

-And also with the same or similar cylinders - or perhaps derivatives - they made the V8 that was better known and applied.

-They were air cooled and had a fan, before making the OX series, which were water cooled.

"Curtiss' first V8, the B-8"

"Fairly light, as we see"

"Another well-known Curtiss-V8 application"

"Curtiss B-8 (V8) with fan and free exhaust"

"The Curtiss OX-6 marine engine"

"A Curtiss engine that the author does not identify"

-A new collection of Curtiss engines found in American magazines of the time (1910-13).

"Possibly Curtiss C-4"

-The V8 also air cooled is shown in a different view than in the main text. It is the B-8.

"Curtiss V8 possibly with cylinders of previous engines"

-After these models they definitely switched to water cooling.

"The 24 hp, 4-cylinder, inline engine and its 50 hp, V8"

-Curtiss offered the engine with all accessories including the water radiator.

"4-, 6- and 8-cylinder engines with radiator and bed"

-Below we have the V-8 evolution in a few (3) years with the 75 hp "O" engine, which gave 85 hp at tests that were carried out in France, up to 200 hp in 1915.

"Curtiss 75-85 hp O model"

“Curtiss V8 giving 200 hp”
