Curtiss Aeroplane Co

Glenn Curtiss

Curtiss, who was a motorcycle fiend and engine genius, had actually asked the Wright Brothers if they wanted one of his 50 hp engines when he went to discuss some aviation data, but they said no, unaware that Curtiss and the AEA would soon be a major competitor.

Curtiss Aeroplane Co Article

As a member of Alexander Graham Bell’s Aerial Experiment Association (AEA), Glenn Curtiss built the engines for the Red Wing and the White Wing early in 1908, piloted his first plane, and built and flew the June Bug that June.

The AEA disbanded in 1909, and Curtiss formed the Herring-Curtiss Company on 20 March 1909 with Augustus Herring. Its first customer was the Aeronautic Society of New York. Curtiss delivered his first plane to them, the Curtiss No. 1, built to their specifications, on May 29, 1909.

When the Herring partnership split up, Curtiss founded the Curtiss Exhibition Company, the Curtiss Aeroplane Company in December 1911 in Hammondsport, New York, and the Curtiss Motor Company.

As business expanded, the Hammondsport factory became unable to fill all the orders. Curtiss extended its operation to Buffalo, where it rented the site of the company that had supplied Curtiss with his first bicycle engine years before. Curtiss also opened a new plant in Toronto. The quarters in Buffalo quickly became inadequate, and a new 120,000-square-foot (1,115-square-meter) building was constructed that became the company headquarters. Soon after, a new plant that sprawled over 72 more acres was added.

1909-early 1911 – While A, B, and C models are known (or thought) to have existed during this historically important period for Curtiss, where they were applied is not. Numerical assignments, as well, were guesses—Model 2 has appeared for both Rheims Racer and Charles Willard’s Banshee Express but not verified (Willard unjustifiably claimed authorship of that design). By 1910, Model D had been established, in some references tied to Curtiss-Herring, which was actually built after the partners’ dissolution. But there were at least 9 aircraft known to have been produced in this period, the “official” Model D, in one of its many forms, formally appeared in the first company catalog on mid-1911 along with its companion Model E. Production of concurrent Curtiss-Aero Society Model Ds unknown but the design quickly evolved into the Curtiss D (Standard). A Herring-Curtiss, for which plans were published for home-builders of the time, differed from Curtiss D with its ailerons on the front wing struts instead of the rear wing struts. Herring’s contribution, besides that as a temporary partner, was his alleged invention of a gyroscopic stabilization device (claimed, but unsubstantiated, 1909 US patent #12,256), which would circumvent the Wright’s aileron patents, but which was never used on any Curtiss machine.

Curtiss designed and built the following planes
during 1908 – 4,
1909 – 2,
1910 – 4,
1911 – 5,
1912 – 3,
1913 – 3,
total – 21.

In 1916, the Curtiss Aeroplane & Motor Company, Ltd. went public with Curtiss as president. By that time Curtiss had become the world’s largest aviation company, employing as many as 18,000 at Buffalo and 3,000 at Hammondsport.

The Curtiss Aeroplane and Motor Company was created 13 January 1916 from the Curtiss Aeroplane Company of Hammondsport, New York and Curtiss Motor Company of Bath, New York. Burgess Company of Marblehead, Massachusetts, became a subsidiary in February 1916.
In 1916 the company moved its headquarters and most manufacturing activities to Buffalo, New York, where there was far greater access to transportation, manpower, manufacturing, and much needed capital. It became the largest aircraft manufacturer in the world during World War I, employing 18,000 in Buffalo and 3,000 in Hammondsport, New York. Curtiss produced 10,000 aircraft during that war, and more than 100 in a single week.
A third factory (Garden City, Long Island, NY) became boat hull department for flying-boat production. Burgess Company of Marblehead, Massachusetts, became a subsidiary in February 1916. Aircraft built during First World War included A and AH biplanes for USN, Models D and E for U.S. Army, Model F flying-boats for USN, H-4 Small Americas, H-12 Large Americas and H-16 Large Americas (plus 150 by Naval Aircraft Factory).
Best-known were JN-4/JN-6 “Jenny” trainers (5,000 built, plus 1,200 by Canadian Curtiss), HS flying-boats, MF flying-boats, N-9 floatplanes, British S.E.5a fighters, Orenco D fighters, and 5L flying-boats. Total wartime was 4,014 aircraft and 750 aero engines.

After the war, Curtiss, fell on hard times. In August 1920, the company was forced into receivership. Clement Keys, a Canadian financier, obtained funds to manage the company’s debt and led it again to sound financial status. The Buffalo facility became the major facility, and the company remained the largest U.S. aircraft company through the 1920s.

Postwar production, mostly in 1920s, included NC- 1/2/3/4 transatlantic flying-boats (four only); Oriole, Eagle, and Seagull civil types (little success achieved with the few built). Followed by a series of Army (R-6/R-8 etc.) and Navy (CR/R2C/R3C etc.) racers. Twelve B-2 Condor biplane bombers were followed by PW-8 biplane fighters, P-1/P- 6 U.S. Army Hawks, F6C U.S. Navy Hawks, and O-1/11/39 and A-3 Falcons for U.S. Army. The few Carrier Pigeons and Larks were followed by one Tanager biplane, which won 1929 Guggenheim Safe Airplane Competition. Subsequently produced N2C Fledgling, F8C/OC Falcon, and F8C/02C Helldivers for USN.

Foundation of Curtiss-Robertson division in 1928 was followed by, on July 5, 1929, Curtiss Aeroplane and Motor Company became part of Curtiss-Wright Corporation, together with 11 other Wright and Curtiss affiliated companies.
In 1929, shortly before Curtiss died, the Curtiss Aeroplane & Motor Company, Ltd., merged with the Wright Aeronautical Corporation to form the Curtiss-Wright Corporation.

1930

Neither Curtiss or Wright successfully made the transition to the jet age and substantially all aircraft assets were sold to McDonnell and North American by 1950.

Cunningham-Hall Aircraft Corp

USA
Randolph F. Hall, with other ex-employees of Thomas- Morse Aircraft Corporation, formed this company at Rochester, NY, in 1928, in collaboration with the U.S. automobile company James Cunningham, Son & Co. First aircraft was a six-seat passenger transport (twin-engined PT-6), but only two built. Followed by Model X-90(N) tandem two-seat biplane with special high-lift wings, entered for 1929 Guggenheim Safe Airplane Competition. A developed version (also high-lift wings) led to GA- 21M all-metal monoplane in 1934, which reappeared after a year or so as GA-36 with Super Scarab engine. In 1937 built PT-6F biplane light freighter, a two-seat development of PT-6 with 512kg payload and Wright Whirlwind engine. Company ceased building complete aircraft and produced subcontract aircraft components for other firms during Second World War. It was dissolved in 1948.

Cunliffe-Owen Aircraft Ltd

UK
Cunliffe-Owen Aircraft Ltd was founded 1938 at Southampton Municipal Airport, Eastleigh, Hampshire, to build “flying wing” (lifting fuselage) aircraft based on Burnelli concept. First product was improved version of Burnelli UB-14 known as O.A.1 (two crew, 15 passengers). Second version (three crew, 20 passengers) designed as O.A.2, but not produced owing to outbreak of war. France acquired O.A.1 and used it in Africa during the war. Extensive subcontract work for Air Ministry undertaken, mostly “anglicizing” U.S. Consolidated Vultee, Lockheed, and Martin Lend-Lease aircraft for RAF. Late 1945 converted a number of Lancaster B.lll bombers for air/sea rescue. In 1946 began design of airliner, the Concordia 10-seat passenger transport, first flown May 1947. Prototype and one other built, but work suspended November 1947 owing to insufficient orders. Also built that year the prototype W.10 helicopter for Cierva; this project shelved too, and shortly afterwards company abandoned its aviation interests.

Cunard Steamship Co

UK
Cunard built factory at Aintree late 1917/early 1918 after receiving contract on November 22,1917 to build 500 Bristol Fighters. Production began March 1918, although in the previous month factory had been taken over by Ministry of Munitions and renamed National Aircraft Factory No 3. Production ended after only 126 aircraft completed.

Culver, Lagar

Lagar Culver of Salt Lake City had tested a biplane of his own design in early 1910, but due to lack of a suitable engine probably only as a towed glider. The 1911 monoplane was his second design but wasn’t satisfactory. A second biplane design was apparently also no success.

Culver

Culver was formed at Columbus, Ohio, in 1939 by K. K. Culver. Took over manufacturing and sales rights of Dart Model G two-seat low-wing cabin monoplane from Dart Manufacturing Corporation same year. First own product, the Cadet, was a two-seat light cabin monoplane (Continental flat four engine). In 1940-1941 developed two-seat Models LFA and LCA tourer, based on the Cadet, but with retractable landing-gear. Production ceased when America entered Second World War, company then doing subcontract work for U.S. aircraft industry. Moved to Wichita, Kansas, 1941, and concentrated entirely on producing radio-controlled pilotless aircraft based on LFA (nearly 2,400 produced) for use as PQ-8/TDC and PQ-14/TD2C gunnery target drones with USAAF and USN. When this ended in 1946, Culver began developing the Model V civil lightplane, first flown September 1945. Four built as drones designated XPQ-15. Company went bankrupt in late 1946; remaining assets acquired mid-1956 by Superior Aircraft Company.

CSS / Centralne Studium Samolotow

Immediately after the Second World War in Poland there was no favorable atmosphere for opening the aviation industry. Nevertheless, in 1946, on the initiative of Professor Franciszek Misztal from the Warsaw University of Technology, the Central Aircraft Study (CSS) was established in Warsaw at Okęcie. The CSS were a kind of design bureau that had its own workshop for building prototype aircraft. CSS, as part of the Aviation Industry Association, were not a factory.

At CSS engineer Franciszek Misztal gathered pre-war aviation engineers and young students.

In 1946, the CSS office received an order from the Ministry of Communications to develop 3 aircraft: school, training and aerobatic and passenger. In 1947, the first training aircraft project was developed, which was named CSS-10. The constructors of the aircraft were Franciszek Misztal and Stanisław Lasota.

Since the construction of the CSS-10 aircraft in the workshops in Okęcie was impossible, the construction of prototypes began at WSK PZL Mielec.

In 1950 transformed into the Communication Equipment Factory. No. 4 Warsaw-Okecie.
