Curtiss NC

The Curtiss NC (Curtiss Navy Curtiss, nicknamed "Nancy boat" or "Nancy") was a flying boat built by Curtiss Aeroplane and Motor Company and used by the United States Navy from 1918 through the early 1920s. Ten of these aircraft were built, the most famous of which is the NC-4, the first airplane to make a transatlantic flight. The NC-4 is preserved in the National Museum of Naval Aviation, at NAS Pensacola, Florida.

Development

Manufacture of the "NC"s began in 1918 during World War I. The U.S. Navy wished for an aircraft capable of long ocean flights, both for Anti-submarine warfare patrol, and if possible with capability to fly across the Atlantic Ocean under their own power to avoid having to be shipped through ocean waters menaced by German submarines. This was a very ambitious undertaking, given the state of aviation at the time. The Navy and Curtiss came up with one of the largest biplane designs yet produced, equipped with sleeping quarters and a wireless transmitter/receiver. It was originally powered by three V12 Liberty engines, of 400 hp (298 kW) each; during the testing phase Marc Mitscher recommended the addition of a fourth engine to help create enough power to lift the boats out of the water. The fourth engine was added to the midline in a pusher configuration. The maximum speed was 90 mph (144 km/h) and the estimated maximum range was 1,500 mi (2,400 km). Called NC boats, with the "N" for Navy and "C" for the builder Curtis, they were nicknamed "Nancys".

NC-1 and NC-2 engine nacelle arrangements

As originally completed the NC-1 had three tractor engines in nacelles located midway between the mainplanes, the centre nacelle housing the cockpit for two pilots. Due to a lack of power the centre nacelle was raised, elongated forwards and a pusher engine added. With this engine arrangement the pilots cockpit was moved to the hull in a more conventional position.

NC-2 differed in having the centre engine, of its complenment of three, fitted as a pusher, retaining the pilots cockpit in the centre nacelle. Also suffering from a lack of power, the NC-2 was modified with four engines in tandem outer naelles, (due to the outer nacelles being built closer to the centre nacelle, the three tractor/one pusher arrangement was impractical). Initially the centre cockpit nacelle was retained but this was soon removed and a similar conventional cockpit to NC-1 was added.

NC-3 onwards continued with the later NC-1 arrangement of 3x tractor/1x pusher engines and conventional cockpit in the hull.

Operational history

On 4 October 1918, the first of these aircraft, the NC-1, made its first test flight with the early three-engine configuration. On 25 November, it flew again, with a world record 51 people on board. Armistice Day, signaling the end of the war in Europe, came before testing of the first NC and construction of the other three of the Navy's initial order had been completed.

The NC-2 suffered damage during the testing phase and was cannibalized for spare parts.

The other three NCs, NC-1, NC-3, and NC-4, set out on what was intended as the first demonstration of transatlantic flight, via Newfoundland and the Azores, on 8 May 1919. As junior officer, Mitscher, who had been allotted to one of the commands, lost his command when NC-2 had to be broken up for parts. He went on the flight as one of the pilots of the NC-1. The group met heavy fog off the Azores, making flight in the crudely instrumented aircraft extremely dangerous. Without a visible horizon it was extremely difficult to keep the aircraft in level flight. NC-1 tried different altitudes and soldiered on for several hours before eventually putting down just short of the Azores and was damaged beyond repair in the rough seas.

Only the NC-4 made it through. The crew of NC-1 was rescued at sea. Attempts to tow the aircraft to the Azores failed. NC-3 was forced to land some 205 mi (330 km) distance from the Azores, but the crew, led by Commander John Henry Towers, managed to sail her to Ponta Delgada unaided.

The Navy had two more sets of NCs constructed, numbered NC-5 to NC-8, and NC-9 and NC-10, up to 1921.

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
